I was in Ankeny today, so I stopped at Sportsmans whse, as I have been wanting to compare my 8X43 ED2's against the Swaros. They had a $2000 pair of 8 powers in stock, so the sales rep and I went outside to compare them. We focused on some grain elevators approx a mile away ,NE of the store, directly over Menards roof. I honestly challenge anyone to tell the difference in optic quality, and further more, in toughness, construction wise. The entire staff in optics were amazed at the crispness and clarity of my binos. One sales rep wore glasses, and he thought the swaros had a little better eye relief for him. Mine cost $400 new, and have a lifetime, transferrable warranty. I am not afraid of spending $ on the best equipment, and to me, I did, as there is no way, a $1600 difference in the pair. Like Vchris said, euro glass prices are going to have to drop dramatically, once the word gets out on the Zen Rays.
