Hi All, I know youtube has been around a long time but I just caught the bug and now I really want a new lens or two. Darnit I need a flash or two as well...... wife will make me trade body parts for photography equipment. I have been needing a uwa for a long time now and it seems I have been a good hubby recently. I have landed a 360 shoot for a large furniture store so I want to get either a sigma 10-20 (slower one) or a tokina 11-16. What lens will be better suited for me to use for interior architecture and dslr videos shot with my a 57. Ive got a 24 inch slider and a dslr stabelizer. I think the faster tokina would be better. But I am no lens wizard. Please help me decide or if you have a better suggestion for under $700 it would be appreciated greatly.
