Antique petzval lens 135mm f3.6 Working tested 5 1/4 inch image circle with some vignette on 4x5 I exclusively used this lens on my Pentax 6x7 with a m65 helicord adapter and a 57mm step down. Sample images provided Doesn’t come with flange 57mm rear thread size Lens is in a satisfactory condition. The focus know has been removed and the interior waterhouse stop flange has been removed in order to widen aperture. I have also included a sample of the lenses coverage on 4x5 I also have listed a large format shutter that fits the front of the lens when the hood is removed.
