Graflex Tele-Optar 380mm f5.6 for Graflex R. B. Auto Graflex 4x5

I use a Schneider Symmar 210mm/370mm convertible on my RB Auto Graflex 4x5. The 370mm conversion works fine, I've used it down to 15-20ft. I never tried to see how close I could get with it. I suspect your 380mm Tele-Optar will work fine on the RB Auto. I have a 380 Tele-Optar in shutter that I use on my Graflex Super Graphic. Just as an aside, I've also used the 380 Tele-Optar on my Calumet C1 8x10. It will cover, although movement is minimal.

There are some models of the 15" Tele-Optar which have an extension of the aperture scale so they can be easily set on a Graflex with built-in hood. The regular ones are a bitch to even read, much less set.

Bert at graflex.org built a lens board that moves the lens out from its cave and now it focuses down to about 6 feet.
