Some people feel like the Blackmagic Cinema Camera & Blackmagic Production Camera 4K have the record button on all the wrong places. Movcam offers a wooden handgrip that conveniently adds a remote rec button.
The company Movcam has been around for some years and we see more and more affordable yet quality products appearing from them. Their newest addition, the Wooden Handgrip with VTR comes as a standalone, or together with a whole Blackmagic Camera Cage Rig that includes a second grip.
Right now all of these can be pre-ordered on the 16×9 Inc. page: LINK
