The standard criticism of this lens revolves around (a) corner softness wide open, and (b) CA issues. But unless you're in the habit of putting your main subject in the corner in a low-light situation where f1.8 counts, the sharpness issue is moot; this lens if plenty sharp in the center wide open. Similarly, unless you're shooting landscapes in daylight at f1.8, the CA "problem" never arises.reviewed December 24th, 2009 (purchased for $475)
Great lens, particularly for folks looking for a normal lens on an APS-C frame. Dead-bang AF accuracy - and great speed - at all settings. Blows away focus-troubled products like the Sigma 30mm f1.4.
