Originally posted by stevebrot I shoot my FA 35/2 on FF regularly with no problems with light leaks. I am, however, mounting it to native K-mount bodies without the all-too-common hazards of the various E mount adapters. (Do they all have light leaks or is that just a common forum topic?)
different lens on the same adapter isn't nearly as bad... i'm wondering if it's somehow leaking in front of the aperture ring, because the rubber band isn't fixing all of the problem.
have you ever tested anything for light leaks? because a number of camera bodies leak at the mount, not just the a7/a7r... sony provides a free warranty fix for the body light leakage issue.
the k3/k5 is supposed to be fully sealed, so perhaps you could test the fa35 for leakage... max iso, 30 second exposure, with bright sunlight pointed into the side of the lens, at the mount area.

The Canon 5D Mark III and Nikon D800E DSLRs with light leak cost even more.
"And for you Fanboys who just can’t wait to Sony bash over this odd little issue, let he whose camera is without light leak cast the first stone. Because, so far the same problem has been found with Canon, Nikon, and Fuji cameras. I assume a similar solution will work just fine for those, too."

that makes sense, because the difference between 28mm vs. 24mm is significant on full-frame... and it's more than just a width issue.
