I have an old pre-set 3.5 200mm Tak pre-set, and they aren't as much of a PIA
to use as one might think. Once you set the exposure, you either leave the
lens stopped down, or if you open the aperture, you gotta remember to stop it
down just before you shoot. I haven't forgotten to do that yet!
It's such a crisp lens, that the results I've gotten from it are worth the
extra effort.
regards,
frank
