Canon Confirms “Light Leak” Issue in the 5D Mark III

Earlier this month, reports started emerging that Canon's new 5D Mark III DSLR has a "light leak" issue. Photographers found that turning on the LCD backlight in a dark room directly affects the camera's metering system (as seen in the video above). Canon published a product advisory today acknowledging the issue, saying,

In extremely dark environments, if the LCD panel illuminates, the displayed exposure value may change as a result of the AE sensor’s detection of light from the LCD panel.

The phenomenon [...] has been confirmed when using the Canon EOS 5D Mark III Digital SLR Camera. Canon is now examining the countermeasures and once the countermeasures are decided, we will post the information on our Web site.

Problem is, the issue isn't limited to the LCD's backlight in a dark room. Apparently any light (e.g. sunlight) shining onto the LCD screen can affect exposure.

Nikon D800 Resolution Compared to the Canon 5D Mark III

Last week camera testing service DxOMark announced that the Nikon D800 had earned the highest sensor quality score ever awarded. Roger Cicala of LensRentals wanted to see for himself how much of an advantage the D800's 36.3MP sensor had over its competition, so he did some sensor resolution tests on the camera, comparing it to the Canon 5D Mark III, 5D Mark II, and Nikon D700. His conclusion?

[...] there’s no question the D800 can actually get those pixels to show up in the final product (assuming your final product is a big print – they’re going to be wasted posting on your Facebook page). But you’d better have some really good glass in front of it. I don’t think the 28-300 superzooms are going to cut it with this camera.

In the real world, highest possible resolution is nice to know about and talk about, but usually not of critical importance compared to other factors. You’ll be able to make superb images with any decent lens for an 8 X 10 or even 11 X 16 print. But if you’re getting the camera because of the resolution, it makes sense to know which lenses will allow all of that resolution to be utilized. Just in case you get that job that needs billboard sized prints.

Canon 5D Mark III Spotted in Kenya?

Photographer Stephen Oachs over at Aperture Academy caused quite a stir yesterday after sharing some photographs he took of a Japanese photographer he spotted in Kenya. The photographer revealed that he was field testing a new Canon 200-400mm with a built-in teleconverter, but what caught Oachs attention was the camera body the man was using -- a Canon DSLR that he didn't recognize. He writes,

You can see it in the photos I took... I see the "Q" button located by the big wheel on the right, which on the 7D is currently located on the top left. The battery grip seems to have a joystick. I also noticed a "Rate" button...hrm, any ideas?

Is this the new 5D Mark III, or maybe the 7D Mark II? This info I was not able to determine.
