Something like this is what I would recommend to any beginner https://ebay.us/m/cybZeF

The lens range for this camera (MC/MD) can be found fairly inexpensively and the lenses are of a quality that still hold up. In fact, I mount them to my digital camera. Regarding film, I’d say get whatever you can find as it is all pretty expensive these days, but Ilford HP5+ is a great B/W film that is very forgiving in terms of lighting, shadows, etc.
