On a related note, when Popular Photography reviewed Sigma's NEW ($3,500) version of their F2.8 120-300 lens in the October 2013 issue, they ended the article by saying that the OLDER version is now available, while supplies last (same aperture) at $2,500, with a comment something like, "So Pentax and Sony shooters, SNAP ONE UP, because the new one isn't available in your mount." WELL, if those folks paid attention to what they're doing, they'd know the OLD one wasn't available in the Pentax or Sony mount, EITHER! HOWEVER, I was perusing the Sigma website recently and found a page where they said that you can send certain select lenses back to them to have them retro-fitted to whatever mount you use. From what I saw on the website, that service is available with only a handful of their lenses, and the price seems to vary based on the size and/or cost of the lens, with the 120-300 being one of them. I believe the cost for this lens is about $250 to have the mount changed, and of course they clean, re-calibrate, whatever... But you have to pay freight and insurance to ship it back TO THE FACTORY IN JAPAN. That may be worth if if someone REALLY WANTS that lens in a Pentax mount. Then again, aren't there mount converters for Nikon mounts that will work on Pentax cameras? My math tells me you'd end up spending $2,500 for the older lens, plus another $250 + whatever freight and insurance to Japan is, for the retrofit... so still probably well less than $3,000, when the new lens that also isn't available in Pentax mount is $3,500. Of course if the new one is worth the extra $$$, one could do the same with it, I guess. It all comes down to what you need and want, and what you can afford.

Hi Jeff,

There was a thread about that a month or so ago. I think it was determined that it is only for the newer Sigma lenses. And since ther is none in Pentax mount then you cannot have one changed from Nikon, Canon, etc. to Pentax.
