Sigma's flagship super-telephoto prime — a professional 500mm f/4 from the Sports line.
The Sigma 500mm f/4 DG OS HSM Sports was released in 2016 as Sigma's flagship super-telephoto prime, part of their acclaimed Sports line. Competing directly against the Canon EF 500mm f/4L IS II and Nikon AF-S 500mm f/4E FL ED VR, it offered comparable professional-grade performance at a significantly lower price, making elite wildlife and sports photography more accessible.
Optical performance is outstanding. Sharpness is exceptional from f/4 and barely improves when stopping down — this lens is genuinely superb wide open. The Sports line optical design with fluorite-equivalent FLD elements controls chromatic aberration brilliantly. OS stabilisation provides approximately 4 stops of correction. HSM autofocus is fast and accurate with customisable focus limiters.
Nikon F mount. Filter thread uses a rear drop-in holder for 46mm filters. Weight is approximately 3,310 grams — heavy but comparable to competitors. Build quality is outstanding with full weather sealing, magnesium alloy barrel, and a carbon fibre reinforced foot. Compatible with Sigma 1.4x and 2x teleconverters. The lens includes a hard case and tripod collar.
Available on the used market at significantly below Canon and Nikon equivalents — the main reason to choose it. Check OS motor, AF accuracy, and lens elements for damage. The weight and size require a serious tripod or gimbal head. An outstanding option for professional wildlife and sports photographers who want 500mm f/4 performance without the full Canon/Nikon price.
