what have you tried cleaning it with? moist towel? alcohol rub? I had a similar thing on the grippy textured rubber of my 5D Mark II and I'm trying to remember what I did to get it out, I think I used lens cleaning solution

Shoot with left eye . . . literally.
Used to drive my grandfather crazy that I'd pull up a .22 and rock my head across it to aim (right-handed).
Do the same with the camera now that I think about it.
As for 2-eyes vs 1-eye, only shoot with the right one open if I'm trying to track something.
I also hope Canon wouldn't put IS in a 17-40 lens just to boost the price. For a lens whose primary use is on a tripod, that would be silly
I am worried about the Hybrid IS since someone in this post said that, because of it, his/her photos were soft (and sharp when tuned off). Though, it was only 1 comment going that route.
Nah, that's either a broken lens or people simply don't realize that IS doesn't stop the world around them and the effect diminishes to nearly zero when going near 1:1 mag. And with very fast shutter speeds you should turn IS off because the lens shutter speed is faster than the IS sampling rate resulting in a bit of blur.
The advantage of the hybrid is over other IS systems is that esp. with a 7d/5d3-type af system the lens speeds up the sample rate, so tiny adjustments are adjusted plus it also compensates for forward/back movement next to panning. It's a theoretical advantage esp. when shooting med distance handheld macros, but I wouldn't make a lens choice Canon/Sigma depend on the hybrid is - the downside is that it's noisier and might be more prone to failure since it's more complicated.
And I was wondering what the other lens they were announcing would be. I knew the 18-35 was being redone, but the 800 was a surprise.Seems like that price point for that lens drives the nail in the coffin of any "update the 17-40" efforts. The going rate of an entry wide-zoom seems to be $750-$850, and I doubt they go cheaper.
