Very fast even with the 20mm.

The question is whether fast moving objects will be distorted because of rolling shutter when using shutter speed faster than 1/500s.

Also, looks like there is no benefit in small camera size when using anything but kit lens.

WRONG - With the mechanical shutter speed of 1/500th sec will cover all lenses up to 250mm focal length (effective 500mm) so just fine for the teles designed for it. Just how often will you really need a faster shutter speed - rarely except in very bright situations where electronic shutter fine if excluding very fast movement. While I might use 1/1000 sec for very fast action if available. based on data from pictures 1/500th sec fine for medium tele range and lower ISO.

So, you are saying that at bright sunlight GM1 users will be limited to F8 aperture if they are going to shoot something that moves? And heck with diffraction or DOF, F8 must be OK because "F8 and be there", right?

As for alternative, I also imagine convenience of using ND filter to keep shutter below 1/500s. "Princess, please stop for a moment, daddy has to put ND filter on camera".

Oh, and one has to remember to switch between forcing mechanical shutter and using electronic shutter because electronic is certainty fine for something static, but not so much for motion. How would that even work?
