SMC Pentax-DA 35mm F2.8 Limited Macro

Hi
I bought DA 35mm 2.8 lens recently second hand and for some reason it registers itself on my k3 as a 38.5 mm lens. Has anyone come across this and can it be changed.

Could you attach a photo straight out of camera using the attachment button? Would be interesting to look at the metadata.

Here is one, i had a look at the previous pictures and there are some that have registered 35mm but not many. I did have to open the back of the lens as there was a long fibre under the back element which i removed. Just wondered if it may have something to do with it.

Fixed your link (to use url tags instead img tags).

Definitely looks like the camera recorded 38.5mm as the focal length. But the lens ID indicates an unknown lens. Could it have been a zoom? Either that or the data was just corrupted.
