Leica photographer rigidity

In addition to what you said, there are three kinds of jade lenses produced by Leica 1965, with a total output of only 9400. The lens numbers of the three jadeite lenses range from 19 1300 1 to 2 125650, and the three jadeite lenses are the first to bend in the 90MM focal length lens.

Please don't compare with Leica's ordinary 90mm4, except for the lens number, the appearance is different. Please note that it needs to be divided, which is suitable for M series digital paraxial and film paraxial fuselage. Sanyu is a Japanese name, Chinese is also a foreign language, and English is only called 3 elements. I suggest going to google to learn English, because I can't take all the Chinese information of Leica seriously, I can only tell you this, and I'm too lazy to popularize science. If you haven't heard of Sanyu, it's not surprising that the total output is 9400, which is relatively unpopular in China, and the corresponding international price is 800- 1000 US dollars.
