What's the downside to Al Canon Mt?

Hey everyone,
I'm looking for a Canon mount and wondering if the Al option has any inherent drawbacks.
Thanks as always for the help.

That's what I have affixed to my camera...never any issues, even with longer lenses (70-200mm). It's incredibly strong. If you start going longer than that (300mm+) you will want to add a either a lens support system, or go with the TI canon mount. Lens support is definitely cheaper.

If your lens has a lens support, then it's best to use it, although you can just about get away with the 70-200mm without one if you're not putting higher than gravity 1G stresses on the lens (e.g. on a car mount). The lens will likely flex/break before the Aluminium camera mount does.

The only real reason to have the Ti mount is thermal stability of the FFD focus distance in extreme temperature variation conditions, and possibly/maybe for renting out a lot to clients who don't look after the gear.

We've had Aluminum for couple of years now, and been flawless. Yes, on longer lenses to be safe just add lens support...

Using the Al since 2012 and never had a problem. Since a while I have as well the Ti Motion Mount (Canon as well). Both work nicely.

Just make certain that you tighten the mount with the larger ring, it is certainly an improvement over the "Native DSLR Canon" mount.

Lens support, as said above for heavy glass, but also for any lens with a stiff focusing ring.

What everyone else said... never a problem. I would just add to be sure to always snug down the lens with the outer ring; some ACs unfamiliar with the camera sometimes overlook this.

I have Ti, while a number of my colleagues shoot the aluminum mount and from where I sit the biggest benefit of having the Ti mount is that it is far more sexy. It isn't physically more sexy, they look extremely similar, it is more a mystique thing. ;-)

Having stated that the caveat is that we have not shot in the kind of thermal extremes or dynamics in which we would expect to really appreciate the difference.
