## Description

desertcart.com : SmallRig Baseplate for Sony A7 V / A7R V / A7 IV, Bottom Mount Plate with Quick Release Plate for Arca, QD Interface, Anti-Scratch & Anti-Deflection - 3666B : Electronics

Review: Beautifully made base plate for the Sony A 7RV and A 7IV. - Superb base plate with built in ARCA tripod mount for our Sony A 7RV and A 7IV cameras. I purchased two of these. Very well made with trim to match the camera that protects the bottom of the camera and provides an ARCA tripod mount as well standard threaded sockets for other accessories. Fit and finish is superb and it is very easy to fit. A handy key which is magnetically attached to the underside of the plate is used to secure the camera and mount together. Once mounted it looks like an integral part of the camera. It locates without any adjustment and fits perfectly. One thing to note is that for access to the A 7IV battery door, there is a part of the base plate that swings aside. It will need to be closed when the battery door is closed. The A7RV does not need this for full access. There are no instructions so we had to work this out for ourselves. It is a minor inconvenience that you should note but it is well executed and does not look as if it will wear out over time. Pros: 1. Extremely well made. 2. Fits exactly. 3. Looks as if it was always part of the camera with matching camera leatherette finish around the edges. 4. Provides access to the battery (note the base plate piece that swings aside for the A 7IV). 5. Provides ARCA dovetail for tripods and machined sockets for other peripherals or tripod mounts. 6. Protects the bottom of the camera. 7. Very light weight. Cons: 1. Part of the plate swings aside to gain access to the Sony A7IV battery door that may not be obvious. Summary: Thoroughly recommended as a way to protect and add functionality to your Sony A 7RV and A 7IV.
Review: Perfect!!! - Perfect functionality for my Sony a7RV camera! It provides the grip and comfort I was hoping for. The camera feels more substantial in my hand. Great value for the money as it is very well made and well designed to fit perfectly on my camera! I highly recommend it!!!

### ⭐⭐⭐⭐⭐ Perfect!!!
*by M***R on October 23, 2024*

Perfect functionality for my Sony a7RV camera! It provides the grip and comfort I was hoping for. The camera feels more substantial in my hand. Great value for the money as it is very well made and well designed to fit perfectly on my camera! I highly recommend it!!!

### ⭐⭐⭐⭐⭐ Must have for A7RV
*by C***Y on October 17, 2025*

This is mandatory for bigger hands. If your pinky hangs off the camera, this baseplate gives it a comfortable home. I’ve seen reviews of people saying it’s too small or issues opening the battery door and I think they got sent the A7iii grip instead. The one for the V has been upgraded for the longer grip and has a part of the baseplate that folds out so you can open your battery door all the way without having to remove the baseplate. It’s actually a very simple, yet clever design. And for $30, this thing is hard to beat.
