Thanks for all the suggestions guys and in the end I bought a Zeiss Ikonta 520/16 6 x 6cm Camera with a 7.5cm f4.5 Carl Zeiss Tessar. It arrived this morning and I must say it is a beautiful little camera which seems in very good condition. I have already loaded it with a roll of FP4 and can’t wait to try it out. Can anyone who is use to using one of these give me any tips? Is it also possible to get a rubber lens hood to fit one of these, so I could fold it back to sit inside the folded camera when not in use?
