Well Boris, I really like my MTO 500. Bough it in 1982. A few years back I had good deal (actually in Belgrade) on reflex Nikkor 8/500 (Ai vintage) , bought it, tested and sold it. MTO was better, tad slower, but produced nicer pictures. With 800asa on nice sunny day you are fine handholding it. For MTO 1100mm you need good tripod, even on sunny day.
