Thanks Arash.

I surely agree with this:

99.99% of soft flight images are due to reasons other than MA.

Those reasons being operator error and camera body AF deficiencies … I test at about 23-24 times the focal length and find that with increased distances d-o-f covers and small changes in the AFA or FFT settings.

with love, artie

Superior AF for birds in flight. Both the current Nikon and Canon 600mm lenses are wonderfully sharp and well made. Yes, as discussed previously on the blog several times the big Canon lenses do much better with teleconverters in terms of AF performance where the difference is large and in sharpness and image quality where the differences are small at best …
