Canon just produced a perceptible sound with its most recent answer to the discovery of a little problem described as “light leakage” on the Canon EOS 5D MkIII. Of course, the issue is not very large (see my previous comments) but Canon came back to their customers with a technical analysis that made quite a few eyebrows raise: No problem for your photos.
However, based on the results of extensive testing this change in exposure value will not noticeably affect the captured image.
This is right: the discrepancy seems to be limited to 1/3 of a diaphragm. This is not much. But the users of a camera designed for experts, enthusiasts and pros may appear more difficult to convince than the wider audience of entry-level cameras.
We’ll see what the final outcome will be. Maybe not a full-fledged scandal (Canon is still OK to check your camera up in After Sales if you feel this is critical), but some bitter comments and a mild irritation…
Important information (from Canon): The only cameras impacted by the issue have a serial number formed as “xxxxx1xxxxxx” or “xxxxx2xxxxxx” (please, notice the presence of the sixth figure which must either a 1 or a 2).
