I use this lens on my Sony A 77 II,It has been a pleasant surprise how light and easy to use

TSC, which is incorporated into the lens barrel and is often compared to polycarbonate, has a high degree of elasticity and exhibits little variation in its structure in extreme temperature conditions.

I'm very sorry but this lens is terrible. The sharpness was horrific especially at each end of zooming but macro and extended top 250. Maybe because I'm using a very new Canon (T7i) but this did not produce good images. Perhaps mine got damaged but I kind of doubt that it was broken.

I use this little gem of a lens whenever I travel. Like all super zooms, it has compromises, but the main one of reduced apertures, is compensated for by the high ISO capability of modern cameras. The longest focal length is also very useful for nature and macro shots.

Light; compact; sharp; fast focus; very usable focal range

No full-time manual focus; though I seldom use this on other lenses
