Which prime lens is actually the best for Nikon DSLR portrait work because I'm totally torn. Ive been looking at the 85mm f/1.8G because the bokeh looks incredible online but then I keep seeing people say the 50mm is better if you dont have a ton of space to move. Im shooting my sisters engagement photos at a local park next month and I have about 500 bucks max. I want that professional look but I dont want to be standing a mile away from them to get the shot. Is the 85mm really that much better for the background blur or should I just go with the 50mm and save some cash...
