Fotasy 200mm Arca Swiss Plate, Quick Release Plate, Long Arca Type Plate, Tripod Quick Release Plate fits Arca-Swiss Universal Standard Clamp for DSLR Camera Lens Tripod Ballhead

This is a budget option that works. I have found som other cheap options where the threads did not go far enough on the screw making it impossible to tighten. These are fine.

No frills, affordable. Does exactly what it is supposed to do. Bought a replacement lens collar/foot for a new nikon 180-600. Very good fit. Extra room to find the center of gravity on a large lens. Solid on top of my Gitzo.

I recently bought a GVM (Great Video Maker) LED Ring Light for taking 4k video while documenting old dark buildings. The LED ring has the phone holder dead center which does not work with a large phone like a Samsung Galaxy Ultra as it presses the power button so I needed to make a custom mount. This Arca Swiss Plate in combination with a Manfrotto Universal Smartphone Clamp worked absolutely perfectly to move the holder over to better suite my needs with a large phone. It's very sturdy and holds everything secure. I highly recommend.

We bought a decent tripod that allowed for horizontal recording of arts and crafts looking down at a tabletop. We needed a small QR release plate compatible with the tripod that uses Arca Swiss style plates to attach the phone clamp. For our set up, I found that the 40 mm plate works with this tripod, https://www.amazon.com/gp/product/B088FPBXHH/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1, perfectly.From reading the other reviews, there was some concern regarding the two screw heads that protrude at the bottom of the plate. I've included photos to show how they fit on my tripod head. The protrusions measure about 2mm or 1/8". This keeps the plate from sliding out by accident and our tripod head has slots machined in to accommodate the plate protrusions and allow for minor slide adjustments. Also, the plate width was slightly different, but still fit the tripod head without issue. It's solidly constructed and a great value!

There's several listings of these 25mm plates with stop pins, I have ones from Bestshoot and Fotasy, and they all appear mostly identical with slight manufacturing fluctuations.There's also a few other 25mm plates with slightly different designs, some shorter, all without stop pins, but this isn't about them.These are well-made enough, good for compact applications, the main 1/4-20 screw takes a 4mm hex (or flathead screwdriver), and the stop pins are removeable with 2.5mm hex.The problem is finding a clamp that stays low profile and can take these plates as-is.So far I've only found two (at B07TPS89PR and B07W1CLXY5 if you know how to enter Amazon URLs manually) that I can personally confirm are close to the same width of the plate, hold these plates centered, and clamp along the entire side of the plate. Unfortunately, they've been subjected to Amazon Product Churn and don't seem to be available unless you dig around on more... direct-from-source websites.The fishbone style clamps don't have slots for stop pins, so they'd either have to be removed, or the plate has to be put in offset, with one stop pin in the clamp's screw hole and only part of the side being gripped. I don't like the sound of either of those.I've also gotten one of the very common 38mm clamps which look like they'll work, but the stop pin slots are too wide apart by literally just a couple millimeters. It is possible to put the plate in offset, one stop pin in the clamp's screw hole again, while still clamping the entire edge of the plate, but this is already getting too wide for some of my use cases.There are also some 25-26mm clamps on Amazon that look like they might work, but they're rather more expensive than the designs that I know work, and I'm not sure I want to bother with going through even more try-and-return processes.
