We mentioned yesterday that B&H had several camera plates for the Canon EOS 6D Mark II available for purchase (although most are on backorder at the moment). However, I forgot to mention a clever design feature of the Kirk L-bracket which allows full functionality of the 6D II's vari-angle LCD screen.
The L-bracket's side port features a pivoting mechanism which enables the side plate to swing out of the way of the LCD (shown in the video above).
B&H has the Kirk L-Bracket for Canon 6D Mark II available for purchase with expected availability in 7-14 days. Note that if you plan on using the BG-E21 battery grip with your 6D Mark II, you'll need to purchase the Really Right Stuff BG-E21 Base and L-Plate Component. In the RRS design, the L-plate can be removed entirely for full access to the LCD.
