Review: A better mount option - When mounted the collar doesn't give you a perfect balance at the plate. If you set it on a table it's camera heavy and falls backward, even with the lens all the way out, but not by much. You could always mount a longer Arca swiss plate to it as well if the balance wasn't what you wanted. The base plate is actually removable and you could reverse it which may balance it better but then you wouldn't be able to also use the BG-E22 grip (it's fully compatible with the grip the way it is though). When I lock it on the tripod though it feels much sturdier and better balanced than if I'm mounting it via the camera tripod mount. The switches are still accessible, but naturally harder to access than without the mount. It's very well made and feels strong and sturdy, when you tighten it on the lens the screw tightens all the way onto itself and locks very securely to the lens so it appears you cant over tighten it and damage the lens It hasn't scratched my lens but I've not used it often, remember the lens is maybe polycarbonate so it may be possible, I just haven't had that happen. I think it will be ok because there is no movement once it's locked on. I still take care when putting it on though. My purpose was to give me a more secure tripod method as I use the lens for not only wildlife on occasion but landscapes, and more so need this for long exposure, but as I say I haven't had much chance to test it in that scenario, but it looks good to fit that function.
Review: Awesome - Awesome accessory for the lens and this will relieve stress of the camera when mounted in a tripod. It's made of metal which will last for a long time. When used it also help in steadying the camera when shooting.

### ⭐⭐⭐⭐ Nice Collar with One Fatal Flaw
*by P***G on October 31, 2022*

The collar fits the lens securely and provides a rock solid mount. No complaints there at all. The problem is, the collar does not allow the camera to be rotated into a vertical portrait mode via the collar. I can see why this feature is not available (Interference with the switches on the lens), and would be difficult to provide, so no fault of the design there. Nevertheless it severely limits the usability and value of the collar.
