这也是为啥M3开始后背掀盖了。

用T门，手指帮推一下即可。至于会不会损伤压板弹簧，个人认为可以忽略。

“FED and Zorki, like the Leica, are bottom loaders.  As such, they will only load properly with film which has the long, old-style film leaders.   35mm film used to be available with such long leaders.  New ones have shorter  tongues, which must be cut longer for proper loading.There have been suggestions which call for all sorts of tricks to coax short-leader films into threading into these cameras.  Removing the lens, opening the shutter and inserting cards and fingers into the camera isn’t healthy for the camera.  The pressure plate can tarnish and the springs supporting it can be damaged. THERE IS ONLY ONE CORRECT  WAY TO LOAD THESE CAMERAS, and that is, by loading them as originally instructed.”

唯一的正确方式啊。。。

里面说这个裁片头的方法是徕卡III系列和其他不少种仿徕卡旁轴装卷的唯一正确方法。巴纳克和他的同事们都已经确定了的。。。

There is only one correct way to load film into a FED, Zorki (1,S,2,2s,and 5) LTM Leica,  some Canon RF, Zenit-1,S, 3, and other bottom loading cameras: as it had been instructed!  Barnack and his colleagues at Leitz have long ago determined it to be so.  Any other method would prove to be clumsy, tricky, fail-prone, slow, and awkward.  These could also lead to damage to both camera and damage; using a loading method such as the one show in the picture would also open the camera literally to contaminants.  



Some users think that they have devised a better method than Barnack.  They actually think that they could do shortcuts and use a “better” loading method.  These people suggest inserting a card into the film channel to coax the film into the camera.  This odd method even requires to have the shutter locked open at B so that the film could be „fingered“ into position.   This method is even supposed to do away with the cutting to shape a long-tongued film leader, and enable the modern short leader to be threaded as is into the camera.



Their claim that this awkward method to be simpler, easier, or faster is really a contradiction.  The method is really clumsier.  It requires that the camera be held flat for the duration of the loading.  It requires that a card be inserted slowly and carefully into the film channel.  It needs the lens to be off, exposing the camera to contamination. It requires the shutter to be held open.  It requires the user to poke the camera through its lens mount with his finger. It requires plenty of finger calisthenics to coax the film into position.  It requires the camera’s pressure plate to bear the thickness of both film and card in the very tight film channel and bear on the delicate springs which hold the plate against the camera’s fixed, inflexible back.  For a method which is supposed to be easier and faster, this certainly has too many requirements.



How these people could claim this method to be simpler is a mystery.  All the above steps in place of cutting the film leader properly.  Strange, isn’t it?  How could cutting film be more difficult?   Cutting it to the required shape is the most critical aspect, and this isn’t really too difficult to do.   



Properly loading a bottom-loading camera is a skill which isn’t quickly acquired.  It might even seem impossible for people who have known nothing but auto-loading cameras which run on micromotors.  But it isn’t difficult either.  Practicing with a dead roll can give one the skill needed to load the FED properly.  It is a skill learned through trying and using.   After mastering the skill (it only takes a few rolls to do this),  one could load a bottom-loader  in less than a minute.  In fact,  it’s possible to load a camera in less than 30 secs. I’ve seen people do it.  I’ve done it.

我自己在国外网站找到了一个带图的说明，按照这个里面说的，似乎按照要求裁剪片头是最佳的办法

是，也能装进去，但是比较费劲，好几次才能成功一次，而且最麻烦的是如果不成功的话胶卷会有很多道折痕，齿孔也容易破裂，只好把片头裁掉一段再重新装。。。

IIIc要很顺的装片只能裁，但不必那么夸张，用剪刀从胶片弧形位置往里两三公分重新剪一道弧形就可以了。
其实不裁剪也可以装的，有些窍门，拉出胶片后注意暗盒部位和片轴部位，往里推的时候注意胶片朝机背方向弯曲些余量。避开过片齿就OK了。仔细观察+熟练

相机里面的图是这样的

相机里面的说明那张图也是这么说的 这段细长的片头需要10cm呢

就像这个图里面那样 片头要有很长的一个细条 普通的胶卷片头直接装就很不容易装上

弄了台徕卡IIIc，结果装胶卷很不顺利，总是卡住，装好多次才能成功一次。

后来下载了说明书一看，按照说明书上写的，需要把片头裁出挺长的一个细条，按照这个要求裁片之后，果然装卷容易多了。

是不是必须要这样裁片呢? 为什么会这样呢？我觉得徕卡III系列的过片的那个机构和M3差别不是多大啊，可是M3就不必这样。。。
