So I've been getting more calls to do real estate photography and other things which require me to have an ultra-wide angle lens. I posted (recently) about which one to get. I'd really like to get the Tokina 11-16 f2.8 but it's out of my budget at the moment (they also just bumped the price $100 on them). So I'm looking for something to get me by until I can save my pennies a bit.
Been seeing the Sigma 10-20mm on sale (used) for good prices. Just wondering if anyone here has experience with this lens for something other than just landscape shots. I'm aware of needing to be careful about getting a sharp version of their lens but it seems like it's not a horrible lens but I've never worked with one.
I don't really like that the aperture isn't fixed but I can deal with that as I'll be shooting at smaller apertures anyway. More curious about the distortion and quality.
Thanks.
