So I'm overhauling my lens lineup. Mainly i shoot surfing so that is the important thing for these lenses. Either I get the 100-400 and keep that on my body the whole time, or i get the 400 f/ 5.6 and the 70-200 f/4 non is and switch them dependent on the subject distance. The price factor would be about the same. I am shooting on a crop body.

Get the 100-400, the difference in IQ is minimal compared to the 400/5.6 IMO @ 400.

You also get IS and ZOOM in the 100-400.

The concern i was having with the 100-400 is its auto-focus. From the reviews i have heard it seem very slow. Also from theses review a common theme is that the "is" is not that great.

I've done a side by side of seagulls and aircraft in flight on a 1D2 and 1D3 body. The "Slow AF" is a little over blown. It's not lightning fast as the 300/2.8IS and 400/5.6 but it's certainly "usable".

Good technique helps. What kind of body are you shooting?

Max, if you are hand-holding any IS helps, 2 or 3 stops in the case of the 100-400L. If you're gonna shoot with a tripod IS doesn't matter, so you just need to decide if the extra range, one lens solution will cover your needs. If the reach of 400 is all you need the the prime might be your best bet, even if just a little AF will be faster and the glass sharper; I'd suggest you shoot from a mono or tripod tho, unless your long lens skills are rock steady...

70-200 f4L's are fantastic lenses, I have the IS version, it's my most used zoom!

You dont need super fast AF for surfing. Distance to surfer doesnt change that rapidly.

Though if you want to freeze motion your probably looking at shutter speeds so high IS wont have much affect (unless panning).

I shoot radio control events & the 100-400 can lock onto planes traveling much faster than the surfers you'll be shooting. The AF system in the body will be the weak link until you upgrade to a 1 series, 7D or 5D3.

I found the spot AF on the 7D good for surfing as normal AF points can often grab part of the wave etc that you dont want.
