    Got this link from dpreview: Do concerns about Sony A7 light leaks hold water?

    Maybe we shouldn't worry too much after all; at least I couldn't bring myself to sending in the camera for it, only to not have it for 6 weeks, with probably a non-conclusive outcome.

    Yeah, if you're really concerned, the simple solution is to get a lens cap strap and slot it round your mount. I haven't noticed a 'leaky' shot on my camera yet so I wouldn't know though :p

    I got a new a7r last week and the mount is extremely rigid, not squishy at all, maybe they have addressed it regardless?

    I did the 30 sec exposure at 25000 and just got sensor noise (a few random speckles, nothing more)

    either way conforting to see it happen with other cameras, not really an issue for me being a portrait person, but I could understand how it would upset someone like Poki who shoots night time landscapes.

    I've yet to test the my A7 using the ISO 25600 & 30 sec exposure. Can't imagine a scenario where I shoot with those parameters. I've used the A7 in bright places including direct sunlight and doesn't seem to have an issue. While I understand that I might run into issues when I do long exposure, I don't want to look for problems that may or may not exist that most likely won't affect me..

    That being said, the lens mount on my A7 is firm.

    Yeah not really a concern for me either. When I did that 30 second high ISO test I only got sensor noise when using the kit lens. Got some crazy light leak when using the hawk helicoid adapter and voigtlander lens. So it seems to be adapter that's causing light leak for mine.

    These articles have me laughing. The online world provides a platform for the creation of mass hysteria for otherwise meaningless events. I saw more about these light leaks than the overall quality of a revolutionary camera in the last month. That's a shame.

    No kidding. When I read that you have to 1) replace your lens with a flimsy, plastic body cap, and 2) expose an image for 30 secs. at ISO 25600 to detect the "problem," my keen mind told me that, whatever "it" was, it wasn't likely to affect me. But that's the Intertubes for ya.

    Seems I didn't do the test right, I didn't shine a torch during the exposure. Literally can't be arsed repeating it though, too busy enjoying the camera as it will never effect me for what I shoot. But I appreciate it's important for some long exposure folk.

    I haven't seen this 'problem' on my A7. I also read Roger's (Lensrentals) blog, which can be quite amusing. I don't normally take photos at ISO 25600 with a 30 sec exposure so I may never know if I should worry. ;)

    My A7R was just returned from Sony - who replaced internal parts in the mount and included a molded rubber cover for the mount/release button for extended exposures. This is what I just posted on the Sony community website:

    I've never seen anyone post an update to the Sony fix (Rubber Mount Shield) and replacing some internal parts under warranty - so I figured I'd let you folks know first.

    Bottom line? With the Sony rubber mount shield and the updates - my A7R has exactly ZERO issues.

    - John

    Attached is what the Sony supplied mount cover looks like...
