NIKON好一点点,但个头大些重些,配件差很多.也便宜一点.

有钱还是买徕卡：）

NIKON的性能好些,毕竟是晚了好几年的技术.

hengheng · 发表于 2002-12-11 23:44

请具体分析一下好吗，麻烦您了：）

NIKON的视场大些(7.8对7.7),边缘校正好些,握感也好些.

都没有用过，不过根据BVD的评测，Nikon更好一些：what are the mid-sized LXs like? Shrink the LX body by about half, keeping the flared top to fit the hands, the screw in, screw out eyecups, the elegant locking diopter ring, and the exceptionally responsive focus control—and then pack in LX quality optics, and you have the 8x32 and 10x32s. Both offer exceptionally bright and sharp views, surpassing the Leica and approaching the Superior E. Most obvious, when compared to the Leica, is the evenness of the illumination across the field. The Leicas have always had a hot spot in the center (or a shadowed ring around the center, which ever way you look at it) that is particularly evident when looking at birds against the sky. The Nikons are clear right out to the edge. The LXs also have much less distortion at the edges of the field than the Leicas. Straight lines (tree trunks, telephone poles, etc.) stay much closer to straight than in the Leicas. Even chromatic aberration is kept to a minimum except at the extreme edges of the field. Both mid-sized LXs offer absolutely stunning color fidelity and all the detail you are ever likely to want.

articularly noteworthy are the fields-of-view. The 10x has a 6.5 field (341 feet at 1000 yards). That would be a generous field in an 8x glass and, along with the LX’s exceptional handling, makes the 10x a much better choice for day-in-day-out birding than most other 10x glasses on the market.
 
 The 8x32 LX has a field of 7.8 degrees (409.5 feet at 1000 yards), exceptionally wide for any glass. It is “picture window” view that could easily become addictive (The Superior Es match the field of the LXs and that is one of their major attractions as well.)
 All in all, the new Nikon Venturer LX 8x32s clearly set a new standard in mid-sized roof-prism glasses, replacing the Leica 8x32s as the BVD Reference Standard in their class.
 
 The 10x LXs earn a BVD “Product of Special Merit” award. While 10x glasses are not for every birder, those who are attracted to the high power view (and can handle the extra care and fatigue inherent in using high power glasses) will find the LXs to be everything they always dreamed of in a compact birding glass.

 几只8×32望远镜，从左至右：Pentax DCFWP，Minox，Leica，Nikon Venturer LX,B&L
 简单翻译一下上文：
 这种中规格的LX会怎么样呢？把原有的LX（42mm)缩小，保持原有的漏斗型上部镜身使其适合手型，旋入/旋出眼罩，精巧的屈光度锁定装置，以及非常灵敏的聚焦控制－－所有LX系列望远镜的特征，只是规格变为8×32和10×32。他们都有出奇明亮和锐利的图象，超越了Leica而接近Superior E系列。最明显的是，与Leica相比，视场的亮度更为均匀。Leica总是有中心的高亮区和周围的暗影。在对着天空观看时尤为明显。Nikon显然是有优势的。LX同样在边缘的变形更小，直线在其中比Leica更直。甚至色差也被控制在最小范围－除非是在视场边缘。两只LX都提供了极好的色彩以及所有您想要得到的细节还原。
 10×32的6.5度和8×32的7.8度视场都非常之大（－－不过不要太在乎视场大小，其实都没有贝格式大）10×32对于那些只在白天观测而又喜欢高倍的人非常适合。而8×32则将作为我们新的中规格屋脊棱镜望远镜测试基准，取代原来的Leica 8×32。

值得研究了

hengheng · 发表于 2002-12-13 00:04

NIKON8*32的大小和LEICA的7*42体积差不多大了~~
 是这样吧~？

没有那么大吧，看上面的比较图，比Leica 8 ×32大一点

VLX外观比较奇特，多出来的尺寸主要是一些突出的边角，但是由于此设计握持非常舒适，Leica的棱镜安放比较特殊，外形比较圆滑紧凑，但是握持感觉就差远了。

这东西现在大概多少钱，再哪能买到？

funder · 发表于 2002-12-14 00:26

只能从境外买，600美元左右

hengheng · 发表于 2002-12-14 01:07

香港也没有吗？
