I came into this thread excited by the fact that a manufacturer deigned Pentax worthy of creating a new full frame lens in K-mount--surely a positive sign for our brand's future. Why people would rather snicker about a nonsense marketing term (a crime committed by ALL manufacturers) instead of recognizing this strategic decision is beyond me.

Ditto.

It matters not what term they use for the coatings. Could be banana coating for all I care.

From the looks of it and given the fact that a 95mm polarizer alone costs you $150-200 my guess is that this lens will be in the $1,200+ range, if not beyond $1,500..

The cost indicated on another site is - for the weather sealed one is going to be around £500/€600 and the non weather sealed version will be £400/€500 - with an expected June delivery. So €600 is $676 at today's exchange rates.

You have to wonder how this is going to compare with the re-badged Tamron 15-30/f2.8 that Pentax is offering. The Tamron with Nikon/Canon image stabilization is something like $1200. The Pentax version with out IS is pegged at $1400, so perhaps a $400 premium.

There's also 11mm f4 coming soon: 3rd picture

NOW we're talking. I don't think the 15 offers much over the 15-30 except the ability to use filters (which I recognize is not insignificant). Half a stop is negligible these days - the K-1's sensor will EASILY make up for 1/2 a stop, especially considering how large that lens is. It might be even larger than the 15-30!

But 11 is an outstanding compliment to the 15-30 for ULTRA ultra wide when the niche need arrives. Right now Canon has a monopoly in that end of the spectrum thanks to their highly praised, albeit astronomically priced, 11-24 f/4.

I'd be satisfied with that pairing, and add the Samyang 12mm f/2.8 FE for full frame (apparently only available for K-mount by special order at the moment), and UWA would be 100% covered as far as I'm concerned.

Please IRIX, release the 11 f/4 and then move to tilt shift lenses, starting with one around 18-20mm

You mean beyond the fact that Mattel made a Ghostbusters toy called a Neutrino Wand?

I must get one. I'll give all my lenses a neutrino coating.

I think this has not yet been mentioned: for what it's worth, Hubert Adanczyk, chairman of TH Swiss as pointed out by ogl, is also the owner of foto-tip.com, a Polish webshop with very attractive prices for Samyang gear (I have shopped with them and can recommend them).

[Mistral75]

You think it's more pricey than the limited? This is hard to believe since the limited is 700€ and AF. All the samyang Glas is under 700 with manual focus as the irix. My price tag guess (and wish) would be 4-500€

I think you are in for a huge disappointment. The Zeiss Distagon T* 15mm f/2.8 ZE/ZF.2 is around €2,700. Even if the Irix lens doesn't benefit from the Zeiss aura its positioning, at least marketing-wise, is clearly high-end.

[FantasticMrFox]

... the Samyang 12mm f/2.8 FE for full frame (apparently only available for K-mount by special order at the moment) ...

Wait, that thing is available for Pentax?! I have been lusting over that lens for some time now as it is wider than the 14 and 16 mm but can still take filters, unlike the 14 mm. Do you have any information on how to order it, and how much it costs?

we will see in a few days, but when its above 1200 bucks I don't think I would plunge my money into a prime, but go for the DFA 15-30 then, which is ridiculously high priced for me as a hobby/amateur shooter.
I wished that this lens is something similar to the amazing Samyang lineup or the Venus lens (ok its f/4). Btw to me the lenses of SY and Venus look also of higher value. I would say the marketing buddies of Irix have done their homework

I don't care for the name of their coating.... even if they call it "nutella coating"

If you read, it is priced arround 600€.

A DA15 new can be got in France for 480€ on Amazon and likely you can find it used for 300-350€. 700€ for DA15 date back to before HD version introduction.

Theses day a Samyang 14mm is also arround this price 350€ on Amazon and a 16mm f/2 (dedicated to APSC) is a bit more than 400€.

The reason to not choose DA15 over the other primes is not price. This may be border sharpness or max apperture or FF support. This may be to get a zoom instead for example the sigma 8-16 or 10-20 as to cover more range. But this is not really for price. And this is not at all for contrast, flare resistance or size.

It appears you saw 12mm and ignored the rest

12mm f/2.8 FE (Fisheye) for FF (full frame)
12mm f/2.0 CS (Crop Sensor) is what you are thinking of. I have no information about this lens. First I've heard of it, actually.

I did read the "f/2.8 FE" part, and was confused for a second, but as I was not aware of the fish eye lens, I simply assumed you had mixed up the aperture, and I did not know that 'FE' stands for fish eye, rather I assumed it would denote some sort of lens element (e.g. fluorite element).

Adamczyk of course.

There is a wide open full size sample shot from a EOS 5D Mark II here: Irix Announces 15mm f/2.4 Lenses for Canon EF
Not bad at all despite some purple fringing (although the astro guys must decide if that's a problem).
Sorry for linking towards the dark side.

[ogl]

it's awful level of noise in shadows.... as for picture - not bad for 2.4

Just something I noticed....That's called a monopod baby. It's for putting your camera on. (No not your iPhone).
