}Nikon's 10 Worst Lenses 尼康的10个最差镜头2008年7月Introduction导言For a lens to be awful it has to be a failed dream. Crappy optics alone won't get it here. For instance, the first 50-300mm f/4.5 lens of 1968 was among Nikon's least sharp lenses ever, but we expected that from the zoom which also was the world's widest-zoom range lens ever made for 35mm SLR cameras. (The recent 50-300mm f/4.5 ED is a different and excellent lens.)对于一个镜头来说，蹩脚的光学表现就是一个失败的梦想，这是很可怕的。
例如，1968年发布的第一只50-300mm f/4.5镜头是尼康最不锐利的镜头之一，但我们预计，这也是世界上最大变焦比的35mm单反相机的变焦镜头。
（新版的50-300mm f/ 4.5 ED则是一款优秀的镜头。
）An expensive, exotic lens is even more of a dud when its optics don't measure up to older and less expensive lenses.一只昂贵的、奇特的镜头，当他的光学设计不及过去的廉价镜头时，更是一种悲剧。
These are in no particular order. All these cover FX, DX and film.这些镜头没有特别排序，包括了FX、DX格式和胶片镜头。

Nikon's 10 Worst Lenses尼康的10个最差镜头Even lenses that aren't very sharp can be used to make incredibly great photos. However, as lenses go, these are the pigs at Nikon's party.即使不是很锐利的镜头，也可以用来拍摄出很成功的照片，然而，这几只镜头，却是尼康镜头同类中的不和谐音。
Given any of these lenses I could go make images as good as any of my others. As lenses go, each of these isn't just me saying they are duds; for each one, plenty of others have confirmed my observations. These are all this bad.给我这些镜头中的任意一只，我都不能拍摄出比其他镜头好的照片。
它们之中的任何一只，不仅是我在说它们糟糕，很多人都证实了我的看法：这些镜头都不好。
43-86mm F(1963-1976) {尼康F胶片单反相机用变焦镜头}Nikon 43-86mm f/3.5 F.The original Nikon 43-86mm is the worst lens Nikon has ever made.最初的Nikon 43-86mm是尼康生产过的最差的镜头之一。
It's worse than the worst, because not only is it terrible by itself, it was so awful that it has tainted the reputation of all other zoom lenses to this day.没有最差只有更差，不仅因其劣质，它已经玷污了所有其他变焦镜头的声誉。
What makes it so bad? It's Nikon's softest lens, and is loaded with untold levels of distortion. It also has awful flare and ghosts.差到什么程度？这是尼康最肉的镜头，伴随着各种各样的失真，还有很严重的耀斑和鬼影。
How bad it was! Ghosts everywhere!!! (D3, 43-86mm f/3.5 F at f/8)糟透了!到处是鬼影!!!（机身D3，镜头43-86mm f/3.5 F，光圈f/8）When people say zooms aren't sharp, zooms flare, and zooms have a lot of distortion, it is because this horrible lens set these expectations.当人们说变焦镜头成像不锐利、有耀斑、多畸变时，就是拜这只该死的镜头所赐。
The 43-86mm came in two versions. This first horrible version has the lettering inside the filter ring. The later version (1975-1982) is a completely different lens, and is just fine. It has its lettering outside the filter ring.43-86mm镜头有两个版本，早期版的刻字在滤镜圈内，后期版(1975-1982)的刻字在滤镜圈外，是一款很好的镜头。

The embarrassing part is that it cost $1,300 new (at full NYC discount), and still sells for about $800 used, and it's much worse than Nikon's older 18mm lenses.这是尼康有史以来最烂的18mm镜头。
令人尴尬的是，它的成本是1,300美元，全新品在纽约竟然只能卖到800美元左右，并且它比尼康老款的18mm镜头更糟。
It uses every trick Nikon knows, and is worse than earlier lenses!它千方百计地宣称，它比早期版本更糟！The 18mm f/2.8 D AF uses internal focusing and aspheric elements, and somehowwinds up being softer and having more distortion than Nikon's original 18mm f/4,18mm f/3.5 AI-s, or their current zooms. It has a lot of falloff wide-open, too.该18mm f/2.8 D AF镜头，使用了内对焦和非球面镜片，柔性收尾，较早期的18mm f/4和18mm f3.5 Ai-s等变焦镜头畸变大，图像衰减也更大。
As we politely refer to a morbidly fat person as "having a slight weight problem," this 18mm lens has a slight ghosting problem. It has more ghosts than any other 18mm lens, and probably more ghosts than any other Nikon lens except the original 43-86mm above. I have no idea why it's so bad, but it is. This 18mm AF is one of the very few lenses for which I would use a hood. Good luck if you get stuck buying a used one without its original HB-8 hood; these hoods are now impossible to buy new or used.正如我们将特别肥胖的人委婉地称为“有轻微的体重问题的人”一样，我们说“这只18mm镜头有轻微的鬼影问题”。
它比任何一只18mm镜头有更多的鬼影，比尼康的其他镜头的鬼影更严重，或许只有上面提到的43-86mm除外。
