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

Is this a new lens your waiting for. I have one and the auto focus resuts are not what i expect, a little fuzzy. and it won't lock on to the subject I.E. a bird in flight.

OFF TOPIC REPLY:
In one sentence, you just took me back nigh on forty years, to my youth, coarse fishing in the fens with my rods, one hand-built by Jack Clayton (inventor of the swing-tip - I used to be in his shop most weekends) and the other hand-built by George Clark (a Boston barber who also made and sold fishing tackle - my brother worked in his shop on Saturdays and saved George from the hassle of interrupting a haircut to sell maggots and wash his hands before returning to the Barnet).

I cant see what this has to do with the thread size, but i would suggest that your problem is user error and not the lens
