I’ve finally finished the Sigma 10-20mm F/3.5 review, this is a newer design than the one I reviewed a few years ago. If you’re wondering what the differences are between the two, you’re in luck, I’m working on a comparison involving the two Sigma lenses, and the Tokina 11-16mm F/2.8, that’s the reason the reviews are taking so long. The comp will be available after the completion of the Tokina review. All three lenses are on every Real Estate photography websites list of “must haves” and are purchased (mostly Sigmas) by many people that want to get started in Real Estate photography.
The Sigma 10-20mm F/3.5 HSM has some really nice qualities, and a couple of negatives. Is it worth the extra money over the less expensive older model? Check out the review for the answers.
