Product Description

This Sigma 12-24mm F4.5-5.6 EX DG Aspherical lens is a result of Sigma's reputation for consistently producing outstanding wide angle and super wide-angle lenses. This lens incorporates an amazing range of popular focal lengths covering angles of view from approximately 85 up to 122 . This kind of scope makes this lens critical for landscape and scenic photography and can also be an amazing performer for interior and exterior architectural shooting. Three Aspherical glass elements offer correction for distortion and four SLD (Special Low Dispersion) glass elements employed for effective compensation of color aberration. It is also perfect for press or social situations where the photographer often has no control of the distances and size of the subject groups.

Sigma 12-24mm f/4.5-5.6 AF II DG HSM Lens for Nikon Digital SLRs Review

After reading all of the reviews about distortions on this lens compared to the
older version which I just sold I was very hesitant ordering version II.
But with Amazon return policy I could not go wrong.
Got this lens and I was very surprised.
Distortions are not as bad as in reviews. In the worst case
if straight lines are very close to the edge and the edge is just few feet from the lens
I get barrel distortion. Easily fixed and at the most I lose 1mm. Probably less.
In real life it almost never happens. This lens is also very sharp wide open maybe even slightly sharper than Canon 16-35mm F2.8
at F4.
On the other hand corner sharpness is almost 2 stops better than previous version of this lens.
Not only that but on previous version corners were smudged unless stopped down to at least F8 or more.
On the new version corners are just less sharp but still very acceptable wide open.
Combine that with much less vignetting (at least one stop less) and we got a winner here.
I use this lens on Canon 5D MK2.
I would give it 4.5 stars if I could.
