This Rotatable Horizontal-to-Vertical Mount Plate Kit for Sony Mirrorless Cameras from Smallrig is a faster and more versatile alternative to using a conventional L-bracket to mount select Sony mirrorless cameras to a tripod head. This lightweight rotating mechanism allows camera orientation to be changed with the flick of a wrist, then locked in place with a large, ergonomic knob. The plate mounts to the base of the camera, leaving the sides and back uncover for full access to the ports and LCD screen. The base plate also allows full access to the camera's battery door. The lens release button makes it easy to change lenses without having to remove the camera from the mount or the tripod. The versatile mounting foot is compatible with both Arca-type and Manfrotto RC2 quick release systems.
- Quick Horizontal to Vertical Rotation
- Arca-Type and Manfrotto RC2 Plate
- Full Access to Ports and LCD Screen
- Two-Point Locking System

SmallRig 4148 Reviews
Lasted 2 Months
I got this because most of my clients as for both horizontal and vertical shots, and to be honest, I was very much pleased. However, after just two months of use, it stopped locking in vertical mode. It has a bit of a dangle which is enough to make it move and not be in full vertical mode. I tried seeing if something was broken or off, but I guess it's just not that sturdy or well-made. I'm honestly disappointed in this product, because it was promising.
NOT compatible with the a7R V
First, the baseplate screw is too long for the R V's shallower socket. I was able to fix this with a washer (not included) placed between the screw and the mounting plate. The larger issue is that the collar's lens release button keeps the body's lens release slightly depressed, preventing the lens from locking into the mount.
Sony a7r must have
I work with Sony a7r 5 mostly on a tripod, copy stand or mono pod. Let's face it with any of the G lenses this camera is too bulky and heavy to hand hold most of the time. Once we're on a tripod the tilt movement can be limited and even if not the rotation is pretty far off axis. The rotation allows for fixes of both of these issues. The 70-210 lens I use has a collar and it is really convenient. Well now I've discarded it (saving space in the bag) because the Small Rig works for all the lenses. This is a nicely made piece. Not too heavy or too light. Just the right weight to do the lob. Because of its dual attachment points to the camera body it makes for a more secure connection than any single point connection arca plate. No rotating or slippage when you sling the tripod mounted camera over your shoulder. It does add a bit of bulk to the camera rig, but it's worth it. Best accessory to come along in a long time. And all for under a hundred bucks!
The little rotating rig that could.
I didn't expect much at this price and was skeptical. Pleasantly surprised ... very well made and extremely well thought out from an engineering perspective. Allows rotating my A7R-IV camera from landscape to portrait orientation quickly and while keeping the lens centered the same ... I use it on a tripod especislly wityh a macro lens, and a monopod when doing location portraits. If Really Right Stuff made this, it would be 3X the price.
Important advantages over L-brackets
Until now I've relied on Kirk L-brackets. However the pivoting screens on the a7iv and a7rv are more easily used with this new rotating plate. Most of all I appreciate how much better control I now have on ball heads with the arca foot forward and thus closer to the center of gravity of the camera + lens. This is excellent with longer lenses lacking tripod collars, such as my Sony 2.8/90 macro and my Tamron 2.8/70-180. Today I was in the field doing wildflower close ups using a monopod close to the ground. Monopods don't stand by themselves. With an L-bracket on a monopod, switching from landscape to portrait is awkward. Position, framing and focus are lost in the process. But with this rotating bracket I could loosen the friction control with my left hand and rotate the camera with my right, while continuing to view my composition through the EVF. Access to the electrical ports is unobstructed, nice for in camera USB-C charging. To stabilize the bracket against horizontal rotation there is an anti rotation pin which must be screwed through the bottom plate to enter a matching hole in the bottom plate of the camera, alongside the battery door. My first Smallrig bracket was delivered missing this tiny part. B&H exchanged it. Be sure to use the pin. When not using a tripod or monopod this rotating bracket looks clumsy. However the Arca foot can rest in my left palm with the camera balancing well, thus facilitating steadier camera control and less muscle fatigue.
Won't balance on ronin
I brought this to use with my ronin, a7siii and prime lenses. I use the 55 Zeiss 1.8 and the 35 Sony 1.8, unfortunately both lenses are too light to balance on a ronin. I'm not sure if I need a different ronin baseplate but the placement of this rig puts all the weight on the back end so there is no way to balance your set up if you don't have a heavy lens. Hope this helps for my people purchasing this for their ronin.
This Mount Changed My Whole Process
I have struggled with L-brackets for years - forgetting them, changing them, losing them . . . Now, with the SmallRig kit, I struggle with none of it! I put the rig on my Sony body, and I just leave it there. It is light, unobtrusive, and easy to use. The design lets me get to my SD cards, my batteries, and all the side plugs without removing the rig. My favorite part is that, with a simple twist of one knob, I can rotate my camera from horizontal to vertical and never take it off the tripod. What a fabulous design. I am also grateful to the really lovely tech guy who helped my select the SmallRig (I came in for another brand that turned out to be not as sufficient for my needs). He got both brands out, helped me assemble and understand them, and was patient the whole time that it took for me to decide on the SmallRig. Thank you!
Convenient but restricts lens choice
I have used this for several months on an a7Rv. To use it securely, to keep it from rotating on the camera body, be sure to fit the tiny threaded antirotation pin into the matching hole on the camera base by the battery door. My first sample from B&H was lacking this pin, and was replaced. The good: 1. Speeds switching from landscape to portrait orientation on tripods. 2. Improves balance on tripods when using longer lenses. I appreciate this when using my Sony 2.8/90 G Macro and my Tamron zooms (70-180 & 28-200) 3. No interference with access to the USB-C port on the side of the camera, which I sometime use for charging during travel. The bad: 1. Blocks access to aperture rings on Zeiss Loxia lenses and on the Laowa 15mm f2 Zero-D. 2. Will not accept the newest Tamron lenses which have a protruding USB-C port. (I do not yet own such lenses). 3. Will not accept Sony teleconverters (not in my kit...yet...but maybe soon for the new 70-200 f4 macro). I've returned to my a7Rv specific Kirk L-bracket since I wish to use my Loxia 21, Loxia 35, and Laowa 15 Zero-D. However for anyone using only Sony lenses (without teleconverters) and only Tamrons not having the USB-C port, I do recommend this Smallrig rotating bracket, for the better balance and the convenience when changing orientation, on a tripod.
