Just tried mine under some direct light in the kitchen (25600, 30sec).

First test was with a body cap on. The result was a fairly uniform red frame.

Second was same setup in a dark room, to see whether light leak was the cause. Sure enough, this was dark grey instead of red.

Third was back under the lights with the kit zoom and its lens cap and hood. That was uniform almost black.

Last test was with a Fotasy Canon FD adapter and an nFD 35/2 with its cap on. This resulted in an almost black screen with a bit of a dim red streak in one corner. I guess the adapter does leak. It should be noted that the E-mount end of the adapter has thinner parts, especially the bayonet and tube wall, than the native kit zoom's mount.

A7 with kit lens and a number of legacy lenses (mostly Canon FD)

I also tested first with the cap "untaped", more leak so i taped the whole thing with plastic foil under to avoid a sticky lens:) no adapter used. I dont like this! The lenses are weather sealed but not the mount is not light sealed, sigh....

Photography for me is not about recreating what i saw through
the viewfinder but to show people the way i want to see the world
