I shoot with a humble canon eos m with a NIKKOR 50mm f/2 vintage lens. It produces this wonderful grain as if shoot on film. However, no auto-focus, plus the filter from NIKKOR to canon eos m lets in light. Does anyone know of any alternative type setups with more capable equipment? I really don't like shooting digital but I think that's because of my ignorance. I love to shoot documentary style and portraits which works so well with this lens but don't know how to recreate it?
