So over the last couple of months I have beat this topic up and I am finally ready to make my purchase! But here is my delima I really want to get the Canon 70-200 f2.8 is usm I verison lens. I believe retail is $1899 and probally can get it locally for 1699 to 1799. So to my problem, for that much money I could settle for the 200mm f2.8 (which I think is a little sharper) and the 300mm f4 (which I really want to get in the future). I dont have any lens that has IS so I think the 200mm f2.8 would be a great lens but would I be kicking my self for not getting the 70-200 in the future??? I currently own the 17-40, 50mm,100mm, and the crappy 75-300mm. With the 200mm prime would I be really missing out on the 70-200? Also on a side note Im obviously not a professional and do not plan on using this for any type of business just addicted to nice glass.Thanks Again TPF!!!
