My response to OP is this: I have the NL Pure 8x42 and the Nikon Premier, (I think that is the name), 8x32. I like both a lot. The Swaro is superior and I am very glad I own them. The Nikons are great binos though. They are like old friends. I use them in certain situations because I am not yet relaxed about banging a pair of $3K binos about on a rough canoe trip. Still, when I returned home off a canoe trip last week I was reminded just how good the Swaros are. I just need to ding up the Swaros a bit. I am sure they are every bit as rugged as the Nikons. Once I relax a bit with the Swaros, the Nikons might start collecting dust.
Long story but I had a small incident with the Nikons on the trip. They ended up landing in the sand. They were completely covered in sand . Ugh. But, I rinsed them off in the lake and then after they dried I went over them thoroughly with a soft brush. Every nook and cranny. Then a lens cloth. They ended up perfect. No sign of any damage whatsoever. No scratches in the glass or the body armour. The Focus knob is smooth and consistent - like the day I bought them. The eye cups are perfect too. Great binos.
