I need some advices from 4 by 5 lens' experts.
I just got an used rodenstock sironar digital 55mm lens, (which I intend to use with P65, sinar 4 by5 camera for wide angle still-life shootings @f 8 or f11) and noticed very thin & short coating scratches on the rear glass center area. such scratches you can expect/ guess when cleaned/ wiped carelessly while some dust still on the glass...
I can see that this lens was kept without the rear lens cap.
They are very thin and short. I can noticed only with LED loupe at the right angle. It's not possible to see the scratches without the loupe. But still they are located in the center area of the rear glass.
I know it's relative. But how much should I worry about the scratches for the image quality? I bought it with a good price. Should I return the lens?
Or the minor coating scratches doesn't affect the quality much?
Let me hear some advices from you guys?
