特殊玻璃
由最昂贵的光学玻璃制成的透镜,象纯金一样,是按照重量计价的。设计师寻找的通常是高折射率低色散玻璃。色散使不同颜色(频率)的光线聚于不同的焦平面,这显然影响了锐度。将所有颜色的光线聚在同一焦平面,就是镜头光学设计设计中的“色差校正”。能做到这样的镜头被称为“achromats”或“achromatics”,意为“无色”。
实际上,“无色”镜头只是把红光和蓝光聚于同一平面,还有很大的校正空间。而“apochromat”(“away from colour”)可以把红、绿、蓝光聚于同一焦点,是成像锐度显著提高,这也是为什么很多镜头广告在宣传“Apo”。由于对于摄影镜头的消色差还没有严格的定义,因此很难不怀疑有些镜头的消色差比其他更好。类似的,尼康的“ED”(极低色散)显然是指ED镜头中使用的特殊玻璃。但玻璃怎样才变得特殊呢?
很少镜头使用玻璃以外的材料。实际上,萤石由于独特的光学性质被使用。然而,萤石镜片非常贵,也非常脆弱,一此极短的冲击就能令它破碎,并且如果不与空气隔绝的话,它会逐渐分解。如今,萤石已被特殊玻璃取代(除了在不计费用的军用镜头中)。
树脂不适于制造高级镜头,通常用于廉价镜头。但是Tamron曾推出的将树脂覆盖在玻璃上的“混和非球面”镜头却很特别。
大曲率
镜片的曲率约大,制造成本越高。大曲率的优势在于,与高折射率低色散玻璃配合时,可以代替两或三片普通透镜。对于一些超广角镜头和变焦头,曲率非常大的曲面是最好的设计。
非球面
绝大多数镜头使用的只是“普通”球面的透镜。虽然研磨非球面也是可能的,如抛物面或双曲面,但更昂贵。非球面的使用也可以减少透镜的总数:一个非球面透镜可以达到两个球面透镜的效果,或多个非球面镜可以达到球面镜不能达到的效果。
任何时候,非球面镜头都是屈指可数的,他们通常是同样的球面镜头价格的两到三倍。通常只有大光圈镜头使用非球面镜,并且通常只有一个镜片使用非球面。
随着镜头设计和玻璃制造的提高,非球面变的越来越不必要。然而,Tamron的“混和非球面”镜头提供了很好的校正,又避免了树脂的缺点,也许是非球面在为了存在的唯一方式。
〖现在非球面镜好象使用还是很多。作者十年前的观点有其局限性。随着技术的发展,非球面镜的制造成本应该也降低了吧?〗
反差和透镜数量
你现在可能认为,使用足够的透镜,正确的种类和正确的形状,就可以制造几乎任何镜头。大体上来说,就是这样。但一个不能逃避的事实是,更多的透镜,意味着更低的反差。虽然多层镀膜可以大幅度减小镜片表面的反光,但还无法完全消除,这些反射的杂光降低了反差。
早期无镀膜镜头在每个镜片表面可以反射百分之五到十的光线,这就是为什么要尽量减少镜片空气接触面的数量。比如,Zeiss 50mm f/1.5 Sonnar只有六个镜片空气接触面,而Leitz 50mm f/1.5 Summarit有十个。Summarit分辨率更高;但Sonnar的反差更大,以至看起来更锐利。
如今镜片表面的反光率只有大概百分之1.5到0.01。廉价镜头的镀膜效果也较差,而昂贵镜头虽然有较多镜片,但镀膜质量也更高,使得反差更高。
镀膜使用了光的“干涉”原理,镀膜的厚度必须是光波长的四分之一。显然,一层镀膜只能减弱一种波长(颜色)光线的反射。多层镀膜可以减弱多种波长光线的反射。不管其他厂商怎么说,Leitz看起来应该是最早使用多层镀膜的厂家,在五十年代晚期。
镀膜和多层镀膜似乎使遮光罩失去了以往的重要性,但有些情况下好的遮光罩仍然可以产生惊人的效果。理想的遮光罩应该适于底片的长宽比,并且可调长度。这在大中幅设备中很普遍,但在35毫米系统中几乎没有。有些人把中幅机的遮光罩用在35毫米镜头上。
〖在可能的情况下,尽量使用遮光罩,有益无害。〗
制造工艺
无论你的镜头设计的多么好,理论上能到达多么高的水平,如果制造不当,一起都前功尽弃。精确的镜头到胶片距离是最明显,也是最容易做到的。还有,镜头的组装必须达到不可想象的精确;所有镜片的轴心都必须完全吻合;每一个镜片都必须精确的固定在镜桶上。固定必须非常牢固,不然镜头掉落或受到碰撞时就会改变结构。一支昂贵的镜头将得到非常精密的组装,以及在每一步的测试和试验。一支廉价镜头可能轴线没有完全对齐;或者虽然对齐了,但在日常使用中的碰撞就可能倒置镜片位移。(也就是不抗造。一分钱一分货的道理。)
对焦机构必须精确和顺畅,并且耐用。光圈和叶片,以及相连接的机构也必须顺滑。所有螺丝和压环必须拧紧,并且保持不变。廉价镜头比昂贵的镜头更容易松动,虽然很大程度取决于你怎样保养镜头。比如说,骑摩托长途旅行,肯定对镜头不利。
〖好镜头不只是成像优秀,也要耐用,要经得起岁月的考验。〗
材料
与使用方式比起来,镜头卡口使用的材质并不太重要。即使塑料也没什么不可以,因为那毕竟不是轴承表面,并且如果它的强度足够应付日常的积压和拉伸。轻金属合金可以替代黄铜,如果它们做得当的表面处理(通常是电镀),但钢(除了不锈钢)应该谨慎使用,如果有腐蚀的可能。对于接触面,特别是卡口,较硬的材质如不锈钢或厚镀层的黄铜,显然要比裸露的黄铜或轻金属合金更合适。
一个常识是,耐用意味着重量,虽然有很多中方法可以不使用黄铜制造耐用的镜头。一个真正优质的镜头如果正常使用,可以用上几十年,即使是专业人士的粗暴使用。一个廉价镜头,虽然刚开始还不错,但无法保持那么久。
分辨率
分辨率,即一个镜头可以表现的细节的多少,显然非常重要,并且基于平均的视力和图片尺寸,很容易设定锐度的标准。正常视力的人可以分辨约一分的弧度,或大约相当于在3米的距离看到白背景上的黑头发。使用传统摄影术语来讲,约等于在25厘米的距离观看照片上的8线对/毫米。因此,从扩印照片时的放大率就可以大致计算出底片上需要多大的分辨率,也就是用放大率乘以8 lp/mm(线对/毫米)。比如4×6英寸照片是4倍放大率,所以在底片上需要4×8=32 lp/mm的分辨率;6倍放大率(即8×10英寸或20×25厘米照片)就需要48 lp/mm。
〈“丢失”与“多余”分辨率〉
在实际中,我们需要底片上的分辨率比上面的计算结果要稍微高一点,因为放大过程中要损失一些锐度;并且放大率越大,需要的“多余”的分辨率就越多。因此,如果理论计算需要32 lp/mm,那么实际上有35-40 lp/mm就应该可以;但如果理论上需要底片上有64 lp/mm,实际上可能需要80 lp/mm。很大程度取决于放大镜头,以及放大时对焦的精确;而对于扫描底片,扫描仪类似于一个完美的放大机,因此在过程中损失的分辨率较少。胶片本身也很重要,慢速、细颗粒的胶片比高速、粗颗粒胶片的分辨能力更强。
〈衍射限制的分辨率〉
然而,分辨率在理论上还受到绝对的制约。撇开深奥的理论不说,一个明显的定律就是,衍射对分辨率的限制,以lp/mm为单位,在百分之五十的反差,分辨率的顶限是1000/n,这里n是光圈值。因此,在f/2衍射限制的分辨率是500 lp/mm;在f/4为250 lp/mm;而f/8就限制在125 lp/mm。实际上,100 lp/mm或稍微高一点,是普通用途胶片可以记录的最高分辨率,即使是用来获得最高的锐度。1000/n定律也解释了为什么35毫米相机的镜头很少用小于f/16的光圈,因为在f/16分辨率已经限制在62.5 lp/mm。在f/22时,降低到45 lp/mm;而f/32时只有31 lp/mm。
另一方面,我们可能太注重这些数据了。其实45 lp/mm已经给予6×9英寸照片可以接受的效果,虽然再小的分辨率就可以看出差别。并且1000/n从理论上来讲可能被认为太苛刻,即使1500/n在某些情况下被认为是刚刚合适的标准。
〈分辨率与观看距离〉
为了制作一张16×20英寸(40×50厘米)的照片,一张35毫米底片需要放大约16倍,但128 lp/mm在底片上却是不可能的。然而,通常我们不会在25厘米的距离观看这么大的一张照片,很可能是在至少两倍的距离上观看。这使得分辨率的标准随着观看距离而改变,因此两倍的观看距离将使需要的分辨率减少一半,即64 lp/mm。这里很容易看出,为什么35毫米相机可以如此流行,因为它在各种情景下都刚好适应了这个“真实世界”的需求。
〈分辨率和片幅〉
仍然使用上面16×20英寸的例子,如果底片是6×7厘米,只需放大约7倍。即使我们仍坚持照片上8 lp/mm的标准,底片上也只需要56 lp/mm而已;而且如果我们可以接受照片上的4 lp/mm,那么底片上只需要28 lp/mm的分辨率。如果我们使用4×5英寸的底片,放大率只有4倍,那么底片上只需32 lp/mm(严格标准)或16 lp/mm。这不只演示的大幅底片的显著优势,也同时解释了为什么大幅机的镜头可以收缩到比35毫米镜头更小的光圈。如果4×5底片上需要16 lp/mm的分辨率,那么用f/64才使衍射的限制刚刚达到。这也解释了另外一件事,就是一些镜头是怎样同时适用于35毫米和中幅相机的:当装在35毫米相机上时,使用的只是镜头像场的中央部分,也就是分辨率最高的部分;而当装在中幅相机上时,像场边缘的分辨率虽不高,但已经够用。
有了这些数据,你可以对分辨率图表加深理解,但分辨率不应被单独考虑。
反差
想象两支镜头同样拍摄64 lp/mm的标板,但反差不同。反差高的镜头成像是白和黑,而反差低的镜头成像是淡灰色和深灰色。高反差镜头的成像看起来更锐利。
这没有什么吃惊。令人吃惊的是,虽然高反差镜头的成像看起来更锐利,但低反差镜头可以到达更高的分辨率,比如80 lp/mm。前文提到过,在30年代,Leica镜头偏重于分辨率,而Contax镜头倾向于高反差,这就导致的双方支持者的论战。双方都说自己的镜头更“锐利”,当然,他们说得都对,或者说,都错。
这主要取决于镀膜,但也与新型玻璃或者新的光学设计有关。现代的镜头比早期镜头有更高的分辨率和更大的反差。但即使如此,分辨率和反差仍然需要折衷。镜头的镜片越多,反差越低,仍然是不变的定律,原因已经说明。
眩光和鬼影
“眩光”可以指两样东西。有些镜头是由于内部反光问题,被称为“flary”(意为闪耀着亮光,就是我们通常说的镜片反光白花花的)。但是,通常眩光是指内部反射依然可见,而不是指导致劣质的成像。典型的,眩光将导致高光向外溢出,因此亮部周围通常会围绕着一种光辉。也有时镜头会产生一个主像和一个附属的“鬼影”,比如日光灯管或路灯。现代的镀膜技术使其不再是一个大问题,但偶尔还是会发生,尤其是廉价的变焦镜头和超大光圈镜头。去除滤镜能减轻类似问题。
一种常见的内部反射是当光线直射入镜头时,产生光圈形状的影像。有些人喜欢这种效果,但有些人讨厌。对于内部反射,一个设计合理的较深的遮光罩将能有效减轻眩光和鬼影。
〖遮光罩的作用其实有限,当顺光拍照或光源直接出现在画面中时,遮光罩基本没什么作用,只有当光线从前方斜向射来时,遮光罩的用处才最大。不过一直戴着绝对没什么坏处。〗
场曲
很少有镜头能把一个纯平的景物投射到一个纯平面上。相反的,它们会形成一个弯曲的或碟状的成像:中央距离镜头最远,边缘较近。有些早期相机为了配合这一点,将胶片平面做成曲面。不过,通常上,设计者尽量使镜头的像场更平,使其可以在平整的底片上的成像可以接收。
场曲是导致镜头成像从中央向四周逐渐变差的原因之一,这在超大光圈镜头和变蕉镜头上更严重。对于单反相机,通常以画面中央对焦,因此边缘可能会变软,但如果边缘没有什么主体的话,这就不成问题。
底片的平整
前提到过镜头成像在“平整”的底片上。有些相机的底片比其他的要平整很多;然而,不平整很可能会帮助提高锐度。如果把机身装上废片,使用B或T门从前方看,可以发现底片有一点点弯曲。如果碰巧的话,这刚好符合了像场的碗或碟状弯曲。这可能就是为什么战前的Leica比它能够达到的还要锐利:底片不是绝对平整,并且Elmar镜头的像场弯曲,两者似乎可以经常完美结合。但有些机器的底片会比其他平整一些,这也就是旧Leica的个体差异大的原因。
畸变
主要有两种,即桶形畸变和枕形畸变。传统上,广角镜头会产生桶形畸变,鱼眼镜头是利用桶形畸变的例子;远摄镜头通常产生枕形畸变;廉价(或早期)变焦镜头可能两种都有,在广角段产生桶形畸变,在长焦端是枕形畸变。
如果你拍摄边缘有直线的景物,畸变就很容易被察觉。但通常你很难在取景器里发现,因为有时取景器本身的光学系统也是有畸变的,不过畸变确实产生在底片上。当然,严重的畸变可以从取景器中观察到。
〖广角镜头的畸变〗
使用24毫米或更广的超广角镜头,在边缘的圆圈将变成椭圆。使用网球可以很明显的验证,正如许多摄影书籍中的例子;但是当一个人的头产生这样的畸变时,可能会很恐怖。
对于这种畸变你无计可施,因为这是光学角度过大造成的。弯曲的焦平面可以解决这一问题,很难做到。绝大多数设计者都选择放弃寻找正确的像场弯曲度,而愿意保存这种危害不大的广角畸变。
照度
一支完美的镜头,像场各处的照度都是相同的。一个长焦镜头(非远摄结构)像场中照度的不均匀可能很难察觉;但对于广角镜头和一些变焦镜头的某些焦段,可能很明显。
成像边缘失光(暗角)可以由两种原因造成。一种是机械遮角,即由镜头的结构造成的:光线进入镜头的角度越斜,被透镜边缘、镜头卡口或内部遮挡的就越多。大的前组和后组镜片可以减轻这种遮角,这也是为什么一些变焦镜头的暗角很严重:为了体积和便携,成像照度被用来进行折衷。
另一种叫做cos4暗角,这个名称是因为一束光照射在一个平面上的亮度与入射角的余弦(cos)的4次方成正比。对于传统超广角镜头(非反远摄结构),成像边缘的光线相当斜,照度也随之减弱。解决cos4暗角的唯一方法是使用一种渐变滤镜,中央深色,边缘浅色。具我们所知,只有一只35毫米镜头使用过这种系统,就是Zeiss Hologon 15mm镜头,一支极少见的收藏品。
未知因素
即使你考虑了以上所有因素,以及一些含糊不清的技术,镜头制造中仍有一小点魔力。对此曾有过多种多样的表达。我们的祖父曾谈起过一些镜头的“Plastic rendition”,意思说照片有三维空间感(当时“plastic”的意思)。现今,我们可能会说某一镜头有很好的“层次”(gradation)感,虽然,当被追问时,我们也很难解释那到底表示什么。但是,无可质疑的,确实有些镜头有着特殊的魔力,其中我们拥有的就包括了一支21mm f/4 ‘mirror-up’(使用时需锁上反光镜) Nikon;另一支21mm f/4.5 Zeiss Biogon;以及一支(大画幅)150mm f/6.3 Tessar。这种“魔力”甚至在同一款的不同个体上都不一定存在,但当你发现时,你会意识到。

14×17″ ULF Lens Recommendations
Over the past year, I’ve been building a lens collection to use with my new Chamonix 14×17 view camera. Normal (being 560mm on this format) and wider lenses are relatively easy to find. But its at the longer end of the spectrum that the choices become more varied and its harder to make a decision. So I started by buying what I call the ULF “Holy Trinity” of modern shuttered lenses that is just about in arsenal of every serious ULF user shooting sizes above 11×14: G-Claron 355mm f9, Nikkor M 450mm f9, and Fujinon C 600 f11.5. They are relatively lightweight, small enough to fit on a Linhof Technica lensboard, have manageable filter sizes, and cast usable image circles far in excess of what is quoted by their manufacturers. Of the three, only the Fujinon C 600mm is hard to find these days.
Lens | Focal Length (mm) | Max Aperture | Image Circle (mm) | Shutter | Filter Size (mm) | Wieght (g) | Market Price |
G-Claron | 355 | f9 | 444 | Copal 3 | 77 | 855 | $550-700 |
Nikkor-M | 450 | f9 | 440 | Copal 3 | 67 | 640 | $800-1000 |
Fujinon-C | 600 | f11.5 | 620 | Copal 3 | 67 | 575 | $1200-1600 |
Now if your budget won’t allow for the “Holy Trinity” there is a “Second String” worth considering. The added bonus is these lenses are a little faster but they are heavier, need to be on Sinar or larger lensboards, have bigger filter rings and usually come in older Compound 5 or Ilex 5 shutters. The Symmar Convertible is particularly interesting since it can do double duty at 360mm and 620mm, potentially making it the only lens you will ever need – assuming your front standard can take almost 2kg or 4.2lbs of weight. The B&L lens is somewhat hard to find pre mounted in a shutter but more common as a barrel. Goerz Red Dot Artar 24″, Apo-Nikkor 600mm or 610mm and Apo-Ronar 600mm are all pretty much interchangeable. I would pick up the first one you find in an Ilex 5 or Copal 3 shutter.

* Misses maximum aperture by 1/3 stop
Now to get a real jump up from 600mm to make a difference in perspective I would suggest you want to go up to 30″ or 760mm. Personally I looked for more modern lenses that could be found in a shutter or at least mounted in one. Many process lenses can be shutter mounted and made to work. Sometimes this results in a small loss of speed of 1-2 stops as the shutter constricts the aperture but its not usually material. Older process lenses can be made in brass and be extraordinarily heavy. Likewise, their sheer bulk can make it hard to mount on a smaller lensboard and fit on a ‘modern’ shutter like a Copal #3 or more likely an Ilex #5. So in practical terms if the lens can be shutter mounted it will fit on a Sinar board of 5.25″ square or larger. Once you have found your barrel lens, you will need to buy a shutter, a flange and a lensboard.
Shutters are often easier to buy attached to a lens. The 375mm f6.3 Ilex-Calumet Caltar is a particularly unloved lens that comes in an Ilex #5. Remember that the Ilex 5 came in several flavors, starting from the left in the image below: Kodak branded (avoid due to smaller aperture and mount), Black (avoid, oldest version), Silver Older (look for this one), Silver Newer (this is the best). Then there is one more kind, the “Syncro Electronic” that can only be fired with an electronic voltage and is basically useless otherwise.
Left to right: Kodak Ilex#5, Black Ilex#5, Older Silver Ilex#5, Newer Silver Ilex#5
Similarly the Copal 3 comes in two sizes the 3 and the smaller 3S. Avoid the 3S as it has a smaller maximum aperture size. The regular Copal 3 comes in three versions starting oldest first: small tooth rim in silver, wider smoother tooth rim in silver, and finally black. If possible go for the black version or second best silver with wider smoother tooth rim, avoid the the other two versions.
Front left to right: Copal 3S, Copal 3 Silver Small Teeth, Copal 3 Silver Big Smooth Teeth, Copal 3 Black
Then you need to get the barrel mounted to the shutter and lensboard by an machinist like SK Grimes which usually charges around $350-450 for the honor. At the same time as you have the mounting done, I recommend that you ask your machinist to put some threads on the lens front element (if there are none) and make you a new front lens cap. The reason being that most process lenses don’t come with filter threads and it can be hard to find a good fitting cap for your custom set-up. Often you have the option of a small range of filter sizes – say about 5mm plus or minus. So if possible try and standardize on some favorite sizes – like 67mm, 77mm, 95mm or 105mm.
Left to right: Symmar Convertible 360/620 f5.6/12 in Compound 4, 30″ Red Dot Artar f12 in Copal 3, and 35″ Red Dot Artar f12 in Ilex #5
The most common lenses to shutter mount are the APO-Nikkor, Rodenstock Ronars and Goerz Red Dot Artars. The APO-Nikkors get huge after 760mm and can’t reasonable be shutter mounted beyond that focal length. Rodenstock makes the regular APO-Ronar and a compact APO-Ronar-CL line of process lenses. After 760mm the most sensible lenses to choose are the Goerz Red Dot Artars but you really want an aluminum version from after the late 1960s not an older brass one because of the weight penalty. The weight penalty can be offset through shutter mounting since much of the brass barrel is discarded in the process. The Carl Ziess / Doctar Apo Germinar lenses in 750mm and 1000mm come in barrels and a native Copal 3 mount. They are some of the most modern processes lenses available but they are apparently hard to cut out of the barrel and shutter mount on an Ilex #5. Then there is of course the Schneider 1100mm f14 Fine Art XXL which even if you had the $3-5k to buy it is hard to find. Many of the longer, and some of the shorter, lenses on this list are over 3 Kg and would put a real strain on most field cameras. So while they could be feasible mounted on a shutter you are probably better off with one of the sub-3 Kg options.

* Will lose 1 or more stops of speed when mounted. For example, a 35″ Artar goes from max aperture f12.5 to f19 in a Copal 3.
Now if you are content to use a barrel lens without a shutter or have a Packard shutter of the right size lying around then you might want to consider the lenses in the “Super Long / Heavy / Big Barrels” list below. Most of the lenses are too big to mount on a Sinar board and weigh so much that they would put a real strain on just about any front standard, but hey, with lenses this size and the bellows requirements this long you are probably thinking of mounting it on the side or end of a delivery truck! Right?

Cheaper than the more modern process lenses list above, would be to use an old process lens from one of the former major lens makers. Allen Rumme’s site has an extensive list of process lenses of which a bunch would work for 14×17 format. In particular look at the Ross Apo Process (coated) and Apochromat Xpres (coated) lenses from 21″ to 48″ and the Taylor Hobson Cooke Series IX Apochromatic (coated), Cooke Series Vb Process, and Cooke Process lenses also from 21″ to 48″. I wouldn’t consider mounting these lenses on a shutter but simply using them in a barrel stopped way down to get long exposure times you can manually execute.
By necessity this series of tables is incomplete in places. I don’t own many of these lens myself. If you have any of the missing data please leave a comment below. It will be much appreciated and a big help to the 14×17″ ULF community
這顆 1000mm / 100 度的鏡頭,是有位朋友訂製的,要用在 20×60 英吋的相機上
在毛玻璃上,影像還 OK,至於實際拍攝,因為相機還在製造中,還得等一陣子
鏡頭是 periscope 二片式設計,鏡片是 acrylic,鏡片直徑 172mm,鏡筒是鋁的,前緣直徑 300mm
這顆的影像圈超過2米,若有需要更大的,3米甚至4米,應該可以依樣製造
