    A few "Ziggy" notes:

    While these two bodies have very similar names, a7 and a7R, they are very different internally. From the increased pixel density of the a7R to the (potentially) better AF section of the a7, they will have different shooting properties for both still and video. Why Sony chose this naming structure they do not say, but this will certainly present some marketing challenges to prevent confusion in the marketplace.

    These new bodies appear to use a short flange/focus distance, so the previous Sony/Minolta FF lenses will need to be adapted to fit these new body styles. Accordingly, Sony has announced 5 - new lenses specific to these new bodies. Adapters for previous FF lenses are the LA-EA3 and LA-EA4, with the latter providing "... the ultra-fast focusing and shooting capabilities of Sony’s innovative Translucent Mirror Technology."

    The a7 and a7R do NOT come with external battery chargers. They are designed to charge batteries in the body.

    These new models also seem to mark the end of the Sony "NEX" model line (according to DPReview).

    Apparently they can fit any lens (Canon, Nikon,etc.) which could be a smart move

    Unfortunately, I am not aware of any powered AF adapters for other manufacturer's lenses, and very few adapters with powered and automatic aperture capabilities for Canon "EOS" and Nikon "G" series lenses.

    For older manual-everything lenses, you are correct; this could be a potential benefit for certain genres of photography and video production.

    These will be a dream for landscape and tripod work and using legacy lenses. However for any other use, if I'm buying a camera that has to be carried in a bag, I will take one with an optical viewfinder every time.

    Too bad that 35mm lens isn't f/2.0.

    An "accurate" reproduction of a scene and a good photograph are often two different things.

    I'm biting... preordered the A7r along with the 35mm and the 24-70 f/4 lens. mwink.gif

    The DPReview full review of the Sony Alpha 7 is up:

    While the reviewers were pretty impressed with many aspects of the camera, AF speed in low light and JPG rendering were troublesome points. Also relatively short battery performance and poor auto-ISO algorithms may challenge some shooting styles.

    Still, for an inexpensive, FF, mirrorless body, with competent RAW and a smaller form factor, this could be a solution for some folks. They were also impressed with video performance.

    I don't know about a "powered AF" adapter but adapters are being used with Canon EOS lens, albeit dealing with the slow AF
