So I bought this baby and I do want to shoot with my 4x5 cameras. Mostly I shoot 6x6 though. This lens on the enlarger is 150mm f 5.6 That should be good for 20x24 prints from the 6x6 film right ? To be honest I am a little intimidated by this machine but I am in the process of building a darkroom right now and will need to be learning how to set it up and use it in a couple of months. Scares me
