I purchased this off ebay and, idiot that I am, I bought it for the wrong camera. Brand new in the bag and comes with an allen key.

It's supposed to fit an a7ii and a7R ii. I'm not sure if it fits any other camera, but it definitely does not fit the original a7. It's an RSS knockoff and it's compatible with my actual RSS things.

$10 firm

I'm located downtown in the evenings or at the university during the day.
