I was given a circa 1905 Korona 8 x 10 view camera. The bellows had been replaced in the 1980's and everything else works great. I want to replace the original Wollensak lens with a modern lens as it is expensive to purchase and develop these 8 x 10 color transparencies (but they are gorgeous!). The lens board has a 2-1/2 inch mounting ring attached to it, and the Wollensak lens\shutter just screws into it. I am guessing that the threads on the mounting ring are fine or extra fine because there are about 4 threads per 1/4 inch (about 16 threads per inch).
Can anyone recommend a relatively modern lens for less than $500 (probably used) that will fit the 2-1/2 inch mounting ring?
