Schneider Optics G Claron 305mm f/9

Just maybe the perfect field lens. It can be used as a normal lens for 8x10 (my use) or as a telephoto lens for 4x5. It's excellent as a macro lens and makes a fabulous enlarger lens. The 67mm filter size means you can use filters from other systems with a stepup ring (72). I use 67mm filters from my Pentax 645 system and 72mm filters from my Canon system. The large image circle in use surprised me. Schneider quality is a given. This lens is a best buy.

Compact, large image circle, very sharp, and versatile.

None.

None

This is just a perfect field lens, its size, weight and general handling is ideal for use as a telephoto on 4x5, and the best part is that there is image circle that you will never get to use!
Optical performance is typical Schneider, - first class. A highly recommended lens.

Compact size, large image circle, APO performance in the close focussing range, excellent performance as an all round lens.
Perfect for field work.

None, even focussing is no problem in an outdoor situation. have never used it indoors.
