The longest lens I have for my Horseman VHR is a Horseman 105. I'd like to find something in the 200 mm range that is sharp but not too expensive. I found a Horseman 180 with a lensboard. However, maybe I'm better off looking for a 210mm copal lens (size 1). I'd consider something from Nikon, Fuji, or Rodenstock. Would you go with the horseman or look for something that might perform a bit better. I imagine the difference between 180 and 210 is negligable. BTW I use my Horseman with a 6x9 back.
