I've seen an old Macro Takumar 50 mm f4 screw mount lens and I'm tempted to buy it. It has preset diaphragm with both rings at the front, and a scale showing light loss as magnification increases. I think it goes to 1:1 without tubes. Its condition is near mint. Your advice about this lens will be welcome. Luis __________________________________________________ Do You Yahoo!?
