    It seems that there are very few auto-focus lenses available outside of Olympus and Panasonic. Certainly I'm aware that Tamron makes a couple but given the open nature of m/43 I feel like there could be more. Why is nothing from Rokinon AF? Do they just not make AF lenses?

    Samyang (aka Rokinon, bower, etc) does not make AF lenses.

    As far as I know, currently the only third party AF lenses are the Tamron super zoom 14-150mm, Sigma 19mm, 30mm, 60mm, Kodak 12-45 and 42.5-160mm.

    m43 is not an open standard. The difference is that unlike other proprietary systems, anyone can join and get the specs instead of reverse engineering.

    I'm pretty sure that every manufacturer making m43 lenses, except Samyang, have bought in and are members of the group.

    The MF lenses are all mechanical and are nothing more than a body cap to the camera. To implement AF the lens has to have a full electronic interface for AF motor and aperture control with the camera, because all control of the focus and aperture is done by the body. It makes the lens a lot more expensive.

    The 3 Sigma primes are good, 19, 30, 60mm all F2.8. Sharp and fast focusing. Hopefully Sigma will make more M43 lenses though as these are all APS-C lenses with a M43 mount and larger than they need to be.

    Agreed. Just buy the 60mm last week and try it and feel very surprise with it peformances.

    The Sigma 60mm is really quite small - it's a small fraction of the size and weight of the 75mm f1.8, and barely larger than the 45mm f1.8. The Sigma 60mm is also an optically superb lens, and very versatile. You can also screw front achromat diopters onto it and get very nice macro performance with AF support. The fact that it was originally designed for the APS-C format is one reason that the performance at the edge of the 4/3 frame is so good with this lens - very nearly as sharp as at the center.

    Wow.

    IIRC there has been some very nice work done with "nothing more than a body cap:" Mathew Brady, Eugene Smith, Dorothea Lange, Richard Avedon, Yousuf Karsh, Ansel Adams and others come to mind.

    Try this one: "Auto-focus and auto-exposure are expensive and fragile crutches for people who lack basic photographic skills and knowledge.":biggrin:

    I don't think the "body cap" comment was intended to be the put-down you interpreted it as - it is simply a fact that the electronics of the camera's lens mount don't recognize manual lenses - and the camera responds as though there were a body cap on it. In fact, Olympus makes a couple of inexpensive wide angle small aperture fisheye lenses that DO double as body caps, but some creative folks have taken some great photos with these body cap lenses.

    Well ... there you have it.

    I think Tamron, Sigma and Kodak are enough for now,
    considering the sheer number of excellent AF lenses existing so far.
    I can recommend the Sigma 30mm = very good in every way.

    Sigma lenses are not more expensive. At all.

    Where are Kodak branded lenses sold? Never seen one in the USA.

    They're sold in the China domestic market. A user here has posted a thread or two about them.
    He said focus is quite slow.
