|Introduction | One of the sharpest long telephoto zoom on D800 | Sigma APO 50-500mm f/4.5-6.3 DG OS HSM Nikon performance | Sigma 50-500mm F4.5-6.3 APO DG OS HSM Nikon Versus Nikon AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR | Conclusion|
Sigma’s range of telephoto zooms can put the premium marques to shame in terms of choice, and this one is not only hugely versatile but can boast stabilization and a ultrasonic type motor while also saving a considerable sum. But, just how well does it compare with the new Nikon 80-400mm VR? Read on to find out.
With more choice than either Canon or Nikon can currently offer, Sigma has an enviable range of telephoto zooms. Given the wider zoom range and a $1,659 price tag that comfortably undercuts the Nikon and Canon 80/100-400mm f/4.5-5.6 equivalents, this one sounds particularly tempting. Not only does this full frame lens boast an ultrasonic type (HSM) AF motor but it also has optical image stabilization, which Sigma claims allows shutter speeds of up to 4 stops slower than a non-stabilized model and a useful close focus capability of 1:3.1 set at 200mm. While the large 95mm filter size is rather restrictive price-wise (with polarizers especially), the optical construction is impressive with four low dispersion glass elements out of a total of 22 in 16 groups. Measuring 104.4x219mm and weighing 1,970g this lens is compact if somewhat weighty suitable for both full-frame and APS-C type (DX) DSLRs where on the latter it’s the equivalent of a 75-750mm.
