Finally committed to the idea of selling my Canon 70-200mm 2.8 II and getting the Canon 135 f/2. I love primes and i wasn't using my 70-200 to justify having a lens of that caliber sitting in my bag. It wasn't that the lens wasn't producing great results because it was, just preferred the size and weight of the 135. So i sold the 70-200 and picked up a 135+17-40 and still had some money left over for an 85mm f/1.8. I second shoot for a wedding photographer and this past saturday was my first wedding without a 70-200 and honestly i didn't feel like i was really missing anything or unable to get shots i could with the 70-200. The 135 is awesome as well as the 17-40. So far so good!
