Zeiss owns Schott Glass and that is where Zeiss gets it's lens blanks from. In fact almost any optics company that uses German made glass is using Schott glass. The tempered glass range on a lot of modern kitchen stoves is made by Schott as well. Leupold uses Japanese made lense blank and German made lense blanks, but all the grinding, polishing, finishing and coating is done by Leupold at it's Beaverton factory. I wouldn't doubt that Saworafski makes it's own glass lenses for their optics and for Kahles.
All I can say is that I've had the opportunity to shoot some rifles that were mounted with Simmons, Tasco, and lower end Bushnells. I will say that all of those scopes had horribe optics. I mean when looking through them I though the vision in my dominant eye had gone from 20/15 to 20/300. I could not clearly identify my target as a 10 ring if I hadn't already know it was a 10 ring. ,) One friend who fired one of my rifles said: the 7X power on his variable looked bigger than the 9X power on mine. To which I replied: yeah, but I can clearly identify the target through my scopes. THANK GOD FOR LEUPOLD.
Just because they are expensive does not necessarily mean they are the best pair for the job. Usually if you do some research you can find a decent cheap pair which does the same job as a thousand dollar one.
True on the last post. As for the money, Alpens seem to hold there own. They were the Winner of Great Buy Award in 2003, 2004, and 2005 as seen in Outdoor Life Magazine. It all depends on how much you want to spend as compared to what you need. You can take a peek here for stats and prices for comparison:
Every year many hunters and outdoorsman and women come out west from the midwest and east coast to hunt the prized mulies and elk. One topic that comes up often is altitude sickness. My advice for flatlanders is to get into the best possible shape. Start months before your hunt, usually really ramping up my cardio around March or April.
I run 5-10 miles 3 times a week, and also go for walks carrying my pack with about 50lbs to simulate what could be on my back. Another useful tip is to drink A...
