You can test it yourself, can't you? If it's manual focus I assume it has an aperture ring (correct me if i'm wrong). What happens if you turn that ring from 7,2 to 8 in Av mode? Does the shutter speed change to reflect this? What happens if you take a picture in metered manual mode at 7,2 and 8 with the same shutter speed? Any difference in the resulting exposure? Or am I missing something? I don't know the lens at all- but that was clear by now I think ;-) Regards, Lucas -- GMX DSL = Maximale Leistung zum minimalen Preis! 2000 MB nur 2,99, Flatrate ab 4,99 Euro/Monat: http://www.gmx.net/de/go/dsl
