NOTE:
the following makes no claim to be a scientifically reliable finding (I have been using my own eyes), nor is the result in any practical way relevant for birding or any other activity during which you engage a binocular.
Like many others, I have said before, and say it here again, that I find the SkyRover an optically exceptionally good binocular. It is so good that it has been compared to the best of the best, notably the NL Pure.
But I just had to know more precisely...
IS THE SRBC 8X42 AS SHARP AS THE NL PURE 8X42? OR EVEN SHARPER (it has been named "NL killer", after all)?
So ....
In normal use, out in the fields or woods and observing all sorts of object and surfaces, I could not detect any difference in sharpness between the two (and I would not expect to).
So as done before, I tried the two binos on the famous USAF 1951 with a few boosters (2.5x Kite Optics / 4x Zeiss / 6x Zeiss).
Are you still reading this? And you are even interested in the result?
Well .....
The NL "wins", and more clearly than I had expected. On the USAF 1951, at 10m distance
**, with good lighting, the NL goes deeper or further, as shown on the attached pic. While the SRBC lets me identify the pattern of the stepped assortment of spatial frequency specimens down to group C, element 5 (certain) / 6 (dubious), the NL clearly goes down to group D, element 1, so 1-2 elements deeper/further than the RSBC.

Happy, all the Swaro aficionados out there?
Caveat: the price of the RSBC is about 1/4 of the NL's, so the RSBC is not really "losing" here. For its price, it is a surprisingly good bino in my view (yes, I didn't mention quality control, I was just talking about the optics).
fwiw Canip
