If my menory serves me, it's not any standard size (ie 49mm, 52mm, etc). Basically it'll only thread into the other parts of itself.

The Canon tubes are 60mm. But, If not sure about the Nikon ones.

No kidding. I guess I'll have to buy one. I thought I read somewhere it was 55mm.

Hey Car3o,

When you get it could you take detailed pictures of it together and taken apart and stuff? I'm sure a lot of people look over these things and wonder about them.

Thanks.

Yeah, these extension tubes sure are a mystery - they come in all sorts of thread sizes. Here's a great link tackling the problem:
