SmallRig 2143 Reviews

Great Baseplate, but

By Dick
Rated 3 out of 5
Date: 2026-08-24

Most all SmallRig 1/4 in holes are spaced on 9mm multiples. This does not. The only useful mounting hole is the 5/8 in. This limits how you can mount this baseplate in your project.

Not ARCA-compatible!

By Todd
Rated 1 out of 5

This baseplate will not hold any of my standard ARCA mounts. SmallRig claims the clamp can be adjusted via the screw on the lever to fit "nearly all" ARCA mounts. This is deceptive.

Asked by: Riley
No, the Benro S6Pro Plates are Manfrotto 501PL compatible, and would not work with the SmallRig Arca-Type Quick Release Baseplate. I will add two Manfrotto 501PL options below. Axler QRA-501S Quick Release Assembly BH #AXQRA501S Falcam F50 Square Quick Release Base BH #FAF50SQRB

Is this compatible with Arca Swiss 3 Legged Thing L-brackets like the QR11-2.0?
Asked by: Keith
A staff member at B&H pulled both items from stock, and it turns out they ARE NOT compatible. as the sides of the groove are too thick for both the camvate plates as well as this SmallRig. Despite being adjustable for height of closing, it can't adjust for the thickness.

Can this be used to "drop in" to the QR mount from above the mount? Or does the plate have to slide into the mount from the front/rear?
Asked by: Caleb
most plates can drop in. The lever pulls the locking portion back far enough that you can drop in the camera from the top. I have several of these and all my plates will drop in.
