A unique wide angle lens for APS-C cameras providing a rectilinear field of view equivalent to that of a 12-24mm lens on a 35mm camera.

Outstanding sharpness in the centre; Excellent build; Unique wide angle field of view for APS-C cameras; Compact dimensions; Silent focusing; Low distortion

CA towards edges of the frame at 8mm; Falloff at 8mm; No way to attach filters

The Sigma AF 8-16mm f/4.5-5.6 DC HSM may be the new star in this lens segment. It's very sharp across the whole range straight from the max. aperture. Lateral CAs are also very well controlled. That's quite an achievement for such an extreme ultra-wide angle zoom lens.

For the sole purpose of wide angle photography, the Sigma 8-16mm lens is the benchmark. The images are surprisingly sharp. An engineering marvel!

Gary Wolstenholme takes a look at this unique lens, which is currently the widest rectilinear lens available for APS-C sensor cameras.

Never bought a Sigma before, and I had read that some of their wide-angle lenses felt a bit cheap. Pleased to say the 8-16mm looks and feels like the reasonably premium lens that it is. Nice and weighty, smooth focus and zoom rings, and a very snug fit to my A700 a-mount.All lenses are compromises.

Sharp Focus; Strong Construction

Slow Focus

Preface I was looking to a wider addition to my TAMRON SP17-50/2.

Beautiful mechanics; Extremely low distortion

Very poor edge sharpness; Disaster corner sharpness; Vary poor performance against the light

This is an in-depth review of the Sigma 8-16mm f/4.5-f/5.6 DC HSM lens; the model tested had the Pentax-K mount.

I really like extreme lenses. Extremely wide, extremely fast, and extremely long lenses will all allow you to create unique images that stand out from the crowd. When I heard about the Sigma 8-16mm lens I wanted to get my hands on one and start shooting, so I asked my editor if I could borrow one...

Owning a Olympus E5 I have always wanted the Zuiko 7-14mm but the price was just to high. I have recently moved to Sony and picked up this lens for less than half the cost of the 7-14mm. With the crop factor it is actually 2mm wider than the Zuiko. The Sigma is a well made lens.

Build quality; Sharp; nice smooth focus ring; price

Can't use an ND grad; Can flare easily

Lens- specifications landscape or wide a screen sigma 8 -- 16 mm suitable for my needs very hobby , basically get photographed , detail and clean the shooting lens- sigma this . Mugnkin would be much better if diagframa can wider than a series of these . Overall excellent.
