Hi guys, I've just created an account but I've been reading on this forum for quite some time now. It seems there aren't many posts about superteles so here I am, posting this question. 
I have recently grow an interest in sports photography in addition to what I do usually, which is landscape so I'm probably a complete noob in this area but I am stuck between a choice of lens.
First we have to exclude the new Canon super teles as they are EXPENSIVE!!! It's true, I can't afford them no matter how good they are.
So the choices, the EF300mm f2.8 L (non-IS version), the EF300mm f2.8L IS(first version), EF400mm f2.8 II(non-IS) and the EF400mm f2.8 L IS, all second hand of course, since they are all been discontinued. And if someone could give a comparison of the first generation IS super teles to the latest one on AF and IQ that would be fantastic!
Mainly for hockey, football, basketball and soccer. I already have the 70-200mm f2.8 so yea. Body I will be using will probably be a 1D IV I will use my 1Ds III if I have to......
Thanks for your help guys!
