Title: L class?
Review: I had this lens for a short period of time and experimented with various subjects. My impressions: IS works very well. 2.8+IS+highISO = flash-free handheld photos in the dark. A little too bulky and heavy for my taste -- I have been spoiled by the versatile and light 50mm 1.4 :) Zoom range is very versatile. This may well be the ideal tourist lens as it covers the needs for indoors, architecture, landscapes, and portrait shots.
