Q: 1. Are the plates on this L-bracket compatible with Arca-Swiss Slidefix ? I am using an Arca-Swiss item 801213 (Monoball P0 Panning with slidefix QS)

A: Yes the arca-swiss plates would be compatible across all arca-swiss brackets or panning systems.

Q: 2. Arca-Swiss Cameraplate Index monoball Fix is compatible with a pin hole fitting Sigma sd Quattro? Thanks.

A: That camera is not listed as tested by Arca-Swiss. We have the opinion that there is a very good chance the locating pin will work.

Q: 3. What is the maximum width for plates that can be held in this device?

A: The plate must fit the dovetail slot in this Quickset Device. I've found that the Quickset lever won't lock unless I had a camera plate that fit into the dovetail slot properly. I use an Arca Swiss 802260 Monoball Fix 32 Camera plate (the B&H # on my order was ARSF32C) with the Quickset Device - there are other Arca Swiss Monoball Fix 32 plates available as well. I've measured the 802260's camera plates dovetail with calipers and at the 'neck' of the dovetail, its 19.07mm and at the base of the dovetail 25.85mm The height of the dovetail from bottom of the dovetail base to the bottom of the camera plate is 5.45mm. When the Quickset Device has nothing in the dovetail slot and the lever is in the closed/latched position, the opening is 23.04mm (this measurement is at the location where the camera plate's dovetail neck would fit. When I push the lever as far open as possible, the opening is 25.12mm wide -- but the lever won't close if you fit something this big into the Quickset Device.

Q: 4. Will this fit/work on a A7R3?

A: I am a photography enthusiast, recently bought this plate to mount my a7r3 with a monoball q0 ball head quick release system. It works good. I left it attached on the bottom of my camera. Sometimes I shoot handheld, the plate does not get into my way. Maybe because my supporting hand is holding the big lens, not the body.(sony 24-70 gm).

Q: 5. Will this work on an Arca-Swiss C1 Cube? (CLAARC1CC 8501003.1)

A: Yes, the Arca-Swiss monoballFix Cameraplate for Select SLR Cameras is compatible with the Arca-Swiss C1 Cube Geared Head with Arca Classic Quick Release.

Q: 6. What is the purpose of the pins? Why should I get this plate for my Canon 7D instead of a cheaper plate without the pins?

A: The pin, there is only one, simply assists to help place the plate accurately on the base of a camera i.e. parallel to the body. The plate actually has more holes for the pin, i.e. fits more cameras, than the diagram reveals but should suit your Canon just fine (though, caution, I use Nikon). However, it's not essential to use it and, at least in my case, the pin came separated from the plate. So, fit it or not. My reason for choosing this plate versus the other is its length. I want stability, so the more length the better, in my view. Aesthetically, on the Nikon, it sits/looks better too, than the square version does, but hardly a reason to drive a purchase decision, As for price, it's just a few dollars more, they are very close. I guess you pay for the extra length.

Q: 8. Will this work with the Arca Swiss D4 Geared Tripod Head Quick Set, Monoball Fix?
