...I'm not sure what I should do.
Me - I shoot mostly outdoor sports (running, track, softball, baseball, and horses) with my 40D & my 70-200 2.8 IS.
After renting the 100-400 and the 300 2.8 last year, I got my heart set on the 300 2.8 and started saving for it. I rented both a few more times in the last 12 months and I really love the IQ from the 300 2.8, but I also really love the reach/range of the 100-400 and I can live with its IQ (especially for most of the sports I shoot).
Last month, I stupidly rented a 1DmkIII for a weekend. DAMMIT. The AF is awesome, and my OOPF rate dropped compared to my 40D.
So, if you were in my shoes, would you:
1. Get the 1DmkIII now and start saving again for a lens; or
2. Get either of the lenses now and keep saving for the 1DmkIII.
Thanks!
