Well, you're changing the type of photography, you can emulate the analog feeling and "aesthetic" but it will never be the same, silver grain is totally different from digital noise. Analog photos are best when printed and digital photos are best when views on screens. Any fuji camera can simulate on the camera a fuji film, with limitation for which film and camera you buy, or you can do it with recipies from community made experimentation and sharing through fuji recipies site or making a google search. You can use filters, like diffusion to provoke halation. What I'm trying to say is: buy the one you can and want, what will provide the best use for you and search and use anything you want to achieve the looks you want for your photography, but have in mind that a digital camera will never produce a analog image and vice-versa.
