主题：无日货，不单反？ -- 白色潜水艇

其实多数是买是看了好玩，实际大部分时间没用过。每次升级换代，这些灵七八碎的总要在广告中反复讲月月讲，似乎是什么了不起的发明。比如DC，对消费者重要的重量，画质清晰度很少讲，对选择相机重要的广角是24mm还是28mm甚或35mm起步，总是写在fine print里，最大光圈在广角远角两端是多少，感光片尺寸，iso表现等，反而在卖相机时不重点突出。

日货这个劣根性在于莱卡的比较是，就很明显了。下面是Ken Rockwell对M9的review，与尼康佳能比较的部分很有意思。

------------- 人机作文的分界线 --------------

徕卡相机一直在20世纪20年代以来，商业。他们从来没有

停止。我们今天几乎是连续多年的结果100

产品开发严重的摄影师。

关于徕卡一切都强烈优化你真正做的，而不是

扩散试图做很多事情，你永远不会做。

举例来说，徕卡M9的第一台相机是我用聪明关闭

自动ISO，只要我的快门转盘转动远离为手动设置。什么

发生在不同的地方在尼康或佳能的情侣十二点击打开

ISO和关闭自动进入手动模式，然后设定快门速度，但一弹

一项关于M9的指尖。 （事实上，自动ISO岿然不动，但仍然在沉睡

徕卡。我用这一招在逆光，其中自动ISO不会试图拉起拍摄

暴露在莱卡，而尼康和佳能系统中经常会曝光过度

背光和任务，我们关闭自动ISO）。

M9的一切都在渗出的情报。例如，第一个镜头是M9的

聪明足以让你把它设置自动ISO根据你的镜头

附后。废话！我已经暗示了尼康年了，和Leica是

第一次听。

对于每一个毫无意义的消费电子产品功能的徕卡M9的免除，像

没有HDMI输出，没有音频，没有视频，没有GPS，没有电子层次，没有幻灯片

与音乐等，徕卡反而充满了深深的东西M9的有用

经验丰富的摄影师。

例如，在回放时，尼康和佳能都可以让你访问到6

每个额外的回放图像信息屏幕。即使有了所有这些废话

显示器，可以告诉我没有佳能的焦距我用。

Leica has been making cameras commercially since the 1920s. They have never

stopped. What we have today is the result of almost 100 years of continuous

product development for serious photographers.

Everything about the Leica is strongly optimized for what you really do, and not

diffused by trying to do a million things you won't ever do.

For instance, the LEICA M9 is the first camera I've used smart enough to turn off

AUTO ISO as soon as I rotate the shutter dial away from A to manual settings. What

takes twelve clicks in a couple of different places on a Nikon or Canon to turn

off AUTO ISO and get into manual mode and then set shutter speed is but one flick

of a fingertip on the M9. (Actually, Auto ISO stays on, but remains dormant in the

LEICA. I use this trick shooting in backlight, where Auto ISO won't try to pull up

exposure in the Leica, while Nikon and Canon systems often try to overexpose in

backlight and mandate that we turn off Auto ISO.)

Everything in the M9 oozes intelligence. For instance, the M9 is the first camera

smart enough to allow you to have it set AUTO ISO based on the lens you've

attached. Duh! I've been suggesting this for years to Nikon, and Leica is the

first one to listen.

For every meaningless consumer electronics feature excused from the LEICA M9, like

no HDMI output, no audio, no video, no GPS, no electronic level, no slide show

with music, etc., Leica has instead imbued the M9 with something deeply useful to

the experienced photographer.

For instance, on playback, Nikon and Canon all give you access to about six

additional playback information screens for each image. Even with all these crap

displays, no Canon can tell me the focal length I used.
