Not that I know of; but there IS a 16-35 f/2.8 > EOS (SLR) Camera Systems - Ultra-Wide Zoom - Ultra-Wide Zoom - EF 16-35mm f/2.8L II USM - Canon USA Consumer Products

I don't think you can find that kind of lens so easily. Full Frame 17mm takes quite a bit of glass and money to design and manufacture. I'm not so sure it's worth it.

that looks like EOS and F mounts only

EDIT:

Sigma 17-35mm F2.8-4 EX DG ASP HSM. It's a DG, so it should be full frame, and comes in K mount, though i don't believe HSM is on the K mount. i don't think you're gonna get any luck on the F2.8 constant though...

FA J 18-35 is full frame.

Pentax Lens Review Database - 18-35mm F4-5.6

If you really want wide angle you have the F 17-28:

Pentax Lens Review Database - 17-28mm F3.5-4.5 Fish-Eye

Neither of the two are the sharpest game in town but fun to use.

And neither of the two even come close to f/2.8

And neither of those are full-frame, as the OP specified.

Pretty much agree with ftpaddict. My first thought when reading the thread was the Canon 16-35mm f/2.8. It costs around $1400. Pretty cool lens!

Now the Tokina 11-16mm f/2.8 gives you more or less the same FOV on a APS-C sensor as the 16-35 would give you on a full-frame sensor.

yeah, but he could be using it on a Full Frame camera

People still shoot film, ya know...

And i don't think i've seen that for K mount either

(would love to be proven wrong though )

True re. shooting film..., but the OP really didn't give us much indication of why he needs a full-frame 17-50mm f/2.8.

As for the Tokina 11-16mm, I think we'll eventually see a Pentax 11-16mm f/2.8 as Pentax and Tokina "share" many lenses. The 10-17, 12-24, 16-50, and 50-135mm are some "Pentax/Tokina" lenses. Pentax for Pentax mount, and Tokina for Canikon.
