So here’s the deal, Sony admits there is a problem and most of us have seen examples of the problem, yet I still think everybody is overreacting.
If you haven’t heard, in simple terms, the lenses aren’t sealing well enough onto the mount of the Sony a7/a7r and under ridiculous (yes ridiculous) conditions will show that there is light leaking into your photo through the mount. Here is an example of such leakage …
This is where it gets ridiculous and I think most people are being picky. Yes the leak is pretty bad, yes a camera in the class of the Sony a7/a7R should not have these issues and yes nobody paid $2000 for this. The photo above was achieved with these settings: ISO 25600, 20secs exposure. On top of that the presence of a bright light source (flash, sun etc) needs to be in the area.
Let me just give you all a few minutes to let that sink in. Think back on your photographic journey and tell me about the last time you took a LONG exposure photo at ISO 25600 under bright conditions. Let me guess, you can’t? Neither can I, I do stupid shit with my camera just because I feel like it and I cannot find an example where I have personally used those settings (or anything along those lines). I have done 90sec exposures at ISO 100 in moderate lighting, 3min exposures at ISO 400 in the dark but nothing like the type of exposure required to bring out this light leak.
Anyway it’s not like this issue doesn’t happen in other cameras either, have a quick scroll through this site bringing up leaks in various DSLR’s. So if you were thinking about buying a Sony a7 or a7R and this light leak issue is putting you off … don’t be that guy, nobody likes that guy, especially if you’re a hipster wannabe who adds light leaks to your instagram photos because clean images are too mainstream.
P.S. Yes I acknowledge there are some of you who do encounter this problem in your field of work, my advice to you is to bring a DSLR.
