I have K5 that is not properly recognizing my Sigma 18-250 lens.
I took 3 shots of the same scene using different lens to test the problem.
Shot 1 was with a Pentax 17-70 lens and the exif data showed it to be a Pentax 17-70 lens.
Shot 2 was with a Sigma 30mm lens and the exif data properly reported the lens.
Shot 3 was with a Sigma 18-250 lens and the exif data reports that it is a Sigma 70-200 lens.
I also sent a note about this to Pentax via their customer support web form and will probably try calling them tomorrow to see if there's a fix.
Has anyone else noted this problem with a K5?
