Sharp as a tack, fast and accurate focus, compact and relatively light, and fantastic build quality

optically superb, excellent build (weatherproof!), slightly wide but for me perfectly normal

Very well built and looks great on both my xt-2 and x-t20.

, it's fast, it's well built, it's light ... absolutely a game-change for me ... and I came from the APS-C

Excellent build.
