Message: <blockquote data-quote="mfunnell" data-source="post: 3334234" data-attributes="member: 134332">Correct.  Vortex isn't making such claims for this line of bins, which are towards the lower end of their range.  (BTW, as far as I'm aware "ED" at least means something in terms of glass type, but "HD" seems a pure marketing term.  If I'm wrong about that, could someone please educate me?)I think that depends on which format you're talking about.  Examples: the 8x42 format has eye relief of 18mm in both the old and new; the 8x28 goes from 19mm to 18mm while the 8x32 was 12mm in the old model and offers 15.6mm in the new.  So I don't think there's any sort of general trend there in the new models.If you just look at the specs, these seems a bit of a mixed bag; with some numbers improved and some moving the other way.  But some things aren't captured in the usual published specs - we've no way of knowing what changes to optical design, coatings etc. will do to the view without looking through them and/or measuring things such as transmission, CA, distortion etc.  I'd hope they are improvements on previous designs but it's hard to be sure of even that, given the interactions between the brands specifying the binoculars (or just selecting from option lists) and those actually manufacturing the bins.  (That's something I'll confess I know all too little about.)The two formats I'm interested in are the 8x28 and the 8x32.  I'm interested in the 1st because I have the old model (two of 'em, in fact) and find it a pleasing and useful compact bin, so I'll be interested to see how the new one compares.  I'm interested in the 2nd because it looks good on paper and perhaps would even be useful to me (I never really considered the old model as it's 12mm eye relief wouldn't work for me; 15.6mm probably would).   ...Mike</blockquote>
