Its negative impact can be lessened (and
sometimes removed) at diffraction-inducing apertures, at which point
you're fighting other sharpness loss than the lens system anyway

thank you czeano for pointing that out, never think about that before.

and the 2X extenders reduce AF Drive Speed by 75%

thanks Rich for the information. 75% sounds really bad, but Canon claims that the performance of the TC III in real world won't be that bad if using with their version II lenses and 1D or 1Ds body, so we will see soon.

I think Canon is not being very clear on this. It seems their saying, that AF Tracking and AF Precision will be better with the New Super-Telephoto Lenses and New Version III Extenders, therefore AF Performance will be better, however it still sounds like the AF Drive Speed will be just as slow as it was before with the Version II Extenders. It sounds like the increased performance, is accomplished at the expense of speed. But, maybe your interpretation is better. Anyone else have a different interpretation?

Nate,


Nice shot of the Tern & chick,


the only thing I see is perhaps a loss of detail in the blacks (hard to expose for blacks and whites at the same time though!)


Also I would evict the stone in the left lower corner
