A couple of new lenses in Pentax K-mount were introduced at Photokina 2012 from the two independent lens makers: Samyang and Schneider-Kreuznach. It is encouraging to see the number of available K-mount lenses grow even when it comes to expensive specialty lenses. The new lenses include a 10mm rectilinear ultra-wide angle prime, and a tilt-shift lens.
Samyang
We recently repoorted on a Tilt-Shift lens from Sanyang and it was on display. So was a new 10mm F2.8 super wide angle lens, the Sanyang 10 f/2.8 ED AS UMC CS. This lens is designed for the APS-C format and will be available early in 2013. We confirmed with the Samyang representatives that it will be available for Pentax.
The earlier-announced 24mm F3.5 Tilt-Shift lens (Samyang T-S 24mm F3.5 ED AS UMC) is also confirmed to be coming out for Pentax:
Schneider-Kreuznach
Schneider introduced a 28mm F4.5 Tilt-Shift lens called PC-TS Super-Angulon 4.5 / 28 HM Aspheric. The lens has a lateral shift of 12 mm and a tilt angle of 8 degrees. It is physically relatively big but fortunately furnished with a tripod mount. It is available in for Pentax K-mount (besides Canikon) and at this time only shown behind glass. The price will be in the EUR 2,000 to 2,500 range.

The three other T-S lenses (50mm, 90mm, 120mm) were also on display. These were announced at the previous Photokina event (in 2010) and they are priced between EUR 2,500 and EUR 3,000 and are like the 28 mm lens full-frame lenses.

What's hot about a lens with tilt is its capability to keep a slanted object in focus. This was illustrated with a 90 mm TS lens on a Nikon as seen at the top of the page. Below we show the demo set-up; the image (seen on the tethered monitor) is tack sharp over the entire area with rings.

Now that Samyang will produce a 10mm wide angle lens can I assume Rokinon will as well?
If the price is right, I will get myself the Samyang 10mm.
Any prices announced yet on it?
VERY interested in the Samyang Tilt/Shift, also nicely covers the 24mm gap in the pentax range :) I've heard whispers that the price is in the $700-$800 price range so not bad considering the prie of similar lenses in other brands and mounts.
Any idea on what could be the price of T/S Lens. I have been dreaming a long time, but the price has been always putting me off!
Regarding the CS, in a quick look through Samyang's lineup every "CS" lens is a lens designed for a cropped sensor, so I'm guessing thats what the CS stands for.
Does both lenses have AF??
Thanks. Any idea what the "CS" in the 10mm stands for??? Also, please ask Tamron and Sigma what their K-mount intentions are going forward.
Can you please check with the Sigma people to see if the three new lenses they have introduced will be available in Pentax mount?
Still too narrow on APS-C for a lot of architecture stuff. Arggghhh!
Actually what I meant is the 12-24 is sharp from at 12mm.
The Pentax 12-24 is pretty sharp wide open but I suspect this 10mm prime will probably have a slight edge in sharpness. Being one stop better will be interesting to use in lower light the field. I look forward to obtaining a copy.
That Samyang 10mm is very tasty!!!!!
I shudder to think what the price will be on these new sources of LBA but OMG, what I could do with a T/S lens...someday.
