Yes; they are all excellent, I've also tried all four, and briefly compared the NL 12x and the SF 10x side by side in the field; and the 10/12x NL and the 8/10x NV side by side in shops/outside.I am in the hunt for the best. Buy once, cry once bino purchase. I have narrowed the search field down to Leica Noctivid 10x42, Swarovski NL Pure 10x42 or 12x42, or the Zeiss Victory SF 10x42.
Anyone else been down this path? Surely I'm not the only one. Thoughts?
My preference for what its worth: NL then NV then SF.
The NL shaped design does seem easier to hold for me than the traditional. The wider FOV is always good. And I'd simply say get the highest magnification you can hold steady enough (and carry in your terrain).
I also found I could put both Leica and Zeiss up to my eyes and they work. The Swaro I had to spend a short time getting the oculars adjusted just right, then they work.
No regrets spending on the 12x42NL which I use consistently for birding.
The NL armour surface scuffs though I guess underneath it is essentially as robust as the others. And the objective/ocular covers were very tight, but are fine once carefully trimmed. My two nitpicks on the NL.
