121mm Super Angulon
I have just got a 121mm S.A. mounted to a Plaubel lens panel.
The lens appears to be fitted into some kind of housing which has larger rings for the shutter speeds. However it looks like there is normal Compur shutter mounted into the housing, yet I cannot remove the lens cells and shutter from the housing. Normally one has the shutter,you remove both cells to fit into a lens panel. When you have tightened the locking ring only then you fit the cells of the lens. This thing has a flange which screws tothe lens panel by three screws and the housing screws to that.. |

This thing has a flange which screws tothe lens panel by three screws and the housing screws to that.. I am not familiar with how Plaubel mounts lenses. The use of a flange for mounting shutters is very common. The use of a retaining ring on the back of the lens board has become more common in the last few decades. Some shutters come with combination rings which can be used as retaining rings if mounted on the back of the lens board or as a conventional flange for front mounting. Front mounting is necessary where the lens board is thick. Where a retaining ring is used its common for the shutter to have a pin on the back which fits into a depression in the lens board to prevent the shutter from turning. This is almost universal on press cameras like Speed or Crown Graphics. The retaining ring must be remove from the back in order to remove the shutter. Where a flange is used the shutter will unscrew from the front. However, I've encountered some where the shutter appears to have been cemented to the flange. Very old Speed Graphics, with Compur shutters, are this way, but other cameras are also. Having said that the lens cells should just unscrew from the shutter without removing the shutter from the lens board. I have a couple of Super-Angulons in Compur shutters and the cells of those just unscrew. However, Schneider was fond of using tiny set screws on some lenses so I would examine this lens to see if you can find any. If that fails, and before using force, I would write to Schneider giving them as much information as you can about the lens and ask if there is anything special about it. http://www.schneideroptics.com/ -- --- Richard Knoppow Los Angeles, CA, USA |

What, exactly, does shutter size 0+1 mean?
I have the lens pair for a f8/121mm Super Angulon but no shutter. When I consult Schneider's literature they specify the shutter size as a "0+1". The same is listed for the f8 90mm. S.K. Grimes, Inc. quotes an outrageous fee for installing this lens into the appropriate shutter, so I am left wondering if this 0+1 thing is so arcane that it justifies Grimes' fees or whether I can simply remove the elements from the shutter used for the 90 and replace with the 121mm elements. Does anyone know? |

Does anyone know? My 1968 Schneider catalog shows the 121 SA fitting a 0 shutter. Recently 01 was a 1 size shutter with a 0 size lens thread. An example of this would be the Prontor Professional which came only in 01, 1 and 3 sizes. Another example would be the current Rollei Linear Motor shutter which has a 0 shutter size but only fits into 1 size holes for lensboard mounting. My latest brochure from Schneider showing the 90mm f8SA as being in a 0 shutter for Copal and Compur and in the 01 for Prontor Professional. If you are asking about mounting in a 01 it should be the same price as in a 0 unless your lenses are so old that they are actually 00 thread or unless they do not have standard 0 threads and require a machined adapter. -- To reply no_ HPMarketing Corp. |

The 121mm S.A. is a curiosity in that it appears in a housing or in the
normal form. I have seen four examples on ebay, two housed and two normal. One of the housed examples was also mounted in a Plaubel plate like mine. My interest in dismantling the lens was in case the thing would fit into the bellows of a Pacemaker Graphic. The Primary reason for its acquisition is for my Linhof. |

For the 57 Technika 001051. In Compur Electric 1 the boards were 001128 for 45 and 001129 for 57. -- To reply no_ HPMarketing Corp. |
