    Sigma / Pentax K-1 issues - warnings

    Warning: Sigma Japan has posted a product advisory warning customers that when select Sigma lenses are attached to the Pentax K-1, a minor scratch to the camera's lens mount may be inflicted

    Sigma: Phenomenon

    When some SIGMA interchangeable lenses for Pentax mount are attached to the PENTAX K-1, the upper part of the mount can be scratched. This phenomenon is due to the interference with the shape of the upper part of the mount on the PENTAX K-1 camera body and it does not occur to any cameras other than PENTAX K-1.

    Reading through the Pentax forum article and a few comments it appears that the lens ever so slightly contacts the camera body and leaves a cosmetic scratch. Doesn't look like any big deal as I reckon more scratches are inflicted by clumsy owners mounting lenses on any camera brand / model.

    So far there don't appear to be any clouds on the horizon for the K-1, reading a few preliminary reviews and seeing image samples it is shaping as a glorious piece of gear at a very good price.
    Nikon, Fuji, Nikkor, Sigma, Tamron, Tokina and too many other bits and pieces to list.
