Best Tripod Lens Mount Rings in 2020

Elefront Tripod Mount Ring for Tamron 100-400mm F/4.5-6.3 Di VC USD (Model A035) with Built-in Arca Type Quick Release Plate Review:

I'm new to photography and a lens collar was something I didn't know existed or realize I needed until I learned my new lens was going to double the weight of my little DSLR. It seems a 3rd party collar for the Tamron 100-400 was non existent until a few weeks ago. Found this one on a whim on Amazon and was glad to be able to get it prime, arriving the same day as my new lens. Took me a minute to get it to fit right, but it fits snugly and I had it set up on my tripod last night without worry that my lens was going to warp my camera mounts or that the tripod would drop my glass. Happy so far.

FocusFoto Metal Tripod Collar Mount Ring 1/4 for NIKON AF-S 80-200mm f/2.8D F2.8 Zoom Lens Review:

Pro's; super handy as a handle or grip to support the camera. It works very well as a tripod mount. The price and quality is good and I'm sure it will remain on my camera for years to come.

Con's; the clamp is a little large for the Nikon P900 lens, I had to add a little material to the I.D. of the clamp to get enough holding pressure on the camera lens. Not that big of a deal because now I don't have the metal clamp contacting the plastic camera/lens housing. I used the soft side of some Velcro strips to fill the great. One thing you will have to add to your camera bag is a wrench to loosen the clamp should you want to turn your camera 90 degrees for a vertical shot (unless you are using a Ball Mount of course).

Elefront Tripod Mount Ring for Sigma 100-400mm f/5-6.3 DG OS HSM with Built-in Arca Type Quick Release Plate Review:

Not having a lens mount or an easy way to attach one to the Sigma 100-400 was one of the main concerns I had when buying it and I started to realize how important one would be to me because I shoot on a tripod a lot. I was pretty happy when I finally saw this, took a change, and so far it seems great. It has padding all around the interior and fits snugly around the lens. Once it's on it feels really solid and I don't have any concern about it not supporting everything properly.

A few notes:
1) When holding my fingers where I usually do on my Nikon DSLR they will rub up against the back of the metal mount, not a big deal but I thought it was worth mentioning.
2) I feel like the window for the focus position should be a little larger, the ends of the dial are cut off and because of the thickness of the material you can only see it when looking directly down at it. Again not a big deal to me.

DSLRKIT Tripod Mount Ring for Tamron SP AF 70-200mm F/2.8 Di LD [IF] MACRO Model A001 Review:

Feels solid, and I'm sure would work well for the non-VC 70-200 f/2.8. I took the risk and ordered for my 70-200 VC (Nikon) version and leaves the screw thread about 2mm shy of connecting and about 5mm short of safe operating length. So, I can safely say that it does NOT work for the newer Tamron 70-200 VC f/2.8, so alas, I must return it and order the Part #A009E-067 which I can also verify that as of the posting of this comment is ONLY available as a part directly through Tamron. #hinthint ;_)

JJC Tripod Collar Mount Ring Replaces Canon Tripod Ring A-2, for Canon EF 70-200mm f/4L, Canon EF 70-200mm f/4L is, Canon EF 70-200mm f/4L is II USM Lens Review:

The title of this review says it all - it is a copy of the first of 2 productions of Canon's Tripod Collar Mount Ring. It is a solid, steel collar and it does the job. The ONLY downside that I have found is that the inside lining of this $8 no name is cloth and not a rubberized material. The reason for a lining is, apparently, to prevent scratching of the lens when going for a landscape picture mode to a portrait picture mode - you can loosen the tightning mechanism to rotate the camera & lens. I use a monopod with a 3 way adjustable head which I use to change the picture mode, eliminating the scratching problem regardless of the collar mount being used. I've been using this no-name collar for 4 weeks (hundreds of pictures).

Also - the color of the collar is not a perfect match for the Canon lens I use (70-200 "L" series) and the metallic finish of the collar is just "OK" - but are these things all that important?

Save yourself a lot of bucks!

DSLRKIT Tripod Mount Ring B (W) for Canon 70-200mm f/2.8L is II USM & EF 100-400mm f/4.5-5.6L is USM Review:

Spent hours scouring the web for a collar for this lens. Can't even find it on the Canon website...had to call Canon parts for information.

Ordered this one only because someone else indicated it would fit this lens. They are correct. It is very similar to the collar from Canon for my Canon 70-200 f/2.8 IS USM. Differences are that this one is hinged, doesn't have the cut outs to slide on over the little lens bolts and color is just slightly different. BUT....
Color - could care less that it's slightly different.
No cut outs for the bolts - not a problem because it's hinged which allows for you open it up enough to put on over the little lens bolts rather than slide on like the Canon one does, and on the inside there is a grove wide enough to allow for the little bolts to sit in it nicely.
Added bonus is there are two tripod mount sizes vs. the Canon one which only offers one size.
There is no problem working the zoom ring with this collar on.
Paid $130 for the Canon one with shipping and sales tax, so I'd order this one again any day. Although the shipping was quoted as longer in my confirmation, I received in 10 days. Not too bad!

ZUCRQ OP-5 18MM Wide Angle Lens with Magnetic Structure Compatible for DJI OSMO Pocket Review:

dji osmo pocket come with 26mm lens, it's kind of narrow, when using it for selfie. unless you are use a selfie stick. otherwise you have to extend you arm as long as possible. it will make you feel so tired. this 18mm wide angle lens did help a lot. the wide angel will help to capture about 30% more content on the screen without using selfie stick. the lens is very easy to install, it's using magnetic to mount on the camera. but you need to turn on the camera before install it and remove it before you power off the camera. it come with a case, it's can store the lens securely. overall i did like this add on lens.
