I am building a collection of lenses for my 8x10. I once thought my lenses for 4x5 would be useful but NOT. So - I have an acceptable 210WA lens and am trying to score a decent portrait lens. Now I am at a cross roads. I will only be contact printing and I am considering getting some lenses with personality. There must be a point where it is not worth it. I would think at least a sweat spot in the middle would be the minimum required. Otherwise - I can just get a pin hole. So what is a good choice. What is an affordable choice for a modern good lens in the range of 350mm to 480mm?
