[QUOTE="CliveP, post: 3294630, member: 85835"] Whatever the magic part is my Viking Vistron 8x25 seems to have it. I first just noticed that I wasn't being bothered by any glare in strong low sun when I'm sure all my other bins would have had at least some kind and so I tried to angle the bin near to the sun at all angles and it still seemed to be immune. I will check again when I next have the chance but it really does seem to be the most immune of all my bins and I can't see anything special in anything about it by looking down the barrels or whatever and it isn't exactly a 7x42? I can see it's pretty well darkened and there is an abrupt step baffle (90deg) just before the prism and maybe the coatings aren't the latest as it's discontinued and perhaps a few years old stock but there is no CA either. It's not as good as the Bresser Everest 8x28 or Hawke Frontier 8x25 PC or any of my other bins for sharpness or distant resolution but it's passable. So some things traded off for others. Whatever it is, nice job, in fact the large view it gives is also pretty remarkable, just wish they had used something better to lubricate the focuser. It actually has a full size focus wheel (biggest I've ever seen on a compact) and I think you need it to turn the focus. No idea what's going on there. It's like they used really sticky treacle as you have no chance of acquiring a fast focus and almost have to wait until the gum or whatever settles down before it actually achieves a focus and it doesn't show any sign of ever loosening up unless I put it in the oven for a while or something. Absolutely brilliant little bin though just needs some dialectric and ED and an M7 focus and I'd spend £200 on one. [/QUOTE]
