Originally posted by powderhound2 I contacted Mark at Really Right Stuff about availability of a camera bracket. I have used them on every every dSLR I've owned, they're based on the ARCA-Swiss mounting system, and are fantastic products. He informed me that they have no intention of making a camera specific plate for the Pentax K-3, but after sending him photos of the camera bottom, he assured me the
BP-CS universal plate would work. I just received the plate in the mail today, and two minutes later I had it installed. Looks good, and should work great like all the others I've owned.
Thanks for posting which one you got, I've been thinking about buying one of their plates.
I also asked RRS if they were going to make an L-bracket for the K3 as I love the ones I've had for the K20 and K5. Got the same answer that they weren't going to make one for the K-3. I ended up looking around for a universal alternative as I wasn't willing to give up the L configuration. I ended up buying one from Acratech, along with their GP head (I've always hated my Gitzo head). The Acratech L-plate works fine with my RRS macro rails, which also works on the Acratech GP head. It isn't as good a solution as the custom-designed L-plate I have for the K-5, which I had a tendency to just leave on the camera. The Acratech L-plate has a knob on it because it attaches to a tripod plate which gets in the way if you are not using a tripod. Also, the Acratech plate that the L-bracket fits onto is a basic plate. The RRS plate you bought has something that I wish my Acratech plate had - a place to attach a connector for my Optech sling strap. Since I know that the Acratech equipment is compatible with RRS, I wouldn't hesitate to buy one, and I think that would be a reasonable alternative all the way around.
It's really too bad they aren't going to make the L-bracket for the K3, their stuff is so beautifully engineered and works so well.
