interesting design - the aperture seems to have many more blades than usual.

[Frank Fremerey]

Very interesting. Also the industrial solutions.

That could be Erlewine material

[Bjørn Rørslett]

Possible interesting, but that web site has a truly bad design and the stuff is difficult to read. Just keeps moving around ...

[Tristin]

Hopefully the new lens manufacturers keep popping up.  Interested in seeing tests of the Irix lenses as well as this one.  While Nikon cranks out the plastic AF lenses, perhaps we will get new quality metal manual focus lenses elsewhere.

On a side note, what is up with manufacturers not providing details on aperature blades for lenses?  From unknown manufacturers up to Zeiss, it is common.  Especially with a lens like this where they quite obviously are offering something unique in terms of the blades, you'd think they would mention it.

Is there any information on price?

[John Geerts]

The price is not released yet.

And a "review" or some real world samples.

The latter reference showed the lens has a propensity to flare, low contrast, flat colours, and lots of geometric distortion. Geometric vignetting, in contrast, seems to be acceptably low and the tendency to make 'cat's eyes' is apparently kept under control.

Further evaluation will have to wait until samples are released in the wild and price is known.

Had a look at the pictures here and realised that I recognised the scenes - the pictures are from Auckland city in New Zealand. Unusual for a prototype lens to end up here!

As for the number of aperture blades, some pictures here show diffraction stars with 14 points, so the lens has 7 aperture blades.

[Tristin]

I counted 14 rays as well, but the images of the lens shows a blade count certainly higher than 7.  Wouldn't 14 blades create 14 rays? 

[Roland Vink]

Yes, especially if they have straight edges and opposite pairs are closely parallel.

What Roland said.  The odd number of the aperture blades doubles the number of the rays of the star image.

[Tristin]

I'm aware of that Akira.  It definitely has 14 blades according to the images of the lens

Thanks for the image, Tristin.  You are right.  Now I would suspect that the aperture is not automatic (as in Nikkor "Auto"), similar to Samyang lenses of non-Nikon mounts.
