Lightweight, versatile. There is no alternative. Ideal for filming a child indoors. 35 1.8 - very good for the price and sharpness, but there will be only portraits or you will have to crawl around the corners and squeeze into the walls =) When you pay a thousand dollars for cropped glass with a Zeiss tag, you want to get the perfect thing, but there are no ideal things =) This is an acceptable compromise.
