    Used the 14-140mm with a G1 so far, and was always satisfied.

    Changed now to a G3, and I'm disappointed about the sharpness result's.
    8 out if 10 pictures are very soft and it does not matter which focal lenght.
    When I shoot with the 100-300mm, I get good results.

    Some one made same experience ?

    Thanks for any feedback

    Do you have some samples?

    Which mode/settings are you using on the G3? You could probably stand to turn down the NR quite a bit.

    Distance is around 30meters
    Camera laying fix on the table (not freehand)
    time = 1/125 / F = 5.7 / focal = 135mm
    focus on the face
    the crop is 1:1 out of the original size

    Maybe the focus's missing? The window behind the man looks good, or so it appears, not sure.

    OIS on 14-140 set to on? If sitting on table, could OIS introduce some vibration?

    I think it's due to missing focus, apparently that G3 is not driving the AF motor precisely, both camera and lens damage can cause that, if you could try the G1+14140 again or G3 with other lenses it'll be easy to know.

    IOS was on

    Figured out, when switched to "point-focus" mode instead of "field-focus"
    the results are better.

    Will do some comparison shot's also with the G1;

    Thanks so far

    Does that mean G1's field focus does better than G3's? I'm having some blur images with field focus on GF3 sometimes, it's not smart enough

    I shot more or less with "field-focus" mode only so far; with G1 as G3

    Just experimented a little bit at a weekend trip, and figured
    out afterwards, that these few pictures shot in point mode seem to have
    a correct focus.

    As posted at the beginning, I do not have the same with the 100-300 glas.

    Did some tests shots today, and I'm helpless;
    Shot with focal lenght 120mm, freehand, with OIS, and f5.7
    Compared the 14-140 and the 100-300, both @120mm
    Same camera settings with the G3

    The 100-300 is much sharper than the 14-140.

    Either my 14-140 is of poor quality or this lens is just much softer than I expect
    Your comments are apreciated

    Both are 1:1 crop of the original size:

    To eliminate the possibility of shake try them on a tripod with OIS off. Try also using manual focus, again on tripod. Maybe the 14-140 is damaged or OIS not working ? There seems to be more difference than you'd expect in those bike shots for sure.
