I believe the in/visible dot concept system was first used by Kern Switar on their 16mm cine lenses back in the 1930's / '40s(?) but here's a link which has a bit more detail about the Kern Macro-Switar 50mm f1.8 which was produced (starting in the late '50s) for the very high quality range of Alpa 35mm cameras: https://aboutphotography-tomgrill.blogspot.com/2013/07/the-50mm-kern-macro-switar-lens.html Having tried-out a couple of Typoch's lenses in the past (and an original modified-for-Leica Kern Switar more recently) I agree that it really is quite a lovely thing to watch happening in the flesh but (IMO) not nearly as 'intuitive to assess' as good-old lens-barrel-scribed D-o-F lines...

GFW2-SCUSA Posted June 24 Share #6  Posted June 24 I wonder if those tiny holes would allow moisture from a misty day get into the lens. I know they are not meant to be weather sealed, but don't we all take our cameras out in foggy, damp or even light rain? I remember such a thing on an Alpa camera that one of my parents had many, many moons ago.  1 Link to post Share on other sites More sharing options...

I remember such a thing on an Alpa camera that one of my parents had many, many moons ago.  There has been quite a bit of discussion about this in the numerous threads on Typoch lenses and the consensus seems to be that they had thought this issue through (as might be hoped!) and no problems - as far as I am aware - have been reported. Having said that I should emphasise that I haven't given the entire www a deep-trawl regarding this matter so take my comments in the spirit in which they have been offered!

Even as I was typing 'Kern Switar' I had the inkling that I was mistaken hence my slightly shame-face ambiguity in post #3. Cheers! Philip. Link to post Share on other sites More sharing options...

Yah, in the mid-20th-century, there were quite a few odd-ball "analog-automated" indicator systems created. In addition to the Kern DoF dots. Hasselblad's C lenses (1957-1982) had red moving blades connected to the aperture ring - stop down with the aperture ring, and the blades spread apart ||<      |      >||  to quickly/intuitively show the wider DoF range, without having to read the aperture numbers twice. Or so it was argued. See first image here: https://emulsive.org/reviews/camera-reviews/hasselblad-camera-reviews/the-hasselblad-v-system-master-guide-c-and-c-t-star-lenses Not limited to photo gear. In a similar vein, c. 1960 Mercedes cars had vertical speedometers, that were a rotating tube behind a thin slit in the instrument. Car sped up, tube rotated, a painted wedge wrapping the tube "climbed up" the slit, and changed color, to indicate higher speed. My godmother drove one of those.  Not sure what the influence was for such ideas. Simulating the "space-age" indicators** of the early jet fighters or spacecraft? Copying the "look" of early digital-computer readouts? Trying to be "different from and fancier" than the increasing camera or auto competition from Asia? Just a general desire to look "cool and modern?" **See: The Apollo 13 movie, with "vintage" indicators recreated for that spacecraft https://www.nasa.gov/wp-content/uploads/static/history/afj/ap11fj/pics/gpi.jpg - and also pre-LED numerical-display "Nixie tubes." https://en.wikipedia.org/wiki/Nixie_tube Anyway, back to the new Thypock 21 f/1.4.........
