jbbooks, thank you very much for the detailed reply. Wow! I never expected this. From the small amount of information that I was able to squeeze from the internet I believe your assessment is correct. Formats larger than 8x10 would be pushing it. But, that's okay. I'm fine with 8x10, just not this length of bellows draw. Ouch! Macro I can see will be a tough one. I would think the corner fuzziness you mentioned would vanish nearer f/260. I haven't had a chance to witness your results, but I'll get there soon, I hope. Mine is in barrel form, and I have placed a Packard shutter behind it.

Another application also comes to mind . . . in an 8x10 enlarger configuration. But then again, I've always been a dreamer. Infact I have a whole desk draw full of unrealized dreams.
Fred De Van - Thanks you also. This gives me hope that I'm not wasting my time with this glass. I have nothing else in my arsenal that even comes close.
PS - As I progress with this lens I will try to post an update, and hopefully some personal examples. I'm starting to think that a forum area dedicated to examples from specific lenses would be very beneficial to this site.
