If you're in the market for a very wide angle zoom, this one is certainly worth considering.While there is distortion, that's to be expected with this type lens. The images it produces are, in a word, sharp.Its maximum f-stop tends to make shooting dim interiors difficult without a support

Consistent Output; Easily Interchangeable; Lightweight

Poor in Low Light

I love the Tokina 11-16mm... Recently got a D800... So was investigating options. Tried the 12-24mm Sigma version II... I prefer the corner sharpness and image usability in the 8-16 shoot DX on the D800 over shooting the 12-24 FX on the D800... The 12-24 is going back to Adorama...

Wide, so very wide; Price is so very reasonable, Sharp, pretty sharp

Not FX ..; But good enough in DX even on FX

I was lacking a really short lens for Landscape ..... fisheyes don't hold it for me but a really short,sharp lens with good control of barreling does. This is probably the only lens out there that has all the above features in spades .....

This is a great lens and exceeded my expectations. It is V E R Y wide!

Durable; Easily Interchangeable; Fast / accurate auto-focus; Strong Construction

Heavy

I use it for almost everything. I love the depth of field. so far nothing I don't like about this lens

The Sigma 8-16mm F4.5-5.6 DS HSM ($1,100 list) is a lens that either speaks directly to your soul or you find nearly impossible to use effectively. It's available for Sigma, Canon, Nikon, Sony/Minolta, and Pentax APS-C cameras , where it produces a field of view equivalent to 12-24mm in classic 35mm...

Very, very wide; One-of-a-kind lens

Extreme distortion on the wide end; Relatively slow aperture; Softer at wide angles

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.

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

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...

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.
