I was wondering if anybody had a good resourse for geting screw mount lenses. They just arn't that avalible.

There's plenty available.
B&H Photo Video usually have some in their used dept. and so will Adorama. You can also get them at KEH.com.
Online auction sites might be other places you could check too.
Good luck.

and some newer ones and very nice ones from Cosina Japan.

And if you're really picky about your glass, Carl Zeiss offers a few choices in their ZS (Zeiss Screw) mount.
