Plate for an A7R III

Hi

I bought an A7R III and I use Arca-type plates and clamps.  I checked a bit and...

The specific large RRS plate is, well, very large (the entire bottom) and according to reviews doesn't allow changing batteries with it on. They don't have a regular plate for this model.
Kirk only has an L-plate for this model which I don't want. They have a universal plate that supposedly works for this model but is not specific to it.

For my older camera, I had a specific plate, somewhat larger than a basic plate, but not anywhere near the entire bottom, with a slight curve so it doesn't rotate (which made it specific to that camera model).
Anything similar for an A7R III?

Thanks

I have the RRS plate/L bracket and really like it. Expensive yes but it fits great, looks great and very easy to change the battery.

Re: Plate for an A7R III

I use a universal Promaster bracket that allows me access to the battery.  The drawback is it is not adjustable while on camera to always allow enough room to the Sony micro port on the side of the camera.  It depends on the shape of the cable.  It was only an issue for my remote shutter release.  USB-C is not an issue.  The bracket was about $50 at my local dealer.

Re: Plate for an A7R III

Hmm... I read reviews on B&H and there are quite a few that claim they can't open the battery door with it. I'm wondering what's the difference? Maybe the design was changed at some point?

Even if that wasn't an issue (and I'm not sure it isn't), it doesn't matter if it looks good and it's not a matter of price. I don't like that large plate that covers the entire bottom.

Thanks

Re: Plate for an A7R III

Thanks, but I only found a Promaster L-bracket. I'm only looking for a plate (not an L-bracket) that is anti-rotate (i.e. not just flat like a regular plate... which I already have).

Re: Plate for an A7R III

Do you mean a normal 40-50 mm plate won't work?

Maybe I don't understand the question.

You need to transfer the battery door from the camera to the plate. The battery door and plate were designed to support this - no tools required. Easy to do and I has worked very well for me.

Re: Plate for an A7R III

I bought a cheap rss L bracket and they supply a hex key so you can take off the "L" part.

As Donald said regarding the RRS bracket, the vertical piece can be removed from the Promaster bracket as well.

my other issue with my bracket is I use several Peak Design products and the bracket obviously won’t work with or wasn’t designed to easily work with some of those.

I just drilled a 4mm hole in the side of my bottom plate so the clip could attach

Re: Plate for an A7R III

Smallrig do one for the RIII. I use one on my A7III, no need to remove battery door and the allen key for bracket removal\install is magnetically held in the base which i like. Also the L part of the bracket is adjustable, but I do have a slight problem plugging a remote in the micro usb port. Havent tried using the usb-c port yet

Thanks, I guess those reviewers didn't know that

I use the Smallrig with the A7R3 and it is great. I attach the Peak Design connectors, one to the lug on the camera, the other to the Smallrig base. This allows the camera with the 24-105, my most used lens, to hang with the lens angling in towards me which feels like the most secure way to carry that camera/lens combo on a strap. The connectors allow fast removal of the strap when I don't want it in the way. The Smallrig gives fast horizontal or vertical locking to an arca plate that stays on my tripod head. The build of the smallrig is excellent, it's much cheaper than the RRS and you dont have to change the battery door.
