I recently purchased the Canon XA45 and bought an Azden external microphone. Problem is, it's too small for the Canon Microphone holder. Is there a rubber spacer available to purchase? I can use the hotshoe attachment provided with the microphone, but would rather keep that spot open for other attachments. Thoughts?
Maybe see if you can find a rubber o-ring/grommet in a hardware/plumbing store that will work ?
Can't post the link but a YouTube search for "How to Mount a Shotgun Microphone on Canon Camcorders - XA11 XA30 C100 C300" will pull up a video where this was done.
I suppose you could also try wrapping some closed cell foam around the mic (e.g as used for insulating plumbing pipes) but I suspect the microphone would be prone to slip unless the foam tape has an adhesive backing.
