    G1 to LTM adapter

    the prototype should be ready today. i will be trying it out with the CV 15mm, maybe the CV 12mm.

    as soon as I can verify, i will announce availability, but should be early next week

    vivek:
    here is the business end of the CNC lathe used to make the adapter. that tool turret weighs about 1,500 lbs and has over $30k of tooling in it as you see it

    Fabulous Jim
    I'd much rather buy one from you!

    presumably it'll be paypal as usual - any new procedure for ordering?

    Just this guy you know

    Thanks, John.

    That is impressive and more than that needs skill to operate!

    I look forward to your adapter samples.

    Jono, I thought I was the only one getting confused with John Milich's first name!

    His screen name jlm confuses and turns John to Jim, I suppose!

    Re: G1 to LTM adapter

    the adapter is done and works great. tested so far with the CV12 and 15: it will focus at inf, which is the trick. it is cool to finally be able to see focus with that lens. the G1 manual focus system is great.
    tomorrow i will get a 75 somewhere to double check for inf focus and production can start, with shipping late next week

    the adapters will sell for $150 and should work with any LTM base lens;
    e-mail me to order. i'll post a picture tomorrow
    [email protected]

    next will be a M mount to G1 adapter

    John,
    I have a CV 75 LTM at my NY apartment. I'm in SF but if you get stuck for a lens drop me a line and I can have someone go in a grab the lens for you. I also have a 21, 28 and 35 all in LTM.

    John, how much room is available for lenses that have extended rear elements?

    CV is shorthand for Cosina Voigtlander, and LTM = Leica thread mount

    Anything that would protrude through the G1 side of the adapter is generally out of consideration.

    The J12 35/2.8 is a no go for example.

    The G1 to LTM distance would be ~10mm.

    The CV15 is A OK.

    Imagine using the M to M43 adapter with the WATE and MATE. They become zooms!

    made some progress with the M-G1 adapter; was able to focus the 75 cron at inf. now I have to work out the retention springs and lock button
