A new Stock of lenses will finally ship out on February 20 according to BHphoto. And exactly one week after Sigma might announce the new 70-200mm f/2.8 FE :)
Photographyblog just posted the Sigma lens review and concluded:
In terms of its optical performance, it’s tack-sharp in the centre throughout all of the zoom range, with sharpness only falling off a little at f/2.8 at the very edges of the frame. It also produces some very nice bokeh effects thanks to the 11-blade iris diaphragm.
There’s some vignetting at wide-open apertures, barrel distortion at 24mm and slight pincushioning at 70mm, but all of this can be corrected either in-camera or during post-processing.
Auto-focusing proved to be very quick on the Sony Alpha A7 III that we tested the lens with, and manual focus over-ride at any time is a great feature.
Overall, the new Sigma 24-70mm f2.8 DG DN Art is a very well-built, very fast standard zoom lens that delivers superb image quality at a frankly unbelievable price, and is therefore a more than worth winner of our highest award.
