I know that many telelens have tripod collar accessories but I wonder whether Canon 17-40L will also find a tripod collar for fixing the lens on my small tripod when shooting vertically.

Its not a heavy lens, why not just attach the camera?

It's not setup for a collar. Attach camera to tripod.

The reason that I want a tripod collar for 17-40L is that it is more convenient for me to set up on my tripod. Based on the lens body, I found that the designer has not assigned a spare space for any tripod.
Since that I am now applying a large torque to fix the camera (with the lens attached) on the plate pin for vertical frame and I am really worried whether or not the internal screw would been damaged by my rude hands. ^^

But how about 28-70L. This is definitely a heavy lens and not having a tripod collar (and collar design) may create excessive stress on the plate pin.

Canon presumably is aware of the loads that will be placed on their camera tripod sockets by the various lenses they make, and should therefore design the cameras to be able to support those lenses (or lenses within those weight/torque classes) that don't have their own tripod sockets. Whether a tripod head can hold any given camera without damage to the camera or the head brings other variables into the picture. Foremost, is the tripod screw too deep for the camera's tripod socket? Second, is the head strong enough to hold the camera/lens combination in question?

When I ahd my 17-40L I didn't find any problem whatsoever in attaching the lens to the camera and then the camera to a tripod. The lens is so light that I can't forsee any issues arising with the lens mount on the camera body.
Re the 28-70L, I still have that one and again have found no problems at all with using it on any of my SLR's.

I do not have problem using 28-70L on my camera attached on my Manfrotto 190 with 141RC ball head but definitely shooting vertical frame with camera attached on Manfrotto 724B is a problem as the weight of the body and the lens combined causes the screw to unintentionally slides downwards following the gravity.

Tighten the screw a bit more and it won't happen ;)

You just don't need a tripod collar with the 17-40. The key is the location of the centre of gravity in the lens/camera. If it's forward to the lens mount then the lens should be supporting the camera through a tripod collar. If the C of G is in the camera then the camera supports the lens.
Having said that, I have a tripod collar on my 70-200 and after using it for about a minute I wished that ALL of my lenses had one! Just being able to flip from horizontal to vertical without touching the tripod's ball head was great. The weight is kept over the centre of the tripod, so there wasn't any off-centre torque trying to loosen the tripod screw. It didn't require any kind of camera rotating bracket, and the camera didn't change height when I went from vertical to horizontal, or vice versa.
I know why this can't be done of course, but it sure would be nice!

There is no tripod collar for the 17-40. If you want to shoot in portrait format with having your camera and lens off centre on the tripod and out of balance consider an L bracket for the camera. That will allow you to mount the camera sideways on the tripod.
Several manufacturers, such as Really Right Stuff, make L brackets for specific camera bodies. They will fit any tripod head that accepts Swiss Arca type quick release plates.

Thanks very much. I think I found my solution in my thread. It's "L-bracket"!
