First you say that the 70-200F4 is too slow, but then you list two lenses that are slower. Rather than the two you mentioned, if you are going for wildlife, get the 70-200F4L (Non IS).


with a 7D, the F4 is plenty fast, just like your 300mm.


If you want to buy more than one lens, buy a oder used 70-210mm F4. They can be had in the $100 range, and are a great lens at that price. They have the push pull zoom which is great for sports action. Then get the 35mm F2 and the 50mm F1.8 to go with it.
