Sigma's 'Bigma' for Canon — the 50-500mm covering everything from standard to super-telephoto.
The Sigma 50-500mm f/4-6.3 APO HSM for Canon EF is the Canon mount version of the famous 'Bigma' described in Sony A mount under ID 4108. The extraordinary 50-500mm range covers standard through super-telephoto in a single lens. APO elements control CA. HSM for quiet AF. A unique specification with no competitors.
Same optical characteristics as other Bigma mount versions. Acceptable quality at moderate focal lengths. The 10x zoom ratio involves compromises. APO elements help with CA. The 50-500mm range is genuinely unique — no other lens covers this range. HSM provides fast quiet AF. No image stabilisation on this version.
Canon EF mount. Filter thread 86mm — very large. Weight approximately 1,870 grams — heavy. Build quality solid. Tripod collar included. No IS. The 50-500mm range is the unique selling point — covering from standard to super-telephoto without lens changes. The OS HSM version adds stabilisation.
Available at moderate prices. Check zoom mechanism and AF. The unique 50-500mm range is unmatched. The OS version is preferred for stabilisation. The Canon 100-400mm L is optically better at the telephoto end. Best for photographers wanting maximum range in one lens without concern for optical perfection at extremes.
