From Joan G.:
I've had the same pair of binoculars for many years and have been wanting to upgrade. I've tried out many brands over the years and could never seen any difference.
Last December on a cloudy day, I was testing several binoculars using an outside bird feeder as my target. I could see no difference in any of the brands until I picked up the Zeiss Victory SF 8x42 Binocular. The amount of light coming through and the clarity were so dramatic that I had no trouble deciding they were worth making the upgrade.
I took my new Victory SF to China on a birding trip and adapted to them very quickly. They are well-balanced and focus very quickly. The focus does stick occasionally so probably need to send them back for an adjustment, but haven't wanted to be without them.
Eagle Optics was very helpful and have been over the years we have dealt with them.
