Practical Photography
’The Sigma 24-70mm f/2.8 is made from top grade glass consisting of ELD, LD and Aspherical lenses. All this glass weighs in at a solid 790g, but the resulting performance is worth it.’ ‘…you’re getting a high performance lens that reduces distortion, flare and aberration that could ruin a great shot. The extra quality of this 24-70mm EX DG lens is demonstrated by sharper edge definition and cleaner images. Focusing is fast and quiet too, thanks to the HSM technology.’
   
British Journal of Photography
’The Sigma seems comparable to the current Canon wide open… and sharper centrally than the Nikkor. The extra sharpness over the APS-C area at f/2.8 is good news as many of these lenses will be used on APS-C cameras to take advantage of f/2.8 central AF sensor accuracy. The HSM focusing is a great improvement over earlier models, and is just as smooth and silent as the branded equivalents, with similar manual override options. Colour transmission, contrast and the look of the image are hard to fault. Resistance to flare is good. Good sharpness counts more than smooth bokeh, and it’s certainly got that.’
   
Master Photo>Digital
’It’s strikingly sharp centrally and has good even coverage at 70mm. The HSM focusing is a big improvement over the body drive or micromotors. This is of course the main selling point of the lens, apart from the compact dimensions and reasonable 915g weight. It does not extend when focused and only a modest amount when zoomed. If you want am ultrasonic focusing 24-70mm f/2.8 at around half the price of your own brand, this is your only option.’
   
Amateur Photographer
’The build quality, as the EX suffix suggests, is high. As a unit it feels sturdy, with the metal construction of the optical components housed in an engineering-grade plastic casing. Sigma products make use of the latest optical media and accordingly this lens has two aspheric-surfaced elements, one in extra low and two in super low dispersion glass. The data panels exhibit a fine performance of professional quality. Definition of fine detail is high enough to match that of the top DSLRs.’
