    Hi Seth. I think this was brought up before but cant recall. On the mount - not 100% sure but due to the chip size you'll most likely cop a whack of vignetting.

      Yes there are B4 mounts made already; I even have one but haven't tried it out. I think the mount I have is B4->Canon FD, and then you'd use an FD->M43 adapter, but if you root around on ebay you might even find a B4->m43 adapter.

      As Noel said, it's of limited usefulness because B4 lenses are designed to cover a 2/3" chip, which is less than 1/4 the size of the AF100's chip. So you'll have to zoom in quite a bit, and use an optical doubler, in order to get full coverage without vignetting. And of course there's no way to power the zoom or auto-iris.

      So yes it can be done. Whether it's a practical solution, well, that's another question.

        Here is short answer.
        Any B4 zoom 2/3" lens with 2x extender works fine on m4/3 bodies.
        Without extender you'll get heavy vingetting.
        In GH1 sections you can find large thread about this.
        Converters are very rare and costly.

        Sometimes I don't get Panasonic. Why they do not produce cheap ($30) converters to B4 and few other ENG lenses mounts?

          Is there a crop video mode? ..... it would make so much sense if they could have a 2/3" crop mode for us to use PL 16mm lenses and such.

          (assuming the sensor is larger than 1920x1080)
