Olympus M.Zuiko digital ED 12-100mm 4.0 IS PRO

There are many ways to judge the results of the Olympus M.Zuiko 12-100mm f/4 IS PRO. If you want to phrase it in a negative way, you may call it a jack of all trades and a master of none. However, that's unfair really. You could also argue that it doesn't show any true weakness and that's quite something considering the range. More so than the charts, the provided sample images may show that you can use this lens at pretty much all relevant settings with very good results at the wide end and still good results at the extreme long end. Lateral CAs are no issue. Vignetting and distortions are handled nicely (albeit somewhat lossy) via image auto-correction. And the quality of the bokeh is pretty decent for a zoom lens. The build quality is very good and complies to professional standards including weather sealing. Yes, it is a comparatively big lens by it's not a brick either. I was certainly never annoyed by the size/weight during the field sessions. The AF is speedy and noiseless. A differentiator is the image stabilizer. Of course, many lenses have image stabilizers these days so it's hardly a novelty. However, this one is more efficient than most - especially when combined with an Olympus camera that is compatible to "Sync IS". Whether you can achieve the claimed efficiency of 6.5 f-stops or not - it's class-leading in any case - by quite a margin. So would I take the Olympus M.Zuiko 12-100mm f/4 IS PRO to that remote island ? Yes, I would. Highly recommended (within its scope)!

The Olympus M.Zuiko 12-100mm F4 Pro IS is a solid option for travel and generalist photographers using the Micro Four Thirds system. It doesn't grant you the blurriest backgrounds nor the most compact dimensions available among other Olympus lenses, but it's well-built, offers excellent stabilization and gives a great zoom range to match almost any situation you find yourself in.
