Handling and features This 4.1x zoom lens for APS-C format cameras sports a variable f/2.8-4 maximum aperture, silent focusing, optical stabilisation and a closest focusing distance of 22cm throughout the zoom range.
Since I was very pleased with the Sigma 30mm 1.4 EX and 180mm macro EX, I bought this lens second hand to see if it could replace my good old but dying EF 24-85 3.5-4.5 USM (own Canon 10-22, 70-200L f:4, 100-400L, 400L 5.6, 60 2.8 macro, 18-55 IS kitlens, use also 17-40L and 50 1.4).
fast and correct AF; good image stabilisation; sharp on wide angle at f:2.8; short focus distance
not sharp at f:4 on the long side; big and heavy; yellowish color tone compared to Canons
Daniel Lezano tests and rates the Sigma 17-70mm f/2.8/4 DC Macro OS HSM lens The majority of digital SLRs sold in the UK are supplied in kit form with an 18-55mm zoom, which while representing a good starter lens, isn't the sharpest of optics.
This is very sharp with great colors and contrast lens. Super bokeh. Little bit noisy and not fast but image quality simply superb starting from F2.8.
A compact standard zoom for APS-C digital SLRs with a fast variable aperture, optical stabilisation, a silent focusing motor and an interesting close focus capability.
Excellent optical performance; Decent build quality; Effective optical stabiliser; Close focus ability
Focus ring cannot be disengaged during AF
I bought this lens as a replacement to a Nikon 17-55 F 2.8 damaged irreparably; so consider myself very critical. Features Its a moderately fast 17-70 F2.8 – F4 Variable aperture DX or APS Zoom with Image Stabilisation (OS) and good close focusing ability.
Versatile and useful Zoom Range 17-70; Image stabilization; Fast at wide angle; Smooth bokeh; Close focus
Annoying Manual Focus switch; A touch soft at wide apertures; No weather sealing
Yes, I would recommend this to a friend
Easily Interchangeable; Fast / accurate auto-focus; Nice Bokeh
Heavy
An upgrade of Sigma's digital-only macro lens (the 17–70mm f/2.8–4.5), this large-aperture standard zoom ($450, street) adds a tad more speed, another aspheric element (for a total of three), on-board image stabilization, and several ounces more in weight.
