No matter how many lenses you own, chances are that you have one or two that you end up reaching for more than the others in your bag. As a long time Olympus shooter I own most of the micro 4/3 lenses on the market today, and I use many of them quite regularly depending on the situation. That being said, I am finding that the new m.Zuiko 12-100mm f/4 PRO is spending a lot more time attached to my camera than any other lens. It has become my workhorse lens, for a number of important reasons.

Overview
The 12-100mm is a constant aperture f/4 lens that measures 116.5mm long by 77.5mm in diameter with a 72mm filter thread. Like all Olympus PRO lenses it has a programmable lens function button, a manual focus clutch and is weather-sealed, meaning it is splash proof, dust proof, and freeze proof.  It has 17 elements in 11 groups with high quality construction and the Z nano coating to reduce glare. Perhaps most impressive is the 5-axis Sync image stabilization that works in tandem with the in-body image stabilization of the OM-D E-M1 Mark II to produce up to 6.5 stops of IS.
