I have a question. I am new to the Df and using non-ai lenses.
I get highly overexposed pictures when using apertures 4 and 5.6 on my 55mm f1.2 non-ai (the exception is aperture 1.2). I am planning on returning the lenses, and the seller said I could only use non-ai lenses on the Df with an aperture of 5.6 or faster (is this true?). With my 135Q, I do not have overexposure pictures if I use an aperture of 4 or 5.6. Am I doing something wrong?
