General uses inside and outside. Scenery and people, portraits, etc. Only reason I gave it 4 and not 5 stars is the need to switch off Auto focus, in order to manual focus, unlike Canon USM lenses. Also it stops down to 5.6 sooner than Canon's 18-135.

Comes with Hood; Compact When Retracted; Great zoom range; Light Weight; Quiet

Manual Focus Is Switched; Slower Ap Than Desired

I use this lens on my Sony A 77 II,It has been a pleasant surprise how light and easy to use

Since this is an all rounder lens, don't expect the sharpness of a prime lens. It works good, but care has to be taken to click without chromatic aberration. Not as sharp as Nikkor but that is not gonna be a real issue.

Photographers often have to compromise when it comes to third-party lenses, particularly ones that cover such extreme focal lengths as the 18-250mm. This Sigma model is excellent value for money, offering good sharpness and performance, with a lengthy zoom.

Very lightweight and compact; Pleasing bokeh; Excellent sharpness at the telephoto reach

No manual focus override in AF mode

Sigma's new 18-250mm f/3.5-6.3 DC OS HSM is designed as an all-in-one lens for digital photographers with APS-C-sized (DX) sensors who don't want to carry more than one lens. Covering focal lengths ranging from the 35mm equivalent of 27mm to 375mm with most camera brands (28.8mm to 400mm on Canon...

The WDC Sigma 18-250mm f/3.5-6.3 DC SLD OS HSM lens review discovers whether this is be the best all-round, third-party DSLR superzoom lens on the market.

Effective optical stabilisation

Focusing ring rotates in AF

Sigma's lens was tested here using a Canon EOS 40D, on which it focused reasonably quickly (but not remarkably so) and very reliably. Sadly, but not unusually for a lens of this type, the focusing ring rotates and there is no option to apply adjustments when the lens is set to AF mode.

I use this little gem of a lens whenever I travel. Like all super zooms, it has compromises, but the main one of reduced apertures, is compensated for by the high ISO capability of modern cameras. The longest focal length is also very useful for nature and macro shots.

Light; compact; sharp; fast focus; very usable focal range

No full-time manual focus; though I seldom use this on other lenses

I'm very sorry but this lens is terrible. The sharpness was horrific especially at each end of zooming but macro and extended top 250. Maybe because I'm using a very new Canon (T7i) but this did not produce good images. Perhaps mine got damaged but I kind of doubt that it was broken.

Don 't be afraid to buy this lens !!! I have several Nikon lenses and Tamrons and was skid dish about Sigma. I have had this on my Nikon for several months now and won't take it off. This is a #1 walk around lens. It's ready for anything. There is some weight to it but not too bad.
