Hi Guys, It wasn’t there when I first bought it I’m also having a really bad hissing sound that’s developed on my Canon C300 Mk3. Any new advice would be very welcome. I’ve shown it to some vid friends and they can’t work it out. It’s definitely not a microphone issue as it’s just as bad without a microphone. I’m beginning to think it needs to be returned. Cheers Donal
