Any comparisons in quality between Schneider Componon-S 80mm and 100mm lenses? I have the 100mm but want to bring my enlarger head down a bit for enlargements. I am using 6x7 negatives on an Omega D2.

Quality should be equal, but with the 80mm for the 6x7 format you may experience noticable fall off around the edges of your prints. The 80mm would be best suited for 6x4.5. But if you are doing this so that you can make really large prints on your baseboard, there's your trade off.

Schneider doesn't recomend using the 80 mm Componon-S for negatives larger than 6x6. I understand though that the equivalent Rodagon and El-Nikkor lenses are specified for 6x7.

I have an 80 mm Componon-S and do notice a slight deterioration in the corner resolution with one 6x6 neg that has a lot of high contrast detail. If I extrapolate to 6x7 I might expect further deterioration. I don't have any equivalent 6x7 negs to verify this though.

Cheers,

Also note that the 80mm Componon-S is optimized for 8-10X enlargement while the 100mm Componon-S is optimized for 4-6X.

As a matter of interest Ricardo, how do you rate the Schneider Componon-S 100mm for 6x7? E.g. for making 10x8 or slightly bigger prints...?
