I was on another 7D job today, and I finally had to consider how to do low mode. I have a practice cage that I've outfitted with a Bogen universal plate for the camera and a 5/8" rod to mount the motor (something sturdy enough to not push away from the lens when focusing on stiff lenses).

Of course, the way my top rod is mounted, it makes setting the dovetail to the top nearly impossible. I know how to future proof it so the option exists to go into low mode and camera be righted, but for today's purposes, I just went poor man's low mode.

The MK-V seems to bind the camera into either normal mode or low mode, and going between the two appears to require a complete rebuild. Some of them appear with only normal mode in mind, counting on poor man's low mode when needed.

by poor man's low mode do you mean flipping the image later?

the setup I built has a dovetail plate on the top and bottom. I posted it in another thread a couple of days ago, too lazy to re-post. People have asked me why I used nut caps instead of a lower profile design, and the answer is so I can set the cage on the ground and keep the bottom dovetail plate off the ground. Basically that setup allows me to flip it from high to low, the only thing that needs to be detached is one BNC video cable. From an editor's standpoint, I don't like to flip the image unless the orientation of the video is built into the metadata such as it is for redcode "raw". For more traditional video formats it isn't a lossless process
