I was inspired by the Pixel 7 Pro Microscope mount to modify/remix it for the Canon 5D. As all Canon 5D users know, the camera doesn't utilize the LCD screen as a liveview.
You can simply slide this over the Canon 5D Classic viewfinder and set your pixel 7 camera to 2.5 zoom to use it as a makeshift LCD screen.
The original microscope mount was designed for a pixel 7 pro, this is modified to fit the pixel 7 not the pro. However, it is easily modified in orca if you want to change it. It's not a perfect fit but still stable enough for use. the mount works with a 1100D that I own as well, but the centering is off a bit.
In the future I plan on creating a clamp of some sort to make sure the phone doesn't slip out.
The author remixed this model.
This was modified to fit on the Canon 5D classic viewfinder. The Scope guides were removed and a Canon 5D viewfinder guide was added.
