Sigma's stabilised 70-200mm for Nikon — the OS version with APO correction.
The Sigma 70-200mm f/2.8 EX APO DG OS HSM for Nikon F is the stabilised version of Sigma's constant f/2.8 telephoto described across earlier IDs. Adding OS optical stabilisation addresses the main weakness of non-OS versions. APO elements control CA. HSM for quiet AF. The OS + APO + HSM combination creates a competitive alternative to Nikon's VR II.
Good sharpness from f/2.8 throughout. OS provides approximately 4 stops of stabilisation — a significant practical advantage. APO controls chromatic aberration. HSM motor fast and quiet. Constant f/2.8 for consistent exposure. The OS version is dramatically more practical than non-OS alternatives. Tripod collar included.
Nikon F mount. Filter thread 77mm. Weight approximately 1,430 grams. Build quality professional EX. OS is the critical addition over non-OS versions. Tripod collar. The Sigma 70-200mm f/2.8 Sports is the improved successor. This OS version represents good value between non-OS budget and Sports premium.
Available at reasonable prices. Check OS motor and AF. The OS addition makes this dramatically more practical than non-OS versions. A good mid-range 70-200mm f/2.8 for Nikon. The Sports version is the upgrade. Better value than non-OS versions at only moderate price increase.
