thanks for looking. I recently bought a D70 and am wondering why when I mount my Tok 400 5.6 atx the aperture seems fixed on f6 when using the program setting. No manual available. Apertute is locked in on the lens at f32 as prescribed. Aperture will change in the camera when using other shooting modes. Is it purposely designed to do so in order to achieve higher shutter speeds with a tele?
Thanks for any help.
