Highly recommended!

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.

Ellis Vener (Atlanta, US)
More versatile than most L- playe brackets and fits like a glove

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.

Perfectly Fits My Needs

The quality of this L Bracket is beyond reproach. The onboard hex key storage ensures that I always have the tool I need to adjust the L bracket to suit my needs. The cables on the left side of the camera are easily accessed. This is the best L bracket that I have ever used. It puts the SmallRig L bracket on my A7RIII to shame! You can always count on quality and the right features at an incredible price from ProMedia Gear.

Love this bracket and plate combination. It gives a pleasant handling option along with holding the boomerang flash which I love. Promediagear tends to details in their products and this is L bracket/plate is no exception. Expertly constructed. Made in the USA with quality.
