2pcs Quick Release Plate Tripod Mounting Plate for Camera Mount with 1/4 3/8 inch Screws Manfrotto MVH500AH 501HDV 503HDV 504 701HDV MH055M0-Q5 Innorel f60 Miliboo MYT802 RC5

Just what I needed for my Canon EOS90D.

Does not fit any of my three tripod heads. The shape of these plates is poorly designed. They don't match the Manfrotto 501 shape. See photo. The SmallRig plate is the standard shape—the same shape as every other 501 plate I own. The TOSICAM plate is obviously shaped very differently. It doesn't slide in the tripod head!

Fit good in my tripod

I bought a pair of these- intending to make swapping between my camera, spotting scope, and binoculars fast and easy. I also bought an "Avella Video Tripod Fluid Head with Quick Release Plate" to upgrade my tripod. Unfortunately, these plates do NOT fit the Avella head; they slide in partially, but bind up- they are too wide by maybe 1/16"...... Disappointed.

The shorter on allows me to get the battery out of my camcorder without having to remove the plate (as expected). The only thing that would have been a "nice to have" would be a paint mark on the side(s) to help setting the balance point. The finish isn't quite as nice as the original, but the plate works fine.
