Olympus M.Zuiko Digital ED 40-150mm F/2.8 PRO

Just the lens I wanted for an amateur boxing home show. A constant f. through the zoom range was needed for fast action in a poorly lit working man's club. Harrisons had it in stock at a good price (for "proper" retailers) and just when I needed it to claim the Olympus cashback offer.

This is the single most useful, and optically the best, lens I own. I use it mostly for wildlife and nature photography and video. It is very sharp, zooms very well and smoothly and focuses easily. Although it is only a 300mm equivalent I find myself using it for wildlife more than the 100-400mm. I have used it with a 2x teleconverter but I much prefer it without. I use my camera everyday on 1-2 hour walks and it is a great lens for those occasions when a bigger lens just gets in the way.

OM System's rebadge of the vintage Olympus M.Zuiko Digital ED 40-150mm F2.8 Pro remains one of the best lenses for Micro Four Thirds cameras thanks to its excellent picture quality, brisk autofocus, and lightweight build.

Great picture quality, manual clutch and compatibility with teleconverters make it one of the best lenses for m4/3 system especially when paired with OM-1 camera.

The use of the product covers my requirements. I like the fact the lens is compact and this makes easy to use hand held.
