The folks over at NoFilmSchool recently did a low light comparison of the Canon 5D Mark II, Canon 5D Mark III, and Nikon D800. The cameras were used to film the same dark candlelit scene with the same settings, and the ISO was slowly pushed up to the cameras’ respective limits. It’s pretty striking how big of a difference in low light/high ISO quality there is in the cameras, especially in light of DxO Lab’s test results for the cameras’ sensors…

Over the last couple of weeks we’ve covered every aspect of the Canon 5D Mark III “light leak” issue. Starting initially as a rumor, Canon eventually confirmed that the camera’s top LCD did, in fact, alter the exposure reading by 1/3 of a stop in dark environments. A week ago the company even put shipments on hold while they investigated the issue more extensively. Read more…
Camera rating business DxOMark has published its in-depth sensor review for the Canon 5D Mark III. For Canon fans, there’s both good and bad news: while the camera boasts the best sensor seen in a Canon DSLR so far — besting the sensor found in the 1Ds Mark III — its score of 81 is far below the Nikon D800′s 95. DxOMark does, however, point out that the two cameras focus on different strengths:
The duel between the Nikon D800 and the EOS 5D Mark III would most certainly take place except that the different sensors each one has adopted makes it difficult to do a head-to-head comparison. Both sensors offer different advantages —in principle, sensitivity for the Canon and definition for the Nikon. With its 36 megapixels, the Nikon D800 clearly has concentrated its efforts on fine detail reproduction.
For its part, the Canon EOS 5D Mark III chose to make a grand compromise: with its 22 megapixels, it offers both higher definition and in theory, higher sensitivity.

Canon has begun informing retailers in the UK and Canada (and probably other regions as well) that shipments of the Canon 5D Mark III have been put on hold as the company investigates the “light leak” issue that has come to light over the past month. Widely discussed in the blogosphere and on forums, the issue — which some have dubbed “leakgate” — is now known to cause a 1/3 stop error in exposure in very specific situations (i.e. scenarios that will not affect the vast majority of photographers).

Further to your enquiry we would like to inform you that we very recently (in April) have become aware of this and is now a known issue with the EOS 5D Mark III model. The AE sensor in the camera detects the light from the LCD panel when it is turned on and the exposure value will be altered. The change is not significant as it will be altered by approximately 1/3rd of a stop but can be noticeable. You can continue to use your 5D Mark III and the LCD screen can be turned off to receive the correct exposure.
The video above shows examples of what this 1/3 stop difference does for nighttime photographs. The issue definitely isn’t a huge one (don’t cancel your orders), but the 5D Mark III is a $3,500 camera and it’ll be interesting to see how Canon decides to deal with this flaw.
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.

Canon has officially taken the wraps off its new 5D Mark III DSLR, a followup to the 5D Mark II that offers a feature set that sits somewhere between its predecessor and the soon-to-arrive 1D X. The camera packs a 22.3MP full-frame sensor, the 61-point AF system found in the 1D X, 63-zone metering, an ISO range of 100-25600 (expandable to 50-102400), 6fps continuous shooting, a 3.2-inch LCD (1.04M dots), and 100% viewfinder coverage (up from 98%).
