I use a 500 f4 with 1.4x most of the time and often would like even more. No matter what lens you use there are times when you'll want more reach. It's worth working out what you really want before spending your money. Unless handholding is a must then the Sigma 500 f4.5 would be worth a look. More reach and less cost that a Canon 300 f2.8, but you'll need to use a tripod to get the most out of it.</p></blockquote><p></p>
