Excellent birding bins. They accept a little more light than the Nikon Monarch 7 bins I have been using. Ergonomics and general feel are good and focus span is quick enough. I am an eyeglass we're so the eye cups are always full down position but they don't lock in solidly. That is my only negative.

Great in low light

Outstanding optical performance and design. 10X magnification with depth and width of field comparable to Good 8X binoculars. Very fast focusing. This allows for very intuitive "Point & Shoot" characteristics (like 8X glasses) but with 10X detail.

Now I can see the birds!! I had been researching, trying to decide what brand of binoculars I was going to get to supplement my 12x50 set.

I own a pair of Nikon Monarch 10x42 binocs and they are pretty decent. I was going to get a pair of Monarch 7 in an 8x42. When I saw the deal on the Zeiss, I bought them instead. These binoculars are definitely better quality!
