As an absolute beginner:
What is the best way to get started with Minox, which model would you recommend?
And how can I develop my films resp. which films are available on the market? Are there scanners for this film format?
Here is a very brief description, a detailed description on my website is planned, but I'm not there yet:
Which camera?
I would buy a Minox B. They are the cheapest because they were produced in the largest quantities and are the most widely available. Important: Don't mind if the exposure meter is defective. You don't necessarily need it with modern films. Costs $40 - $80
Which film?
For the first time, I would buy a ready-made Minox film. Spy Film from Blue Moon. Cost (in Germany): $26
Development?
For the first time, I would use the development service offered by the film dealer. You have to send the film in. Cost (in Germany): $6 + shipping Duration: 10 days.
Digitization?
You don't even need to try scanning, it doesn't work satisfactorily. I photograph the negatives illuminated from below through a magnifying glass. My simple digital travel camera is sufficient. The quality is so good that you can see the film grain. A digital system camera with a macro lens will certainly also do the job, but it's not necessary.
What could you do next?
Film: I cut my films myself from any 35mm film. From one film, 4 Minox films with 36 images each. Then you have the full choice at low costs. I use the Camerhack daylight slitter as a slitter. Cost: $35. You can reuse the Spy film cartridge you bought.
Development:
I found a photo lab nearby that develops the Minox films for me using the C41 process (but not black and white). Cost: $3 per film, 1 hour wait

It's worth doing some research in the area and speaking to the few labs that still make C41 themselves. I take the exposed film out of the cartridge myself and give it to my lab in a tin can. They then somehow thread it into their standard machine. That's definitely possible if they want. So speak to people in person.
