Question: I have a Panasonic LUMIX DMC-G3 camera. Will this lens work with my camera?
Document: Auto- and manual focus stopped working forPanasonic Lumix 100-300mm f/4.0-5.6 G Vario Aspherical MEGA OIS Lens for Micro Four Thirds Interchangeable Lens Camerasapproximately 7 months after purchase. The focus still work fine on other lens with my G3, so it is not a problem or trouble with the camera body or the conditions in which I'm taking a photo, but something wrong with the Panasonic 100-300mm lens.
I purchased this lens to mount on a Panasonic DMC-G2 micro four thirds camera. With great anticipation, I took the camera/lens combo with me on an early morning wildlife shoot. I was a little daunted when conditions turned out to be dismal...misty rain and very low light. However, I figured that if the lens was all I hoped it would be, I would get some good shots in spite of the conditions.
I have just recently acquired this lens. I also have the Lumix 45-200, and the 14-42mm lenses. This one is by far the best of the three. I have been very impressed with the image sharpness at maximum zoom as well as throughout the focal length range. I am using it with a DMC-G10 primarily for bird photography. Using the 2x digital zoom function on the camera gives an equivalent focal length of 1200mm!
Pictures are crisp and sharp with the lens on a Panasonic Lumix GX1. I like to capture birds in the wild. I had no problems with shaking hands, even in low light. Such good photos with such a low weight lens and camera!
I use this lens on a Panasonic G6 body; it results in a 35mm-equivalent of 200 - 600mm zoom. On a trip to Tanzania last year I rarely took it off the camera; on safari it was on the camera almost all the time. Fantastic lens - sharp, reasonably fast (f4 isn't super-fast but it's decent), and the image stabilisation works well. Lots of handheld shots and very very few were blurry.
My primary interest is bird and wildlife photography and I usually use a Canon 7D camera with a 100-400mm lens. However, I wanted a lighter camera combination to use for hiking, particularly in winter when slogging through wet and snowy trails makes the weight of the Canon a problem for me.I tried the Panasonic G1 / Olympus 70-300mm combination last winter.
That's not a good sign in my opinion - good lenses should hold their value. Perhaps the lens is not selling well because Panasonic can't deliver the GH2 camera.
This becomes a bit less true with the lens hood on it, but I haven't found it to be a problem. It is easy to handle, and on a tripod, I haven't found a need to use a lens mount. The system is so light weight, especially with my Panny GX-7, that it easily is held even with small flexible tripods.Image stabilization seems to work great.
It isn't a magical good pictures device, but it works as well as I would expect IS to possibly work!So in summary, I love this lens, it is awesome for many applications. If you stop at or before 200mm, you would think this is a MUCH more expensive system, and even at 300mm, I am frequently impressed myself with the shots I have gotten. So much to love here, just keep in mind that low-light and fast moving targets will present difficulties.
This lens works well with the Olympus OMD EM5, but switch the lens stabilizer off, since the Olympus body already does a great job. They seem to work against each other otherwise. Magic
Answer: Should work.I'm fairly certain that so far all the micro 4/3s lenses work with all the panasonic models.  The only one I would think would be questionable is the 3d lens.
