I have heard it is just short of L type build quality...
I have heard the complete opposite. I hear it has 'L' IQ, USM, IS, but the build is cheapish. Not fall apart cheap, but you'd expect more from a $1k lens. I am in this exact situation, and would like to hear some objective opinions. I know it is difficult when you own and love something, and it is equally hard when you have been burnt by a piece of equipment and loathe it.
I really thought of just getting the Tammy because if it is optically close to the 17-55 then I can forgive no IS for the FL, but the AF motor has me worried. I love USM and am not sure I can buy a lens without it unless it is a full manual lens to begin with. I have never used the Tammy and unfortunately my local shop does not have one and neither do any of the photogs I know. I have used the Canon though, and I was not impressed with the build at all, but the IQ and AF it provides is spot on.
I want to hear some honest opinions, because my entire idea of lens selection hinges on what I choose in this FL range.
