I'm trying to decide whether to buy the 85mm f/1.8 or the 50mm f/1.4. I assume both have roughly the same the same image quality, so the main difference comes down to the usefulness of each lens (I want it to be a lens that I use regularly). I want to use the lens for portraits and as many other uses as possible. I'm thinking the 50mm will have more uses since indoors the 85mm will probably only be able to capture head and shoulder shots. On the other hand, the 85mm will probably be more useful outdoors (soccer, volleyball, concerts) and well as larger rooms indoors since I can stand farther back. Anyway, my main question is whether the 50mm on a crop sensor provides the same face-flattening AND bokeh as the 85mm on full frame. Since the 50mm on the crop sensor has roughly the same FOV as the 85 on FF, this means that I would stand roughly the same distance from the subject for a given shot, which means the perspective/bokeh should be the same right? Any other advice/experience of these lenses on a crop-sensor would be greatly appreciated.
