Summary: Great all rounder / everyday lens and if u are new to MFT / gh4 or have no other lenses then this should probably be your first lens. I made this unboxing video to to show u what u get - a nice carry pouch is included - http://goo.gl/SPlMHK I write this review having had the lens for 2 weeks.
Summary: I'n not an expert, so for me this lens is the perfect complement to my GX1 with the 14-42mm power-zoom kit lens: lightweight and compact, fast focus, versatile zoom range and bright. Excellent results!! Just keep in mind that the popup flash will leave a dark corner as the lens is big enough to interfere, so bring the kit lens for your night shots.
Excerpt: I've purchased 2 of these for my GH4 & they work great..esp. for the price. I purchased the 1st one when I bought my 1st GH4 because truthfully, it was the only decent telephoto lens I could get at the time, I would probably compare it to a common "kit" lens but it does work very well in good lighting and it is quite small and lightweight.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Smooth Focus, Strong Construction
Excerpt: I was using the original 14-42 lens that came with my Panasonic DMC-G3 camera and later purchased the 45-200 which was cheaper than the 14-140 which I couldn't afford at the time. Once the price dropped on the lens, I decided to purchase as I was tired of switching lenses. So far so good. I find myself using my DMC-G3 more frequently as I don't have to worry about carrying two lenses around. It's really light!
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
