This everyday lens covers a range equivalent to 25.5-105mm on a 35mm camera

Sigma's spectacular first entry in the 'Art series' family of lenses was the fabulous 35mm f/1.4 DG HSM, a lens that took the photographic community by storm. Having now set the bar very high, can the company repeat the success with the (soon to be released) comparatively cheaper and lower spec'd​ 17-70mm F2.8-4.0 DC Macro HSM​? Jack Howard​ writes:

"On APS-C cameras, the lens translates to about a 26-112mm zoom, which is a great everyday range for wide angle shots without significant perspective distortion, to short telephoto for flattering portraits. For the exact focal length equivalence, multiply your camera’s sensor format (1.5 to 1.7) times the focal lengths.

You can see how shallow the depth of field is at F4.0 at 70mm, when close-focusing. Here only a couple of letters in “INTERNATIONAL” are in sharp focus in this detail shot. 1/320 F4 ISO 200 Canon EOS Rebel T3i.

The faster maximum apertures at all focal lengths will also be appreciated by photographers who grab video clips with their HDSLRs. Faster apertures means more light-gathering power for staying at lower ISOs for indoor available light video capture, with less noise in the shadows.
The petal-type lenshood locks firmly in place to help block stray light when there’s really bright point light sources to be dealt with. And the lenshood also features engraved lettering  to let you know it pairs with the 17-70mm F2.8-4.0 lens. This is a really nice touch for any photographer with multiple lenses and lens hoods in a bag!"
