Overview

The Sony 500mm F8 Reflex is a compact, lightweight (753g) mirror lens with unique autofocus capability, a rarity among reflex designs. It offers good sharpness for its class, though not matching high-end refractive lenses. Weaknesses include fixed f/8 aperture requiring ample light, ring-shaped bokeh from the mirror design, and autofocus limited to the center point. Build quality is solid. It suits budget-conscious wildlife or bird photographers who can work within its limitations, especially on Sony bodies with image stabilization.
