About the performance of the XF 10x42 has often been reported in detail which I fully associate myself. With binoculars you are probably reached the limit of what is possible for the abilities of the healthy eye. Therefore the XF10x42 is indeed comparable to many higher priced products. The package had everything as promised and the delivery was fast. I especially like the easy handling and operation of the glass. Note: Even though Vanguard is a US company, is the equipment made in China. Even though I knew that I was disappointed that. The workmanship is nevertheless very good.
