From the period in SLR development that revolved around the amount of automation that could be included. Quite unique in design in that programmable scene modes could be obtained by inserting micro chip cards. Without the chip this runs as Program automatic or shutter priority. This one includes chips for manual and sports modes. I know I'm probably biased but I love the handling of this camera, so much like my 500si. The disappointment is that the standard Minolta kit lens is not the sharpest lens in the bag. There is also a Sigma 70 - 210 with the camera and this is sharper but, of course limited in use.
