There any page with pictures out of the ones from the manufacturer or a page with first impressions?

Coma is no better than Samyang 14mm F2.8.

Which you kind of make sound like a bad thing, but actually the Samyang is known to perform extremely well on that front and is thus a staple for night sky photography, even for those who already have e.g. a Nikon 14-24 f/2.8.

The Samyang also has amazing resolution, what it's lacking in seem to be quality control (loads of decentred ones out there) and work against bright light/flare control.

this is cheaper, and faster also has some neat features in the more expensive version. Hope we'll see few reviews to see how it stacks up optically

This does not look like "a page with first impressions": Irix 15 mm f/2.4 - sample images - LensTip.com

In my opinion none of these pictures are sharp, or did I get something wrong?

After seeing the Lenstip photos, I would prefer to get a Samyang instead. Or maybe even Zenitar 16mm!
This is why I am always reserved with hyped up lenses until I can see sample photos by reviewers and users. I am not dismissing the lens yet, but those photos definitely did not convince me.
That said, the lenstip sample photos used the Canon's lowest jpeg sharpening. I would like to see a couple raw files before I completely make up my mind

I think the photos look OK. The big thing is that distortion seems pretty well controlled, which the Samyang can get pretty strange with architecture sometimes. If you are shooting landscapes, then probably any of these would be fine. Sharpness could be bumped up a little on several of those as per the photographer's taste, but they chose fairly neutral settings. Some are softened a bit by being shot at iso 800 as well.

I will suspend judgement until I see shots from it on the K-1. Pixel shift in particular should test its resolving power. Otherwise, the Irix looks promising.

With all respect for Lenstip, some of these samples appear quite a bit front-focused to me.

I'd say that yes those pictures looked soft, and just as stated before me, it was low JPEG sharpening. Some of stuff that looked interesting, mostly corner performance and distortion, or lack of it when comparing this to SY 14. I just did some shooting with my SY14 and it is quite good on lot of things, but taking filters and corner sharpness and distortion is not good at all. For the money samyang is great!(on FF it suffers more than APS-C)

Even at F8 the lower right corner here http://pliki.optyczne.pl/iri25/iri25_fot14.JPG ist not really great.

Generally the optical performance seems very balanced to the Samyang. The price is +60% (for the cheaper version), so it all is amtter of personal preferences again.

I do agree, it is not so good, but top left corner does not look so bad, couple of other shots might have looked better with different focus too. But as i said corners still looks better that SY14 in general, besides, SY 14 corners are poor, even at F 11..on FF that is.

Isn't this a manual focus lens?
