Bryan has the chart for it. The 300mm F/4 with the 1.4x III is not as good. Since you have the 70-300mm L I don't think it would be a good option.

for 70-300mmL, you will lose AF at 300mm with the TC.Originally Posted by HDNitehawk
I was actually referring to the 300mm with the 1.4x III not being as good as the 400mm F/5.6. What I meant to say about the 70-300mm L is he has 300mm covered, in that regard the idea doesn't make sense as he is duplicating the reach he already has. I don't think the 70-300mm L with a 1.4x would be a good option.
oh, sorry Rick. BTW, i agree it's frustrating waiting for those new big lenes, how can u not say it's not a jock, it's more than one year, same thing as the 1D X,
Getting back to the original question, the only way that I have found to get high quality images in the 500 or 600 mm range that will allow major cropping without spending more than $10k on a lens that isn't even available to buy in a store yet is to use the latest generation of TCs with the EF 300 f2.8 II. With the 2x on it, the image quality is quite similar, once stopped down, to the original version of the EF 600. At wider apertures the 600 is better, but for the money it bloody well better be! At least when compared to the pricing of the hopefully coming soon 500 and 600 the 300 almost seems a bargain.
Canon really does not provide many options other than spending lots of money once you want to go beyond the 400 mm focal length.
The last I'd heard was when it was indefinitely delayed last fall. Just hoped that I'd missed some official announcement since with regards to it, as there were some prototypes made before the tsunami. Apparently that is not the case.
