I'll be damned Here comes your ghost again But that's not unusual It's just that the moon is full And you happened to call And here I sit Hand on the telephone Hearing a voice I'd known A couple of light years ago Heading straight for a fall
As I remember your eyes Were bluer than robin's eggs My poetry was lousy you said Where are you calling from? A booth in the midwest Ten years ago I bought you some cufflinks You brought me something We both know what memories can bring They bring diamonds and rust
Well you burst on the scene Already a legend The unwashed phenomenon The original vagabond You strayed into my arms And there you stayed Temporarily lost at sea The Madonna was yours for free Yes the girl on the half-shell Would keep you unharmed
Now I see you standing With brown leaves falling around And snow in your hair Now you're smiling out the window Of that crummy hotel Over Washington Square Our breath comes out white clouds Mingles and hangs in the air Speaking strictly for me We both could have died then and there
Now you're telling me You're not nostalgic Then give me another word for it You who are so good with words And at keeping things vague Because I need some of that vagueness now It's all come back too clearly Yes I loved you dearly And if you're offering me diamonds and rust I've already paid
D型镜头:Distance 焦点距离数据传递技术 代表镜头可回传对焦距离信息,作为 3D(景物的亮度,景物对比度,景物的距离)矩阵测光的参考以及 TTL 均衡闪光的控制。1992年推出。代表镜头:28-105mm f/3.5-4.5D AF Zoom-Nikkor
CRC:Close Range Correction 近摄校正 采用浮动镜片设计,保证近摄时光学素质不下降,例如AIS 24/2.8、AF 85/1.4D IF之类均采用了CRC技术。
DC : Defocus-image Control 散焦影像控制 尼康公司独创的镜头,可提供与众不同的散焦影像控制功能。镜头的前端有一个散焦定位转环,该环上的光圈值从F2到F5.6共4挡,分别标在环的左右,用R(后景散焦)与F(前景散焦)来指示。这是一种特殊的定焦镜头,其最大特点在于容许对特定被摄体的背景或前景进行模糊控制,以便求得最佳的焦外成像,这一点在拍摄人像时非常有价值,它还可以帮助我们根据所想要表现的来控制照片的各个部分,这也是其它厂家同类镜头所无法比拟的。目前尼康只有2支DC镜头:AF DC 105mm f/2D、AF DC 135mm f/2D
ED : Extra-low Dispersion超低色散镜片 是指这支镜头内含 ED 镜片,最大限度降低镜头色差(chromatic aberration),从而保证镜头有优异的光学表现。代表镜头:80-200mm f/2.8D ED AF Zoom-Nikkor
G型镜头 与D型镜头不同的是,该种镜头无光圈环设计,光圈调整必须由机身来完成,同时支持3D矩阵测光。这样的设计减轻了镜头重量,降低了生产成本。该种镜头与F5、F100、F80、F65、F60、F55、F50、F401、PRONEA和D1机身完全兼容,对于F4、F90\F90X、F70、F801和F-601等机身,只能使用程序曝光和快门优先曝光模式。与剩下的其他机身不兼容。G型Nikkor镜头操作更为简便,理论上没有误操作,因为它无需手动设置最小光圈。这是塑料AF镜头的延续,针对那些几乎从不手动设置镜头的摄影者。现在Nikon有将G型头推广的趋势。代表镜头:28-80mm f/3.3-5.6G AF Zoom-Nikkor
IF : Internal Focusing内对焦技术 所谓内对焦是指镜头在对焦时,前后组镜片都不移动,而由镜头内部的一个对焦镜片组(focus lens group)的浮动来完成对焦,对焦时镜头长度保持不变。IF技术的采用使快速而安静的对焦变为可能。代表镜头:85mm f/1.4D IF AF Nikkor
