These sensors are a fraction of the size of minox film never mind 35mm, depth of field effects we are used to are impossible on them. It is surprising how good the enlargements are from such tiny "negatives" but if you want 35mm type DOF you will need a 35mm size sensor - very expensive at present, thought the "in betweens" (Nikon, Fuji and most Canon digi SLRs and Leica in a year or so) are an excellent compromise IME. cheers Frank On Wednesday, November 19, 2003, at 08:25 pm, Peter Dzwig wrote: > Looks like what I want, but I still want head-up info - and PLEASE can > we have a minimum stop smaller than f11. > > Peter Dzwig > > <big snip> - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
