Overview

The Samyang Reflex 300mm F6.3 is a compact, lightweight mirror lens offering good value for budget-conscious photographers wanting super-telephoto reach. Its fixed f/6.3 aperture is slow, limiting use to bright conditions. Optical strengths include no chromatic aberration and good sharpness at corners, though center sharpness may be softer. Weaknesses include unique doughnut-shaped bokeh and desaturated images. Build is sturdy with a large manual focus ring, but focusing is delicate. It suits photographers willing to work with manual focus and fixed aperture for sports, wildlife, or candid portraits.
