Hi. I'm new to PictureSocial and noticed that there was no group for users of the Sigma 10-20mm lens, so I've started one. Please stop by and join us if you use either version of this lens.
Great lens, but lots of distortion at the wide end. I love the width it offers me, but you've got to be very careful with your horizons as well as the shapes of buildings. It just wonks them way out of shape. But if you know how to use it, there's nothing better for the price. I have the older version.
