If it has an A position on the aperture ring it will work fine. If not it will not meter on the istD. However, going by apparent experiences of others at GFM it may auto adjust the ASA enough to give you proper exposures if you set it anywhere close to the correct aperture and f-stop (no guarantees on this though).
