The 70-200mm f/2.8 is the the king of the hill in this area, but it's extremely expensive. A more budget-friendly and still very high quality option is the Tamron 70-200mm f/2.8, which I really like and highly recommend. You could also pick the 70-200mm f/4 which is lightweight, but I dislike the slower aperture. If the 85mm f/1.8 is long enough for your needs (and it probably is given your crop factor) is another outstanding option if you don't mind the inconvenience of a prime.
