Optically not as good as my non stabilised Leica's but I guess the money is in the stabiliser tech rather than the optics despite the "L" designation. The cheap and nasty lens covers don't fit properly, keep falling off, are of poor quality and unworthy of an item with this price tag.

Stabilisers Work Well

Bulky; Caps Are Cheap Rubbish; Heavy; Not Worth The Money

I returned my pair. I expect much better. As hard as I tired, I could not get the focus perfect. Another review said the same thing. Also, to much focus float when image stabalization is activated. The image stabilization does work.

Gives an awesome magnification it's worth spending money on

The 10x42 IS binoculars are very nice and provide a sharp image which is perfect for bird watching and other uses. They are a bit on the heavy side but are still better for overall use than the comparable 12x36 IS binoculars that these are replacing.

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!

It is easy to get spoiled with image stabilization for binoculars. I chose the 10x42 L over the 15 or 18x50's because I wanted the largest aperture/power that I could still hand-hold if the batteries died.
