Tripod Mount Rings - Do you always keep them on the heavy L lenses?

70-200 off most of the time
100-400 on
180 Macro on - parked at 90deg, provides an extra "handle" for the left hand when hand holding.

ivar_rs,
I have never taken the tripod mount ring off my 100-400L

I like to flip it 180 degrees so I can use it as a handle to carry my 70-200 2.8 L and 1DII.

I do the same with my 70-200

Mine stay on ALL the time.

FWIW...

I generally leave them on (70-200, 100-400, 300 f/2.8 ) unless I'm traveling without a tripod and know I'll never be mounting any of the above on said missing tripod.

On 70-200 f2.8L IS, I always have ring on.
I hook ring on shoulder strap of Slingshot300 to lessen load on camera strap around neck.

Also, I know if I remove it, I will lose it - these things are awfully expensive

I remove mine when hand holding my 300mm. I leave it in the trunk of my car incase I need it.

I keep mine on all the time and rest it on the heal of my left hand and use my fingers to zoom in and out.. Works very well for me...

I leave mine on. I place it in the palm of my hand when I'm shooting without a tripod.

I keep them on the lens. I have 5 of them and I want to be sure that I have them when I need them.

I dont feel that they are in the way even though i have big hands...

Mine are on 100% of the time. Same with all my tripod rings (28-300L, 70-200/2.8L and f/4L, 100-400L, 300/4L, 400/5.6L, 180 macro) except the MP-E65mm f/2.8 macro. With that one it's difficult to mount/dismount the lens as with the the RRS lens plate on the foot it won't clear the grip unless you rotate the ring, and unless the lens is stretched out to 5x lifesize, it doesn't really change much about the center of gravity for that lens. Just a fairly useless ring in that case.

I just *know* I will lose one if I take it off, so they stay firmly attached to each lens

I removed the one on my 100-400..

I wish Canon had tripod feet like Sigma that double as handles, Heck even Nikon has a few that have a lot more surface area and height so you can grab the tripod collar to steady your camera as you're walking...
