Look for a 80-200 2.8L lens used. I swapped my 70-200 4L with this and though it focuses a little less faster, I have been very very happy.
I was out shooting today at the park while I went out to swing dance, and these are couple shots with this lens, wide open: http://www.zuga.net/forums/showthread.php?s=&threadid=9092 and http://www.zuga.net/forums/showthread.php?s=&threadid=9090 If you really need 300mm, get a 1.4x extender with 70-200 4L or get a third party 1.4x extender for the 80-200. YOu will have sharper images, and a much better lens. 70-200 4L is one of the best values for money, imho. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
