a) Arrived quickly and well packed. b) Tried it out for the first time a few days ago - superb range of zoom which makes composition of shots so much easier and interesting. c) Not nearly as heavy or bulky as we had feared - in fact it feels not much different on the camera than our 12-40 pro. d) Should be excellent for travel and exploration without need to carry other lenses.

Beautifully sharp lens. Zoom is super smooth. Autofocus is fast. This quickly became my default lens for non-birding shoots. 12-40 lens is now semi-retired.
