So what all do you need to make these lenses work? It's simple... An adapter. Which one? Well, it depends on your aesthetic, me personally I tend to stick with Fotodiox and Fotasy, they are cheap and well constructed. Some people opt out for really high-end ones, like the Metabones Speed Booster's (which add an extra stop of light and reduces and crop that may be applied to your lens), but for me that kind of makes the process counter-productive. I buy vintage lenses because I get solid optics, for a low amount of money, so my advice to you is to pick up a few cheap lenses, pick up a few cheap adapters and experiment before you go all in.

What else do you need to make these lenses work? Patience. You really have to use your focusing skills, you have to understand when to step up from f/1.4 to f/2 to get the eyes in focus, don't get romantic about how wide your lens can open. If you guys have any other questions about vintage lenses, let me know, with that being said here are few lenses that I recommend you guys try first. On the left are street photography lenses (wide angle) and on the right are portraiture styled lenses (tele lenses).
