I've officially been a LF photographer for about 36 hours now. It's amazing what $300 burning a hole in one's pocket at flea market will do. Anyhow, I purchased a 5x7 Press Graflex with a Wollensak Series II f4.5 9.5in. Everything seems to be in working order and I've figured out how it operates. The camera came with two film holders, a standard two sided holder and a Graflex Film Pack Adapter. I would like to purchase some more of the standard two sided holders, but I see many entries about getting the right ones to fit the camera. Will Eastman 5x7's fit the Press Graflex? The pictures on e-bay look the same as mine. I see discussion about grooves on the holders, but neither the camera nor my one holder appear to have any grooves.
Thanks in advance for any help or advice anyone wishes to bestow.
