You're discussing a lens without knowing its specifications?
Originally posted by MMVIII LamyTax, you are repeating this quite sour rant endlessly... I just looked it up, a Canon 600mm can't focus closer than 5.5m, a Nikon 5m, what do you want?
Is it brand loyality that makes you say that
600mm/5.5m or 600mm/5m is compareable to 560/5.6m?
It is not. It translates to higher magnification ratios with both the Nikon and the Canon. And every bit counts because then you don't have to crop (7000$ for a lens so you have to rely on cheap extension tubes and cropping? Awesome!).
Especially considering that for the Canon, you even have great working extension tubes available made by Canon.
Since the 560 is between 600 and 500, you might as well compare it to the 500/4, not much better. Matter of fact, it's not the longest lens but has the longest MFD.
The 560 isn't a birder's dream, or anyone who shoots smaller animals, for that matter.
I'm not sure what you guys are shooting, but you seldomly use such a long lens at long range anyway. IQ will suffer due to atmospheric disturbances. MFD, however, really matters.

Yes, yes, exactly. When you like the 560 that much, have you placed a preorder yet? I'm thrilled to find out how it will do on extension tubes. Or on 2x TC... oh, wait...
