I was LOANED A TAMRON Adaptall 2 17mm f3.5 lens Nikon fit by a Camera Club member so I used a Nikon FG that my Wife never uses now. It has built-in Filters so I used the Yellow one on some shots.St Thomas Church.
I had one of those Tamron lenses, exact same model, probably around 40 years ago. Only way I could afford such a wide angle lens. Very good in B&W but there were issues with colour with one of the colours not being in as good a register with the other two colours, so with backlit subjects some of the colour spectrum was a bit interesting.
