Did someone call my name?
Even with my use of the 18-135, I have no idea if someone else needs it. Given that I have a DA*60-250, I wonder if I wouldn't be happier with the 16-85. Using my Sigma 8-16, I take an awful lot of images at 16mm. But I also take a lot of images from 85-135, almost 30% if memory serves me well. Sounds like the OP does a lot of shooting indoors, and the 18-135 isn't the best for that. I kept reading "no sun", well the 18-135 is a sunny day lens. The OP might be dismissing it, just for that reason.
Personally, for low light... sub 2 primes or the Sigma 18-35 ƒ1.8 are the way to go. ƒ2.8 just ins't that much different from ƒ3.5, and the 18-135 goes to ƒ3.5 at 18mm. At 24mm it's still ƒ4. My 50 is ƒ1.7, and my 35 is the DA 35 ƒ2.4. I own the Tamron 17-50 but I hardly ever use it. The primes are just so much better as low light options. Or to put it another way, for low light, my 50 and the Sigm 18-35 are as much better than a 2.8 lens, as a 2.8 lens is better than my 18-135. IN those situations, ƒ2.8 seems a little half assed. Why not go all the way?
