Re: A7/A7R Light leaks reported + White Orbs issue?

I repeated the test without a lens and the body cap on. 26500 ISO  30 second exposure LED headlamp at 3inches from the flange red junction. I go a leak again but a different pattern. I will talk to SONY support tomorrow. What if anything is happening ?

If the light was leaking through the mount, then wouldn't your second shot be identical to the first?

As both shots came out very differently, it seems to me that the first was light leaking through the lens cap and second was light leaking through the body cap.

I'm quite puzzled why people seem to think the e-mount lens caps are an effective way to keep out 100% of the light when conducting these tests - they are designed to protect the front of the lens when it is not in use, but they are not designed as a light seal.
