4x5 Auto Graflex Lens question

[DeanChoochLandry]

Hello All. I'm new here.
My primary camera is a speed Graphic wit han Aero Ektar lens but I recently acquired an 4x5 Auto GraflexRB and I love shooting with it. However, the 2 lenses I have, a 5x7 Bausch and Lomb Zeiss Tessar 1C 4.5 and a Carl Zeiss Jela NR 18cm 4.5 will only allow me focus up to 5' away and no further. If anyone might have a recommendation for a really fast lens that I'd be able to focus to infinity and do portraits I'm all ears. Thank you in advance for any help.

The bible, first edition, says that the 4x5 Auto Graflex RB was offered with lenses with focal lengths of 9" to 24". There's a very strong hint. Your lenses are too short. I'd go for a 10" lens, this should allow reasonably close focusing and make infinity. Don't get a telephoto.

Thank you very much Dan.

The 8" f/2.9 Pentac should fit the bill. At least it will on a 4x5 RB SuperD, not sure if the flange-focal distance is longer on the Auto Graflex or not.
