This lens is great for everyday. The f4 provides good light in most situations. The lense has a solid feel and good build quality. Focus has been very good producing clear images.

The 24-105mm f4 OS is Sigma's second full-frame lens in its Art-series which (quote Sigma) "offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision". Blimey.

Excellent all around performer; sharp; good contrast; very pleasing build

weight; not weather sealed

Andy Westlake tests the latest lens in Sigma's Art series – a general-purpose image-stabilised zoom that's designed for use on full-frame DSLRs

Heavy; Zoom opposite direction than Nikon

Sigma continues to expand its impressive line of "Art" lenses, which are characterized by high speed, constant apertures, impressive build quality, and unusually attractive cosmetics.

There is a lens that I miss dearly. It was a Tamron 28-105mm f2.8. It was destroyed in an accident during an event shoot. Not too long after that, Sigma announced their 24-105mm f4 and my interest was captured.

One of their latest products is the Sigma 24-105mm f/4 HSM DG OS | A. As the name implies, it is part of the "Art" series, thus their most prestigious segment of lenses. In Nikon land, it obviously targets the Nikkor AF-S 24-120mm f/4 VR, which so far has been the only real option option for...
