I got a deal on the Canon. Not near the moola of the SV 10x50 and it is fun to mess around with. Even though I can hold the SV 10x50 steadier than any 10x50 I have tried the Canon is rock solid with the IS engaged and it has pretty good optics. It gives me a 10x among all my 8x32's(SV 8x32, Nikon 8x30 EII, Leica Trinovid 8x32 BA) to use when I want something for long distance higher power viewing. I have never used a 10x that much but I am beginning to appreciate their reach for hawks and eagles and distant wildlife viewing. You do get a little more detail which is nice. Kimmo has shown in his testing of the Canon 10x42 IS that a 10x binocular loses about 30-40 % resolution versus tripod mounted and the Canon 10x42 only lost 8% resolution versus a tripod with the IS engaged. So that's a 30% resolution advantage over a hand held binocular even without the optics coming into play. Also, Kimmo showed that the Canon 10x42 IS even out resolved the Nikon 10x42 SE WITHOUT the IS activated so it has pretty good optics even without the IS being used.<a href="http://www.birdforum.net/showthread.php?t=297776" target="_blank">http://www.birdforum.net/showthread.php?t=297776</a></blockquote>
