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

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.
