I have been saving for months to buy this lens, and now that I am in a position to do so, I am asking myself why. My current arsenal consists of a 10-22, 24-105 and a 100-400. I primarily shoot wildlife, some nature and landscapes and would like to do some macro. I especially like shooting birds, although my craft isn't up to Nates level YET. Generally, I have been less than satisfied with the IQ of the 100-400. The weakness in my current lens inventory is that I don't have anything that is remotely considerd "fast" or anything with outstanding IQ--hence, my desire for the 70-200 f2.8 L IS. Since I like to shoot at sunrise or sunset, I find the 100-400 lacking. Any wisdom from the forum members would be appreciated.





Thanks,


Bob
