> Why bother asking if you've already made up your mind..?
I don't have my mind made up, hence why I am asking. I just can't find any lenses that seem to out perform the digitar.
I agree with the film recorder concept, but only a CSI film recorder can acheive 40 lp/mm on 4x5, the others perform very inferior, and sharpness is of the upmost criteria, hence why re photographing a back lit trannie will provide the sharpest 4x5 film. CSI film recorders have been discontinued for several years, and no parts are made, so not a good long term solution. In addition, this procedure will be done often, so I need a reliable and consistent method. The only 4x5 film recorders made today, CCG, write at 30 lp/mm to the film, which again, is much inferior to what a sharp lens can deliver to film.
