All around lens - opinions

The Tamron 17-50 is a great lens. The constant 2.8 is handy...my only knocks against it were lack of IS and the lack of USM.

Is the AF that much slower than USM?

For general walk around use are you finding the 17-55 sufficient in reach?

Check it out yourself. Spend a day shooting with your 28-135 but limit it to 55mm. See if you can live with that. When I use my 24-105L, most shots are taken at 55mm or less but now and again I use its full length. I can't ever see me buying anything longer than that though.

I'm a big fan of the 24-70, it's on my camera more often than not. Heavy, yes, but the IQ is fantastic. Whether it is wide enough for you on a 1.6x crop body is something you need to weigh up though.

In lowlight, yes....it wasn't too bad when I had planety of light.

I was thinking this could be good, but read a lot of coments on here about the quality issues...
