This lens is a must have ..... Nothing more to say than all the other comments about the quality. Weight, yes, but everything feels quality. I have various goals including a 105 macro 2.8. I keep it, I liquidate other to add to the 70-200, a 14-24 and a 24-70 mm. Given the quality of the first, the other will cover all my needs with quality "pro" including fixed focal lengths.
