That new lens looks really interesting. Limited build style so far. Is it a 35mm (too close to 40XS) or 21mm?
Talk about a really small lens/camera combo. Loving the K-01 concept to date.

Ouch, is that a mirrorless lens only, or is is standing on something?

Well, it's going to need a funky rear cap, that much is certain.

My bet is it is a 28mm F2.8, for mirrorless only because of its giant butt

I wonder if there's enough space where the mirror used to be to allow deeper lenses AND not screw up the angle of light hitting the sensor. Symmetrical designs like the Biogon are great on film because film grains don't care about the angle that light hits it. Digital sensors are quite a bit more picky. Still, if they could make a 28,, lens that performs as well as the other limited lenses, I might be able to get by with a single walk around lens...

maybe even a 21 reworked?? Or if there is a FF mirrorless on the horizon maybe this is a FF compliant mirrorless pancake normal lens

Its a bit disappointing that they can't work on the standard SLR. The 40XS design is also apparently a fixed focus lens,
That would be like saying Its a bit disappointing Apple can't work on the iPhone 5. It's unreal that people think the 40XS is a fixed focus lens since the specs say it will AF as close as 15.72". So @F2.8 this 60mm (FF eqiv) lens would have a DOF of 0.4in !

So how long do we need to wait for REAL information on this mystery XS lens? It's already Thursday in Japan -- but early morning. Will we learn more today?

(For the record, I'm going to guess 23mm f/2.8. Because why not? There's no reason to be constrained by existing Pentax lenses, since this apparently has a new lens formula.)

I know that K-01 has the same flange focal distance (k-mount). However, since it doesn't has the mirror inside the camera. Can pentax make use of the space and make the future lens much smaller (as if part of the lens tube sit inside the camera)?
I doubt this can be done. There is just too little space inside the camera.

Maybe only with very simple and slow lenses using small elements and minimal mechanics (no zoom / collapsing mechanism helixes). If i look at the back of my lenses, many of them, not even fast ones, use up quite a lot of the area mount offers. They could be shaved down a little, but i don't think as much as would be required to fit them in the sensor sized box.

But hey. If they can stick a reasonably bright (f/2) 16, or 24 mm "pancake" down that hole, i might change my thoughts about the K-01.

And at f/2, without counting in any element housing tubes, guard spacing or any other technical details, knowing the K-01's APS-C (23.7 x 15.7 mm) sensor size, you could fit a 15.7*2=31.4 [mm] or wider lens in there.

BTW, the diameter of Panasonic's 20/1.7 lens optical elements is roughly 21mm and that is for a non-retrofocus lens.

A birck has been shat! It seems that they will actually stick it down the box, good... good...
Front element looks bigger than this:

What you think about curvature? Looks like retrofocus to me and the outter surface of front element has less curvature than inner one. At this distance and size, i'd say 20mm or less. Front and rear element sizes visually remind me KIT lens, so i wouldnt be too optimistic about the speed. The finish certainly looks like LTD.
