Tried it the other day. Disappointed to find light on the first try. 2nd time use hand to cover the lens cap and found no more traces of light anymore.

I have no leaks at all at 30s ISO 25600, with lens and lens cap attached

Front cap leak perhaps ?
Yeah probably the cap is not tight enough. But then again, I tested with a lens with cap on, there is a slight leak too although not as obvious.

you need to test with actual lenses..no one shoots with a lens cap on...all these iasues could have been avoided if sony had just followed canon and put rubber gaskets on all their weather sealed lenses. The issue is definitely there but in normal shooting you wont even notice..the 5d3 had the same issie but it didnt affect day to day normal shooting
Body cap is not light tight, mount a lens with lens cap in a dark environment .The reported problem has been on dpreview forums since last year for some users. I personally did around 10 repeated tests with the lens cap on in completely dark room and led flash light shinning around the lens mount with the following settings [ 30 s exposure, iso 25600 , F22 ] on my a7r. No signs of light leaks in my images.
If you wanna test, u should shine a flash light or strong light source at the lens mount around 3 o clock position or around the lens mount. Iso 25600, 20-30s exposure, F22 to avoid lens cap issue.
it should be fine if u not getting the images like these[ examples of light leaks], even if you do , i dont think it affects daily shoots anyway.

this light leak thing seem to affect only certain number of cameras...some users including me did not see any after carrying out the tests...imo, a loose lens mount or a lens with poor fit might be the culprit too. A guy i met up with recently had to send in his a7 to fix his lens mount cuz it was loose and all.

Came across this on youtube =) FREE 3rd-party time lapse app for Sony cameras with wifi control including A7/r [Only on Android though] . Video gives a good walk through of the app, works like a intervalometer. Wish they had it on ios too.

Doesnt look like there's any manual controls from the video. Shall try it out tonight. Hopes for bulb mode.
Thanks for sharing!

i think it affects most people. I tested on mine..with a body cap on and when i shine a bright LED directly into the camera, the light leak is very obvious..but that could also be because the cap is not tight and it's after plastic and can still absorb some light going through..
I could not replicate this issue when testing it with an actual lens attached...
There's ONLY a very slight leak with the lens on when i put the lED DIRECTLY into the orange ring...
Having said that..in everyday shooting, this is NEVER gong to be an issue..even with long exposures..you do it becuase it's dark, you're not going to see an actual bright light during long exposures....
And also..when i tested this with the lens on AND lens cap OFF..there's absolutely NO leak because everythign is WHITE! You can only see the leak if it's BLACK...but nobody shoots that way right?
Dude i think u should read through replies before replying. I already mentioned in the the previous reply that body cap's not light tight. The fact u did the test with bodycap on is already an obsolete test. And why would u even do it with lens cap off? Lol? U cant test for light leak if lens cap is off. EVERYTHING IS SUPPOSE TO BE BLACK not WHITE if there is no light leak.And there's a reason why some of them made noise on dpreview cuz some shoot long daylight exposures. Go take a look at whats going on there before posting again. They were testing it in dark cuz It's the best way to test for light leak. you're right that it doesnt affect normal usage but theres still ppl who use it differently. Yours have got a leak, mine doesnt. U see the problem here? Its QC. So thats what the big fuss is about. Ppl unhappy about the variation in Qc bla bla bla.

Yea the current bulb mode is really troublesome to access can only access in M mode and gotta scroll shutter speed all the way below 30 seconds to find "bulb" . Using a cheap Ir remote for it now. Seem to work just fine

i did the repeated test because i just want to make sure i was affected..so to me it's not a redundant test..anyways, leak or not, it doesn't bother me so i shan't dwell deeper into it..
Hello everyone! I'll visit in Singapore during next weekend and want to have A7 kit+FE35/55 +EF Metabones. Do you know what is the price for that combo today in Singapore? Or can someone give information where can I ask offers by mail?
Also intrested price of xt-1..
Thanks in advance!

All iLC cameras are potentially affected cuz of Qc on tolerances on lens mount. 5dmk3, yada yada and other makes all got similar leak "problems". Just seem that sony's problems are always blown outta proportion lol. Haters always gotta hate i suppose. At least sony is aware of the "problem" so im sure affected users might get a fix. Previously 5n's clicky problem gt fixed relatively quickly too.
