Quote let me know what you think. you guys are great help, this is a much more relaxed area than the rest are.

 

I think the folks here just enjoy being able to help others out.

 

I would stand by the original suggestions considering your situation.

I cannot help you with those. I never owned a pair of them.

SWFA has them under Leupold Yosemites. In essence, everything but the Golden Ring bins are Green Ring binoculars.

The 8x30s aren't listed yet.

The Leupold Mesa 8x42 is slightly more expensive and would offer better low light performance as Frank already suggested.

The Mesa series offers aspheric lenses which supposedly achieves a higher contrast and optimizes focusing along the perimeter of the field of view.

I think you would be surprised by the image quality of this little gem. I used the 6x30 Yosemite during archery season and must say that I did not mind the 6x magnification one bit. They provide a bright image with excellent depth of field and a relatively wide sweet spot without distortion.

so maybe the 42 mm would better serve me for early morning late afternoon light levels

My closing thoughts are this: now that you have a good idea where to begin, you need to go to a sporting goods store in your area and start handling and looking thru binocurs, in the range we discussed.

A good time to go would be around sunset, so that you could compare binoculars, outdoors, in a low light setting.

Do porro prisms offer more or less fog resistance than a gas purged roof prism? That is important to me. With the binoculars I have tested in the field, they still fog a bit (especially when my eyes water as they did on one particular hunt).

Fogproofing with different gases is an "internal" benefit of porro prism and roof prism binoculars.

Some companies like Bushnell and Pentax, for example, do advertise "exterior" optical coatings that supposedly minimize exterior fogging and supposedly shed water better.

I believe that you can buy exterior fogproof lens cloths, and even liquid, which can be applied to the exterior of your lenses, to help with your problem.

I think the internal gases help some with exterior fogging. In my experience, the fog seems to subside in relative short order, as compared to some of the older and cheaper binoculars I have used where I basically have to wipe them clean or it would take an hour (unfounded personal estimate) to clear up.

I believe you are talking about two different things here -- internal fogging isn't the same thing as condensation on the exterior of the ocular and objective lenses.  The former is moisture trapped inside the bino due to not being completely sealed; the latter is caused by nothing more than a rapid change in temperature or atmospheric moisture getting on the lens surface.  A couple of manufacturers are now offering hydrophobic coatings to help combat the exterior condensation, but gas purging on the interior has no effect on the exterior lens surfaces.

 

In general, porro prism binos are usually less fog resistant due to the exterior focusing mechanism vs. the roof prism's interior mechanics.  It's just easier to seal and gas purge a roof prism due to its design differences.

Well true...but both are condensed water vapor with temperature playing a role in their occurance. At any rate, I was speaking of external condensation/fogging and all I was trying to note was that purging seems to regulate or resist against external fogging to some degree.

I don't see how it's possible that internal gas purging would have any effect whatsoever on external fogging.  Almost all riflescopes are nitrogen or argon purged and yet if you breathe on the outside lens surfaces in cold weather, they immediately fog up.  What I meant was with an unsealed, non-waterproof optic, there's a pathway for moisture to enter and fog the inside, yet it takes longer for that moisture to escape the interior than condensation on an exterior lens surface, which may be why you're noticing the purged, waterproof bino lenses clear up more rapidly.  Since the inside of a purged, sealed bino should have no pathway for air to pass from outside to inside, it has no effect on exterior condensation.

Well speaking as a layman on the subject, it would seem logical to me that because the temperature change of glass plays a role in the condensation of water vapor on the glass, the molecular makeup of the air surrounding the glass would make a difference. The gas (nitrogen or argon) changes temperature at different rates than the outside air. That being the case, the inside gas is more resistant to a change in temperature which is in direct contact with the glass and so effecting the glass temp. I could be way off...but it sounds good to me . Regardless, the bottom line is that yes external fogging still occurs, but at least in my limited experience with purged optics, they seem to clear on their own more quickly than non-purged binoculars.

Plus, there's no problem if you accidently drop 'em in a creek... unlike my wife's digital camera, as I painfully discovered on a recent elk hunt...

Zip-Loc freezer duty sandwich bags solve that one RD. I use em all the time now when I stream fish. Of course I drowned two cam's before that discovery.
