I refer to crippled in the sense that it will not meter with AIS lenses. Meanwhile bodies such as the 2000, 6000, & 8000 series, as well as the F90, F100 and Fm10 among others will meter with them in reduced capability mode. Since all AF lenses have chips in them and obviously the AIS lenses don't, it leads me to believe that it has something to do body. In the N80 if the AF lens isn't set to the minimum aperture the camera displays the "FEE" warning. Do the above mentioned bodies display the same warning with a AIS lens, or is it a custom menu option to use the AIS models? Basically I'm wondering if there is a mechanical nature to this problem or if it is inherent to the thin film board and a selectable option to even use the lens.
