I finally managed to snag a 5D tonight, which I have been wanting to do for a while. I love the 85/1.8 on the 5D, and the field of view of the 50/1.8 (but I'm ready to upgrade that one to the 50/1.4).
The 50 makes a pretty good walk around in many situations, but I need something with wider angle, and preferably a zoom as a do anything lens. I had the Tamron 17-50 for my 40D. I loved the range, speed, and sharpness, but I hated the AF noise and speed. I am a big fan of USM.
When I bought the 5D I picked up a 28-135 IS used. Since it is dark I haven't done a ton of shooting with it to see how images are, but reviews of this lens are good, not great.
I would prefer to have something faster, but I'm kinda hoping to avoid the noisy Tamron 28-75. Is there anything else I could get in that price/focal range with good focusing and good IQ?
