我本来觉得和SW 8X30对比已经够夸张的了，但是在国外最著名的观鸟网站，竟然有人在它和莱卡、蔡斯进行对比，并选择全七观鸟！原文在2005年的一篇文章：

Hi:
My father has problem in one eye, and his vision is very bad with it eye. Consequently, he doesn´t like binoculars, he says that his vision with them is bad. What about monocular Zeiss? Are good for birding?
Regards
Hello Chabi,
The Zeiss 8x30 and 8x30B, manufactured by Zeiss Oberkochen (West Germany) in the fifties and sixties are superb binoculars, very sharp and bright and still capable of holding their own in todays high end competition. As Zeiss made a monocular version too, to be used as a lens for their Contaflex camera, I can imagine you are considering these. They are offered on eBay quite regularly in excellent condition, and quite cheap too.
BUT! A monocular, even the optically best, has one big disadvantage: you never can hold it as steady as a binocular. If I lost sight in one eye myself I'm sure I would never use one. Instead I would block one barrel (no light there) and use only one half of the binocular.
I think you could turn the disadvantage of the lost eyesight in one eye into an advantage here by using a binocular with individual focussing (see the others post too). Those military spec binoculars are usually very, very sharp, right to the very edges, and they are often optically corrected for a superb flat field. The Fujinons are good suggestions but if you want a cheaper solution I would suggest the Russian BPO 7x30. I use one of these myself quite often, in fact it's one of my favorites (among Leica Ultravid, Zeiss 7x42 B/GAT*P* to choose from). These BPO's are infamous for their yellow colour cast but if you can live with that (I certainly can, even more so, I even like it, as I feel it's often more natural than the exaggerated brightness in much of the optics of today!) you might present yourself with a birding binocular with very special qualities: unsurpassed edge to edge sharpness, unusual large field of view (150/1000 m), superb contrast and resolution.
After I gold hold of one of these instruments a year ago, and learned I loved the view so much, I've made a few modifications. In fact I custom-made one out of two! Now it fits my face and eyes to perfection, with the accommodation to eye relief exactly right (just try to find these qualities in a ready-made binocular, it might take you years, you might never even find the right one!).
The bottom line here is that, if you are interested, I could supply you with a few hints and tips with respect to the BPO 7x30. I could also supply you with the 'ripped off' BPO that I have here - it's still usable, certainly for one-eyed viewing. You simply could try it out, form your opinion, keep it or return it to me, whatever. Just mail me.
cheers,
Renze de Vries
最精彩的一段是：这个镜子因为偏黄而臭名昭著，但如果你能接受这一点（我本人当然可以，而且我甚至喜欢这一点，因为我觉得这比当今那些过分夸大亮度的镜子更真实！ ），你会得到一些非常特殊的品质：无与伦比的边缘到边缘锋利，不寻常的大视场（ 1000分之150米） ，超高的对比度和分辨率。

这都无妨，我的第一印象是可以长时间看而不累，画面平直细腻，耐看。
