    Will a Minolta 50mm 1.7 work with AF on a Sony Alpha?
    I see it has 5 contacts, versus the A lenses 8 contacts. But they seems at
    the right place. Maybe the other contacts are for distance info?

  2. The other contacts are for ADI and SSM/xi motorized lenses etc, not all
    lenses with 8 contacts make full use of them. The 50mm AF f1.7 Min works
    fine on the Sony bodies.

    Great. Turns out there are also *non* AF versions of the 50/1.7 and the
    28/2.8. I could have saved the 100 km trip :-((
    I should have known better: 75 euro for both lenses...

  4. Yes, I have both in my cupboard for use with SR/X series bodies. Bad of
    a seller not to inform you they were MC/MD lenses. What a disappointment!

    Yes. The additional contacts are for data that the 50 f/1.7 does not
    supply and/or motorized zoom which the 50 /1.7 does not have.

    The 50 /1.7 is a great little lens:

  6. Nice one! Nicely placed DOF band, the water drops stand out just right,
    subtle colors.

    Does the lens get close enough to do that by itself, or did you use a
    close-up lens or extension tube?

    Thanks.

    This is (drumroll) a crop. No additional lens or tube. I was about
    30cm from the rose. This rose was quite large, about 7cm or so in
    diameter as I remember it.

    The colors are fantastic, I agree. But that was nature.

    I might, if pressed, admit to helping with the water drops. (Truth is
    my girlfriend ordered me to water the garden before supper).

    Cheers,
    Alan

    Over my budget I'm afraid, but very nice pictures...

    I'm a little, if not, totally confused: I'm watching some lenses on Ebay and
    now I read that some Minolta Af lenses WON'T auto focus on Sony? How are you
    suppose to understand which lenses do and which don't? Very frustrating....

    Thanks.

  11. All Minolta AF lenses since 1985 AF on Sony except the 1-3X special
    macro zoom. Even the ones which don't work fully with SSS - like the
    original macro 100mm and 50mm that I have - still AF fully.

    Some early Sigma AF Minolta mount lenses don't AF on Sony but these also
    do not AF on any Minolta after 1989!

    So which do not have SSS support?
    Isn't there a list of lenses that explains it?
    Thanks!

  14. There were mentions back in the days of the 7D launch. The only lenses
    which they said would not be fully supported for AS/SSS were the macro
    lenses, and I guess the reason is that at 1:1 the focal length no longer
    computes relative to the effect of shake.

    Every zoom and prime made, other than macro lenses, works. That includes
    the 500mm AF mirror.

    Minolta lenses compatible with the Sony alpha are "A-mount". With a few
    exceptions they are all AF lenses.

    One manual focus exception is the Minolta 135mm /2.8 [T4.5] STF (Smooth
    Trans Focus) lens, a fantastic lens for portraits and absolute creamy
    BG's. 100% compliant for the Sony Alphas. (There is a Sony "SAL"
    version of this lens as well).

    As David pointed out the 1x-3x macro is not 100% compliant with the
    Sony's. The only drawback as far as I know is that the anti-shake won't
    work, but it's a lens you'll have on a 'pod most of the time anyway.

    The "before A-mount" lenses were MD, RC (and RF). Rokkor is a common
    Minolta brand that that was an MD mount. Don't get these for your Sony:
