The following link mentions that the Contemporary version of the lens Sigma 150-600 C will have the K mount available. The information per the Sport version of the lens does not mention the K mount availability yet. I emailed Sigma and a correspondent said the S version does not have the K mount available at this time. Maybe in the future it could be (all depending on time and what actually happens of course).

No Sir. It mentions the 180-300 lens being available in pentax k mount. There is no mention of the pentax mount for either 150-600 lens.

According to that link it will not be in K mount - only that 18-300 will be.

The all but orphaned Sony A will get the Contemporary version, but not Pentax K...

And that reputation has been around for decades. I remember showing my then new K10D to a few retired photographer friends, a few of whom shot Pentax 645 and 6x7 in the day. They started recounting how Pentax shooters in the 60s and 70s were perceived to be "cheapskates" (they used the same word) compared with Nikon shooters.

Ricoh will be pricing lenses to leave the remaining legacy Pentax customers behind then.

There is only ONE way to get third parties to make K-mount lenses, and that is for there to be enough people buying K-mount lenses to make it profitable. For better or worse, Hoya's positioning Pentax as a "budget" brand means that Pentaxians are less likely to spend the big bucks. So not only are there 8+ Canons and 8+ Nikons and 1+ E-mount for every K-mount, the K-mount owners are less likely to pay MSRP for high-priced new glass.
Actually, it isn't so much about the number of cameras sold in a given year as it is about the number of K-mounts in the market altogether (what is referred to as the 'installed base'). While the objective Ricoh had when they introduced color on camera bodies was, of course, to sell them to young Japanese women or as a second K-mount camera in a western household, the goal has been to dramatically increase the installed base of K-mounts in the wild. Ricoh doesn't care - Tamron doesn't care - Sigma doesn't care - what is wrapped around the K-mount. They only care that more K-mounts exist at the end of this year than did at the end of last year.

The reason is, of course, that third-party lens purchases happen after the camera is already owned. Maybe a 17~70 is a better lens than a kit lens. Maybe a long zoom is better for youth sports. Whatever.

It takes time and money to set up for a run of K-mount lenses. They're more complex because they have to have screwdrive [EDIT: Corrected - mechanical aperture actuator]. Sigma and Tamron won't sell as many as the other mounts - so the set-up expenses and opportunity cost is spread over fewer units. At a point it is apparent the necessary final retail price is prohibitive - you've breached the line of diminishing returns - so they just don't do a K-mount version.

When the installed base of K-mounts gets large enough again they'll make lenses in K-mount.

I guess that means racing to the bottom, as it seems like most of the recent offerings are more consumer oriented. It appears that they are framing the Pentax brand in the DSLR space to be more of an entry-level product. Have there been any truly new pro-level lenses released (besides the TC) during the past three years?

Have to have screwdrive?? My Sigma 70-200 does not have screwdrive and works great.

Sigma doesn't care about the screw drive. All of their recent lenses are HSM only. What they have complained about is the mechanical aperture actuator.

Sigma obviously considers a 150-600 to be less attractive to Pentax buyers than a gigantic 18-35/1.8.

LOL!
The 560mm was so out of left field, with goofy pricing and a mysterious audience, that it has the markings of executive vanity project all over that. Someone at Hoya wanted to make a point.

Those were props. Until a product is real and offered for sale, it doesn't count.

The 560 was just a prop a few years ago.

Keep looking at the past and you'll get left in the past.

Incorrect

My post information was incorrect. I had assumed that the article was referring to just the 150-600 S and C lens versions, not including others. I am sorry if anyone was misled.

A 150-600 would be sweet :-)
