Analog film photography and cameras

Not sure what a "proper used camera" is. Are the low cost fixed focus consumer box cameras "proper"? Are my favorite Robot cameras "proper"? Are Rollei TLRs "proper"? Are modern electronic cameras with image stabilization and auto-focus "proper"? I would set the mark as "cameras that were trying to take good pictures" .

Then you had better define what a 'good picture' is. Or don't. Actually, please, please don't.
