You might do some tests: Shoot the same scene at different apertures using a sturdy tripod. Use slide film to be able to compare the shots in, let's say, 1.8m 1.2m (50 times enlargement) or even 100 times. Pick scenery with lots of detail. You can cut the slides in halves and mount two comparable shots in one frame and then view the slides from a distance using binoculars. That's how I tested the Pentax SMC-FA 28-80/3,5-4,7 against the Tokina ATX Pro II 2.6-2.8/28-70mm. The latter was clearly sharper in this enlargement, which BTW is confirmed by tests made by Photodo. In small enlergements it's not posible to clearly see the difference. (That's how they get away with selling poor lenses, I guess - it's difficult to tell the difference from a 4x6" print of a summer holliday shot!
What matters to me, are shots made under difficult circumstances, where I have to push the limits of what is actually possible. That's when a good lens makes the difference - weather I get a usable photograph or not!

I got it with a used SFX wonder, whether I should start using it instead of the Pentax SMC F 35-125 3.5-4.5. I did not quiet understand which F 70-210mm zoom you liked/disliked, was there a typo in your posting? -----Original Message----- From: Jens Bladt [mailto:[EMAIL PROTECTED] >>2.
