Image Stabilisation Modes

I have recently bought a second hand Canon 100-400 IS L zoom lens which I am extremely pleased with. However, there was no manual with the lens and I am cannot figure out through use, the difference between Mode 1 and Mode 2 in terms of the IS function. They both seem to do the same thing, but there must be a difference.

For the most part I am into airshows and motor racing, so the ability to pan both horizontally and sometimes vertically are the main requirements.

Can anyone help me out here

Thanks

Mode 2 is for horizontal panning; mode 1 is for shooting an erratically
moving or stationary object.

What he said but take the "erratically moving" part out.

Thanks for the quick replies. I guess it's mode 2 for me then.

Cheers

in mode 2 the element in the lens only moving on one axis (you have no stabilization vertically speaking). Used mostly on some kind of support.

Im sooo jealous!! Where did you find a used 100-400L lens? Do they have any more?

Took some finding - I've been looking around for about a year and the only ones to appear were the usual eBay imports from Hong Kong (which didn't appeal for some reason), or the occasional s/h lens in the US.

Being based in the UK it was not going to be 'easy' for both parties, I didn't necessarily know what I was getting, and the sellers tended to be reluctant to ship the goods out of the US. (especially to someone without a visible track record of purchasing through the bulletin boards)

At the end of the day however, I guess it's all about trust. A few emails back and forth tends to give a good idea of who your talking to.

I'm happy, got an immaculate and hardly ever used lens and it saved me a bundle over what I would have to have paid for a new one in the UK !!

Keep looking - it's worth it.
