Ok first of all the dovetails are very close tolerance. Meaning that minimal change in screw rotation for a 90 deg rotation of the camera. Or if you have a quick change it will lock in place without an issue between rotations. That is a very good thing if you are as lazy as I am.
My mixed feelings come from the bad machining tolerance on the dowels that expand the upright portion for clearance. The one I received is very bounce and only with messing with it a lot did I get it to lock in place properly, but only in the shallowest clearance configuration. Its really a bad engineering design in my professional opinion. Given that the design requires closer tolerancing in the manufacturing arena in order to function correctly. My decision to keep it has been made for the first part I wrote. My use case does not require the wire clearance factor. In fact if this company made a fixed L-bracket for the A7R4 I would exchange it for that one.
In conclusion if your going to use this for all of its intended use purposes ide look for another l-bracket. But if your only going to use it locked in minimum clearance form you wont be upset. Dovetails on both rails are machined to a thickness +- .003 on the one I received. That's really nice if you have to rotate that camera often like I do.
These are very well-made L-Plates along with all PMG products. Many accessories, including cold shoe products, are compatible with all their brackets.
I switched from Chinese brackets to all my Sony cameras, A1, a7vi, a7r4, a6600, and my RX100vii. This allows me to use all PMG accessories on any of the
cameras as needed. Great products and wonderful service.
This is one piece of gear you can quickly install and forget it. Well designed and rock sold. I’ve had other brackets you have to carry a tool with you just to keep it tight. I appreciate the ability to adjust the vertical standard to make access to the side ports of the camera easy.
I have used Arca-Swiss quick release plates and L brackets from every major and quite a few minor manufacturers since the mid 1990s. I now use PMG products exclusively. They aren’t paying me or giving me free gear to say nice things about them but I chose PMG because of fit, finish, versatility, and price point.
Excellent no faults.
