Kowa 664 vs Kowa 82SV

If size/weight were of no concern, which is preferable for hunting?

Hi

You'll do fine with either one. Really a personal preference. Me, I'd opt for the 664 for the smaller size and less weight and also better contrast and image quality. Smaller scope size also allows you to use a lighter and therefore cheaper tripod. The 664 would be the all around more user friendly package. The 820 will have a slight edge on image brightness if you will be doing a lot of scanning in low light, though. That could be a factor, depending on when you are using the scope.

Thanks for your valued input. I was leaning towards the 664. Off topic, I'm interested in the Leupold Kenai scope as they call it "HD" but I can't find in the specs where they (Leupold) come out and say the glass is in fact ED,HD,APO or whatever the term would be. The price looks good and I'd like to know how it performs. Of course the Kowa is well known and is a safe investment. Just curious.

Hi Gary

I haven't had a chance to test that Leupold, so I'm flying a bit blind, here.

The problem with these special glass designations is that they aren't actually derived from a specific lens formula, so one manufacturer's HD can be quite different than another manufacturer's HD or, for that matter ED and so on. These labels are as much marketing as anything specific, in other words. Moreover, the labels, in and of themselves, guarantee nothing as to performance. How the lens is figured, as always, is the real limiting factor. Given a choice, I'll take a well made lens of standard formulation than a lesser lens with fancy glass. One of the best 60mm scopes I ever tested, for instance, was a Kowa 601 - a non-ED scope. I also tested a Swarovski ATS65, once, that was virtually indistinguishable in performance from a Swarovski ATS 65 with HD. What I am trying to say in my long-winded way, is not to take these special glass labels too literally. A scope does not have to have HD or ED to be an excellent scope.

There is also the matter of eyepieces. While I've heard the Kenai zoom is adequate, I can't imagine that it would keep up with the 20-60x series 600 zoom on the Kowa - I own a Kowa 663 and will vouch for the zoom on the Kowa (not to mention the scope). Still, until I test a Kenai, I'm speculating as to its performance. Hopefully, someone who owns a Kenai will post for us.
