    Re: Which are the fancy lenses??

    I'm guessing that 80mm you're talkiing about is a Schneider 80mm f/4.5 Super-Symmar XL. It's a newer and more complex design than the other 75's and 90's you're seeing, among other things.

    Good advice!
  3. Re: Best 75mm / 90mm lens?......totally kidding, but not really...read on pls

    The biggest difference in 75's and 90's is coverage.

    For the most part the larger aperture ones have larger coverage for movements than the slower ones.

    I think the f/4.5's incredible, but...

    f/16, not f/22. Schneider's data is for f/16. And in this case, Schneider is the proverbial "horse's mouth."

    Also, modular transfer function improves as you stop down across the frame, so IC...

    Re: Preferences for 150-165mm lenses in 8x10?

    The Angulon 165's IC is 300mm at f/16. I have a late one in a Compur Electric #3. It makes a nice moderate wide on 5x7 with lots of room for movement, but it will cover 8x10 at f/22. There is no hard...

    For what its worth, the 300mm W with inside lettering may get a listing of 420mm IC, but it also gets a angle of view for coverage 80 vs. the 70 of the 300mm W with writing on the outside ring.
