I purchased these binoculars after conducting much research on binoculars. I have looked through some others of the same magnification and supposed better quality - for the money and with the IS these bins outperformed any other hand held.

Reliable; Durable; Superior build quality; Easy to use

After reading countless reviews it came down to these or the Swarvorski 10 x 42 I had the opportunity to look through the Swarvoski's and they were absolutely stunning the only problem being the lack of image stabilising. i had no opportunity to try the Canon's, no one seemed to stock them locally.

Yes these are larger, bulkier and heavier than a conventional binocular but no other binocular type gives you the ability to see incredible detail by eliminating shake. I have a couple dozen binoculars from cheap to Leica and these totally obsolete them all.

Do you really need this costly binoculars? For something around two hundred, you can get high quality binoculars with IS (Image Stabilizer)

Yes, top quality; Very very clear, Image Stabilizer quite helpful when your hands are shakey; L series from Canon are always top quality, providing you with images practically as sharp as your own eyes..; but cons..

Cost.; About one grand is a lot for binoculars; Unless you really need this kind of clarity, stick with something around two hundred dollars

Gives an awesome magnification it's worth spending money on

Had mine a year now. Amazing performance, from the near perfect optics, close short focus to decent true field of view. The stabilisation is a total game changer, the extra detail you see when your instrument is stable is a true eye opener. You see the world in a new light!
