I love that lens! I want it! I just hope by the time I've got the money for it Canon may have overhauled it. We're 2 years shy of its 15th birthday! Personally I prefer a loud IS. Helps me make sure it's working. [img]/emoticons/emotion-4.gif[/img]



Especially since the IS on 300mm is not tripod sensing.


Even without an update, it is a great lens.
