After considering many options I recently purchased a GH3 strictly for its video capabilities. My purpose for its use however has left me a bit frustrated in trying to find the right lens. I am shooting interiors of homes, flying the camera on a stedicam providing a walking tour type of video of the home interiors so I need a ultra wide lens which is not fisheye. Problem is the options I keep retuning to i fear are not really fast enough to produce the results I am looking for when shooting in the sometimes lowlight conditions of home interiors. The pros I know use 14mm full sensor lens for this type of videography. In order to emulate that as close as possible with a GH3 and MFT lens the best i can figure I really need a lens in the 7-9mm range or as small as I can get which is not a fisheye of course. The a panasonic MFT 7-14 4.0 is of course an obvious solution until you read the reviews which repeatedly indicate its not such a great performer in the type of low light conditions such as I have described will be my primary purpose for the camera filming home interiors in the manor I previously described. Admittedly I still have a lot to learn about what non MFT lens might work as an alternative for what I need. At this point however their doesn't seem to be a MFT solution. If anyone has a suggestion as to what I should be looking at as an alternative that would work with a proper adapter of if I have missed a MfT solution please help a brother out! I really was hoping I would be able to use the GH3 to achieve this kind of ultra wide low light cinematic video shooting . I'm afraid I have made a costly mistake, got a little over enthused about the GH3 and didn't think this all the way through before making the purchase. Don't want that to happen again with a wrong lens choice.
