If instead you look at large print sizes or 100% crops, I find that much shorter durations are needed, like 1/32+ to get critical sharpness for 100% crops of a 21 MP sensor. I think it would be easier to get 1/32 down to 1/4 with VR than to get 1/4 down to 1 second. I don't know what it is, exactly. Hopefully I'll get to try one out.
