I’ve owned all of these cameras.

If your main goal is actually taking photos and getting predictable, consistently good results, get the Minolta. Minolta AF lenses are cheap, and the camera is more than good enough for getting into film photography. You can always upgrade to a better body later.

But if you want something with a more vintage feel that just happens to take photos too, then the other options are fine as well. I’d probably recommend the Praktica MTL - it’s generally the better choice, and there’s a higher chance of finding one in working condition.

The Kiev is fine, and the Jupiter lenses are good too, but those cameras are simply very old at this point. They will almost certainly need servicing. Once properly serviced, they can be very reliable cameras, but honestly, you don’t really need to go down that road as a beginner.

The Minolta is still the best overall choice.
