Summary: had to replace my first one of this model because it became chipped on a small fall, its not a fast aperture, its wide enough to be 8 feet away, auto focus is slow at low aperture, yet it does what it advertises.
It is the sharpest lens you can buy at F/8-F/10 at 14mm

Summary: If you're looking for edge to edge sharpness at 14mm (28mm equivalent) at F/8-F/10 specifically, this lens can't be beat. However, anything outside of that it starts showing why it's a budget lens. The zoom is rough. Don't expect smooth zooming during video.
Summary: Tiny, easy to carry around, super fast slilent auto-focus, and Mega OIS image stabilization does help a great deal in low light situations. Image quality is very good considering it's price and zoom range. Shoot in RAW to extract full potential of the micro 4/3 camera. If you shoot JPG, image will always come out blurry. If you always shoot in low light and high ISO, image will always come out blurry due to noise reduction image processing of the JPG engine.
Summary: Bought this lens for my Panasonic Lumix GX1. I have 4 lenses for the camera: Sigma 19mm F2.8, Sigma 30mm F2.8, Olympus 40-150 'R' version. Optically the three other lenses are superior to this one. But as a kit lens and for the price (I bought it for $89 used), I won't complain anything. It is not as sharp or contrasty as the 2 primes or the telephoto lens, but it is probably the most useful lens when you walk around the city snapping away.
Summary: My wife bought this as part of a used G2 kit here on Amazon. I have cropped and adjusted the lighting a little bit so that I can use it on Facebook. To me this lens seems sharp... so sharp that I worry about cutting myself while handling its files... <rimshot> I will add the portrait to the rest of the pictures for this product.
Summary: Bought this lens for a mere $99.00 Great lens I would say, although it is plastic mount and not metal mount, nevertheless, this is what makes this a very light lens. Has a very quiet focus, would be nice if it had an image stabilization switch on the lens itself though. I am using this lens on a Lumix G1 and a PEN E-PL1 and it works very well on both of these cameras.
