Well, full disclosure… I’m a Leica guy. In 1983, my Dad bought a 1957 "Double Stroke" Leica M3 rangefinder and I was hooked. The quality of that camera blew me away. Four years later, when I was in college studying photography, the class had access to Leica lenses, but no cameras. That glass became mine for the length of the course! Over the years I've used a lot of camera gear. From Leica M to Leica R, Canon (20 years), Nikon (10 years), Mamiya, Hasselblad/Zeiss, Contax/Zeiss, Sinar/Schneider, etc.,etc.,etc.. Consequently, I like glass from camera manufactures.
I also own a few rifles scopes. Two of my scopes come from Nikon and one from Leica. The only gun optic I have that isn't from a camera company is a Meopta MeoSight III, 1x red dot. Interestingly, the scope I think I'm most impressed by is the nikon M-223 1.5-6x24 Illuminated BDC 600. The scope that has my heart, is the Leica ER 3.5-14x42.
So... I'm biased, I admit it.
Just to recap, while the BN has been in my possession, I have simultaneously had the luxury of using several high end binos. My fabulous friend (who is the industrial sales manager at the largest camera chain in western Canada) loaned me a Swarovski 8.5x42 SV, a Swaro 10x30 CL Companion and a Leica Sliverline 10x42. To my eyes the CLs (I looked two different pairs) have faired the least well against the Leica BN. They had slightly less visible chromatic aberration, but were no better anywhere else. In fact, when it came to flare and brightness, I scored the older Leica BN ahead. The SV and Silverline bins are better in every way, except for size and weight. I can buy the SVs for $2700.00 CDN, the Silverlines for $1350.00 CDN and the BNs for $900.00. I was expecting, maybe even hoping, that you guys would shoot down the BNs and admonish me for even entertaining the idea of buying a 10 year old binocular! Much to my surprise, the majority of you have been supportive of the BN purchase, and I can't dismiss that. To my discerning, well tuned eyes, the Silverline bins are probably worth the $450.00 premium, but I don't want silver tubes.
The Swaro SV are the best... period. Are they $1800.00 better? Not to my eyes.
I'm going with the BNs!
Now... In about a month or so, the Nikon rep will be letting me sample versions of Nikon’s HG 8x42 and HG 8x32. I can't wait!
