Switar for H8

The lenses you mention were specifically designed for the H-8 Reflex and they exist in one form only, whether people forget to write RX or Macro or something. The wide-angle Switar wouldn’t need to have a macro facility because it takes quite a short extension for shorter conjugates with that short focal length. The 5,5 mm can be focused down to 11 cm and if you want to go closer with it, a shim washer or an extension ring will take you there. 11 cm can already be treated as macro.
The correct designations are
Kern-Paillard Macro Switar 12,5 mm, f/1.3 RX;
Kern-Paillard Macro Switar 36 mm, f/1.4 RX;
Kern-Paillard Switar 5,5 mm, f/1.6 RX.
The 12,5 is a wonderful lens, it derived from the 50 mm Macro Switar for the Alpa 35-mm. film SLR camera.

Thank you, Simon.

You mean the aluminum rings, there are no grey parts. Obviously, the engravings got changed over time but from the red lacquer together with the extension you can tell it has the macro function. Please, don’t ask me when the changes occurred.
For the Pan-Cinor, it cannot hold up against the primes, especially in the shorter focal range. The thing is that we need the very best projection lenses, if we want to compare images from different taking objectives, and fine-grain films. I have Kodachrome II and Kodachrome 25 exposed behind these lenses, incomparable. There was a time when the Eastman-Kodak Company mastered a so-called cascade or cataract coating which resulted in the thinnest layers ever given to films. KM 25 has two separate layers for each primary colour, that is six distinct gelatine layers for RGB alone, plus a number of filter, subbing, and top coat layers. Together the package was not thicker than that of an ordinary black and white film. Kodachrome slides 24 × 36 and bigger exhibit a unique image quality primarily due to the thin layers. In short, try black and white positive (print) film to evaluate a lens’ performance. It’s got only one layer, a bit thicker for the maximum density of log 3 or so (enough silver stacked in space) but it is the most honest answer to the question.

Yes, aluminium, sorry for my bad English, Simon.

There are simply longer threads and the rear barrel has a red band painted on. The whole lens moves.

So, for enter the macro "mode" function just pull the lens forward and the red band painted comes out? And for return in normal mode have to press in the opposite direction and the red band disappears?

I found an image that shows that even the 36mm with the only written "Switar" has the red band.
Sorry, Simon, without the lens in hand, I did not understand how to insert the macro function (from without red band to with red band).
P.S. How do I post pictures? I've seen the previous ones have been removed. Is not the external link good? I can'tfind the regulation.

Ok, I bought the three lenses at a good price, waiting to test them.
P.S. The external link now are Ok.

I think with Macro Switars the lens focus scale rotates twice, to extend the lens further out. During the second rotation the red section is revealed so you know you're in macro mode. I think that's right, been a while since I had my hands on a Macro Switar.

Thank you, Dom, I try when I get the lenses and and I update here.
