Many Zeiss lenses are now manufactured in Japan (and have been for a while). In fact, all of them might be. But much, if not all of their R&D and design is still done in Germany. I think this may make it cheaper for them to source glass this way as there is so much lens manufacturing done in Japan/Korea/China. So the market might be better. As well as finding/retaining well trained technicians/employees for the actual manufacturing...

Just guessing here, but I'm thinking the "neutrino coating" may be something to combat/minimize Coma and to help with light transmission out on the periphery. Now, if they just put a Fluorine coating on the front and rear elements... 8)

More thoughts I have on this lens.
The website is impressive. very interactive. classic and simple. I like the design and the way they show the features when you scroll or click on them. That being said, I try not to get caught up in the WOW factor of advertising. But for a new company Its very interesting they can sell a lens at that price point and have so many features. strictly from and astro perspective, I hope it is as good in the corners as the page one picture shows. Any further analysis will have to be done through reviews.but I think its enough to make me order one and see for myself.
probably one of my favorite lens' is the canon 10-22 on and old T1i. I loved how sharp my copy was. and it was great for buildings and daytime. The Rokinon 14mm f/2.8 is also a nice lens. unfortunately both copies I had of that had some issue with focus left to right sides of frame. The Rokinon 12mm f/2.8 fisheye is fine for just what it is, I will keep this one. The Canon 16-35mm f/2.8II was great. The coma at the corners wasn't so great for astro, but having a zoom was handy. I could move to 18-20mm and get a nicer image (plus the filter housing would be out of the way at 21mm) nothing is perfect. Now the Tamron 15-30 is better, although (for me) no filters( screw on) that I want to carry extra. And I didn't want to go the Nikon 14-24/adapter route. So I have patiently been waiting with others for the Canon 16-35L III to arrive.
Now that this Lens looks promising I would pre-order it. I do still have questions. But I think I have found out how they plan to market this and make money. You buy the basic lens. Then, options. In the form of accessories. 2 bags. A few different ND density filter options. A UV filter and a CPL. IT will be interesting the price of these. Also, what kind of quality are these filters when compared against the top of the line B+W or Heliopan? which range from $150 to $700. will you be able to buy another manufacturers filter and use it with the lens hood? I would imagine so but have to ask that. Are the kit filters really good? We wont know and I don't know how you could find out. Maybe someone will test them against others? I'm sure if you don't purchase them in the order they will cost a lot more to purchase later. An extra thing I noticed was infinity click. I thought the exact spot on a lens for infinity changed with temperature and atmospheric conditions. I notice mine changes ever so slightly with temperature. I set it up each time.
Of course Ill get it and have a 15mm lens about the time there is a new and better 16-35 III Zoom. Wonderful thing to have options.

Hi there
What a interesting lens. Manual focussing and a lock switch! I love polar lights and I have dreamt many times of a lens offering a focus lock! In a poll (run by Canon) I asked them to create a wide angle zoom lens with a focus lock (e.g. the 11-24 mm lens - you just lock the lens for a selected distance. You zoom from 11-24 mm and the lens always focusses at the same distance). Wouldn't that be nice for star- and polar light-photography?
About the price: well, I am Swiss and Switzerland is only beaten by Norway when it comes to high prices. If this lens were manufactured in Switzerland it would cost $2000.--!
But designed in Switzerland and manufactured in Korea - sounds more like $ 700.--. Guess I have to plan my next polar light trip (I will post some polar light shots in a separate topic!) with an Irix 15 mm lens.
;D

Does anyone else like the idea that there is a "click" or stop at infinity? If it is accurate, that would be great. 
I really like that idea. Nice looking lens too.
It will be nice to see what coma is like.
I wish the company well.
Since I got my Tamron I've become very open to 3rd party if the product meets or beats Canon.

Hi!
Well, concerning coma it's not that difficult to beat the Canon 16-35/2.8 II or the Canon 14/2.8 II at the moment. The rumored Canon 16-35/2.8 III might be a more serious competitor to the Irix.
Concerning the denied relation with Samyang: There are two similarities with the Samyang 15/2.8.
The camera mount of the Irix is hold by only three screws as it was the case for the older Samyang 15/2.8. The recent Samyang version has four screws similar to my Canon lenses.
The lens composition is also similar. The Irix has 15 lenses in 11 groups with 3 x HR, 2 x ED and 2 x ASP and the Samyang has 14 lenses in 12 groups with 3 x HR, 2 x ED and 2 x ASP.
As both lenses are more rivals, it's probably more a new company founded by unhappy ex-Samyang engineers than a spin-off.

The Samsung lens group presumably was looking for work after the NX line was dropped, so these lenses possibly come from them. My guess is that the lens elements and aperture control were parts originally intended for the NX2 system, and the optical group adapted them to work with Canon cameras.

I took a few photos at f/2.5 with the lens on my 5Ds.
As they were hand-held with a pre-release lens, it's not fair to publish them, but my first impressions are that it's a good quality lens. It shows low CA, and a bit of purple fringing - both cleaned up well in ACR. Straight edges along the edges of the frame are not obviously curved, but at f/2.5 vignetting is quite noticeable (smooth gradation). Light sources in the corners of the frame show no obvious coma.
Hardly a comprehensive review, but enough to put it on my definitely to review list
Compared to the Samyang 14 mm I looked at a while ago, it's vastly better on distortion and the build quality is in a different league for either version of the lens - much closer to my old EF14 2.8L II

Hi Keith, was there any indication of UK prices and also, what about further lenses ? They have been posting about a 11mm f4, is there anything more ?

No details as yet - the 11mm was firmly in a glass box - looked slightly bigger.
I'm on their mailing list so should get info as soon as it appears.
The only clue was 'we're looking at interesting lenses' - could be anything I suppose ;-)

Thanks Keith for posting this. So at least we get a view of what they said it being capable with a high Mp Body.
Just as a guess, would you say it is sharper and less CA in the corners as a Tamron 1-30 or Nikon 14-24? maybe you've only had canon WA Lenses? Either way thanks for your post...And also thank you for all the work you put out on your website.

No idea about those lenses I'm afraid - without a direct comparison, I'm disinclined to match it against others.StoneColdCoffee said:
OK, noticeably better than the Samyang 14mm I tested (which wasn't bad on my 1Ds3) ;-)
The centre of the field wide-open looks sharp enough to show good detail from the 5Ds - but it was not the best of lighting...
When I get a chance I'll see how it compares with the ef11-24 - a lot lighter for one thing!

NR have a leak on the pricing for the 15mm, between $600 and $780 depending on which version is purchased. There's a polycarbonate body called the fire fly and a metal bodied version called the Blackstone.keithcooper said:

Now there's an informed comment from someone who obviously has taken more shots with one of them than I have...AvTvM said:
