Re: ISO 400 crops - 1/80sec blur

what is odd is the one taken at the lowest ISO (200) is sharper despite having the slowest shutter speed.

This isn't particularly odd - it's analogous to what happens with mirror slap-induced blur on SLRs. You only see blurring across a narrow range of shutter speeds, because the vibration quickly dampens out. So at slower shutter speeds, while the vibration is still occurring, it's across a relatively small proportion of the overall exposure and doesn't visibly affect the image.
