It has a very light and solid built and feels sturdy. Even though it is 18-300, it is still very compact and almost the same size as other lenses in the market
Even though it won’t really fit in the professional lens category, I was still really impressed by its silent focusing HSM motor, which helps focus faster. The rubberised zoom rings zooms with ease, it does tighten up after a certain point. Optical stabilisation does a good job.
At 18mm sharpness in the center is excellent at maximum aperture and further improves between f5.6 and f8.
Even at 300mm performance is very impressive with only a slight reduction in sharpness, Sigma deserves a thumbs up for that.
