New patent from Olympus for a FT to MFT adapter

Few months ago Olympus did confirm their commitment to the Four Thirds format. The company recently filed a patent (2012-230323) in Japan for a Four Thirds to Micro Four Thirds mount lens adapter with built-in autofocus and image stabilization. This is not a surprise, since every manufacturer that has a mirrorless and DSLR cameras today also offers compatible lens adapters.

  • Adapter with optical elements?


    Probably a better option would be to use 4/3 lenses on NEX and just crop them. At least you won’t loose the image quality.

    And as for the image stabilization, no idea why Olny would need it when their PENs got quite impressive IBIS.

    If their commitment to 4/3 is going to look like that then well… no wonder everyone already think this whole system died to give a birth of m4/3.

    If it’s to adapt a 4/3 lens to a micro 4/3 camera, this adapter seems oddly unnecessary, as such an adapter already exists without lens elements. This must be the reverse, a m43 lens to 4/3 camera adapter (for which lens elements would be required to alter the focal distance) .

    I hope someday they make the 0.5x m43 to OM lens mount adapter which alters the focal length of OM glass so that 50mm becomes a 25mm lens, which is standard for m43. They patented it.

      Never mind, this adapter apparently adds optical image stabilization for 4/3 glass and adds AF sensors and an autofocus mechanism for micro four thirds cameras to use PDAF. This seems to be an enormously complicated way to do what could have been done rather simply with in-body stabilization (which they have) and PDAF sensors on the image sensor itself, or with a simple pellicle in the adapter, as the lens already contains the movable lens elements and motors needed. In every way, this adapter seems redundant- and that makes me wonder if the patent describes the device accurately, or just discusses the patentable innovations of such a device.
