This is such an excellent review of this camera. You are the only person I've ever encountered who knows how to distinguish between different models. Thank you so much for making this video.
Thank you for your comments. Actually I had a plan to add English captions, but I did not do it so far. I just added the English caption to this video clip as a first step. I would like to add them to the other camera-introduction clips. I hope more people enjoy them!

Thank you for the clear and enjoyable video. I was especially interested to see the difference between the viewfinders of the original Automat and the Automat II. About the narrow frame spacing: The Automat measured the amount of film for each exposure by how far the spool was turned. As more film built up on the spool, its diameter would become larger, so each turn would advance more film. To compensate for this, the Automat's film counting wheel had stopping notches that were “differentially spaced” - wider at first, then closer and closer together. This compensated for the increasing diameter of film on the spool. The problem today is that many modern 120 films are much thinner than films of the 1950s. Because of this, the spool diameter does not build up as quickly and the spacing of the notches does not advance the film far enough. Other folding cameras with the same type of counter, such as the Zeiss Super Ikonta B, also have this problem with thinner modern films. On the other hand, roll film cameras that used a film measuring wheel (such as the Rolleiflex, Minolta Autocord, and Yashicamat) do not have this problem because the measuring wheel rolls along the film and measures the linear distance that the film travels, stopping it after the correct amount has been advanced. These are not affected by the differences between thin and thick films. However, that system is more complicated and more liable to get out of order than the simple, reliable film measuring system on the Mamiya 6.
Thank you for your informative comment. I totally agree with you. Narrow spacing problem is very common to most medium format cameras in 1950s such as Konica Pearl III. One major motivation to change the film advancing mechanism was the appearance of 220 film because the diameter of the partially wound 220 film is thinner than 120. (Of course I know some cameras before the debut of 220 film already have measuring wheel; for example, Kodak Medalist). Other aspect to restrict the modern film advancing system is the existence of the bellows. In most cases, the bellow exactly covers the film aperture, and it is difficult to place the measuring wheel around the aperture. so the modern mechanism also affects to the size of the camera IMO. Fortunately my three instances of Mamiya-6 automat / II have no overlapping problem, and the spacing is narrow but very stable, owing to the very precise manufacturing by Mamiya. Thank you for watching.
Very informative video, I only understand a little bit Japanese but thanks to the English subtitle it's totally clear. Greetings from China and thanks to your comprehensive introduction.
Thank you so much for this review! This is the only one that mentions about having to manually set the shutter if advancing the film with the lens closed, I just received my Automat II and was beginning to think the shutter mechanism was failing.

I am very happy to hear so!
Thnk you so much for the review... I think i will buy this camear .. it looks great and very well made!
Cheers
Thank You I don't understand Japanese but I unstertood your video perfectly. That is a sign of a real teacher in my book.

Great video Shinsaku san, those cameras look in mint condition, I hope I can find one to use one day.
Thank you for the informative Mamiya six video and subtitles. Very helpful.

Thank you, this video helping much to use my Mamiya 6 automat.
Greetings from the Netherlands.
Thank you, it is my great pleasure.
Thank you for the subtitles! Very informative.
Thank you!!
thank you very good and well explained

Do you find a great difference between the Zuiko vs Sekor lenses?
No, my favorite Zuiko is really excellent lens but I can not find evident difference from Sekor. Both excellent.
