When someone asks me a question about a camera via e-mail, it's can be easier to put together a quick video.
This is the Pentacon Electra. It's a 35mm camera that requires Agfa Rapid cassettes, which today you have to preload. Plus, you're limited to 12 photos.
The Meyer-Optik Domiplan has that swirly bokeh.
I tried to add some humor to this video.https://youtu.be/WZIZVoWmFj4
Here's the only shot that I was able to locate. My dog.
