So first, the hardware decision. Either of these two lenses.


1. 100-400mm IS


2. 70-200mm 2.8 IS with a 1.4 extender


So, who am I? This is my first real year into photography as more than just a hobby. I shoot everything. Sports, nature, portraits, weddings....whatever someone wants me to shoot, I'll be happy to do it.


I'm going to make up a SMALL amount of the focal range with the 1.4 extender. I don't want to do the 2x, because it degrades a little too much, and I will end up with both of these lenses eventually anyway, so I can use the 1.4 on the 100-400 and turn it into almost a 600.


Any suggestions from anyone?
