Re: Shutter shock

Electronic first curtain *should* take care of most of it. But 500mm at 1/80s? That's not a good example I would say, though IS has gotten better it still works "statistically", there will be a statistical improvement but you can't expect it to work perfect for each and every shot. Which is happening here.

Anyway shutter shock is mostly bound to certain shutter speeds, for older gens MFT it was 1/160 where nearly all of the trouble was. Time and again I would notice a double (ghost) image, check the shutter speed and always find it was close to 1/160. Are you seeing that strong correlation too?

500 mm at 1/80 s is not the most convincing example, but it is one of the few that I kept. It also happens at shorter shutter speeds, and with several lenses. My experiences are similar to those of the OP.

If shutter shock is part of the equation, I don't see why it would affect only the first image of a series.

Keeping the camera and lens still for a few seconds, before taking the first shot, does not help. I see good stabilization in the viewfinder, but when I take the picture I occasionally notice a sudden shift of the viewfinder image, as if the IS system is taken by surprise.
