Just starting into shooting a 4x5. Haven't shot any sheet film yet, but have just started shooting with a 6x9 roll film holder that came with the camera set I found. The camera is a Graflex Crown Graphic Special. My question...The camera came with a Schneider Xenar 135/4.7 lens & Synchro Compur-P shutter. I have another lens that I purchased with some other items at another time. It's a Graflex Optar 135/4.7 & Full Synchromatic shutter. Both lenses are equal as far as condition is concerned...But is one better than the other for some reason or another? Also, I have another board for the camera. When I shoot 6x9 with this camera, would I be better off to shoot with a more normal medium format focal length lens for more coverage? Thanks in advance.
