As you may have noticed on this net, screw lenses can be pretty decent. The enlarger can also be a good way to check the sharpness of the lens itself since you can see more than one aperture setting easily when you look at a negative with a grain focuser. But then there are always TEST CHARTS :^) I suspect that apertures smaller than f2.8 are not used on enlarging lenses because these are flat field lenses used in a controlled lighting situation. Anyone else have insights on this? Best Regards, Mark Eastman meastman@adobe.com Replied: 17 Aug 92 08:50
