Now the lens maker has announced that it is ready to replace the parts in its lenses which are creating problems for K-1 users. The problem wasn’t that big. Some Sigma lenses were leaving a small scratch on the upper part of the Pentax K-1 body because of shape difference. The company has also released a list of its current and past lenses which are creating all the problems. The list has been given below:

Sigma has also issued an advisory to its current users not to use the lenses with the Pentax K-1 till the repairs are completed. Sigma has also said that some of its lenses are not automatically recognized by the K-1 and its users would have to manually enter if the lens is question is designed for full-frame or APS-C sensors through the camera’s menu. Whether this issue will be fixed or not along with repairing the shape difference finds no mention in the press release.

    But Pentax doesn t make bodies for Sigma lens users, it makes bodies for Pentax lenses and if Sigma had paid attention to Pentax lenses instead of just Pentax bodies they would not have designed their lenses this way.

    Am I supposed to replace my tack-sharp Sigma with the shorter Pentax 60-2m f4?
