I've been shooting with this lens for two years, and it has a very bright F-value, making it great for low-light situations and producing beautiful bokeh. It's lightweight and takes great pictures, so I used it on my Nikon D5500 DSLR. I always used a filter, so the lens is completely scratch-free and in excellent condition. You can use it comfortably as there is no mold or clouding inside the lens. I've included some photos taken with this lens.
