Canon tripod mounting thread

Yorkie Dad

I want to 'change' my Canon tripod mounting threads from the original 1/4-20" thread to 3/8-20" thread. I called Canon and talked to parts dept. They had no idea what I was talking about - and said that they would only sell me original part (1/4-20").
The tripod mount has 2 (very small) Phillips screws that hold it on camera. It appears that this could be removed and replaced with the desired thread, if you knew a Canon camera that originally came with 3/8-20" then Canon would sell the thread component to you.
It would seem (to me) that there must be an adapter plate (1/4-20" male and 3/8-20" female thread) that would also accomplish this change - but, I have searched and not been able to locate anything specific to cameras.

Any thoughts/suggestions would be appreciated.

Thanks,
Art

Purchase an Arca-Swiss camera plate from ReallyRightStuff.com and their corresponding Arca-Swiss clamp for your tripod head, which does fit a 3/8" thread and you will be much happier never threading a camera body to a tripod again.

Better yet, purchase an L-bracket from RRS and their BH-55 ballhead, and you will be even happier. Trust me here - Ask Ian or Andy or any others here if they still screw their camera's on a tripod. That is so 1980's:):

Go to reallyrightstuff.com and read their sheets about camera plates and their uses. They make using a tripod fun again.

I just looked at the bottom of my Canon, and while I see those screws, they don't appear to be related to the tripod mount threads. They appear to be holding something down in the interior of the camera, as they don't even look like they can be used to take any external part or component off of the camera.

At least to me, anyway.

Ok. Thanks for the responses I will check out the information on the mentioned site.

Before you get all crazy, look for the adapter. I think it's less than $5 and
screws right into the 1/4-20 hole.

There are two different thread sizes for tripod points. 1/4-20 and 3/8-20.
Most cameras have the 1/4-20 size. One of my lens uses a 3/8-20.
Not really sure why this is.

There is a reason why . . . most common tripods are made in Japan, these have the 1/4

There is a reason why. Most of the consumer (read less expensive) tripods are made in Japan or China. These use the 1/4 inch thread, which fits nicely into the bottom of 35mm and digital cameras.

However; the more expensive Professional tripods (Bogen, etc.) are used for heavier cameras, 600mm lenses, 4X5 view cameras, etc. So these have the 3/8" heavy-duty male threaded screws. I have a nice tripod and purchased a Bogen pistol grip ball-action top for it. Obviously it did not fit, so I had to drill through the 1/4 inch screw and replace it permanently with a 3/8 inch bolt that goes through the top of the tripod. It works, but I really need a more heavy-duty tripod. Only draw-back is the weight.

Wait 'til their catalogue shows up in your mail. :bluduh

Its actually 3/8"-16, which is the "European standard". As the other posters mentioned--it is worth switching to an A/S style quick release plate and clamp setup. Once you have the clamps and plates on everything you will find yourself actually using your support devices more often. (At least I found myself more apt to throw something onto the tripod / monopod / superclamp when it takes just a second.)

And there are a whole slew of different mounting plates too

I really do like the Arca-Swiss standard though. I bought one of the L plates
for my camera and have been very happy. And you're right, switches is well
worth it.
