My kit consists right now of 3 zooms that I consistently use. The 10-22f3.5, the 24-70f2.8 and the 70-200 f2.8. My primes are a 28mmf1.8, 50mmf1.4, 85mmf1,8, 100mmf2.8 macro and 135mmf2.0L and the 1.4tc. My next two will probably be the 200mm f2.8L(best prime value out there IMHO) and the TS-24mmf3.5L. (Maybe not a true prime in the purist sense of the word, but it looks like a really fun lens) I really love primes. Except or long glass, this pretty much allows me to shoot anything I want. I am working toward the 400mmf2.8 for sports and wildlife.
