I'm merely weeks away from my first expensive lens purchase which will be a telephoto zoom.
The reason for this is because i own a very very crappy sigma zoom. It is soft trough the entire focal range and only becomes decent at f/11.
So what do i use it for? Typically birds and the such...but i have made a semi commitment to myself and my former coach to take pictures for the football team next year. These are highschool games so they are friday night. The fields we play at are fairly well lit considering...but i just question if the f/5.6 of the 100-400 will be fast enough. Deep down i know it wont be, but the added price of faster zooms is an annoyance as well as the smaller focal length.
I'm mostly refering to the 70-200 f/2.8. I know it's a great lens both because of it's speed and more so it's sharpness, but it is only 200mm and i question if i will miss that 200mm once football season is done.
Another thing to think about is that focal length on the football field. I will have as much access as i'd like with the exception of stepping over the white out-of-bounds line. I took my 300mm sigma to the field a few months ago and was suprised at how much 300mm really is when your on the field.
So in that aspect i'm not too worried about 200mm.
I really have to question thoug hif the 2.8 is absolutely needed with typical football highschool lighting, and a 550EX flash.
Depending on how much money i end up making in the next few months at work i may just spring for the 120-300 f/2.8 sigma...but thats pretty much a grand over what i would like to spend, which is a lot of money for someone who does this for fun.

you may find yourself with one player properly exposed (probably the closest), and the rest just shadowy figures.
