Topic: Photo "threads" to audio "threads"

[OhioHead]

Silly question......photo equipment uses "thick" thread and audio equipment used a fine thread, looking for a converter.......

LumoPro stand, LumoPro adopter (top of stand) holds my Shure shock mount holding mic bar (it goes to eleven), I can screw the mount 1 or 2 threads down but then I stop......would love for my shock mount to be more secure.

Local camera shop could not help me & have not looked @ B & H yet......help me narrow down my search, please.

It's a very common adapter.  B&H can help you and if you call they'll likely know exactly what you want from them.  I have a compact photo tripod I use for portable audio and had to get the adapter to make the conversion.  The most common one they have is two parts so it's best to call them.  I forget the dimensions of the two but they know it.

Cameras typically use 1/4 inch
"European" accessories use 3/8 inch
US or typical mic thread is 5/8

B and H has adapter for all these. Get a few 5/8 lock nuts too, just in case.

Thank you both for your feedback!

1/4-20
3/8-16
5/8-27 (awkward one)

Anyone know were the awkward US standard originated?  Just seems a poor mechanical engineering choice, even for old big & heavy studio microphones: overly fat and heavy diameter but with a delicate, more easily cross-threaded fine pitch.  I'd think the US standard would be the good old "any hardware-store" standard 3/8"-16 and the European standard would be metric. 

It just don't make no sense.
