I have a Rode NTG-2 mic and it doesn't fix well in the microphone holder.
I think that microphone holder is 21 mm. and mic is 19 mm.
How to fix it?
I see that NX-5 comes with a mic and a piece of rubber that fix this issue, but I don't find the reference of this gadget.
Thanks.

...and, annoyingly, the piece of rubber is glued to the NX5 microphone. It was just a loose piece of rubber on my Z5's microphone and could easily have been removed and used with a different microphone.

Well, certainly there are a million things you could wrap around the NTG-2 to make it fit snugly in the NX5's microphone holder. Maybe stop by your favorite bicycle store and ask for a blown-out inner tube from a bicycle tire, then grab some scissors and make your own rubber shim.

Or just peel the piece of rubber off of your NX5 microphone.

Best,

I peeled the rubber of mine. It was just a short strip of clear double sided tape. The NTG-2 works fine. I just can't use my WS6 Deluxe Windshield unless I mount the mic on the hot shoe. When I'm shooting on a tripod, I put the NTG-2 on a mic stand to avoid camera noise.

I bought an AT mic for one of my AX2000's and it was to small as well. It did however come with 2 small rubber orings that I used to make it fit. If your NTG did not come with them I'm sure you can find some that would work.

I use about 4 O-Rings with my Rode NTG-1 and my AX2000, works perfectly.....

OK.

Thanks for the info.

I had that issue too, with my Sennheiser MKE-80 shotgun mike. The barrel is of narrower diameter than Sony's little mini-shotgun supplied with the mike, and doesn't have that rubber adapter either.

The solution cost me about $1..50 at a local hobby shop. I bought some radio-control model airplane tires of just the right size, and slipped them onto the microphone barrel (avoiding the sound holes of course).

These tires firmly position the mike, but have just the right amount of give to lessen chance of damage and provide some acoustic isolation. I leave the tires on the mike even when it's not on camera.

I have found the hobby shop to be a great resource for small parts, fittings , and fasteners needed in our business.
