The EOS Scene Detection system can automatically determine the shooting conditions you are in, taking into account faces, colors, brightness, moving objects, contrast, and even whether the camera is handheld or on a tripod, and apply these technologies to create the ideal exposure. The camera then further analyzes the resulting images and applies a series of enhancing features in order to better render colors and skin tones.
Picture Style
Auto, Standard, Portrait, Landscape, Neutral, Faithful, Monochrome, User Defined 1-3
Advanced Imaging Features
Several image features allow you to manipulate the scenes in a variety of creative ways. Handheld Night Scene mode utilizes the multi shot noise reduction mode to allow you to shoot in low lighting and capture nightscapes with bright highlights and detailed dark areas--without the necessity of a tripod. By shooting and combining four consecutive shots at a shutter speed quick enough to prevent camera shake, Handheld Night Scene mode makes dramatic nighttime photography easy. HDR Backlight Control mode emulates high dynamic range techniques and extends the visual parameters of the image to include more shadow and highlight details in the image. It captures 3 consecutive shots at different exposures (underexposed, correctly exposed and overexposed) and then combines them, for a final result that preserves detail in both shadow and highlight areas for proper exposure. Seven different Creative Filters allow you to apply artistic effects directly to your images in-camera, including Grainy Black and White, Soft Focus, Fish-eye Effect, Toy Camera Effect, Miniature Effect, and now, Art Bold Effect, which makes photos look like an oil painting, with subjects appearing three-dimensional, and Water Painting Effect, altering images to look like a water-colored painting.
Additional Shooting Modes
Scene Intelligent Auto, Flash Off, Creative Auto, Portrait, Landscape, Close-up, Sports, Night Portrait
Lens Aberration Correction
An automatic corrective system can be employed in order to help reduce the effects of different lens aberrations. If there is light falloff detected towards the edges of the frame, the camera will automatically correct for this by evening out the exposure via the lens peripheral illumination correction feature. Additionally, a number of popular Canon lens' data is pre-programmed into the camera so it can quickly and automatically register settings according to the lens you are using. The T4i's chromatic aberration correction tool enables the correction of distracting color fringing at the time of shooting.
Feature Guide
A specific, helpful guide is integrated into the camera in order to help you learn about and determine which image settings to use in a given situation and how they affect your imagery. It is shown in each shooting mode, during mode dial operations, and for Quick Control screen functions, and appears automatically when a function is selected. This feature is enabled automatically, but can be disabled through the menu.
GPS Compatible
The Rebel T4i is compatible with the optional GP-E2 GPS receiver (not included). When connected to the hot shoe or through the accessory terminal, the receiver is capable of recording locational data, including latitude, longitude and altitude, to the metadata of your files for plotting to maps and reviewing your journey at home. You can even track the trajectory of movement with the receiver's logging function. An electric compass records the camera's orientation during every shot, and world time information is recorded via GPS syncing.
JPEG Resizing
You can conveniently resize your JPEG images to smaller formats in-camera. Keeping with the same aspect ratio and without modifying the original image, a new, smaller image will be saved to your memory card for expedited online use.
Photobook Setup
You can intuitively sequence and specify your images in-camera for printing out into a photobook. Your editing will be copied to a separate folder, ready for printing once at a computer.
Image Rating

Canon T4i

Canon EOS 650D/Rebel T4i In-Depth Review
August 2012 | By Amadou Diallo with additional material by Andy Westlake

Preview based on a production Canon EOS 650D with firmware 1.0.1
The Canon EOD 650D / Rebel T4i is the company's latest addition to its novice-oriented 'Rebel' series. With more than two decades of continuous success in its film and digital incarnations, these little SLRs have been improved and refined to the point that Canon's biggest challenge is finding new ways to distinguish its updated models. Place the new EOS 650D / Rebel T4i alongside its predecessor, the EOS 600D / Rebel T3i, and the similarity in design and specifications may suggest nothing more than a nominal upgrade.
Indeed the headline specifications - 18MP CMOS sensor, 9-point AF sensor, 3:2 flip-out 1.04m dot screen are all familiar from the 600D. Look a bit closer, however, and each of these has been significantly improved, with an eye both to more seasoned users who demand SLR performance and compact camera upgraders who want a familiar feeling interface. The 650D also gains significance because it forms the basis of the Canon EOS M, the company's long-awaited entry into the mirrorless interchangeable lens market.
It is largely because of the rise of large sensor mirrorless models that in today's market an entry-level DSLR must offer more than just high image quality to entice compact camera upgraders. In the age of YouTube, quick and easy access to video recording capability is a must. And for users that are far more familiar with composing via an LCD screen than a viewfinder, live view performance is of no small concern. Of course the camera must still offer users a path to a more traditional DSLR-like experience, without which, they would be hard pressed to resist the temptation of a physically smaller 'mirrorless' camera.
The EOS 650D is Canon's attempt to meet these challenges head on, with new features aimed at improving its live view and video performance. It becomes Canon's first DSLR to offer continuous AF tracking while recording movies.
This is made possible by Canon's new 'Hybrid CMOS' sensor that now includes pixels dedicated to phase detection autofocus. The Hybrid AF system uses these to quickly set the lens to roughly the correct distance, then uses contrast detection AF to fine-tune focus. In theory, this should provide faster and more certain focusing for live view and video shooting compared to previous Canon models which rely on CDAF alone. You can read a more detailed explanation of this technology and see it in action on the AF performance page of this review.
The EOS 650D also becomes the first SLR from any manufacturer to feature a touchscreen. This is of the capacitive (contact sensitive) rather than resistive (pressure sensitive) type, behaving like that of a typical smartphone. In Live View and Movie modes the screen can be used to specify the point of focus and (optionally) release the shutter. It also supports iPhone-like multi-touch and gestures. The rear screen has been redesigned with no air gap between the display and cover glass in an attempt to reduce reflections and improve visibility in bright light. There's also an anti-smudge coating which aims to reduce the impact of its newfound touch-sensitivity.

Canon EOS 650D / Rebel T4i key features

  • 18MP APS-C 'Hybrid CMOS' sensor
  • Phase detection AF from imaging sensor for Live View and Video
  • Continuous autofocus in movie mode with subject tracking
  • 14-bit DIGIC 5 processor
  • ISO 100-12800 standard, 25600 expanded
  • 5 fps continuous shooting
  • 9 point AF system, all sensors cross type, central sensor F2.8 (from 60D)
  • 63 zone iFCL metering
  • 1080p30 video recording with built-in stereo mics
  • 1.04m dot 3:2 touch-sensitive vari-angle ClearView II LCD (capacitive type, multi-touch support)

Additional improvements

The EOS 650D uses Canon's DIGIC 5 processor (as seen in the S100 and G1 X compacts), which helps enable a boost in the sensitivity range to ISO 12,800 (25,600 extended), and allows lens-specific corrections for chromatic aberration and vignetting in the camera's JPEG processing. The 'conventional' autofocus system for eye-level shooting is borrowed from the EOS 60D, and uses nine focus points which are now all cross-type, with the center point offering additional accuracy with fast lenses.
The camera also gains a built-in stereo microphone to provide sound for video, while retaining its predecessor's external microphone input. There are a couple of new scene modes, 'HDR Backlight' and 'Handheld Night Scene', both of which combine multiple exposures to give a final processed image. A four-exposure 'Multi Shot Noise Reduction' setting is also available in the PASM modes.
As is Canon's way, the EOS 650D doesn't directly replace the EOS 600D in the overall lineup. Instead the older model will remain in the line and effectively drop down a notch to the position currently occupied by the EOS 550D / Rebel T2i, which will be discontinued.

'STM' lenses: EF-S 18-135mm f/3.5-5.6 IS and EF 40mm f/2.8 pancake

Canon EOS 650D with EF 40mm f/2.8 STM (mounted) and EF-S 18-135mm f/3.5-5.6 IS STM
Alongside the EOS 650D, Canon has introduced the 18-135mm f/3.5-5.6 IS STM zoom and EF 40mm f/2.8 STM pancake lens. These two optics both use linear stepper motors for autofocus, hence their 'STM' designation. This type of motor is commonly used in lenses for mirrorless cameras as it offers the potential for fast, silent focusing during video recording, and is especially well-suited to working with contrast detection AF. However, this marks the first time this particular technology has been used in a conventional SLR system. Both lenses feature 'focus-by-wire' manual focus - as opposed to mechanically-coupled focus rings - and allow for full-time manual focus when the lens is set to AF mode, although only while the shutter button is held in the 'half-press' position.
The 18-135mm f/3.5-5.6 IS STM is an EF-S lens for APS-C cameras that also features 'Dynamic IS' image stabilization, designed to compensate for the different patterns of camera movement encountered when shooting video (for example when walking with the camera). It is one of the EOS 650D's 'kit' lenses, along with the cheaper EF-S 18-55mm f3.5-5.6 IS II. It's a little smaller than Canon's existing EF-S 18-135mm f/3.5-5.6 IS lens, and adds a helpful switch to lock the zoom at 18mm and prevent it from extending under its own weight when you're carrying it around. It's close-focus distance is also reduced to a pretty reasonable 39cm. Most significantly - for video shooters at least - this is the only kit lens option that is actually silent while focusing.
The EF 40mm f/2.8 STM pancake, meanwhile, becomes comfortably the smallest lens Canon makes, at about half the thickness of the EF 50mm f/1.8 II. It will also be sold as a kit with the EOS 650D in some regions (where it offers a slightly unconventional 64mm equivalent field of view), but Canon says it's aimed at least as much at EOS 5D Mark III owners. Indeed we can see it becoming a firm favorite with full-frame users, for whom it will offer a slightly wider than normal angle of view. One thing we dislike about its operation is that you can't retract the lens from an extended position without putting it on a powered-up camera, and the lens doesn't retract when the camera is turned off.

When shooting through the viewfinder, the EOS Rebel T4i has improved autofocus with a new 9-point, all cross-type AF system (including high-precision dual-cross f/2.8 center point) for accurate focus whether the camera is oriented in portrait or landscape position. A new AI Servo AF system achieves and maintains consistent focus with an exceptional degree of reliability.
The EOS Rebel T4i features Canon’s amazing new Hybrid CMOS AF System, perfect for shooting photos and video in Live View. This new system combines two distinct AF technologies, phase and contrast detection AF, for speedier and more accurate focus. These complementary focusing systems are aided by pixels on the camera’s CMOS sensor that assist in predicting subject location; therefore making continuous focus tracking quick and accurate in video recording while enhancing focusing speed.

Built-in stereo microphone, manual audio level adjustment
The EOS Rebel T4i has an internal stereo microphone for improved audio capture and a wind filter feature to reduce wind noise when shooting outdoors. Sound recording levels can be manually (up to 64 different levels) or automatically controlled. A built-in attenuator is also provided to reduce audio clipping. For more advanced audio recording, the Rebel T4i is compatible with many third-party electret condenser microphones with a 3.5mm diameter plug.
Video Snapshot
With the Video Snapshot feature, the EOS Rebel T4i DSLR can capture short video clips (of 2, 4 or 8 seconds) then combine them automatically into one video file as a snapshot or highlights “album.” With no editing needed after shooting, the compiled video is perfect for sharing online or displaying directly on an HDTV via the camera’s HDMI port. Additionally, stills can be recorded during video shooting simply by pressing the camera’s shutter button. During playback, video clips in an album can now be reordered or deleted.

Sharp and Clear, with Tactile Controls

New Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II with multi-touch operation and Touch AF
The EOS Rebel T4i comes with a newly engineered, Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II. Using the same capacitive technology as today’s popular mobile devices, this new screen is touch-sensitive and delivers intuitive touch panel operation. Two finger touch gestures (multi-touch) can be used for zooming or changing images, menu and quick control settings can be accessed, and focus point and shutter release can be activated with the touch of a fingertip. Displaying fine detail (at approximately 1.04 million dots), this screen is perfect for composing and reviewing images. Thanks to a new, solid construction between the monitor’s resin-coated cover and the liquid crystal display, reflections are minimized, and the display can be viewed, without glare, from any number of angles. The LCD’s surface is treated with a smudge-resistant coating to minimize fingerprints and maintain a bright, clear image display.

Complex Functions Made Simple

Scene Intelligent Auto mode
The EOS Rebel T4i features an enhanced Scene Intelligent Auto mode that incorporates a number of Canon technologies to deliver the best possible exposure. Joining Picture Style Auto, Automatic Lighting Optimizer, Automatic White Balance, Autofocus, and Automatic Exposure, Scene Intelligent Auto mode analyzes the image, accounting for faces, colors, brightness, moving objects, contrast, even whether the camera is handheld or on a tripod, and then chooses the exposure and enhancements that bring out the best in any scene or situation.

New Effects for Dramatic and Gorgeous Results

EOS Rebel T4i
Handheld Night Scene mode
Accessible right on the EOS Rebel T4i’s Mode Dial, Handheld Night Scene mode captures nightscapes with bright highlights and detailed dark areas, delivering results previously impossible without the use of a tripod. By shooting and combining four consecutive shots at a shutter speed fast enough to avoid camera shake, the EOS Rebel T4i’s Handheld Night Scene mode makes dramatic nighttime photography simple.
EOS Rebel T4i
HDR Backlight Control mode
The EOS Rebel T4i’s HDR Backlight Control mode ensures that backlit subjects are not recorded too dark. By shooting three consecutive shots at different exposures (underexposed, correctly exposed and overexposed) and then combining the images, the final result maintains detail in both the shadow and highlight areas, ensuring the backlit subject is properly exposed.
EOS Rebel T4i
Seven Creative Filters, plus new Art Bold Effect and Water Painting Effect
To add to the fun and creative possibilities available with the EOS Rebel T4i, seven different creative filters that can dramatically alter the mood and visual effect of any particular scene. Creative Filters include Grainy Black and White, Soft Focus, Fish-eye Effect, Toy Camera Effect, Miniature Effect and new filters, Art Bold Effect (makes the photos look like an oil painting, with subjects appearing three-dimensional), and Water Painting Effect (photos are altered to look like a water-colored painting). Since the filters can be applied to the image after shooting, it’s easy to try several effects on the same shot.

Cleaner Images, Even at High ISO

Multi Shot Noise Reduction
To enhance its already admirable high ISO shooting capabilities, the EOS Rebel T4i features an intelligent Multi Shot Noise Reduction tool that reduces noise even further than the camera’s sensor and the DIGIC 5 Image Processor alone. With Multi Shot Noise Reduction activated, the camera takes four consecutive shots, merges and aligns them. This eliminates more noise than the Rebel’s traditional Noise Reduction filter, with little or no apparent resolution loss. Moving subjects are even optimized to minimize subject blur! Thanks to this clever new feature, high ISO shooting has never looked better.

Flexible and Reliable Recording

Compatibility with SD/SDHC/SDXC memory cards, including new Ultra High Speed cards
The EOS Rebel T4i uses popular SD, SDHC, SDXC and is even compatible with the newest Ultra High Speed (UHS-I) memory cards. Compact and available in large capacities, SD, SDHC and SDXC memory cards are a perfect complement to the EOS Rebel T4i’s compact design.

Canon T4i vs Nikon D3200



Overview: Entry-level Nikon, Cost  = $699 includes 18-55 lens with VR (image stabilization) Comes in Red or Black with 3″ LCD screen, Battery life rated at 540 shots
Still info – 24MP, ISO Auto – 6400 (12,800 w/ boost), 11 focus points, center point is cross type(most accurate), 4 frames per second
Video info - 1920 x 1080 (30,25, 24 fps), 1280 x 720 (60, 50 fps), 640 x 424 (30, 25 fps), Mono Mic with external mic jack, continuous AF during filming.
My Thoughts – The sensor in the Nikon D3200 is excellent, one of the best crop sensors ever tested by DxO mark folks, second only to a pentax.  The built in guide mode does a good job of holding your hand and teaching you the basics of DSLR shooting while actually using the camera.  Still lacks an in body focus motor which means that it will not Autofocus with all nikon lenses, especially older ones but I think this is much less of an issue than I made it out to be three years ago.  The video focus is on the slow side and it can certainly hunt for for focus while filming, this can be heard through the on board mono mic.  Using an external mic will obviously give you much better audio and lessen the noise from the lens as it focuses.  Buy this is you care more about stills and want video as an after thought.  For $700 you are getting some excellent image quality (IQ) but to really take advantage of it you will need to consider other lenses like the affordable but excellent quality 35mm f/1.8

Overview: Step above entry-level, Cost $949 includes 18-55 lens with IS (image stabilization, comes in black with 3″ articulating touchscreen, Battery life rated at 440 shots
Still info – 18MP, ISO Auto – 12,800 (25600 w/ boost), 9 focus points all cross type, 5 frames per second, wireless flash control
Video info - 1920 x 1080 (30, 25, 24 fps), 1280 x 720 (60, 50 fps), 640 x 480 (60, 50 fps), Stereo Mic with external mic jack, continuous AF during filming (silent when paired with the two new STM lenses)
My Thoughts – Canon has now produced three Rebels at the 18MP mark, this sensor is paired with a new processor allowing for better high ISO images and has the added benefit of phase and contrast detection which makes focusing while video faster and more reliable.  That coupled with the new STM lenses, one of which is quite affordable, makes this a potentially very exciting video machine for pros. Parents should also appreciate the stereo mic, you don’t need any extra doo-dads to get good audio.  If you have an older Rebel and or a collection of Canon lenses it is certainly a worthy upgrade and offers both still shooters and budding videographers lots of room to grow but the D3200 is going to give you better image quality and slightly better high ISO for $250 less.  You are giving up the articulated touch screen, better video with stereo and the ability to focus silently if you pick up those STM lenses in the future.

Final Thoughts – It is difficult to discuss these two cameras in a vacuum, there are plenty of other offerings in the price range of $650 – $1000 that will get you similar features.

Canon Rebel T4i / 650D – Introduction


Canon Rebel T4i / 650D – Introduction

The Canon T4i is the latest addition to Canon’s EOS camera lineup.  Since the EOS 300D, the xxD DSLR cameras are the most popular DSLR cameras in the world, and what gave Canon its great success in the digital photography business.
In a nutshell,The T4i/650D is equipped with a 18MP Hybrid CMOS sensor (will talk about this soon), 14-bit DIGIC 5 processor, ISO 100-12800 (expanded up to 25600), 9-pont AF sensor, a large 3-inch 1.04M-dots vari-angle Toucn-Sensitive display with multi-touch support. The camera can shoot at 5 fps in burst mode and record 1080p30 videos with stereo sound and continuous autofocus with subject tracking.
Canon really wanted to take this 650D / T4i not one step, but a few steps forward. The competition from Nikon’ DSLR cameras and the Mirrorless cameras don’t make the life any easier. Canon had to come up with a vastly improved camera in order to convince photographers that it  can innovate like the other companies. I personally think that beginners and enthusiast photographers just won’t accept any other average DSLR camera. It has been too long since we’ve seen Canon implementing unique features in its entry-level cameras. I was even convinced that it’s better for many people to grab a Micro Four Thirds over an entry-level DSLR. Can Canon make us re-think our decision and purchase the new 650D / T4i over the competition?
Upper Entry-level cameras like the 650D are targeted to beginners and enthusiast alike. People that might want to start with a less expensive camera and update as they grow. The Canon already has the 1100D, it’s most basic DSLR camera. The T4i is certainly a few steps a head of that model, and with its new features, it really looks like a completely unique camera in the EOS lineup.  The all idea is to have a camera with all the features that enthusiast might want, although not in the same build-quality and performance of the more expensive models (ie. 60D, 7D, 5D Mark III, etc.).
My first DSLR camera was the 400D, and I had such a great time shooting with it. Of course we’ve become spoiled when it comes to features. Most of us don’t need all the latest specs to shoot great images, but let’s admit it, there are here because they are useful, cool and can help beginners shoot better photos and videos too. In the days of mobile phone cameras, it seems that you need to put out more innovative products that can convince people to purchase your new products. The touch-sensitive screen is one of those features.
OK, let’s take a look at the Canon Rebel T4i / EOS 650D key features and see why you should be excited that this camera is released

STILL WORKING OUT THE DETAILS!


STILL WORKING OUT THE DETAILS!

So you’re ready for a new consumer DSLR? Me too! I’m excited by a few rumors which I’ll cover in this Canon T4i review, maybe T4i preview would be more acurate? I’ll stop asking questions now and get on to what I’ve learned about this new camera.
The first feature I think about when I ask myself what’s missing from the T3i is an autofocus option while in video mode. I mean really, are consumer camera buyers expected to be able to focus on the fly, especially with some of the previous lenses that made manual focus pretty awkward. My fingers are crossed on this one, come on Canon!
Speaking of the lens… The word on the street is that a new version of the 18-135mm EF-S kit lens will be available along with the Canon T4i. This new lense is supposed to have silent autofocus. Personally I don’t care about silent focus, I just want great image quality and smooth operation. But I’m just one person writing a Canon T4i review, I suppose some photographers are concerned about the amount of noise their equipment produces.
There’s been reports of a new 24 MP sensor along with the DIGIC-5 image processor. In respect to DIGIC-5, bring it on! As for a 24 MP sensor… whatever. The old 18 MP is plenty for nearly any application this camera could be reasonably expected to handle. I’d just like to see reduced noise when shooting in low light with higher ISOs and a higher resolution sensor won’t be helping with that. When I actually get one of these in my hands my Canon T4i review score will depend highly on high ISO noise performance – I’m not a fan of flash. Lucky for me, the more recent reports claim that the T4i will retain an 18 MP sensor. We’ll have to wait and see on this one.
Now to the touch screen display. WHAT?!?! Yep, you heard that right, touch screen display! I don’t know if I care or not. I mean sure that sounds cool, but will it improve the experience or just be annoying? If it works as well as, say an iPhone, then bring it on. But if it’s going to be “iffy” I’ll stick with the directional pad and buttons. Not that a touch screen would mean you’d lose these things, of course.
It seems like everything these days has WiFi. I’d love to tell you in this Canon T4i review that WiFi will definitely be included. I can’t quite do that, but what I can do is say that it is HIGHLY rumored to be (whatever that means)! I would love to be able to access images on my Rebel T4i without searching for cables and going through that process… It just makes so much sense. Come on Canon, I really want this one!

ENDING THE CANON T4I REVIEW

To sum things up, the best guess about the T4i’s features is currently: a new silent lens with an awesome focal length range, a fancy touch screen display, DIGIC-5, and WiFi! I’m sure there’ll be some new video features thrown in there as well.
What Canon T4i review would be complete without a little intrigue? A Canon EOS 650D book was mistakenly released for pre-sale on Amazon recently, with a release date of May 17th. Of course it was promptly removed once the mistake was discovered! To me that means we’re looking at a Canon T4i release date on or before May 17th!
