  • Manual focus with FBW lenses

    I use manual focus regularly in lanfscape and macro work.
    I hate how slowly Focus by wire lenses operate and I wish Oly would provide some way of controlling the focus speed specifically speeding it up to be more like mechanical focus.
    If my 35mm f3.5 would focus better manually I would use it much more than I do.

    I received an Olympus M. Zuiko 14-42mm f/3.5-5.6 EZ ED MSC Lens today and was very surprised at the speed and feel of the MF it was great.

    So why cant the other lenses focus like this?

    I use AF+M so that the AF gets it to where it needs to be and then MF to fine tune to where I want the focal plain to be.

      The manual focus action on the SWD lenses is quite nice. The focus by wire on the 7-14 is so bad I leave it on AF 95% of the time.
      It's the image that's important, not the tools used to make it.

        I find that the MF of the 4/3 35mm macro on the EM1 is rather jerky. When focussing, you can see the focus change in jumps. Given the thin DoF in macro, this is not ideal.

        The SWD lenses should give better feel in MF because the focus ring is permanently mechanically coupled and so drives the focus even when the lens is not on the camera. That is the advantage of ring-motor type AF.

          Thats is pretty much why my macro lens is the Sigma 105 as I acnt be bothered with the 35 mm being slow in MF and AF for macro is no use at all IMO.

          Why cant Oly do a firmware upgrade where you tune the focus speed on the FBW lenses making the usable in MF.
