I performed a star test with the 8x42 NL as well as with the SF 8x32. Both show at the very edge of the FOV a small deformation of the star, the SF a little stronger than the NL.
With regard to comments on the body armor of the Swarovskis: I have used Swarovski, Leitz-Leica and Zeiss binoculars now for many years and none of them ever had any problem with the body armor despite very harsh conditions in all kinds over atmospheric circumstances. Deet, however, destroys body armor quickly as I have seen from different users, but I have always avoided DEET.
The focussing wheeel of the NL 8x42 I now have operates very smooth, no problem whatsover. The diopter ring is very tight and does not move unwanted in my hands and it is easy accessible with the binocular in use.
There is a distinct but small difference in overall color balance: the NL makes whites perfectly white, the SF makes it a little more brown red, nothing to stay awake from, but it is there. I am waiting for access to the laboratory to find out how the transmision spectra will look like.
Although I am not a fan of objective covers, I can live with the NL ones, moreover they can easily be removed.
Close focus and FOV are almost identical for the 8x32 SF and the 8x42 NL.
Focussing of the NL is a tiny bit more smooth than that of the SF.
With regard to handing comfort is the 8x42 NL a clear winner over the 8x32 SF as far as I am concerned. Both are excellent binoculars.
