400 f/2.8 IS MkI + 2xTC MkIII


Thank you Ian, Matt and John for your feeback.

I think the combo is certainly a way for someone to get a fairly decent 800mm f/5.6.
The resolving power is not on the 800L level, but neither is the combo price.
Stopping the lens down improves the combo's sharpness a bit.

Here's another shot from the same series, just about 50-60% cropped.
