So basically the long exposures are like control of the bulb exposure. Which is cool! So if you want to shoot longer than 4" can you do that too?
So there is no way to attach Xenotar to regular Makiflex at all to focus to infinity?
Hi Milos,
1) Yes you can time any length of exposure by using the "B" Hours and Hours if you want
2) Yes, it can be done to work with both cameras. But I have not completely gotten around to it yet

See picture of my 150mm F2.8 Xenotar below. It is mounted on a Plaubel Peco Jr recessed lens board,
that I had around. It fits the Makiflex Standard, but not the Makiflex (because the recessed cone is too
big to fit into the front of the Makiflex. The interior recess is smaller on the Makiflex, because of the automatic
cables inside the body. If I got a smaller lens cone to recess the lens (like a Durst IXOTUB) it would fit both
cameras. This will involve an intensive amount of metal cutting.
Second problem: When focused at infinity, the Xenotar rear cell strikes the mirror inside the camera body, when you go to fire the shutter. Solution: Remove a lot of heavy brass material from the rear of the Xenotar cell



(see the picture, I have done it!) and you can fire the mirror with the Xenotar on both of the Makiflexes. Actually Plaubel had an Automatic version of this lens and that is exactly what they did at the factory! A nearby camera dealer has this very lens, and lent it to me for a weekend, to take pictures and make measurements
Whew!!

A lot of engineering and very heavy metalcutting. But it can be made to fit both cameras.
I just have not gotten around to building the final recessed board that will fit both cameras. Stay tuned
