    What functionality is available re focus & exposure when some of this wonderful, old glass is mounted on a GH3?

    There will be no communication with the camera body. Set the camera to Manual mode - set the shutter speed on the camera body, adjust focus and aperture on the lens. You can also use Aperture priority mode - set the aperture and focus on the lens and the camera will select the shutter speed. LTM lenses work well with the exception of wide angles that may cause smearing in the corners of the image. I had the best results with 50mm and 75mm lenses.

    ... so, if I understand this, "A"perture priority mode allows me to use the in-camera light meter, but in "M"anual and "S"hutter priority, I'd have to use a hand held meter.

    On Panny (and I'd bet Oly has it has well) in M mode what used to be the exposure compensation becomes an exposure meter. So no handheld meter is necessary.

    You can also use the in-camera metering ( displays +/- in f/stops) in Manual mode. Shutter priority will not work because the camera cannot control the lens aperture. Be sure to set "Shoot w/o lens" to ON in the Custom menu.

    Ok,, I see that the "A" mode works with the camera selecting a shutter speed, but I don't see anything happening in "M" mode while I adjust the shutter speed and/or aperture. Where should I be looking?
