My favorite of all time was my Konica T which I sold to buy a Nikon F becasue I need a motor drive. Great lens, strong, great meter. My current fav is my Sigma SA 9, has lot of features like mirror lock up, spot and matrix metering, light weight and has a shutter speed dial, auto focus is not very good but I usally manual focus. I also really liked my Nikon F2 with drive.
