Next step up over SIII 10-50

That's interesting. When I was shooting with the Weaver T-36, adjusting the AO (Adjustable Objective), was not too much of an issue. It was easy to adjust and you could go directly from one yard line to the other with no problem. Once it was set for that yard line, I did not have to fiddle with it again. The AO is actually better in many ways to a Side Focus. And it is one less lens in the scope. On the other hand, I can see where a side focus is better if you're changing distances and have to adjust from position. And if you're an old fart like me.

I am.

Matt, I assume you meant fluorite lenses. Fluorite glass is not found on riflescopes because it is rather fragile compared to non-fluorite glass. Fluorite glass has the inherent quality of eliminating chromatic aberration and it is also quite a bit lighter than non-fluorite glass. It's also a b*tch to work with ($$$) fashioning bigger lenses.

I was not familiar with the Kowa Highlanders so I went to their website and discovered the Kowa High Lander, big ash binoculars, available with fluorite crystal glass lenses ($5,500) or Normal lenses ($4,000). These optics are much simpler than riflescopes or camera lenses and the fluorite lens will have to be the objective lens since the eyepieces are removable, and sure enough that's what it says at the site: "fluorite crystal objective lenses" 82mm of fluorite crystal goodness. And cost ($$$). Times 2. That's $750 per lens, right there.

Your observations totally reinforce my earlier diatribe that it's extremely difficult for someone (anyone) to detect a difference in high end glass. You have to know what to look for. Your observation about the blood trail is what I was explaining about chromatic aberration, or color fringing. When CA is not corrected the contrast between colors is not as crisp. A red blood trail on snow will be very thin but the CA correction of the fluorite lens (think super-ED glass here,) made the red of the thin trail of blood pop out. Mission accomplished and it only cost $1500.

So for F-Class weenies, think about those tan circles on the aiming black. With my March-X ED glass, those lines are crisp.

And read what I said earlier about mirage.

You can buy the regular ones for 2800 and the others are 5500. Roughly 3 grand more.
If you ever get a chance to look through a pair, do it. I believe Erik Stecker has a pair for his spotter. I believe I saw a pic of him using them. It is the ultimate long range hunting glass. Very bright, crystal clear and more detail, with great depth. I have looked through many astronomy and birdwatching binoculars. Have found none that compare.

I don't worry about seeing the circles. I just put the crosshair on the 4 inch white patch and center. But BR is a different game. In our game group takes precedence and it doesn't matter where it's at. Matt

Pretty easy one, just read the first page of the 2017 catalog

Ray

Thanks!!

I was basing my prices on what I found at Euro Optics. They have the regular lens at $3,575 and the fluorite lens at $5,000 even. Ready to ship. B&H Photo has the fluorite model at $4,799, with free shipping.

But yeah, if you were more concerned with the rings, you might be more interested in ED glass, but since you're only concerned about missing the target in a small group, why worry about chromatic aberration?

Ok. Nikon site says 1971, but I'm sure they were thinking about before. Nikon and Canon have always played off each other and I think that's helped both, and the consumer.


This year is the 100 anniversary of Nikon so they have lots of historical information and their website.

I like Nikon cameras and have had them for decades. There's even a song about that. Simon and Garfunkel some time in the 1970s. I shot a lot of Kodachrome and Panatomic-F. Now it's all digital.

Actually it was a Paul Simon song, "Kodachrome" LOL.

I had a Nikon F back in the day, but it wasn't legal for F-class,

I still have a couple,lol
