macnerd Posted October 31, 2014 Share Posted October 31, 2014 Tonight, I was filming with my gh3 and after about 30 minutes of use my camera started acting up. While filming I tried to zoom in on a client an then my lens 12-35mm panny started vibrating. Looking through the viewfinder the image was vibrating on the screen an out of focus as well, I turned it off, took the lens off and still the same thing. I can only film in manual but I cannot zoom, please help as I have no idea what caused this problem as it was working perfectly fine.

andy lee Posted October 31, 2014 Share Posted October 31, 2014 will the zoom barrel turn ok manually? is the track inside free and turning ok? have you accidently changed paramaters in the menus - go back and check teh manus are correctly set up for how you use it Quote Link to comment Share on other sites More sharing options...
macnerd Posted October 31, 2014 Author Share Posted October 31, 2014 all the settings are the same, I was actually filming and the problem just started.. the zoom barrel turns fine. when i turn the camera on i can hear something like a motor running, like its trying to recoiling something.. when i zoom nothing gets in focus , it just blurred image of the object Quote Link to comment Share on other sites More sharing options...
andy lee Posted October 31, 2014 Share Posted October 31, 2014 you are focusing manually arent you - if you are filming video always use manual focus not auto focus focus all manual zooming all manual dont let the camera try to do anything automatically - turn all that off in the menus Quote Link to comment Share on other sites More sharing options...

What is working and what is not working? Maybe there are some gears jammed on lens. Try to shake the lens when switching on. My Pana 100-300 autofocus jams too and it works if I shake it.

macnerd Posted October 31, 2014 Author Share Posted October 31, 2014 i had to resolve to focusing manually all night. now i'm in manual an when i'm zooming in the lens is vibrating thus causing the image on the sreen to get a bit blurry, when i stop zooming it works fine.

andy lee Posted October 31, 2014 Share Posted October 31, 2014 ok so how are you zooming this lens - I take it you are turning the zoom ring on the lens describe if the image is shaking only if you are moving the zoom ring or when the zoom ring is not moving?

Quirky Posted October 31, 2014 Share Posted October 31, 2014 If the lens has OIS and it's on, turn it off and try again. I take it you are not zooming the lens whilst recording, right? Anyway, if that doesn't help, it might be a moisture problem or something. Try letting both the lens and the body be in some warm-ish and dry place overnight, and then try again. Clean the contacts. Or finish the shoot with manual prime lenses. Try if you can find another mFT body to test the lens with, and vice versa. Quote Link to comment Share on other sites More sharing options...
leeys Posted November 1, 2014 Share Posted November 1, 2014 Turn off IS, your IS motor/circuitry is malfunctioning. Send the lens in as soon as you can afford to. Quote Link to comment Share on other sites More sharing options...
