I have had the Zeiss SFL 8x40 for a few months now, and I have used it extensively birding in bright daylight and in the evening at dusk, and I just can't find anything really wrong with it. It is kind of like a Triathlete. It is not the best at everything, but it seems to do everything a birder needs pretty well. It is more compact and lighter than an NL 8x42 or Zeiss SF 8x42, and it doesn't have the glare issues that the NL 8x32 and SF 8x32 do.
In fact, it controls glare better than most binoculars I have used, and if you go down the list it is pretty good at everything. It has very sharp edges, very little CA., the color purity is the best I have seen in a binocular, it is very sharp on-axis, very bright with almost 92% transmission, and it has no RB to speak of. The ergonomics are excellent and that is what set's it apart from binoculars like the HG 8x42. The Zeiss focuser is in a better position, and it is much smoother than the HG.
The optics in the Zeiss are a notch above the HG also with much better contrast and color purity. The whites are whiter and the blacks are blacker. The NL 8x32 and SF 8x32 have larger FOV's but after trying them both I realize they both have glare issues and the NL requires overly sensitive eye cup adjustments probably because of the wide FOV. The Zeiss SFL 8x40 to me is a smaller version of the SF 8x42 or SF light. I nominate it for nest new birding binocular of the year.
