Range of focal lengths for an RB Auto

[brian d]

What jon said, I have a 3x4 RB auto waiting to be fixed up. I tried a 162 enlarging lens on it and it wouldnt quite focus to infinity

I've tried a 127m/f4.7 Ektar on my non-auto Series D 3x4 graflex. As I recall, it had a limited focus range of about 1 to 4 feet.

15 inches sounds interesting.

i finally got a chance to fake a lensboard
and stick a 10" and a 15" tele raptar on my series D ( 4x5 )
the 15" works fine, i had it on a speed graphic lensboard
not even as far back as it needed to be ( the placement with
the series d lensboard ) ... it focused at infinity and was nice
at close and medium distances ... the 10" ... well, it needs the equiv.
of a recessed lensboard to focus at infinity, but it would be fine for
portraits and non -infinity photographs.

Jon,

I use a 4x5 auto graflex often (great camera) with a 10 inch Raptar most often. It came with somethiing around an 8 inch which does reach infinity. The 15 inch tela-raptar is nice for close headshots. For the softer older style I have a 10 inch Veritar and an 8 3/4" verito that give interesting results. Fun.
As I'm sure you know, the camera was intended to be hand held, but I've found the recoil from the mirror slap is enough to effect sharpness. I heavy tripod fixes the problem, but to keep it portable I use it with a monopod, when out and about. It give enough support to prevent the camera from "jumping" when the shutter is released.
