    Recommendation for a binocular

    I'll second this advice and emphasize that once you find something you like, buy that exact unit, because unit-to-unit variation is a big issue w/cheap binoculars. If they won't sell you the demo unit, try the new one that they sell you to make sure that it is as good (or better) before you...

    ED50 fixed power eyepieces in the US?

    Could you explain in more detail what it is that you find unsatisfying? You mention the number of leg sections that need tightening, but the genius of the "ultra" series tripod design is that all tightening for each leg is done by twisting the foot at the end of the leg (i.e. a single adjustment...

    Why have helical focusers become popular?

    How about the B&L Discoverer scope w/helical focus, when did it come out? The 15-60x60 version was quite popular in the 1980s (and maybe didn't exist until that decade? Was there an earlier version with helical focus? The older balscopes and spacemasters had knob focus). --AP

    Fieldscopes

    The III is fully multicoated whereas the II is mostly multicoated. In practice, I don't see a difference. --AP

    how do you feel about the asymmetrical design of Pocket 8x25?

    I like the single hinge design well enough, but no more or less overall than a double hinge design with positive stops (e.g. Leica Ultravid). My only complaint about its execution on the Zeiss 8x25 Victory Pocket, is that the reach to the knob for the index finger of my right hand is actually a...

    Plastic lenses

    Plain glass wipes clean fairly easily, plastic does not, but if you buy plastic glasses, including sunglasses, that include hydro and oleophobic coatings, you will find them easy to wipe clean (though best practice is to use a bit of detergent and water). Lenses, whether glass or plastic, with...

    Eyeglasses - a few unqualified remarks

    For anyone reading this thread, my best advice is to use the posts here (and past threads devoted to eyeglasses in the BirdForum archive) as data or points to consider to accelerate your own thinking and exploration, but there is no substitute for finding what works best for you individually...

    Zeiss Dialyt Binoculars Rubber Casing Issue

    Use 3M VHB adhesive film (e.g. https://www.3m.com/3M/en_US/p/d/b40065871/ ) to attach it. Nothing better that I know of. Reversible if necessary, yet is super durable. --AP

    Dead forum

    I think the performance of this forum demonstrates that how you build it has a big influence on how many come. Unfortunately, the new build (i.e. the location of Watches in the Field) is inferior to the old. --AP

    Cornell Lab sub $600 8x42 review

    Indeed, so much so that I find polycarbonate unusable. Most of my glasses are glass, a few are CR-39, my progressives are Trivex. --AP

    Does the Manfrotto 501-PL plate fit a Gitzo G2380 fluid head?

    I haven't been on the forum for a while, so sorry for this late reply and maybe you've already got this sorted, but the answer is yes, those plates are the same overall standard. Also, Sirui makes some plates that fit, though they may not work exactly right with safety tabs/stops etc depending...

    Leica Pocket like all purpose bino?

    Could you please clarify which Zeiss Victory you don't like as well as the Curio? Presuming you are referring to one of the double-hinged models, is it the 8x20 Compact, 8x25 Pocket, 10x25 Compact, or 10x25 Pocket? If one of the Compact models, is it a dielectric coated unit or not? What leads...

    Jiggle, or 128rc issue

    Yes, I'm frustrated the same way. For Manfrotto, I've seen a fair bit of variation among individual units. I sent one back and it was replaced under warranty, the new unit having tighter tolerances. Glad your 3130 is better. If you find an easy way to disassemble and repack the other head, I'd...

    Swarobright Coating and P-coating

    Thanks all, for enjoying my post. I must say that I don't think I/we really nailed anything specific down here except that it doesn't seem like there was much concern for coordination between the various departments at Swarovski. The Swarovski advertising might seem surprisingly lackadaisical by...
