    Any experiens with this lens? good? bad? what?

    Does anybody have any experience with this lens and shutter? It is a Steinheil Munchen Doppelanastigmat Unofokat 1:4.5 f=16.5cm on a Compur shutter. I had it CLA'd and have not had a chance to shoot with it due to the fact that I do not have a retainer ring and cannot find one.

    No experience, but the 165mm focal length is interesting and looks to be a nice small lens. Have fun with it!

    What size of retaining ring or flange do you need?

    Hi Jon,

    I am not sure, but I will take some measurements and let you know.

    thanks

    Steinheil was a highly esteemed manufacturer from Munich (inventor of the rapid aplanat/rectilinear design, 1864). I have an Unofokal 4.5/150mm from 1925 which a previous owner found worthy to get it coated. It is a great vintage lens in a great shutter. The Unofocal is a dialyte design (4 elements in 4 groups) comparable to a modern Apo-Ronar. It is super sharp with high resolution and medium coverage. It also has beautiful bokeh in my opinion. I guess I don't have to say much about how great the Compur shutters are. Yours was modified by adding a flash sync. It should be a Compur 2 and finding a retaining ring is nearly impossible. For testing you can make a makeshift retainer from thick, sturdy cardboard (like a 3mm mat board). But in the end you may want to get one machined from metal.

    Here are two examples that I shot with my 4.5/150



    @ f/8



    @ f/5.6

    Hi, f/8 is just great. May I go OT and ask how you lighted it? Thanks

    A ring is not necessary for a lens that light. Put it through the hole on the board and add a little hot glue around the back.

    I might have an extra retaining ring good for your Compur.

    I recently got a flange from SK Grimes for a "No. 2" dial set Compur for $35.00. If you go to their website you will find they offer as stock items flanges for 4 different mount sizes of this shutter. Also some of the listed sizes are quite close together so they might want to have the shutter in order to make sure of the fit. It looks like they only have flanges (the thing that fastens to the front of the lens board with screws) but not retaining rings (the thing that you screw on the back of the shutter after putting it through the hole in the lens board) for these particular shutters.

    David, you are right about this. I own two "No. 2" Compurs, one has a flange diameter of 43.8 mm, the other of roughly 56 mm. The dimensions of the old dial set Compurs were all over the place and little standardized. This drove me so crazy that I even started a data base.
