Does your camera have an AA filter, if so what amount of blur does it apply?
There is a vast difference between f2 on a 100mm lens FF ... than there is of 3.2 on a 25mm lens on a 2/3.
Despite the concept of effective focal length ... the fact remains that you were hand holding a 25mm lens @ 3 times the shutter speed of the FL. Thrice was handholding at appx 1:1 (1/80).
