Anyone using the new Irix 15mm 2.4 lens?

Really interested to know how it performs but cannot find many decent reviews.

Saw this and the even wider on the Photokina fair last week.
The better versions with more metal fell very good, don´t can tell much about the more plastic versions.
I had no good parallel adapter with me, and the had their Sony E mount adapter not ready, so I could do no good first tests.

It looks well built, the metal one, and is half the price of the Zeiss....at least!

Hmm, not a good night sky lens and it seems to have a flair problem
