Excerpt: I didn't know that I was taking half a picture until I bought this super wide angle lens by Sigma. Now every shot is a full picture! Good for taking architectural shots, indoors or outdoors, it also gives you good colors and details. Buy this lens and you won't regret it!
Pros: Angles, Colors, Details, Durable, Easy To Use, Lightweight, Reliable
Excerpt: This lens has exceeded my expectations. I am using it with a Canon EOS T3i. The quality of photographs is exceptional. Highly recommended. Also, the service I received from B&H is second to none. Great experience with the sales staff.
Excerpt: This Sigma lens for the price range is remarkable. What a surprise. I almost purchased the Rokinon 16mm wide angle, but waited. I'm so glad I did. What did I gain by purchasing the Sigma lens, A 10-20mm wide angle zoom, a removable lens hood and the ability to attach filters, not to mention a good quality result. I am very happy with the product and so glad I made this choice.
Summary: This Sigma is one sharp lens. It does have some barrel distortion especially at the 10mm end but if you are not carefull the perspective distortion will get you even worse. (Keep faces away from the edge of the frame and not too close or heads will become footballs.) I am a professional and put this into service officially yesterday and it performed flawlessly. I am a stickler for sharpness and I am impressed by this Sigma.
Excerpt: Back a few years ago I bought a Nikon D5000 for real estate pictures primarily, and I wanted a wide angle lens which this camera had at 18mm but now that I have this lens it is more than just wide angle, it is about quality optics. The stock lens that Nikon sends out for the Digital SLRs is pretty lightweight and seems to be plastic verses precision ground glass. The stock lens in the auto mode is a bear to get focused and take a picture and the Sigma is immediate.
Pros: Easy To Use, Improves Picture Quality, Interfaces Well With Camcorder
