Hi, could those lucky ones with a *ist please try this old trick:
- set your *ist to Av - attach a non-A lens - choose a small apperture - unlock the lens an turn it some milimeters, until the aperture closes - the lens should still fit firmly Now: Can you choose another aperture on the lens and does the *ist meter correctly? If this works, it would be a sufficient workaround for me (and probably others interested in the *istD) to use any older lens in aperture priority. Cheers, Heiko
