Sigma Offers Part Replacement To Prevent Lenses Scratching Pentax K - 1

Sigma offers part replacement to prevent lenses scratching Pentax K-1Lens manufacturer Sigma has announced that it will replace parts on its Pentax-mount lenses that are known to scratch the new Pentax K-1 full-frame camera. The company says that certain lenses that it produces clash with the shape of the upper part of the mount on the K-1 and that using one of the listed lenses ‘could leave a small scratch on part of the camera body’.

Sigma has issued a list of current and past lenses that it knows create a problem, and advises Pentax K-1 owners not to use them until the repair is carried out. Three current lenses are included in the advisory: the 30mm F1.4 DC HSM Art, 35mm F1.4 DG HSM Art and APO 50-500mm F4.5-6.3 DG OS HSM. A time scale for the repair service to begin has yet to be announced though.

The company also says that some of its lenses are not recognized automatically by the K-1, and that users will need to manually enter whether the lens is designed for full frame or APS-C sensors via the camera’s menu system. The announcement makes no mention of whether this issue will also be fixed.
