I own both the 50mm and the 85mm f/1.8 primes, and I find myself using the 85mm about 95% of the time. It's an amazing lens, and the FoV seems to be perfect for portiats on a x1.6 body.





It can be tack sharp wide open if you manual focus, but after f/2.8 you can do whatever because it's razor sharp after that.


Here's two examples of mine; one stopped down a bit, and the other wide-open.





Canon Rebel XT 350D, 85mm, F/3.2, ISO200, 1/800sec








Canon Rebel XT 350D, 85mm, F/1.8, ISO1600, 1/1250sec








All in all, I highly reccomend the 85mm over both the 50 and the 60.
