Re: 15-85 or 17-70

I own the 15-85 and used it a lot before I went full frame. It's a perfect range, but on the heavy side and slow (aperture). My copy is not super sharp, so be sure to test it if you get one.

The Sigma lens is approx. one stop faster, so I rented one. Yes, it is 2.8-4, but I found the IQ to be not so great wide open. I had to stop it down to the same aperture as my 15-85 to get acceptable results.

Good luck.
