[QUOTE="Steve C, post: 1275154, member: 56622"] A few days back, there was some discussion of a new make and model of binocular that Cameraland NY is actively considering selling. The discussions developed at the 24 Hour Campfire and eventually migrated here. I have had a test sample from the dealer in hand for a couple of days. So here is a post of my impressions. First the specifications; Power: 8X or 10x • Objective Lens Diameter: 42mm • Type of Prism: BAK4 • Roof Prism Coating: Silver and phase coated • Number of Lens: 8 elements in 6 groups • Body Construction: Magnesium Alloy • Objective Glass: Extra Low Dispersion (ED) • Lens Coating: full broadband multicoatings • Water, dust, and oil repellent coatings • Focus System: Internal center focusing • Exit Pupil Diameter: 5.2mm/4.2mm • Eye Relief: 17.2mm • Field of View: 8x=7.5° - 393 ft. @ 1000 yds. • 10x=6.3 – 330 ft. @ 1000 yds • Minimum Focusing Distance: 5’/1.5M • Diopter System: Right eyepiece - ±3 • Waterproof and Weatherproof: Nitrogen filled fog proof • Weight: 27.48 oz. w/o strap or lens covers. For the record I do not know where this binocular is made or just who makes it. This is the only binocular I have seen in quite some time that comes in a leather-looking velvet lined-looking hard case. The case is bigger than needed by a tad, so the binocular is quite easy to get into and out of the case. The eyecups do need to be all the way down for the case to close. The eyecups have two stops, at halfway out and fully out. There is a reasonable firm detent at each stop and side play in the eyepiece at each stop is minimal. The Diopter is a standard right eye, non-locking ring style. The movement is stiff without being difficult and will likely show little tendency to wander out of adjustment. Minimum IPD seems to be 56mm. The focus knob is large and well placed above the upper bridge. This glass seems to have less space between the hinges than I seem to recall in either a Swarovski EL or Vortex Viper. I remember those as being three finger openings, this one has a two finger space. It looks quite a lot like the Bushnell Infinity and I would not be surprised that they share the same housing. The optics, however, are quite different. There are two aspects of this glass I do not like. First the focus wheel operates through a frustrating 2 ½ turns. I am not sure if this is intended to be a dual system focus that is supposed to operate differently at near or far distance. What it is, is too slow. It turns smoothly with the just the right amount of effort. It just turns too slow. I suspect a fix is in order here if this is to become popular.
