First of all, I wasn't looking for an EF-S 70-200...I am looking for an EF-S *equivalent* to a 70-200 that matches up to the 17-55, the way the 70-200s match up to the 24-70 L. The 17-55 has a field of view similar to a full-frame 28-90 lens...an EF-S 50-150 would have a field of view equivalent to a full-frame 80-240, and I suspect a high-quality EF-S 50-150 f/2.8 IS USM wouldn't weigh much more than a 70-200 f/4. That's a lens I'd pay a lot of money for, if I had money to spend on camera gear
