Canon 4429B001 overview

  • 1Description

The Tripod Mount Ring C from Canon is designed for the EF 70-300mm f/4-5.6L IS USM and EF 28-300mm f/3.5-5.6L IS USM lenses. The ring makes rotating your lens easier and the built-in tripod collar improves lens balance by screwing into the tripod mount.

Improves Lens Balance
The ring secures your lens to the camera's tripod
Thumbscrews Tighten and Loosen Ring
Having thumbscrews control the ring make it easy to adjust the tripod ring on the go
Gives Your Camera Setup Better Balance
The ring adds stability to your camera and lens. Due to its weight, when the lens is mounted with a camera on a tripod, the center of gravity is shifted to the lens. The ring attaches to the tripod and can be shifted to any position on the lens, ensuring the weight is evenly distributed
Having the camera secured with a ring around the lens makes it possible to rotate the lens between landscape and portrait modes without removing the camera from the tripod. The friction thumbscrews can then be tightened to secure the camera in the desired position. When not needed, the ring can be rotated to an out of the way position
Hinged Design
The hinge provides the ability to keep the lens attached to the camera while disconnecting the lens from the tripod

Canon 4429B001 reviews

Tripod Mount Ring C for 70-300mm f/4-5.6L and 28-300mm f/3.5-5.6L Lenses is rated 4.4 out of 5 by 49.
Rated 5 out of 5 by from Great Quality For some people it may be debatable as to why you need this piece of equipment. The lens is IS and the centre of balance/rotation is not way off without this. Having said that, there are advantages to using this mount ring. It defintely improves the centre of balance. So on windy days when using a tripod, it provides you with the confidence that the setup is stable. The quality of manufacture is up to Canon L standards, as it should be. Much better quality than the off-brand models I have handled. Cost is often mentioned, but once I felt the quality and used it, I didn't regret my choice to go with the genuine Canon mount.

Rated 5 out of 5 by from Outrageously Expensive but Perfect I almost cried paying this much but admittedly, it's an absolute joy to use. Easy on and off, smooth rotation, and very high quality. I tried a Vello after-market mount ring for another lens and while it seemed well made, it was maddening trying to get it on and off (no spring mechanism). You've already paid a lot for the lens, pay some more for the right piece of equipment. I've had this ring for a year now and finally my resentment over the price is subsiding a bit. In the end, this is the right choice for me.

Rated 5 out of 5 by from Expensive and It Is Working Fine! After reading some of not so good reviews on other brands' reviews, I decided to spend the money and be done with this Canon ring. It works as expected. Very smooth turning and seems very well made just like other Canon tripod mounting rings that I have that come with the lenses. Hope Canon can made the long lenses black instead of this creamy color. Other might not agree but that is my wish. After the warranty expires, I will color it black with marker ink. Other than the color, it is a decent quality buy. Now my lens and camera combination no longer feel that front heavy when I use the zoom.

Rated 5 out of 5 by from Overpriced but worthy As most every one says the price is ridiculous for something that should be included with a $1600 lens. With that out of the way it is still an excellent and well made product. I tried a cheap knockoff and upon receipt sent it back since I would not trust it in my style of use. I use mine for hiking and as an attachment point for my black rapid strap and have absolutely no concerns that it will hold the weight and banging around it gets climbing rocks and rough trails.

Rated 5 out of 5 by from Perfect fit! Perfect fit and the color matches 100% - no unpleasant surprises here! Although I was tempted to go cheap and buy a third party knockoff from China, I didn't. I only trust Canon engineering from Japan especially when securing a heavy, expensive lense (and the attached camera). Remember, 3rd party replicas don't go through intensive (and expensive) testing for safety and security. Buy a cheap-O ring at your own risk.

Rated 5 out of 5 by from Necessary but expensive Purchased tripod mount ring only after trying to mount camera directly on tripod. The 70-300mm L lens is more compact than other Canon L lens with similar focal length, so some reviewers and Canon reps have commented that the mount ring is not necessary. Found the camera too front-heavy without ring. So what I saved with $ rebate on lens; I needed to spend it on this overpriced ring. Prefer to have Canon bundle this ring with lens and charge slightly more, and be transparent with consumers that the ring is necessary.

Rated 3 out of 5 by from Necessary Evil..... I think the lens needs the ring, however, why a large L lens needs you to spend $ more for it I don't know.As well, it is not as smooth as other rings on the other long L lenses. And I feel if I rotate a lot, I will remove paint from my lens.I am a very dedicated Canon guy, however this is the first item I am not completely satisfied with.However, B&H is Da bomb, and got the order to me ASAP.... As always!!!!

Rated 4 out of 5 by from Tripod Mount Ring C For 70-300mm I prefer to have the weight of the camera and lens balanced over the tripod. This does just that. I also like to have the ability to rotate the lens from the horizontal to vertical which this does. The only reason I did not give this 5 stars is the expense. I have used the cheeper Vello counterpart, but it just doesn't rotate as smoothly. In my opinion, Canon should include this with the lens.
