Canon is the preferred camera

Just a thought: The USM focusing motor whines at 30 kHz while Lions have an extraordinary ability to hear sounds that come from many different frequencies. They can detect frequencies that range from 55 Hz up to 79 kHz.. It might have been the ultrasound that attracted the lionesse's curiosity.

I've noticed some dogs get jumpy when I try to take their picture at a close range.
This in fact gave me the idea.
