Essentially with this 15/f2.4 when coupled with the K1 full frame sensor, which will give an effective 1 stop advantage, this combination should be the equivalent (I know there is that "word" again) to the f1.8 (as with the cropped Sigma 18-35/f1.8 lens on a K3/5).

For the wide end of the Pentax full frame wide angle 15-30/f2.8, this should be a pretty good stop measure or interim solution.

Have you seen the reviews for the Tamron 15-30/2.8? Seriously good lens, better than the Nikkor 14-24/2.8. Just a shame Pentax want so much for it.

Yup! I have read quite a few of them. It would be the lens to get. $1450 is really not that bad, until you consider that the Tamron goes for $1200 (full retail at B&H) and the Pentax does not need the lens based stabilization (so probably about $1K - but who knows about the license fee to Tamron). So, leveling things out, even with the Pentax coatings and focus clutch - we are paying a premium - but not as much as the Nikon folks. Pentax is figuring that its less than the Nikon, so everything should be OK.

Tamron £850 . . . Pentax labelled version £1499!!! Here in Blighty. It's too great a difference.

A term "neutrino" is derived from "neutron" that in turn is derived from Latin "neuter" that means neutral.

"A lot of time and attention was dedicated to anti-reflective coatings, used in the lenses. Their marketing name, “Neutrino coating”, is supposed to indicate that they are spectrally neutral (flat transmission). Unfortunately if you know something about an elementary particle called neutrino you have to admit that name is a bit misleading…" Irix 15 mm f/2.4 in our hands - LensTip.com

I suspect the price will come down a bit after the initial buying surge is past. If it was $1,300 no one would care. Still even at $1,450 that is not bad, $250 premium? Remember, if Tamron released it maybe the price would be lower but they won't because the cost is too high for the lower expected volume. Price we pay for shooting Pentax. Maybe the K-1 will build market share and that will change but for now that is the way it is. Ricoh will take the extra margin, if there is any. But until someone holds both a Tamron and a Pentax side by side and examines them we really do not know what differences in build quality were added. Perhaps the extra is justified by the build, we don't know yet.

And the equivalent Nikon is $1,900 (14-24 f/2.8) And reportedly not as good. Talk about a premium...........

Blah, wait a year and the lenses will be a lot more affordable. Ask 150-450 early adopters....

Well, there are wide options out there that would cover full frame and be cheaper than the Pentax 15-30. Obviously the Samyang lenses, this Irix 15mm, and then, the Sigma 12-24. But, you do get what you pay for and my experience is that I often buy a cheaper lens and end up selling it to get a more expensive lens in the end.

But I would probably be satisfied with a prime in this range that is manual focus. I do a lot of landscapes and you don't need speedy auto focus for super-wide angle anyway. I'm more waiting to see what primes Pentax comes out with in this range.

The Irix front-lens diameter looks pretty narrow for a f/2.4 lens.... about 40% narrower than my A15/3.5 ... I doubt this would be influenced by the optical formula ?

What i still fail to see is somekind of seal in the mount, they just make reference to "sealed front element" i hope this dont mean the mount dont have this protection and make the WR just marketing slang.

Check this image - you can clearly see a rubber ring around the mount.

I see it now, i see the image in another angle and it seems like a part of the plastic body of the lens.

It's also written in the picture above:

Weather sealing - mount - yes (for both versions).
