Arriving on these shores in April will be the 120-400mm f/4.5-5.6 DG OS HSM lens from Sigma.
The key feature of this new optic is its Optical Stabiliser system, which offers the equivalent of using a shutter speed approximately 4 stops faster.
In addition, this lens has a HSM (Hyper Sonic Motor) motor and offers full time manual focus.
It is constructed from 21 Elements in 15 Groups, including three SLD (Special Low Dispersion) glass elements, which correct chromatic aberration. The super multi-layer lens coating reduces flare and ghosting.
This lens is also equipped with the rear focus system that minimises fluctuation of aberrations caused by focusing.
The minimum focusing distance is 150cm throughout the entire zoom range and the lens has a maximum magnification of 1:4.2.
The addition of the optical 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 168-560mm F6.3-8 MF ultra-telephoto zoom lens or a 240-800mm F9-11 MF ultra-telephoto zoom lens respectively.
The price for the lens is yet to be confirmed.
