I have stopped reading Pop Photo for at least two years, but for those that I read in the past, I can't remember any poor lens reviewed by them. My advise is, if you have other choice, stay away from Sigma. If you want a decent 300mm, go for a prime 300mm. regards, Alan Chan _________________________________________________________________ Join the world�s largest e-mail service with MSN Hotmail. http://www.hotmail.com - This message is from the Pentax-Discuss Mail List.
