    Overview

    The MTO-11 1000mm f/10 is a compact mirror lens with good central sharpness but soft corners and low contrast, according to OpticalLimits. Build quality is solid with a smooth focus ring, but handling is tricky due to narrow depth of field and fixed f/10 aperture. It suits photographers wanting extreme reach on a budget, though chromatic aberration and flare are issues (OpticalLimits). Best for static subjects in good light.
