How to evaluate the program "Mirror Directory"?

I was a little curious about this program, so I went to see it and looked through some machines I was familiar with. For example, the host of Technika 7 pointed to Linhof Technika 7 and said, "You have seen the biggest and brightest viewfinder … none of them …" I laughed at that time. If you don't know about Linhof 22, I don't think you should be so full. If you can't spread the correct knowledge, you'd better say nothing. Because the magnification of the linkage range finder of this machine is 1:1, it is unparalleled in mass production medium format. I'll give you your own expression back. One set of Technika III 6x9 and one set of Technika 7 are obviously larger, and the brain door with photometry is not a decoration. By the way, if you say that this machine has linkage ranging, people are customarily called Super technika.
