Anyone else out there with one? Since my experience with the 40mm pancake was a bust (and it is a bit tight on a crop to boot), I am seriously considering one of these. Our local camera store just got them in today.
Dianne whaty body are you shooting with you seem to be getting alot of soft faster aperture lenses, are you sure its not the body? 2 for 2 is highly unusual
no once you AFMA your lens it should be good, narrower apertures increase the depth of field and this may make f4 look sharper because its falling in the in focus area of the depth of field, you always do your AFMA on the lens wide open
