    Know anything about Argus Wide Video converters?

    I inherited a Argus wide (must be video) converter 1:1.8 6.5~26mm. I'm wondering about the "X" factor. I'm thinking it's a .75x multiplier, but I don't know and I can't find anything thru Google. Any ideas?

    Picture! picture!
    I think the Argus brand predated video by a few decades

    It is probably to extent the zoom range on a super 8 or regular 8 camera.
    I use a modern Tokina converter on my Bolex to get to 4mm-18mm range (from 8mm-36mm)

    Here's a picture. The converter has 49mm female threads on the back and is made in Japan. 6 glass surfaces from what I see by way of reflections.

    argus-cossina wasn't the only one with 49mm screw mounts for 35mm SLRs there were various other models by other brands, Sears etc; it converts a medium lens down to a wide angle. in which case you divide by the given ratio on the lens: 1:1.8. Thus on your 50mm camera lens if your focus rings says 20' its really 11' with the converter on (20/11=~1.8) or on the opposite end 4/1.8=2.222 etc; which is rounded up to 2.3'.
    initially, i was thrown off by the "video" part.

    I to was confused as I could not find anything as to it's use whether as a camera OR video converter.

    The inside cap of the converter has a chart which gives the focus distance as explained by you. I'm confused tho as to how that translates to field of view.

    you'll get a more macro fov. it nearly doubles your field of view but changes your dof as well.

    Ok thanks for posting the picture. Looks like it is to go on a normal lens for a 35mm camera as a wide angle conversion. The fixed lens 35mm rangefinders (Konica, Yashica etc) usually had these as add-ons. The one you have may work on other formats also*.
    If you don't have a camera with a 49mm thread, can't you just hold it up to the front of the lens and see what it does?

    (*That one I'm using on the Bolex also has a 49mm thread.)
