thanks for any input.

Nikon 180ED. Pentax 67 lenses, I used Canon FD lenses and got an adapter from Moog adapters. I used a Canon FD 85mm lens and I think it was about 55mm. The 85mm was better. Pentax 67 lenses will illuminate even a 16803 chip which is twice the size of STL11.
I would stick with Pentax 67. They are plentiful on Ebay. They also have lots of backfocus. I use a FLI PDF electronic focuser between the cameras's filter wheel and lens. It works well. They have about 85mm of backfocus. Pentax 67 105mm F2.8 has been best so far but the 300mm worked well, the 55mm F4 has aberrations.
