About the optics of the Canon 10x30 IS: they're good. The 10x30's give me the most satisfying views I've ever experienced in any bin I've owned, including alpha's ( Zeiss 7x42 FL, Leica 10x32 BN, Swarovski 8x30 SLC ). That's what makes it hard to upgrade to the 10x42 L IS; considerably more weight, and quite expensive.
The big Zeiss ClassiC 8x56 shouldn't be on my list, for multiple reasons, price tag for instance. But I looked through them on the Dutch Bird festival ( never a moment interested in the complete FL line-up that Zeiss had ) and boy, did I fall in love again.
Anyway, today I was on my local patch, 10x30 IS's around my neck and 18x50 IS's mounted on my tripod, a clear sunny day and lots of birds. I couldn't help thinking: why on earth would I ever want new bins with these two doing so well?
It's the image stabilization that makes all the difference. The 18x50's were extremely sharp and bright, tripod mounted, no IS on. Much better for long distance viewing than any scope I've owned, that's for sure. Handheld with IS on, on occasion tracking birds flying high, it's even more amazing how functional these bins are.
The two bins have the same kind of image sweetness, and complement each other very well. Still, I wouldn't be surprised if I found myself in an optics shop to try out the 10x42 L IS one of these days. Maybe I should see a psychiatrist.
Best regards,

Glad your happy with your Canon's. For me I notice better contrast with the top alpha's. The Canon's are just dead in comparison. They are sharp but they just don't give me the feeling I have just moved closer to the bird. They are lacking something. Be happy that a $300.00 Canon keeps you satisfied and you don't have to spend the $2000.00 to get an alpha. Not all people discern the differences between low priced binoculars and the alphas and perhaps you are lucky you don't.
