I just purchased Conley Anastigmat Series V, 7" (178mm) f/6.3 lens. I am going to fit it to a modern shutter. I am sure the old shutter is not original, someone fitted the cells to it but not quite well becouse the focal lenght seems to be arround 190-195mm. How can I estimate the spacing - distance between the cells to get 178mm focal lenght? Is it easy or rather complicated?
Will appreciate your help.
I have seen a couple of photos made by Jim with Conley Series V, and love the tonality and the image this lens render.
