Here's a picture of my Canon EF-M I got from a charity shop last week. When I picked it up I put a roll of Kodak 200 Colour film in it and it made a short winding noise and beeped showing nothing in the display.
This camera, like the 300x, winds the whole film out and then retracts the exposed film. I thought the battery must've died or had too little power left. I sent for more (2CR5) batteries. I put a fresh one in and turned the camera on. I got the same beeping and no display. So I opened the back.
It turns out that the camera had rewound the film I'd put in, maybe the charity shop or last owner had pulled a film out. It's my best guess at what might have caused it. After I retrieved the leader (first go) it loaded fine.
The split screen will be handy for use with adapted lenses. It just has the two dials on top. One for shutter speed and one for aperture with an A option on both so you can have either shutter priority or aperture priority auto.
Unfortunately it's another one on the list on 35mm Canon EF cameras my Yongnuo lenses don't work with. It's based on the EOS 1000
