On my recent trip to the KNP I've noticed once again that animals tend to react to the noise that Image Stabilisation motors of Canon IS lenses make. On various occasions animals look up at me as soon as I focus (that's when IS kicks in). Although it's a good for photography when subjects look at you it's a shame that that this IS noise seems to alert the animal. Has anybody else noticed this?

Some animals can even show their annoyance. Last week I was taking close-up pictures of an elephant in Sabi Sand. As soon as the IS kicked in he looked at me and shook it's head. I continued to take pictures untill the elephant decided that he'd had enough of it. He reached down and with his trunk he picked up some mud which he flung it at me. Fortunately the mud didn't hit me; it hit my wife who was sitting behind me :lol: :lol: :lol: :lol:

:lol: :lol: Madach.

@DuQues: most animals have much better hearing of course. Perhaps there's an irritating sound that we can't hear at all.

Animals don't seem to have any problems picking up the noise, I guess their hearing is better than ours. The animals that reacted to IS noise the most were Kudu, Nyala and Elephant.

Thanx DuQues, that tells me enough! :lol:

It might be a sound with a fairly high-frequency, I wonder?

Similar to non-AF-S/USM lenses, sometimes the focussing noise can irritate animals. Not as much as celphones ringing though... :x

I know that when u go hiking or walking in the Park that motorised cams aren't recommended.

Animals react to it in a very wary way. They either like the elephant Madach spoke about become aggresive or they flee.
It is diffcult enough to get close to animals whilst on foot and those cameras just make it more difficult.

there was this story I read where an animal attacked when it heard the noise of a cam. The trails ranger had to react quickly. I'll try and find the story and post it here.

We had an a rhino charge our vehicle after he heard the camera focussing. He appeared really angry and we had to do some major reversing to get out of his way. After that my brother was instructed not to use that camera when we were near dangerous animals. It took hours for our nerves to settle. :shock:

Not unbelievable when you consider they all have large ears. Still I am surprised that the stabiliser should be worry them :? What about your cars engine before you turn it off, or the movement within the car?

I've also found that animals too want no part of Steve Hoffmeyer
:P
