So who is designing the new lenses for Pentax? Maybe that's a question for Adam at CP+.

was this a real lens at the time? planned at least?
I really love the form factor of 40mm limited.
It was a prototype lens for the K-01 that leveraged the fact that the K-01 has no mirror to move the optics into the empty space freed by removing the mirror while keeping the registration distance. Since Pentax appears to have shelved the idea of k-mount mirrorless, I don't think we'll ever see it.

Maybe somebody is happily using it. It seems to have a to big front element for 40 2.8.

The 40mm XS having been released with the K-01, the never-released prototype is definitely not a 40mm. My personal guess is it's a shrunken DA21. But no specs were ever released, AFAIK. But we are drifting off-topic from the roadmap...

Probably extended to far back for a dslr body. We'll just have to wait for people wrecking their brand new FF with the DA 40mm F2.8 xs.

The 40mm XS has no optics protruding into the mirror box, which, I guess, is why it was released with the K-01 and the prototype was not. (Had the K-01 been more successful, they could have released mirrorless-only lenses.) The 40mm XS (which is still on the roadmap, BTW) should work on any Pentax camera that can deal with a screw-drive auto-focus k-mount lens that has no aperture ring. Might be crop-mode only, but won't physically hit the mirror.

The distance scale looks an awful lot like the 40mm ltd. This might even be a photoshop I thought the xs also had the protruding bit, just not as long.

It wasn't on any of the roadmaps I could find but is was always on the website. In my search I found one lens that never made it though.

Ah yes, the mythical 12-400mm f2 pancake zoom! Can't wait to see this on the roadmap.

One of the worst decisions Hoya made (and that is saying A LOT) was letting Hirakawa Jun go. Conversely one of the smartest decisions Tamron ever made was hiring him immediately.

Not that I shoot 645, but what happened to the recently released 25mm lens?
It was already gone in August 2014 roadmap.

Ask this in Adam's thread requesting questions.

Looks as though the DA* is Gold and the D FA* is Yellow. That will look good on some of the new K-S2 colors.

So at FF launch there will be:-
<snip>
maybe 40/2.8, 70/2.2 & 60-250/4
My test of the 60-250mm on a film camera shows full coverage, but softness at the wide end and significant (but not total) vignetting at the long end. More like the sort of corner-quality you get with a kit lens than a pro lens.

This is an important thing that a lot of people are forgetting. Crop mode seems like a great way to get many of the benefits of FF (much lower noise at high ISOs, etc) even if you don't have FF-compatible glass yet.
One more thing to remember is that the HD 1.4x Rear Converter expands the image circle of a lens. When I tested my DA lenses on a film camera with a Kenko 1.4x converter, it made them more like FF lenses. (It even worked to some extent on the 10-17mm Fisheye!). I hope the Pentax converter doesn't have any traps in it that would stop it doing the same.

I'll just be holding my breath for an updated converter that works with my old FA glass.

And all DA lenses will work in crop mode.
And if Nikon's experience is worth any input.....no one will care.
