Olympus IS-10 brand_Pixco The Mamiya C3 Professional isThe Olympus IS 10 is an automatic, fixed lens SLR camera with a 28 110mm f4. 5 5. 6 zoom lens and some light manual capability not much, but more than you'd find on a pure point and shoot. The SLR structure means that this camera isn't exactly pocketable, but you do get true through the lens viewing and spotmetering, which is a pleasant surprise. In very good cosmetic condition, with minor wear.
