Canon Aluminum vs. Titanium Mount

[PC Greene]

I think this is a relevant question for this thread...does anyone know if it's safe to mount a Canon 70-200 and Scarlet to a tripod via the "lens support ring" instead of the camera?

Thank you!

I accept no liability for yours, but My Ti mount held it just yesterday with no problems, but we had minimal accessories mounted. I have seen worse.

If you are balanced properly using the lens support ring then the problem isn't the weight of the lens (That is fully supported.) but weight of the camera.

Also the Ti mount is both more rigid and better secured than the lens mount. If you encounter a failure it will likely be the lens that breaks. (But then the camera hits the ground too.) Odds are this will happen not from the weight of the Epic or Scarlet alone, but from combined weight with accessories or an external force exerted upon the camera.

Last weekend, we mounted a 400mm Canon lens on the tripod and "hung" the Scarlet off the back BUT (!) we rigged a support with the tripod handle so as not to put the weight of the camera on the mount. I don't think I would have done it without the extra support, however kludgy it was.

EDIT: Oh yeah, forgot to mention it was an aluminum Canon mount.

Red verified the canon al mount can handle the 70-200 without support.

That's cool but the question should be asked of Canon; How much weight can their mount hold? Clearly it is the weak link in the chain.

Sorry to digress here, but anyone of you know the length of the mount's T20 Torx screws? I'd appreciate if anyone can tell me. Thank you

Not necessarily the best examples yet, but I have had the Canon 100mm Macro L lens and the Zeiss 85mm ZE lens on my Al Canon mount, and with both I had no flex. I love the extra locking ring. I will post as soon as I do bigger.

That's right I spoze...what weight the canon ring & mount can hold is really the question if using the support ring. Thing is with minimal rigging, the balance point of the 70-200 support ring is much better balanced & closer to center than mounting from the Scarlet itself...anyone know Canons position on this?

I doubt they have one, and I don't know if they publish how much force the mounts can withstand. You have to use some common sense. For the most part the force exerted on the mount will be spread across three tiny and short screws. The closer the balance point is to the mount, and the further the force is from the mount the less it will be able to take. If ther is ANY doubt in your mind that you can keep your system safely operating, use support.

Define safe... :-) Much better to get a lens support thing for your rails (Redrock sells one for about $200) , mount the camera on the rails, then put the support thing on your rails to help support the lens. Otherwise I would worry about too much pressure on the lens ring and eventual bending/breaking.
