iShoot Metal Lens Collar Tripod Mount Ring Compatible with Canon RF 100-400mm f/5.6-8 IS USM, Lens Support Holder Bracket Bottom is Arca-Swiss Fit Quick Release Plate Dovetail Groove

This sure does a good job of holding my lens on a tripod. Since this was not originally built and designed specifically for the 100-400 mm Canon Rf lens structure, you must be careful in slipping your lens into the ring to avoid any damage due to misalignment or improper tightening of the screw knob. Other than that, it works perfectly for me as I do not do "professional-level" camera work.

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 lensIt 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.

Un ottimo prodotto, ben fatto e ben rifinito. Vale più del suo prezzo.

🟢 Le collier s'adapte parfaitement à l'objectif et fournit une monture très solide.🟢 Le montage et démontage, facile et simple.🟢 De fabrication très solide en métal.🟢 On peut accéder aux commutateurs sans problèmes.🟠 Pour faire pivoter l'appareil photo en mode portrait vertical une fois monté, seul l'utilisation du trépied/monomode a condition d'avoir une rotule.🟠 Je trouve le prix excessifs malgré tout.

先日、RF24-240mm用の三脚座を購入したのですが、EOS R3では、バッテリーグリップ部が干渉して、取り付け出来ませんでした。そのショックがあったので、届くとすぐ、Ｒ３に取り付けられるか、試してみました。無事、取り付けが可能でした。よかった。このレンズにも純正では三脚座はありませんので、これからどんどん使っていこうと思います。ちょっと気になったのが、レンズ鏡筒がプラスチックなので、この三脚座をしっかり取り付けようと、ネジをグイと回すと、「ミシッ」という音がします。どこまで締め付けていいのか、不安ですね。
