    A7 manual lenses stop down metering ??

    Hi.
    Is this correct:
    1) When you use a manual focus F mount lens, Nikon or Zeiss or ... with the Novoflex adapter, you must meter stopped down to the shooting aperture?
    You can turn the ring on the adapter to open up the lens for focusing but have to stop back down for metering and shooting - kind of like the old time pre-set lenses of the 1960"s?
    2) Using a M mount lens, its meter and shoot at the working aperture only, unless you want to work the f-stop ring back and forth a lot?
    thanks,
    Robert

    1) Correct - but there's a lot to be said for focusing at working aperture, because you avoid any focus-shift issues by doing so.
    2) Same as above - this basically applies to all lenses whose aperture can't be controlled by the camera body.

    Yes and yes. Same old stuff. Nothing new.

    for 3 use the wheel/dial to correct the exposure compensation (one has to "menu dive" in the M digitals for this!) instead of changing aperture.
