I did have a chance to compare my Razor HD to the S.2.
The build quality of the S.2 seems great and the fit and finish were flawless. I really like the form factor. Having something that fits easily into my pack makes me likelier to actually carry it.
I live up on a mountain and have a great view to the horizon 27mi away. There are a few horse farms, with black rail fences and the occasional whitetail deer located at roughly 1.5mi away. There are fields and wood lines with smaller objects that allow me to compare viewing in the bright light or in the shadows. All of this provides a great variety for comparing optics.
When viewing, the adjustable eyecup is excellent. It worked well with or without glasses and stayed in place when adjusted. Combined with the eye relief, viewing with the S.2 was very easy. I was always able to adjust it and see the entire FOV easily.
The focus wheel is not my favorite, but it works. It is fairly stiff to turn, so the scope was not steady when mounted on a tripod and making fine adjustments. I had to move it a little, then let go and look to see if it was focused. Then repeat this until I was happy. If it were a little easier to turn perhaps the spotter could remain steady while turning. Again, it works, but it’s not as easy as having a fine adjustment wheel like the Razor.
The glass. I have mixed thoughts here. If looking purely at resolution, such as an eye chart, it did quite well. I was able to see details such as a fly mask on a horse, or parts on a tractor rather well. The overall scene though had a white tinted almost milky look to it. Now, I am in VA and we do have humidity which certainly plays a part. Looking through other optics such as the Razor and some rifle scopes I saw a similar effect, but it was more pronounced with the S.2. It created a whitish ring near the outer edge of the FOV. There’s probably an optical term for that. It was less pronounced at lower zoom levels, but always more pronounced than other optics at a similar zoom. About 25min after sunset I saw a small light about 1.5mi away and was able to focus it to a very fine point light with the Razor. With the S.2 there was a small flare off the light I could not get rid of. I really wish I had another S.2 to compare to.
That’s some observations from last night and this morning.
