Not outright bad, and for b&w, as JC noted, a yellow or orange filter will make a world of difference. I prefer the converted look for certain subjects, just a matter of taste, I guess. It's in a Synchro Compur, with both aperture scales, forgot to mention that. For any of those that think it matters, it's a Sinar selected lens, looks good on the gg as well as being a decent inexpensive lens. (yes, I'm the one selling it to monkeykoder, btw) Since migrating to Sinar DB or DBM mount lenses, I can't justify having perfectly good, but "politically incorrect" (or unclean, as those of us who can't afford the latest and greatest APO super duper multi thousand dollare lenses prefer to call them) lenses sitting on a shelf when there's a dearth of good quality user lenses out there. Frankly, I'd rather help a few motivated people that couldn't afford it otherwise get involved in LF than make a ton of $$$.
erie
btw, JC, have you tried a 19" Artar on the 12x20? how well does it cover if you have. I've got an extra since being given a RD and was thinking "what's another unusual format that might look good next to the 20x24?" (10x24 is a contender as well)
