I found a print in my files taken at Birling Gap, East Sussex (UK) where I had used the minimum f22 on my 28mm f2.8 SMC Pentax-M lens and on a 16x12" print it is not really 'Sharp' anywhere, probably due to 'diffraction'. I used an ME Super, Grad Grey Cokin Filter, tripod and that Kodak 400 ASA C41 B&W film which I processed myself -- maybe the FILM is not very sharp either . It LOOKS SHARP on THIS size photo .
