DEAR LIST,
This is for those who REALLY know their optics.
I have a 210 mm Goertz gold dot Dagor and a 210 mm Schneider Apo
lens. I want to do some EXTREME close up photos of dried leaves, seeds, et
alia, on 8X10 to make contact PT/PD (see it IS on topic). I know that both
of these lenses will cover the 8X10 format at this bellows extension and I
am using this focal length to keep from having to stretch my bellow as much
as I would with a longer focal length lens.
**********NOW MY QUESTION: Which of these two lenses would give me better
results in terms of detail and contrast at this magnification (between 5X
and 10X)?
CHEERS!
BOB
