Your tests have been very informative to me, as I am in the process of determining which lenses should I get. I am currently able to afford 2 lenses, as the first 2 lenses I have ever purchased (I own a canon 30d that came with the kit lens), I am trying to decide on primes, wide zooms, and telephoto zooms. If you were to only have 2 lenses starting out, which would they be? I either want to get a 24-70L or a 16-35L, and maybe a 70 - 200 2.8 though I find the 35-350mm intriguing and found a good deal on ebay. Opinions?
