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

None at this time

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

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.

it out both on several indoors shots under less-than-ideal lighting conditions and was pleased in most respects, and outdoors. very good results on even moving subjects. Really good product, with highly applauding performance. Image quality is simply awesome. 5 stars for that.

On paper the Olympus M.Zuiko 12-50mm f/3.5-6.3 EZ looks like a rather conventional standard zoom lens but it is somewhat unusual in a couple of aspects. You may have noticed the "EZ" in the lens name - this refers to an lektro-magnetic oom mechanism, usually also referred to as power zoom.

A versatile general-purpose lens for Micro Four Thirds cameras, which features motorised zoom control for smooth movie shooting.

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

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