Anyway, if anyone knows anyone interested I'm actually selling a relatively reasonably sized 4x5 Big Bertha right now. I tried offering it to the APUGers at a discount first but now its up on the auction site.
The lens has plenty of coverage for a much larger format than 5x7", but put it on an SLR with a long barrel, and I wouldn't be surprised if there were some mechanical vignetting at wide apertures, just because of the way the mount is constructed. It's not like having a tapered or square bellows with no obstructions between the lens and the film.
What's needed is easy to describe for a straight tube: tube's diameter >= format's diagonal.
A conical tube has to have diameter at rear >= format's diagonal and diameter at front >= lens' exit pupil.
Looks like that's a night game, too, which must have been even more of a challenge.
I think it just looks like a night game because flash was used to light the dim area in the overhang were the photographers were.
I don't know if the cameras would have been practical at all for night games - figure a f5 max aperture, film speed would probably have to be around 6400 to stop any action (and the shutter speed would probably be 1/250th at best. Were those film speeds possible then?
Modern stadium lighting, pro venues included, can range from 1/500th, f2.8 at 3200 to 1/1000th, at 1250, give or take.
Night games were the exception, World Series included.
