I just got an A6000 and the SEL 35 1.8 lens. On some shots I occasionally see a very subtle ripple effect. I don't think it's caused by rolling shutter and sensor readout speed, it seems like it's optical to me. I say this because I haven't noticed rolling shutter when shooting with un-stabilised lenses. I had the optical steady shot on, and I wonder whether this is the culprit. I'll try to post a clip later, but I wondered whether anyone has had similar experiences either with this lens or other Sony OSS lenses?
