Hi everyone, Arne and Dan,

I read that the lomo RF3 300mm f/10 process lens is a 6/4 double gauss type - does anybody have a diagram of that construction? Is it completely symmetrical? If so I can easily mount it in reverse on my new lens board for landscape work. I have done this with my schneider angulon 120mm f/6.8 with very good results.
