There is a Wikipedia article on rolling shutter effect covers it pretty well. You can also see it on the Q series when using a lens without a leaf shutter, like a K mount lens on a simple adapter. since the Q defaults to an electronic shutter for lenses without leaf shutters. I tried several

I definitely see the point. At 10X the DOF is like, 2-3 µm. Vibrations of just half of that would cause significant blur. Jostein Den 25.09.2017 08:23, skrev David Mann: On Sep 25, 2017, at 12:21 PM, Mark C wrote: Aside from banding the problem with ambient light is

You can also set the K1 to use an electronic shutter in live view mode, no pixel shift. With the camera set to 3 second delay and electronic shutter, you can minimize any kind of shutter shake almost as effectively as using flash and minimizing / eliminating ambient light. But I found that
