[Review] Just Another Rebel? The T4i/650D As A Technology Sandbox

I have to say that I feel I am neglecting the Rebel T4i (EOS 650D in EU, Kiss X6i in JP). I am not part of the “just another Rebel” party, nor do I have an elitist approach to photographic gear. Nevertheless, I didn’t dedicate too much time to the latest Rebel (so far). That’s a shame, because Canon’s last iteration of the Rebel series (the xxxD series in EU) has a lot of advanced and cue-giving tech inside. So much that it should make us curios what it is about. I reported time ago that Canon may sandboxing and testing the technology (i.e. the touchscreen) that could possibly be used for its upcoming mirrorless system camera (expected for July 23). Now, there are more hints that the Rebel T4i/650D sports features and functionalities that would be more than just useful on a mirrorless camera.

Le me start saying that the T4i/650D is Canon’s first DSLR having full-time auto-focus in video mode. To accomplish this, you can use different focusing approaches, such as the contrast-detect method (used in previous Canon DSLR, slow and imprecise) or phase detection sensors in the camera (causes a blackout during live view, when the mirror flips down). But there is a third way to get auto-focus through phase detection: mixing phase detection sensors with pixels on the sensor itself. That’s what the folks at chipworks discovered when they tore down a T4i/650D. The cool thing is that such a technical solution would make up for a fast and reliable AF on a mirrorless camera. The technology is not new and was seen on Nikon’s Aptina sensor sported on the V1 and on the Fuji F300EXR. Differently from Nikon, which uses regular lines to implement the phase detection sensors, Canon uses an irregular pixel pattern. This is not totally new, as Canon two years ago published a patent for such a technology.

What are your thoughts?

Two Rebel T4i/EOS 650D Product Advisories

Right, two product advisories for the Rebel T4i/650D. First advisory concerns a phenomenon where the front rubber grips of some EOS REBEL T4i units produced in certain lots during the sixteen-day period between May 31st through June 15th, 2012 may turn white after a short period of time.

You can use the serial number to check whether your camera is affected by this phenomenon. If the sixth digit of the serial number is “1” please follow the procedure below. If the sixth digit of the serial number is “2” or higher, your camera is not affected.

Procedure:
1) Click on the link below to enter your serial number. 
2) Enter the 12-digit serial number (reference the image below) from your camera then click the Submit button
3) One of the following messages will appear.
            ·  “Your camera is NOT affected”   →  No further action is required 
            ·  “Your camera is affected”   →  Please see the Support section below

Next, the second advisory: your Rebel T4i might be a little confused sometimes, believing it is a Kiss X6i. :-)

Thank you for using Canon products.We have identified a phenomenon in which the camera model name embedded in the EXIF data of captured images incorrectly shows “EOS Kiss X6i”, which is the model name for the EOS Rebel T4i in the Japanese market. Even if this occurs, however, the image taken is still captured correctly.Phenomenon
When using applications, such as Digital Photo Professional (DPP) or Image Browser EX (IBX) to view images captured with your EOS Rebel T4i camera, the camera model name in the EXIF information of the images shows the model name for the same camera in the Japanese market: the EOS Kiss X6i.

The camera model name that appears on the Camera Settings / Remote Shooting screens of EOS Utility (EU) also shows “EOS Kiss X6i”.

Affected Products
EOS REBEL T4i Digital SLR Camera
*Some units whose second digit of the serial number is “3” are affected.
For example: ”x3xxxxxxxxxx” ([x] represents any optional number.)
