Hersmay 120mm Arca-Swiss Quick Release Plate with QR Clamp Adapter with 3/8" 1/4" Screw Hole Compatible for Camera Tripod Ball Head Monopod

It is a great clamp and works exceedingly well for my intended purpose of giving stability to a long lens on a large ballhead.

I use this to mount an aluminum bar to my rifle for a chronograph. I needed an ARCA Swill plate adapter and this was perfect for the job. Mounts easily. Stays put. and is long enough to provide stability to the aluminum bar. Perfect for what I needed it for.

This feels like a very solid clamp! I bought this and a Sunwayfoto DDC-110L ($85), and I'm not sure whether I can justify the enormous price difference to keep the Sunwayfoto clamp. That one is nicer, period, but I'm not sure it's any more functional. This one clamped down tight on everything I tried except for the Desmond 80mm x 60mm plate, but that plate didn't fit into anything else either.You do need to use longer plates and keep part of the plate across the center of the clamp. If not, the clamp bar pivots out at the screw, which I'm sure puts a lot of stress on the screw. This is true of all long Arca clamps, though.My only hesitation with this is the lack of reputation and fact that I don't see how to take it apart easily to inspect the internal workings & materials. I trust Sunwayfoto to not let my equipment fall off the tripod or jib. I just don't know about this brand.

The Clamp is fine considering the price point. It fits my Video Head perfectly allowing me to mount my Tamron 150-600 G2 Lens on my Video Head now. Unfortunately the clamp doesn't open wide enough to drop the foot on the lens into the clamp from the top. It MUST Slide in from either the front or back. That's unfortunate because in order to do that, I have to remove the safety screws from the foot of the Arca plate on my lens. Not something I'm happy about. Looking into a way to modify it to open just a mm or so more (without screwing it up) Otherwise it'll do what its intended to do and do so at a fair price.

Wow! I love this product. I attached it to the top of my Movo MTP-11 purchased at Amazon here https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=Movo+Photo+MTP-11+Motorized+Panaromic+Time+Lapse+Tripod+Head and it works perfectly. It supports my Nikon D750 camera and lens with no problem. I simply can not believe the quality of this product and the terrific value. Whew.......I can not rave about this high-quality low-priced product. I will NOT put my expensive Nikon D-750 on something that will not hold up and believe me, this product DOES do the job. If you buy this product, you'll be glad you did.

I wanted to take an older tripod and use an L bracket, I am using the VariZoom fluid head tripod. This QR-120 mounts perfectly to the Plate of theVariZoom, I am sure that this would mount to any normal plate and screw set. I then added the Fotasy Universal L Quick Release Plate, I now have an Arca Swiss type L bracket on my Fluid Head. It works mounts fantastic. Tried it out with My Canon 5D and a battery grip and it works! Also allows for a cable release under the bracket.

The screw holes for mounting the plate are offset. They are not centered. If you want to use this plate with any rails, any camera lens supports, or any other equipment that requires your camera/lens to be centered on any cheese plate, SmallRig, or any other accessories it will NOT WORK. Even on a regular tripod or ball head the weight is off to the left/right whichever way you have it configured. In my case it's basically useless because it is off center, my camera lens support won't work, follow focuser - nothing is lined up. It would have been a great solution, and it is well made, however manufacturers need to realize we DON'T use these things for a single purpose! They are being sent back as unusable, and I will have to find something else. How hard can it be to center your mounting holes????

Works as it should. If I need another I'll get this.
