Howdy,

I take it that size matters :>). From what I dug up 135mm is good to print 4x5, does that mean that I should be looking for
XXXmm to do 5x7 ? I'm coming up with 150/180/210 and not sure which one to choose ? Also, what are the characteristics of Companon-S, vs
Nikkor EL, Rodenstock ? I'm presuming that all of these are good.

Anyhoo, any helpful hints would be appreciated.

Les
