New Sigma HSM Lenses Get Official [Sigma Hit Out With New 50-500mm & 70-200mm Stabilised Lenses - Canon, Nikon, Sony, Sigma and Pentax Fits]
this year’s PMA event but of particular interest to me is their unveiling of their new 50-500mm F4.5-6.3 DG OS HSM and 70-200mm F2.8 EX DG OS HSM lenses – both of which sport Sigma’s optical stabilisation technology (which, in the case of the former, is sure to get the pulses racing of those looking to shoot distant wildlife as well as events such as airshows).

The new Sigma APO 50-500mm F4.5-6.3 DG OS HSM ultra telephoto zoom lens, which comes, as mentioned above, complete with Sigma’s optical stabilisation (offering a purported four stops benefit) – something warmly welcomed on a lens offering this kind of reach – consists of four SLD (Special Low Dispersion) glass elements serving to reduce lens flare and ghosting across its entire focal range and utilises Sigma’s Hyper Sonic Motor to allow for high speed, quiet focusing.

Sigma APO 50-500mm F4.5-6.3 DG OS HSM Specification:
- Lens Construction:22 Elements in 16 Groups
- Maximum Magnification:1:3.1 (f=200mm)
- Angle of View:46.8-5.0 degrees

The new Sigma APO 70-200mm F2.8 EX DG OS HSM lens will also prove to be a potential winner (assuming image quality is good) thanks to offering an impressive maximum aperture of F2.8 throughout the entire zoom range whilst offering 2 FLD (“F” Low Dispersion) glass elements (said to offer the same performance as fluorite glass) whilst you can also factor in optical stabilisation (like the above lens purported to offer four stops benefit) whilst the minimum focusing distance comes in at 140cm (55.1”).

At present we’re unable to ascertain pricing of either lenses but the moment we gain these details we’ll update this post asap (not least because I have my eye on the 50-500mm – just don’t tell the wife).
