  1. Hi, I'm not too sure who to ask about this so I'm hoping you guys might be able to help. Ive just bought a new GH4, Sigma 18-35mm, and Metabones speedbooster EF to MFT ultra adapter. When filming there is a very noticeable buzzing noise on the audio. I have researched this and found that buzzing was a known issue to GH4 cameras, but after seeing videos from people with this problem, the buzzing noise from mine sounds very different and doesn't seem to be affected by the same things. I have found that when I unlock the lense the buzzing disappears, but when the lense locks back into place it starts buzzing again. Really not sure if the camera, adaptor or lense is the problem?? any advice you could give would be a huge help. thank you lense attached.MP4 lense unlocked.MP4
