CDMMA, I'm an amateur photographer myself, all film, 35, 120 and 4x5, Nikon, Leica, Rollei, Schneider and Rodenstock. The optical quality of scopes is nowhere near what you may be used to. Often poor resolution seems to be hidden behind high contrast. Just about anything will work at 100yds for hunting, but for precision shooting or longer ranges almost everything in the cheap seats is disappointing. I recently purchased a Mueller APT and have been impressed for the low price. My sample has good resolution, clarity and reasonable contrast. The adjustments are repeatable and the ability to focus the objective is a bonus.
