Shutter

Anybody know what's wrong with this?  Sony a7ii with Leica 90mm Summicron r.  ASA was set to 800.  f stop was about 11.  Resulting shutter speed was 1/6000 sec.  Slower shutter speeds don't show this effect, but all of them at this speed did.

Looks as though the second curtain is speeding up towards the end of its travel (I assume it is a vertical travel shutter) so the slot is getting smaller and exposure is reducing.

Happens to me too with Nex7, especially when shooting vertical with wide angles. Have you tries vertical?

Is EFCS on or off? I would try it with EFCS off if you have it on.

I agree with 'dbmiller'. That is definitely a shutter timing issue and I would think it's the EFCS having an effect.
