Subject: Re: Computar dL vs. El-Nikkor?



Hi,

Man, did that bring back some memories. I used some computar's in an early
scanner design. As I remember, they were good designs and very well
documented for MTF and critical points such as nodal point locations and
flange focal distance. If I remember correctly, they were double gauss
designs and they were multi coated (not so common at the time) . I don't
think that you will see any improvement of the El-Nikkor. You really aren't
pushing the performance envelope with the 105 on a 6X6 negative. Both of
these lenses should perform well with that format.

I have some Minolta Enlarging lenses that I have yet to test...they are true
cult lenses. I got them in a pawn shop for 12 dollars for the pair. (50 and
80mm) . These were designed for the minolta color enlarger.
