First off, I want to clarify that I purchased this lens for videography purposes, not for photography. My initial out-of-box observations were that the kit was packaged nicely, with a portable lens sleeve included. The lens itself has a sturdy, light build quality. I am using this lens with the Blackmagic Pocket Cinema Camera 4k. Considering this camera does not have image stabilization, I was eager to see how the IS in the lens compensated. It handles minor handheld shake quite well, and I would recommend this lens if you have a cinema camera without IS. Image quality out of the lens is superb, and ultra sharp. I am blown away by every shot that comes out of this lens. However, my only complaint with the lens is that it has very noticeable vignetting when at it's shortest focal length of 12mm. To eliminate this, I've had to shoot at 13-14mm. I hoped this wouldn't be an issue, especially considering the price of the lens. But other than this issue, it's a wonderful lens to work with. I'd recommend this lens if you are interested in any form of professional videography or perhaps if you shoot landscape photography.

This is a great multipurpose lens. A must have for professionals issuing this camera!

Small, compact, and focuses quickly. I bought this for my old Lumix G5 because that camera does not have ibis, and I've recently gotten into using some of my old camera bodies that have been collecting dust for the past five or six years.. the optical stabilization in the lens is nearly as good as the in body stabilization on my em1's, so I'm very happy to have this on my old, non-stabilized G5. On a Lumix G5/7/85/95, this is a perfect and smaller compliment to my OMD system with the 12-40 F 2.8. It's not quite as sharp as the Olympus lens, nor does it feel as solidly built, but it's very sharp across the board and it's so light and compact on the front of a Lumix camera that it's almost like a moderate size Prime. For somebody who wants excellent IQ in a small form factor, this is a great choice. For its performance it's five stars, but even though it's been out for several years it's still a relatively expensive lens so for Value I can only give it four stars.

Got this to pair with my new GH5 and I'm really enjoying it! Great build quality, very good performance as well. Love the stabilization and it only gets better with the IBIS of the GH5! Would strongly recommend this lens as a great walkaround, all purpose lens.

This is one of the best lenses that I used! Great picture quality, and affordable! If you buy a G7 w/o this lenses your missing on great pictures and amazing 4k videos
