    Overview

    The Soligor AF Zoom 100-400 mm f/4.5-6.7 MC is a budget telephoto zoom for Canon EF mount, often sold under various brands. Optically, it is sharpest at 100-200mm and f/8, but sharpness and contrast degrade at longer focal lengths, especially at 400mm. Build quality is reasonable with a plastic body and metal mount, but it is fragile and prone to damage. The push-pull zoom design is preferred by some for quick framing. It suits budget-conscious birders or wildlife photographers who can stop down and use good light, but it is no substitute for premium lenses like the Canon 100-400 L.
