Taken off my Facebook feed today. This is what Sigma are advertising, so "Mount conversion service" may include Pentax. May be old news, but i'm new on here 😂

Sigma will only convert a lens to another mount if they already make it in that mount to begin with.

I don't know whether the K-mount is included in the conversion service; the other mounts are much easier to swap as they are all electronic, but the Pentax version needs further internal changes.

Thanks Mike-P for helping clear the matter up.

I thought I read somewhere that, for example you could change , say, a 150-500mm from Nikon to Pentax as that mount was made for that lens. But not a 150-600mm (new) Nikon to a Pentax mount because that lens has never been made in a Pentax mount. I could be wrong but that was my understanding.

Presumably means (to clarify further) it's not possible to convert a lens to a mount other than that for which the lens has already been released in.

And therein lies the problem, given Sigma and many others are no longer making new lenses in the Pentax mount.
(And as an aside, when they do, they strip the image stabilisation out also, which is limiting for video, where Pentax don't use the real sensor shift either.)

Assuming the bodies were the same though, it does make you wonder if you could take on the lens conversion yourself, if you could get ahold of the parts.
Good post, gets one thinking
