Summary: Pros: 28-84mm focal length in 35mm equivalent with Pan 2x crop factor, OIS, great shallow depth of field Cons: very hard to zoom, not consistent, makes mechanical cracking noise, seems like my GX1 need lower F stop or wider Aperture in low light to compensate digital noise in videos...
Summary: I bought one of these and had bad luck.. it was very sticky/jerky trying to zoom in and out; probably just a bad one, but I also noticed that it sort of felt cheap. I ended up paying more for a Lumix Vario 14-45mm and was amazed at the higher quality and advanced features with the OIS control, etc.
Summary: I received this lens as part of a GF5 kit. Before purchasing the kit I was aware of its reputation of not being a stellar lens and yet I have still been disappointed. For several years I managed a professional photography store and tested many kit zoom lens.
Summary: I just invested in a Panasonic DMC-G3 system and got the 45mm Leica 1:1 macro, 7-14 zoom, and 45-200 zoom as companion lenses. I used a Nikon D2x with 13 lenses for years previously so have considerable experience with build quality.
Summary: I'm surprised anyone likes this lens. It works like an old 70-300 Canon lens you can get for a hundred bucks for Canon Dslrs. Plastic and cheap feeling and when you try to zoom it sticks and grabs and I hate it actually. It's not worth the money and it shouldn't be a kit lens.
Summary: I've been a professional photographer shooting Canon for over 30 years. I bought a LX5 as a "point and shoot" and it is an amazing little camera. I was thinking that the GF2 would be similar with even more goodness. Gave the LX5 to my wife and bought the GF2 with this lens.
Summary: I bought the Panny G2 with this kit lens and the image quality does the 4/3 format injustice. In fact this lens is so bad, even my DMC-LX3 format comes out ahead in image quality. Seriously even lens from P&S cameras will outperform this lens.
Summary: I found the "Mega OIS" image stabilization to perform well for video but overall, this lens has poor optics in comparison to the 14-45 and does not allow you to extract the full capabilities of Panasonic's excellent M 4/3 technology.
