Sigma 100-400mm f/5-6.3 DG DN OS Contemporary

Name: 100-400mm f/5-6.3 DG DN OS Contemporary
Brand: Sigma
Availability: InStock

The most accessible professional telephoto zoom for Sony FE — Sigma's 100-400mm f/5-6.3 DG DN OS Contemporary delivers the reach that wildlife and sports photographers need at a fraction of the price of the Sony GM equivalent. Built natively for mirrorless with OS stabilisation, fast HSM autofocus, and weather sealing, it is consistently praised as punching well above its price. On APS-C Sony bodies it delivers a 150–600mm equivalent. The smart choice for photographers building a wildlife kit on a realistic budget.

GearFrame's Take

The best-value telephoto zoom for Sony FE — 400mm reach, OS, and weather sealing for under £800. Punches well above its price at every focal length.

✅ Great For

⚡

Sports & Action 7.0 Strong on focal length, autofocus and weather sealing. HSM tracking handles most sports situations well — the f/6.3 limitation is the only real constraint.

🦅

Wildlife 7.0 Strong on focal length, autofocus and weather sealing. The most affordable way to reach 400mm on Sony FE — OS and weather sealing make it genuinely capable for field wildlife work.

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
