Used for over a year with a 40D (it was a kit lens) until I bought a 24-105 F/4L to replace it. To understand what you want from photography - that's it. Wide enough for landscapes, long enough for portraits. There was not always enough aperture, especially since at the long end the aperture is already at least 5.6. For an initial breakthrough - a very worthy lens. All the same, if you buy new ones, then elks.
