After nearly three weeks of constant birding with the Noctivid 8x42s I can give a few considered impressions. As an overall comment I'd say they deliver a truly beautiful image - wonderful brightness, contrast and sharpness, nice wide field of view (though not the widest available), huge depth of field and simply gorgeous colour rendition. Handling is fine for me, though it took a couple of days in the field to feel as comfortable with them as I did with my UV HD +. This is because they need to be held differently. With the HD + my hands were almost fully over-lapped. With the NVs I have my left hand further down the left-hand barrel and my right hand immediately below the the strap lugs. My hands are on the small side but with my right-hand fingers spread the focus wheel is perfectly placed. This gives a lovely, steady, balanced feel. In reality, after a couple of days it was instinctive and I don't even think about it. The slight weight increase isn't noticeable in the hand, due to the excellent balance. Around the neck they feel slightly heavier than their competitors but it feels marginal. I've been birding with users of HD+, SVs and SFs but not HTs. All have wanted to try the NVs and all have remarked on the exceptional image quality of the NVs. They are slightly brighter and more contrasty than the the SFs and noticeably more so than the SVs. They have a huge sweet spot, though aren't as flat and corrected in the outer 10% of the field as the SVs and SFs, which I like, as panning (which I do a lot of when doing migration counts) is without rolling globe. Comments by owners of HD+, SVs and SFs have usually started with something like "Wow. These are extremely bright and sharp". One SV owner said "If I'd tried these I'd never have bought the SVs". Another birder whose binos aren't any of the above but who tried them all said " Well if I ever win the lottery, its NVs for me". Another interesting comment was "Are you sure these are 8s - the birds just look bigger in the NVs". You can see this particularly if you move back and forth between SFs and NVs - sometimes small birds which seem a bit "lost" in the ultra-wide SF field of view just "pop out" with the NVs. All who tried them commented on the depth of field and the lack of need to be re-focussing as birds moved. Whereas it does take slightly longer to move from 6 feet to infinity compared to the other premium bins ( I reckon we're only talking a couple of tenths of a second longer) the NVs will, amazingly, focus from 10 yards to infinity with just one quarter of a turn of the focus wheel. So, to summarise,if you want the widest field of view, with a lovely easy view and weight is an issue, I reckon it's the SFs. If a sharp, absolutely flat field floats your boat, then it's the SVs. But, if you want simply the most beautiful image yet delivered by a binocular, then I reckon its got to be the NVs.
