Has anyone had any experience with this lens?
Anyone with an opinion on it?

Looking to fill a gap between the 20mm and 50mm range, and I'm unfortunately on quite a budget. (The budget being whatever my Old Sigma 150-500mm f/5.0-6.3 DG HSM APO OS AF sells for)

In a perfect world, I will be able to afford the 24-70 2.8, but I'm not holding my breath
