Great lens for the Blackmagic Studio camera if you want to use a LANC controller. Zoom and focus are both very smooth. You may want to consider a lens with more zoom if you are father away from your subject though.

This is a everyday lens. It is strong and weather tight so those rain drops are fine. I used it to replace the lens that came on my camera. Having the ability to use as a macro makes it the best choice for me.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

I got this lens as a kit lens bundled with my EM-5. All in all it is a good lens. Good things about it: 1. It is a durable lens, weather, splash and dust proof is a great feature. I had some chances taking photos in a super snowy winter night, with this lens, I am worry free.

A bit soft around the edges compared to a prime lens but a good all purpose lens.

The Olympus M.Zuiko Digital ED 12-50mm f3.5-6.3 EZ Lens ($499.99 direct) is a 4x zoom lens for Micro Four Thirds cameras . It covers a wide angle to telephoto field of view, equivalent to 24-100mm in traditional 35mm photography, and also sports a special Macro function that allows the lens to focus...

This 4.2x zoom lens from Olympus is compatible with Micro Four Thirds system cameras and provides an angle of view equivalent to a 24-100mm lens on a 35mm camera. Unusually for a lens covering this range the maximum aperture is rather slow at the telephoto end at only f/6.3.

a great kit lens for the om-d. can easily be an everyday lens, when it's raining and you still want to use your camera without a plastic bag around it.

Nice build quality, even if it's plastic; very good for video in bright sunlight l-fn for video strong "Pumpy" zoom control weatherproof easily one of the best kit lens for MFT not too big on a om-d

aperture is not fixed and very slow; Not really suitable for Variable nd filters because of the round front element

The power zoom and focal range make this a great video lens, and it also doubles as a decent macro lens too. Weather sealing is good but image quality for stills is a little disappointing and f/6.3 is just pitiful. So for stills, it doesn't satisfy me - thankfully, I have the 12-35 too.

Versatile - does it all

Unspectacular - doesn't do anything very well

Compared to other kit lenses I've owned from other systems this is the best so far! Surely it doesn't match a prime lens for sharpness or shallow DOF, but what it does it does well. Really find the macro function and 12mm wide end very useful. Rating is only to be compared with other kit lenses.

Useful 12mm wide end; Overall good sharpness; Macro function

A bit slow aperture
