SmallRig L-bracket.
Pros
Very very well machined, this will out live the camera, easily.
Cheap, I got it with 50% off pre-order for £25.
Keeps tripod mount centred to camera
Comes with tools.
It is Arca Swiss plate compatible, both horizontal and vertical.
Access to battery door
Cons
It needs tools to use, the Allan Key is held on by magnets but I feel it'll most likely be lost day to day shooting.
It's heavy, it adds a noticeable weigh to the camera.
The pinky "section" seems to stick out front he contour of the body a bit more.
More slippery than the leather half case.
How do I compare it to the Lim's Leather case? fantastic L-bracket, it is much better than those £20 L-bracket you find on Amazon solely on the tripod mount alone without mentioning the build quality. It is machined accurately, to the point it allows for the little strap triangle to stick out.
Although right now I prefer Lim's leather case as I am used to it's texture.
