Canon 100-400 tripod ring question

[Rookie 300d]

Could someone answer me a simple question. What is the thread size on the tripod ring of a 100-400 is L as mine is finally on its way, but I dont want to get it here only to find I have to wait another 2 weeks for a replacement plate for my tripod head. I cant find this information anywhere.

Thanks Paul.

Same as on the bottom of the camera body - not sure of the size, but the same as found on the bottom of your camera

1/4" Whitworth is the standard bush size in the camera base

3/8" Whit.is the other standard bush (as on Manfrotto tripods)

Whitworth ?? Thought BSW as been obsolete for years. Are n't threads governed by some ISO or other these days.

As far as I can remember the camera bush has been 1/4"Whit (or 3/8 Whit)
just as fishing tackle used 3/8 BSF for bank sticks and landing nets

the thread is exactly the same as your camera
