[Arca-Type] Did the job perfectly that the part was manufactured for. Nice workmanship, very clean machining.

[0.115 lb] I've used a lot of QR systems, from Manfrotto, Peak Design, Falcam, and others. This is by far the best one I've used. I will be ordering many more of these. The main reason I bought it was for my gimbal. The problem with all the other QR systems is that they have a bit of play in them. This little bit of wobble makes them a bad choice for gimbals, as it can slightly throw it off the balance or just move a little in the middle of a shot and ruin the footage. This system is super tight, no play whatsoever. And yet, its even easier to take on and off than all the other systems I've used. I always thought PGYTECH was just a Peak Design copy cat, but on this one they beat them at their own game. Now I just hope they come out with more base options. I'd like to see one that you could attach the screw from the top, so I could rig the base to all sorts of cheese plate type stuff. Then I could use these for way more than just my cameras.

Also if you watch YT videos on this, you'll hear a very loud snap. I thought the snap might be too loud for me, as I do weddings and sometimes need to be extremely quiet. The snap is some what loud when there's no camera or stand connected, but as soon as there is the sound is absorbed and the snap is very quiet. In fact on my heavy fluid head I though something was wrong because I couldn't hear the snap at all.

[Aluminum] Two adapter sizes in one Arca-Type Plate
The best solution

[1x 1/4"-20 Male] Best quick release I have used to date.

[1x 1/4"-20 Male] I bought this plate to use it on long lenses when mounting on tripod. Plate doesn't require any tools and can be mounted in seconds.
Works very well with long and heavy old Nikon F-mount lenses attached to Nikon Z camera via FTZ adapter.

[0.115 lb] This SmallRig Arca-Type quick release plate lets one mount optical systems with either 1/4-20 or 3/8-16 mounting threads. In the case of my Tamron 300mm f2.8, I can even use both for a really secure connection from lens with camera to tripod. If you do not have a quick release plate on every piece of equipment with tripod mounting threads, standardizing on this item will mean that you always have the one you need.

[Arca-Type] I use this model plate on my Nikon D40 on an Arca Swiss Z1 ballhead with a handscrew plate mount. I previously used a generic plate with no lip on the back, which was fine for landscape shots but terrible for vertical ones. The problem was no matter how much I tightened the screw holding the plate to the camera, the camera would rotate a bit on the plate itself, making it very hard to compose shots on the tripod. I bought this plate because it has the lip in the back to prevent that. I've taken it out several times now, and it's worked flawlessly. The only thing I don't like is the allen wrench screw because I'd like to be able to put the plate on and take it off more easily. (My old plate had a simple flathead screw big enough that I could use a quarter to screw it in tightly.) But this plate is small and light enough that I always keep it on the camera, and the allen wrench fits in my camera bag anyway.

[4 x 3.2 x 1.2"] I've never had a problem with SmallRig items. I should have got this with the Quick Release base plate but I thought I had one that fit so wound up getting each piece separately. Very happy with this and the other SmallRig pieces. Can't go wrong with them.

[0.115 lb] fits perfectly, light weight

[0.115 lb] I purchased this along with the Moment Multi-Threaded Cheese Plate Mount with MagSafe as a versitle solution for mounting my iPhone 13pro on a tripod in either a landscape or portrait orientation.
