Questions about Leicina Super RT1

[hugocodi]

Hi, I have recently been lucky enough to find one of this cameras. I have tried it and everything seems to work. However there are three things that I am not quite sure about and I was hoping that maybe someone here could help me.

The first one is about the exposure. The automatic exposure works fine and I can manage to lock it pressing the arresting button, but when I try to override the exposure using the knob to adjust +1 or -1 stops, nothing seems to happen through the viewfinder. Is that something normal? Is it only going to be noticeable on the film? Or is it just broken?

The second one is about the internal filters, I don't see that much change through the viewfinder when switching from one to another and again I was wondering if this is something that I am going to see only on the film or maybe something might be broken.

Last thing is related with the screw size for mounting the camera on a tripod. It looks like it is a 1/4 inch but it is slightly bigger. I have gone to Samy's, Belair, even Steve's Camera shop who is specialized in Leica... and none of them was able to tell me what size that is. I want to be able to mount the camera on my tripod but it is being very frustrating. I can't find any information online, everything I found says 1/4".

Thank you so much for reading this, I really appreciate any help I can get.

1) Same for me. No change in aperture in the viewfinder with my Leicina Super RT1. In contrast, with the Leicina Super (non RT1), the opening is changed ;

2) The filter changes the aperture ;

3) The screw is standard (1/4 inch). It attaches great. But there may be an internal mobile thread which is gone. The base seems designed for quick system attach (groove).

Thank you so much!

So there are no internal filters then? it just changes the aperture to compensate? Do you see the aperture changing on your viewfinder?

Regarding to the mount base, I actually didn't realize that it might work that way, I will definitely try it.

Thanks again!

Of course, there was an internal filter.
Otherwise the rotation of the wheel 10 would have no effect.



For example:
“Sun” position: 8
“Lamp” position: 11
“Moon” position: 5.6
“Night” position: 8

However, contrary to the Leicina Super, action on the knob 11 has no effect apparent in the viewfinder (without Super 8 cartridge in the camera).

Correction:
With a Super 8 Cartridge in the camera, the diaphragm dial varies from 1 to 2 values​​.

Well, that makes more sense! Thank you so much for the explanation and all the pictures. I am going to test some film really soon and I hope I can share the results here.

Thanks again!
