Summary

In the first review, we looked at three different lenses,each lens has its strengths and weakness. In this review we had to keep in mind the first review and tried to simulate the original conditions when taking photographs to allow the reader an opportunity to compare all five lenses. The time lapse between the two reviews was close to three months so there are some differences but we tried to incorporate as much similarity as possible.

The best lens for the money is still the Sigma DG 12-24 F/4.5-5.6. The lens has the least barrel distortion, vignetting, chromatic aberration, and is reasonable sharp. If you are trying to get the best lens on a limited budget then choose either the Sigma 10-20mm F/3.5 EX DC HSM, or the Pentax DA 12-24mm F/4. However, if you don’t mind the variable aperture zoom, the Sigma 10-20mm F/4-5.6 EX DC J  is almost as good as the other Sigma and Pentax lens. The Sigma 10-20mm 3.5 and the Pentax 12-24mm are sharp and fast, which makes them great for interior views. The negatives that the lenses bring to the party, such as barrel distortion, and chromatic aberration, can be corrected if necessary with software.

When you consider the two additional Sigma lenses in this review, alongside of the first three in the previous review, the Tamron SP AF 10-24mm F/3.5-4.5 has slipped to fifth in the ranking. The Tamron lens is sharp, if you stop it down and it still has the widest range of the five lenses in the review.
