CANON EF-S 17-85mm IS USM: Digital SLRs Only! Pros: IS non-rotating filter mount quiet operation fast internal focus ‘lightweight’ constant length focusCons: Maximum aperture only f4 somewhat expensive no full-frame compatible sharpness below fixed lensThe Bottom Line: Certainly the most versatile lens to date for Canon’s dSLRs with weakness regarding sharpness and chromatic aberration.
