Hi, well the title says it all. I'm mostly shooting indoors in my small studio, at the moment have a 50mm 1.4 on an cropped sensor body with a 1.6x ratio (canon), which is a great lens for portraits, but since I have very limited space in here, about 3 to 4 meters (10 to 12 feet), the 50 is not enough for full shots, even my 18-125 at 18mm puts me on the opposite wall without the full person on frame. I know I should have more space for that, I'm working on that, trust me, but for now I would like to be able to do so, so I was thinking if a wider lens should be ok, I have my eyes on a Sigma 10-20 4-5.6, is this length range a good choice? Or is trying to use this kind of lens in such constraint space a no no for getting a nice full shot??
thanks in advance
