i50mm

一个会拍照的镜头盖

最近听羽说，他整了一枚可以装在徕卡上的饼干头，来自傻瓜机改镜站的30mm F/10，而且还乐此不疲的拍了不少。

镜头装在徕卡机身上跟镜头盖一般大小，哈哈，太逗了。不仔细看还真以为是镜头盖。带着这头出街，会不会被人以为这小子是不是忘记装镜头了，顶着机身盖就出门啦。哈哈。

画质竟然不错呦

哈哈，起初大家都觉得有点“奢侈”，特别是装在胶卷前。羽把他的照片发出来了，嘿，不错呦。真想不到黄豆粒大小能出片。而且他不光在室外，室内也能拍。但毕竟f10光圈，还是室外更保险。色彩还真像那么回事，除了边角画质外，大部分画面都还可以呀。翻看森山大道店画册，他用理光gr画质也不过如此哦。

后来才听说，原来这枚饼干头是人家diy改镜做出来的，把老傻瓜机的镜芯改装到镜头盖上了。不是那种用个塑料片对付的lomo相机哦。这也说明一个事实，胶片时代，再傻的傻瓜机它也是全画幅。

88元diy的乐趣

当然了，用得起徕卡机身的人绝大多数都用得起徕卡镜头，那这个88元的镜头有存在意义么？我想还是有滴。

1、街头浪摄流。

经常有些人街头摄影就是把镜头缩小到f16的光圈，既然如此，那么这枚30mm F/10的饼干头可以偶尔让你体验一下森山大道的赶脚，而不用花好几千购买那个理光gr。

2、做一个奢侈的机身盖。

是的，用徕卡的人往往都不止拥有一台机身，也就是不差钱儿，用88元的镜头是不是太跌份儿了？要反过来想，看看你柜子里那几台徕卡m3、m2、m4、m7还有几台数码m机……是不是顶着10块钱的镜头盖？配一个88元的镜头盖是不是挺奢侈的。啊哈哈。

3、diy的乐趣。

哈哈，同事在拼多多上整了个18块钱的仿苹果的无线蓝牙耳机，说音质简直垃圾，扬言再也不信拼多多了，i50mm手上正好有个正准备扔掉的断线耳机，于是把单元给他换到那个18元的耳机上了，哇塞音质感人，超过啦苹果原厂耳机，把同事激动的合不拢嘴，天天带着……。这种diy的乐趣有时候就是玄妙。

PREFACE 

THE LEICA COLLECTORS GUIDE 

( IllustratedLeica Index )

The illustrated index of the Leica Code Word List has been compiled owing to the demand for an illustrated quick reference guide to the Leica system .

Over the years we have reprinted a number of Leica catalogues ,however ,to find a particular reference it has meant leafing through many pages and books .When Leica -TheFirst Fifty Years was produced it was not intended to include many of the accessories or lenses ,therefore they were included in the book at the end .The prime concern of Leica -The First Fifty Years was to illustrate and list the cameras produced .The above reasons were the main purpose for the compilation of this handbook .

The basis of this handbook was the complete Code Word List as detailed in Leica -TheFirst Fifty Years which covers over 2 000items ,a large majority of which were included for completeness .Obviously one would not illustrate all similar items ( i.e.one is aware of the many filter variations ,colour ,size ,finish ,fittings ,etc .,the same applying to projector sundries ),which in their own right could well account for some hundreds of code references .Therefore one is left with a nucleus of cameras ,viewfinders ,closeup accessories ,darkroom equipment ,etc .,and these we have endeavoured to illustrate in this handbook .Again one can get an instance where five codes would illustrate the same camera but with different lenses .In this case one example is illustrated ,and missing illust rations show the same camera with a different lense .( Ratherthan show separate headings under individual code words we have amalgamated them together under the camera body ).As one will note the cameras only occupy a small part of this handbook ,therefore allowing for greater coverage of the Leica Accessories .For example ,in the close -upand copy equipment chapter (thisbeing the largest section of this book )we have included innumerable items that have only appeared in specialised reference catalogues ,such items not being normally available to the individual .Other sections cover rangefinders ,accessories and lenses .

We are sure that the Leica Collectors Guide will prove a most useful reference for the Leica enthusiast .We do realise that this edition does not include every item ,as it has been very difficult to find illustrations of some of the more unusual items .The publishers will always be pleased to hear of any obvious omissions ,accompanied with illustrations ,for inclusion in future editions .
