About
Location: Hluhluwe/Imfolozi Game Reserve (the former Hluhluwe/Umfolozi Game Reserve), Kwazulu-Natal, South Africa Date: 12 Mar 2005 Capture: Canon EOS-1D Mk II, EF 500 f4L IS with EF 1.4x II, 1/350, f8, ISO 400 (The teleconverter was ?permanently attached? to the body to keep dust out when changing between the 120-300 and 500.)
Interesting question Pat. Never thought AF would get an animal's attention, but maybe they can hear the USM. But, I suspect the IS, and maybe scrunching the lens around on the beenbag, is louder.
