I bought both the Sigma 50mm and 20mm f/1.4 ART lenses for concert photography, mainly for one dark and dank venue that I was house shooter for. Long story short, lighting got even worse and I've stopped photographing for them. While I'd be happy to keep this excellent lens I never use it, Lightroom shows only 195 photos in my catalog. Purchased new in 05/2018 from Adorama. It's in excellent shape, glass is pristine.
