More reports - Re: 5D mark III light leak?
In reply to S Hoekstra, Apr 10, 2012

No matter who posted it, if it's good information then it is always good to know any bug and issue found on any camera , be it Canon, Nikon or whatever. We're users of these cameras, so we deserve to know.

Here there's a more updated report with many video examples, pictures and links:

http://www.hdcamteam.com/2012/04/07/eos-5d-mark-iii-light-leak-issue/

I hope Canon let us know their official word and solution soon.

Thanks to all the people reporting this kind of information, they help us to get faster responses from manufacturers.

What I can't tell from any of this discussion is this:

Is the extra light affecting the exposure or is it just affecting the metering of the exposure?

In other words, testing should be done in manual mode as well...

Another interesting observation I found was that if you also turn on the AF point selector which illuminates the prism with red light (depending on how your have it configured) and then watch your meter it dramatically jumps up from the red light then back down again as it shuts off that red light.

In manual mode I can still see the shifts discussed. With the lens cap on and eyepiece cover the meter sees about a 2/3 of a stop increase when the top LCD backlight is engaged.

The meter reading under dark situations (lens cap off) seems most effected when using shutter speeds in the seconds rather than fractions of a second.

I wonder how the amount of light that creeps in through the eyepiece as you shoot effects this as well. Without the eyepiece cover in place, aiming stray light into the prism seems to dramatically change the meter reading too.

The best thing is to wait for a statement of Canon.
Right now we are all guessing.

Once and for all Light leak does not affect exposure!!
In reply to S Hoekstra, Apr 11, 2012

Tired of reading and wondering if the light leak from the lcd display light affect exposure so I decided to do some tests. If you do't belive me tests your camera for your self.

When I read the post that the lcd light affects the metering with the cap on I tested it and mine changes with the light on or using a flash light on the lcd panel. Now I was patiently waiting for a statement from canon but rather than wait I did tests my self.

I set the camera to av and iso 1600 under a daylight 6000'k bulb exposure read 1/125th at F4.

I press the lcd light no change in exposure, so I turn on my high powered led(cree) flashlight covered the viewfinder with a cloth and shined the flash light it on the lcd panel and guess what exposure stayed EXACTLY the same.

Read on another post where a owner of a 5D III was under exposing good thing that he did not listen to the know it all and got the camera exchanged.

If you take a photo of a 12 or 18% grey card or any light color wall the exposure should at or very close to the 0ev. I just did this tests.

Using dpp the exposure should not be -1/3 or -2/3. It should be at the 0 mark or brushes just below. I read where people said on the xti they had to dial in +2/3 well your camera had a under exposure issue and you should have sent it to canon to have them calibrate the metering. If you did that meant you listen to the know it all on here and they are wrong. I had one sent it in and it came back perfect.

I can tell you every camera that I have ever bought I run through focus and exposure tests. from the Xti, Xsi, 40D, 50D, 60D, 7D, 5D II and 5D III.

Every camera is just at the 0 ev mark or just brushed lower against the 0ev. This is in any metering mode.

It seems you didn't watch some of the example videos nor read the full information on those reports!

Some of the tests were done with lens cap OFF...

Check it again.

I did read the same result in similar situation.

My question in this case is: what happen if you cover the top LCD panel in the exact same situation (sunlight)? Does the metering shift or keep the same?

I assume it will keep the same, but am not 100% sure since I don't have the 5D3 yet!

Please let us know if you do the test!

Thanks

well, not exactly. We're testing and retrieving information.

That's how Canon gets aware of bugs and issues in lot of cases.

Let's hope Canon do a deep investigation and bring some solution

Maybe you didn't spend some minutes carefully checking the tests, reports and video...

Here you have a very detailed one with pictures , in case you didn't check the other link I posted earlier ( which shows videos with lens cap on and lens cap off ):

http://www.cameratown.com/reviews/canon5dMKIII/light_leak.cfm

Take some time to analyze. This is an issue, not big, but issue anyway.

NO camera that shifts exposure when turning LCD backlight on in dim light (with lens cap OFF) can be called as "in normal behavior" or "non-issue"...

I've seen that.

When I get ONE SINGLE ruined image due to it, I'll consider it an issue.

As some have pointed out, other EOS cameras show similar behaviour, and the sky didn't fall then either.
