    G1 Wide Angle converter

    How difficult would it be for someone like a CV to develop a negative diopter converter as part of a LTM or M adapter that would restore the WA the sensor eliminates. A teleconverter in reverse. It would be "standardized" for certain focal lengths i.e. a 15-21mm or a 24-35mm and only 1 camera thus not trying to accomplish too much? I understand it would put more glass in the path - but at what price?

    The kind you are looking for if it were to preserve the aperture (light transmission) and the image quality is possible but they would cost more than the new 50/0.95 Noctilux.

    Such converters use precision relay optics. There are no cheaper ways to do it other than a front mounted afocal converter.

    I have been experimenting with one for the kit zoom. A 0.7X converter appears to be OK. I have to check it further to say more on it.

    Hopefully not too much barrel distortion...a 0.7x would make the kit lens 20mm/3.5, not bad at all.
