Summary: I currently have the Zeiss Victory RF 10x56 and the Swarovski EL 12x50 and I have to say it is very hard to pick the best. The Zeiss are a bit bulkier than the Swarovski but the optical quality is equal. The range finder in the Zeiss RF is unbelievably fast. I have Ranged out to 1500 yards and even at this distance the measurement is almost instant. Zeiss has developed an outstanding product and if these are within your budget you will NOT be disappointed.
