    75–300mm · f/4.5–5.6

    Overview

    The Sigma AF-APO 75-300 mm f/4.5-5.6 Zoom MC is a budget telephoto zoom with mixed reviews. Optical strengths include acceptable sharpness at 75mm and f/8, but weaknesses include poor sharpness throughout most of the range, high chromatic aberration wide open, and haze issues in some copies (marcusBMG). Build is solid but heavy, with a stiff zoom and sliding barrel design (firtha). It suits users on a tight budget who can tolerate optical compromises, but reviewers recommend the Sigma 70-300 APO Macro instead for better image quality (firtha).
