>>4368340I'm working on an 8x10 shot with it. Here is a very terrible shot of an egg carton I took with my 5dm3 attached to view camera before the batteries died and I could take a better shot. My setup was less than ideal because I didn't want to tear down my 8x10 camera to use my good tripod. Not quite in focus, and even with a 10 second timer the setup was still wobbling a little.
The level of magnification you can get with this thing is crazy. I believe the lens is optimized for 5-10x magnification, and this shot was taken around 6-8x.
