Hi,
A friend has sent me a lens assembly from an old SEM camera, which I'm planning to use in a custom panoramic I'm building. However, I'm not sure how complete the assembly I have is. I'm wondering if anyone knows much about these lenses? I _think_ it's from a TLR camera, but I couldn't be sure; if it is then I have only the taking lens.
The information around the lens barrel is as follows:
FLOR 1:3.5 f=75 SOM BERTHIOT P43400
The aperture control seems to work, as does the shutter.
If it helps I can provide an image of the various pieces I have.
Thanks in advance for any advice!

This obviously is the taking lens from the french Semflex TLR. I have one of these with the same lens designator. The shutter is made by SEM as well and usually has the OREC designator, it comes in two flavours, one with 1/10 to 1/400 and one with 1 sec to 1/400. The viewing lenses of the Semflex had the same design but f/2.8.
Berthiot lenses have a good reputation. The Flor lens is a 4-element Tessar type design. Some french 6x9 folders have a Berthiot Special lens (usually f/4.5 or f/3.5 and 105mm) which perform quite well, too.
The lens you have will cover the 6x6 format, I am not sure how you are going to use it on a panoramic camera?
If you do not have any idea how to use it, maybe I would buy it - the lens and the shutter on my Semflex do not work too well since they were stored in a humid place for years - I could save it just before it was totally corroded. |

Hi Winfried,
Thanks for the lens information. The one I have has a shutter which does 1/10 to 1/400 I believe.
The panoramic camera is an idea based on a Dirk Fletcher design, using the body of a Nimslo 3D camera and an appropriate lens. The Nimslo exposes a 35mm double-width negative area, so by using a medium format lens you can get a good panoramic result.
Having looked at a few sites, it seems that my lens is missing at least some parts; the aperture and speed indicator rings and the 'figure-8' lens mount, among others. However I'm glad to hear the lenses are well-regarded. I should be able to figture out a way to mount the lens and work out the aperture and speed settings (hopefully!).
Best regards,

I see... even if you would have decided NOT to use this lens I hardly will be able to use it on my Semflex due to missing parts.
However, Dirk Fletcher is not the first one having the idea to convert a Nimslo body to a panoramic camera.
See
http://www.panoramakameras.de/24x73.htm
for one of the panoramic designs of Mr Graumann. He also uses Mamiya rollfilm backs (for 120 format panoramic cameras), FED-Stereo bodies and a 35mm repro cartridge with integrated transport mechanism made by the czech company Meopta. |
