Questions about Leicina Super RT1
Posted 27 June 2011 - 01:09 PM
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

The AutoExposure bias knob should show a change in the aperture display in the viewfinder when changing it to another position. Keep in mind the change is in 1/3 Stop increments, so it will require considerable rotation of the knob in either the Plus (Over-exposure) or Minus (Under-Exposure) direction to the aperture scale move. If yours does not move, then either the exposure is locked, the power is off, there isn't a cartridge in the camera (required in order for the camera to be operated....so it helps to have a junk scrap cartridge available to play with the camera's settings in a 'dry run' mode), the batteries are weak or a poor connection from the battery chamber to the camera body (make sure the contacts on both camera body and battery chamber metal fingers are clean), or something is wrong with the autoexposure mode.
The Builtin Daylight Conversion Filter is moved in and out of position via the 4 position knob on the right side of the camera body. The Filter change can be seen if you look down the front of the lens, with the zoom in about the halfway position and either using a small flashlight or under a light source....you'll see the filter move in and out of position. There isn't any viewfinder indication, which would've been nice to have. But then, many Super 8 cameras don't indicate the Filter Position in the viewfinder display.
And lastly, yes....that troublesome Tripod Socket. The LEICINAs are made in Germany and are threaded from the factory with the European Tripod Thread Standard which is larger that our quarter inch "Whitworth" thread. Usually they were fitted with a small screwin adapter which reduces the size to our quarter-inch one, but these can unscrew by repeated tripod use, if it's not seated in tightly enough. BOLEX tripod socket adapters will fit the LEICINA (and all other still and movie cameras that have the european sizing). You can find these for BOLEX on eBay and from various vendors. So, once you get that adapter, you'll be fine. They are usually under $10 USA, but pricing varies depending where you buy them. That nice low center of gravity on these LEICINAs really helps make for rock steady images (and the unique film gate design also contributes).
Hope you sort this all out soon and get to use your new camera!

With a Super 8 Cartridge in the camera, the diaphragm dial varies from 1 to 2 values.
Of course, there was an internal filter.
Otherwise the rotation of the wheel 10 would have no effect.
“Sun” position: 8
“Lamp” position: 11
“Moon” position: 5.6
“Night” position: 8
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).

It is definitely quite different this camera. I have to say I was doing my tests without a cartridge, I can't believe I didn't think about that... now I know what to do. The battery compartment was a little bit dirty when I got it but I cleaned it and now everything seems ok so I hope it will be fine when I test the film. I really can't wait! I intentionally bought a tungsten film to test the internal filter although I will try the internal and an external one I have as well.
Thanks Martin for the tips on the tripod thread! I was really about to give up on this one. The guy at Steve Camera Shop wanted to charge me $100 for an adapter...
Really thank you guys for all the help, I am very excited to try my Leicina and hopefully I will be able to show the results soon.

1/4" 20 threads per inch and 3/8" 16 were both common on pre-WWII German cameras and British cameras. The 3/8 thread was more common on larger cameras. Apparently both sizes are BSW - British Standard Whitworth, and are accepted as the international standards for tripod mounts.
So I guess any of this adapters will work:

So I built my own. Two pieces or red oak glued together, some washers and a screw. It works perfectly and now I can attach either 1/4 or 3/8 mounts to it.
I included some links with pictures:

I also tried some film that I bought from Pro8mm, and the camera did not recognize any of them. It was frustrating... well I guess I will find out what is going on when I develop it. I will post more updates when I have it.
Thanks for reading.

Pro8 cartridges do not have notches?

Any recommendations for Leicina service preferably in the USA? Although I am open to send it to Europe.
Thank you so much

The knob is not on single frame, as a matter of fact I tried the three positions and nothing happens. It feels like is trying because I hear a slight movement but it is like something is stuck. Batteries are new and fine, I already removed them and placed them back. It happened while messing around with the camera. I was trying to remove some dirt, and I unscrewed the main screw on the axis that rotates the film. After putting it back to place it wasn't working anymore. I feel so horrible but at the same time I don't understand because it was just a screw. I am scared to keep touching it, and that is why I was thinking on taking it to a specialized camera shop. Is that bad that I touched that screw? I hope I didn't brake the motor.
