<strong>A light leak? Really?


</strong>A light leak issue in the 5D Mark III has been reported over the last couple of days. It seems the top side LCD may be to blame. I can confirm this is happening on at least one of the 5D Mark III’s I own (the rest are out for rent), I will look into the issue with more bodies in the coming days.</p>
<p><strong>Simple Test Procedure

</strong></p>

<ol>
<li>Put your body cap on the camera body.</li>
<li>Put the viewfinder cover that came with the camera over the viewfinder.</li>
<li>Set the camera ISO to 800 and put the camera in “P” mode.</li>
<li>Turn on the backlight for the LCD panel and watch the exposure change</li>
</ol>
<p>Below is a video showing the issue.</p>

<p><strong>Other light sources cause the issue?


</strong>Yes, shining a flashlight on the top LCD causes the exposure to change, as does sunlight and bright overhead lights. All of which happen with the body cap on.</p>
<p><strong>Does this matter in the real world?


</strong>For the moment, I’m not sure. I haven’t noticed any issues with metering on the 2000 or so shots I’ve put through the 5D Mark III. I’m sure we’ll know more in the coming days.</p>
