new super telephoto lenses???

From the ISO 12233 charts, the 400 f2.8 with the 1.4 converter is nearly identical to the 500 f4 in IQ, both wide open. If I had the money to spend, I'd get the 400 f2.8 and 1.4 TC, this gives you the absolute best sports lens plus an outstanding wildlife lens with or without the TC.

I disagree. I think the 500 f/4 looks easily better than 400 x 1.4.


But heck, if that was true, what would be the point of the 500 f/4?
