Ooh, this lens has a bad reputation everywhere I've read anything about it. >I now own the AF 2.8/105 EX Macro, which is excellent and only EX lens I now >have. I have the Sigma EX 300/2.8 and it's outstanding in terms of both optical quality and physical construction. The OEM 300/2.8's are supposedly better wide open - I've never done a comparison but I don't doubt it - but when stopped down to f/4.0 or smaller this is one sharp lens. -- Mark Roberts Photography and writing www.robertstech.com
