Lens Gurus, I'm a newbie to large format, but I'm having great time with the Speed Graphic. I have the opportunity to buy an early (circa 1902) Goerz Berlin Dagor 240mm/f6.8 in beautiful condition, already mounted on a custom made lenscone and Graphic lensboard. The glass is like new. Apparently this lens has really good coverage, enough for 8x10, and I'm planning to use this on a 4x5 Speed and want to be able to use all the movements. Does anyone have any feedback on how this lens might perform? I know it's a double anastigmat, but I don't have any experience with these lenses. I'm most interested in using it for portraiture (both "soft" and "sharp"). TIA, R.J.
