Irix 11mm f/4 full frame lens for Nikon F-mount officially announced

Irix officially announced their 11mm f/4 full frame lens for Nikon F mount. Additional information, including press release, MTF charts, specifications and pictures can be found over at PhotoRumors.

Irix lenses can be purchased at Amazon US, Amazon UKAmazon DE and Amazon IT. In the next few weeks I will be getting some discount codes for all Irix products, so stay tuned.

    Impressive center sharpness if MTF is true (though not unprecedented for a f/4 lens), But seems there’s going to be huge smearing at corners.
    Interestingly they didn’t make a smaller version for E mount. We now have crazy wide lenses with reasonable price and manageable size/weight, without using the short flange distance magic!

    • Adam Brown

      I’m not great at reading MTF charts… but it looks pretty weak beyond the dead center of the frame. Debating whether I want to be an early adopter or wait for reviews.
      I have a vacation end of June… I’m tempted.

      • EnPassant

        MTF is actually very similar to the measurements Lens Rentals did on the Canon 11-24 lens at 11mm.
        It’s very difficult to construct a super wide lens that is fully sharp in the corners at full opening. Stopped down to f/8-f/11 it should be much better.

        • Adam Brown

          Then I want it. I do most of my ultra-wide shooting at F8 on a tripod or in good light. I use the Samyang 14mm right now.. I like it but the distortion is a bit much.. and going all the way to 11mm really seems like it would be an awesome jump. And even the focus lock on the Irix may be very helpful on a manual focus lens. (Ultrawide… shooting at F8, I should be able to just pick a 2- foot focus distance, lock it there, and be good).

      • Spy Black

        I don’t know if this will be of help, but here is a test shot I took wide open at the Photo Plus Expo with the 11mm. This is the full RAW file. The only real “point light” sources I had at my shooting position were the overhead lights. While the lens has quite a bit of chromatic aberration at the edges (which is readily correctable), it still looks fairly sharp at the edges. I focused as far to the back of my FOV to get near ∞

        • Adam Brown

          Thank you. I do think I’ll pick up the cheaper version of this lens.

    • Jason Joyce

      Bet Irix is the sames as Sigma, they design one lens and adapt it to the various mounts.

      • The rumor was that Samyang is behind the brand:

        • Jason Joyce

          I was responding to Eric on why the E mount was not smaller. Thought the 3rd parties develop one lens and adapt it to each mount type.

          Is the Irix =Samyang’s “Upscale/Art” line 🙂

          • Moomin

            I don’t think so. Samyang has their own premium line coming up.

  • jmb2560

    Has anyone tested the 15mm lenses? I wonder if it makes sense to buy the ruggedized version versus the all plastic firefly. Since I won’t use the 11mm everyday, I may be just better off buying the cheaper one.

    • Eric Calabros

      Maybe you decide to shoot a waterfall in that particular day?

      • jmb2560

        According to the web site, the front glass is not weather sealed… That picture will be a one-off!

    • Spy Black


      • jmb2560

        So just like Nikon G lenses, right?

        • Spy Black

          Won’t dent or warp.

  • T.I.M

    It’s nice to see new wide angle lenses for F mount, maybe on day Nikon will make us a decent 14mm f/2.8 !
    (even a good Nikkor 15mm f/3.5 will make me happy)

    • RC Jenkins

      Yes. The current one is a bit disappointing, and the 14-24 is great but out of reach for a lot of people.

      14mm (or anything ultra-wide, really) are some of the few focal lengths where I truly value clinical corner-to-corner sharpness.

      The tests should be: “How well does it shoot the Milky way and straight architecture, and how sharp are the details?”

    • Viktor

      Yes it would be nice…. but I do not understand your logic – if you are not happy with the quality of that Nikkor, go to this IRIX, or Sigma will have a 14mm as well…. in a while on the shops – hopefully.
      I am not going to wait till Nikkor does something…… Sigma 14mm looks great and these IRIXes (15, 11) look good too.
      And at least the Nikkor will not be available at this price range 😀

    • duh 14-24

      • T.I.M

        I had the 14-24mm f/2.8, too much distortion.

        • Banan Tarr

          which is fixed with the press of a button ?

          • T.I.M

            You can also make a 36mp picture from a Nikon D1 by pressing a button…

  • Spy Black

    It’s about time they finally announced this officially. Hopefully the production samples will be as good as the the lens they had over at Photo Plus Expo.

  • Adam Brown

    I want. Discount code please! Lol

    • I should get them in 2 weeks. Stay tuned.

      • Adam Brown

        Lol. Looks like the lens isn’t going on sale till the end of the month, so there is some time.

  • Robert Bell

    It’s nice to see some manufacturers making compact f4 prime’s.

  • TheInfinityPoint

    The flare looked pretty bad in the video, for the people who don’t like it in their shots. I also see some ghosting from the lights. The MTF curves kind of didn’t make sense…there are 3 curves labeled as “S” for sagittal direction I presume. I’m guessing the dashed line is tangential, in which case that is some massive astigmatism there. 11mm is certainly special as there isn’t much below 14mm these days. On the other hand that sigma 14mm f/1.8 looked really good, I may get that at some point for my astro-landscape work if coma correction is good.

  • Viktor

    One thing I do like about this new company is their Customer/Premium policy with the same optics. You can buy the premium model with magnesium, better weather sealing etc. for higer price, but also a plastic cheap version with the same optical performance. This seems to me fair to the customers.

    • preston

      They state that the weather sealing is the exact same in both versions. The only difference is look and feel. Optics and weather sealing are identical.

      • Viktor

        Last info I had was that the weather sealing is full on the Premium one and the cheaper version does not have sealing on the front element of 15mm (has on the mount and focus ring)…. [also in alliance to official info for 15mm on the site of IRIX:]

        And yes, you are right for 11mm it is the same as both versions do not have front element weather sealing…. others are equal 😉

  • Viktor

    Wish good luck IRIX in its career, looks attractive and there is still large gap in the lens market – expecially in small lightweight precise wideangle FF lenses.
    18,20,24,28 – f/2,8

    – Sigma makes high speed lenses f/1,4 which are bulky, heavy and no filter usable…….
    – Nikkor used to make f/2,8 which are old and unusable nowadays….. or f/1,8 which are softer then their 1,4 and the build quality (no comment)
    – Zeiss are expensive and heavy anyway…..

    For landscape, architecture, interiors, travel – photographers do not always need heavy 1,4 wideangle bulky lens……

    Give us f/2,8 or even f/4 lenses crispy clear and brutally sharp to the corners even wide opened with light weight magnesium body (and consumer plastic version), manual focus, filter mount, and I buy it right away 🙂

    • Captain Megaton

      I’m getting tired of every new lens announced being a 1.1kg $2000 monster. I’m recently gotten into the AF-D 24/28/35 and am enjoying the convenience and fun factor of 200g/$200 optics on FX.

      • Yup, folks who cry for a lens that is sharp at f/11 usually need look no further than an old N-AIS prime, or an AF-D prime.

        Actually the f/1.8 G primes are a great option, extremely sharp at f/11 and yet still very fast, (very sharp wide open too, through most all of the frame) …and yet still lightweight and compact. The Nikon 20 1.8 G versus the Sigma 20 1.4 A is a laughable comparison, for anyone who hikes miles with gear on their back. The added weight just isn’t worth it.

        • Viktor

          Yeah, the old lenses AIS / D gives this combination of low-weight and good sharpness at f/11. Current 1.8 Nikkors are OK with their weight, however they are still fast and not so sharp used on D8xx 🙁 For 12,16 or even 24MPix they are OK, but on my D8xx I find them softer the whole way to f/11.
          That is why I think making slower f/2,8 or even slower, but with precise and sharp optics would make many landscape photographers happy 🙂 I really do think such lenses would go out of shop as bread and butter….

          • Which lenses did you find inadequate until f/11? I had a D800e for a while before I went back down to 24 megapixels and I found all of the f/1.8 G’s that I tried to be extremely sharp by 2.8 or 3.5, unless you count the extreme corners in which case yes especially the wider lenses did suffer…

            • Viktor

              I did not go down, so I have stayed with 36MPs 😀 And yes you are right, I am talking mainly about the extreme corners as for landscapes and wide angles I do like sharp corners….

              Otherwise being professional in portraiture, I do not mind soft corners there while the center is sharp.
              Those 1.8Gs I have tried were not actually bad. For D700 realy great low-weight gear. However comparing them on 36 sensor with other in detail they were simply softer (Nikkors 20, 24mm compared with Nikkor 24PC, Zeiss 25/2 and 18mm…. also compared with 24mm Sigma, but eventhough having and loving 35/1.4 I did not fell in love with 24mm Sigma wide opened).
              That is why I think Nikkors 1.8Gs are made to 24MP cameras and then it does not add much in sharpness. Having still D700 as my main camera I would not say a word against them, but…..

            • If you’re talking extreme corners, I don’t think AI-S or AF-D lenses are any better in the *extreme* corners, not for 36 MP with no AA filter. Not wider than 50mm, at least. And Sigma Art has been underwhelming at 24mm and 20mm, even at f/8. (I reviewed the 24 1.4 Art and 20 1.4 Art on the Canon 5Ds, THAT was a revealing investigation into the extreme corners!!!)

              Really the only Nikon lenses that rock 36 MP with ease are the 14-24 and the 16-35, and of course the 24 PCE without any corrections / tilts applied. Other than that, you’re hard pressed to find random gems that truly get crazy sharp in the extreme corners by f/8 or f/11. Aside from, like I mentioned elsewhere, Zeiss.

            • Viktor

              I do mainly agree with you in these two paragraphs.
              Yes 14-24 is great (do not own it, just tried it), 24PC is simply excellent (for around the same money as 1.4 I would never go to 1.4 version, 24PC is one of their greatest lenses eventhought I have read while ago, that someone had issues with his copy….. I think it was even at this site somewhere, do not know now).

              You surprise me with stating 16-35/4 here, I did not like that one…..

              However you are right its hard to find any 50mm wider with sharp corners and I agree with you about those two Sigmas, however, that is why I am calling for making f/2.8 or f/4 small, light, weather sealed, but optically perfect lenses.
              Unless doing astro you do not need 1.4 20mm but sharpness and saving of material 😀

            • Again, if you’re not doing astro, then an f/4 lens is usually going to be used at f/11 anyways, in which case a 16-35mm f/4 is quite a decent performer. It probably weighs slightly less than, say, a flawlessly sharp 16mm f/4 prime AND 20mm f/2.8 AND 35mm f/2.8… (The 35mm f/2 D is incredibly light, as is the 20mm f/2.8 D, however neither are really that perfect until you get to f/11.)

              I’m still with you, though, because a far lighter lens in your hand (or around your neck) is worth a couple extra ounces sitting comfortably in your bag. I would LOVE to see Nikon revive their 15mm and 13mm prime designs, because I suspect they could achieve superior sharpness in a far lighter package, compared to the old AI-S designs, thanks to modern optical engineering.

              Unfortunately, I think we’ll be stuck with the existing f/1.8 G primes, as they are already quite decently lightweight and rather sharp by f/2.8, let alone f/4 or f/11. Yes, they could be better for the D810, but then again almost every lens could be a little better for the D810. And that’s why I hope we see a new set of super-sharp optics sooner or later, from SOMEBODY lol. Maybe Tokina will update their 17-35 f/4; Tokina always does *insanely* sharp corners in their modern APS-C ultra-wide zooms. The Tokina 12-28mm f/4 DX is probably the sharpest lens in that zoom range & weight class that I’ve EVER tried. Nearly flawless right to the corners, wide open even, and just eye-popping sharpness at f/8. And that’s on a DX sensor with 24 megapixels and no AA filter, so you KNOW it’d resolve a D810 just fine if it were designed for full-frame!

            • Viktor

              Yeah Tokina….. you surprised me with this one, I have unfortunatelly forgot about that company. Years ago it was a manufacturer I believed they will come up with something and I will have at least one their lens. I honestly did not hear about that company for some time and that is sad, they were not doing bad things and the feel I had from them – good optically and also felt like good quality in hands. But I have just tried them in a shop so cannot say more. I surely give them a chance when I come across them 😉 Going to look at their pages right now…. However I am primes fun and I know they were more towards zoom lenses….

            • Tokina has always really excelled at sharpness, they making impressively sharp glass long before Sigma Art and Tamron’s new stuff came along. Especially their ultra-wide options; the 12-24 and 11-16 were classics and worth every penny. Their modern 12-28 and 11-20 are an improvement and a great reason for a travel / ultralight shooter to never think twice about selling off their APS-C body if / when they upgrade to full-frame.

            • Viktor

              Zeiss – yes, I did work with 55 and 85 Otuses so I know they are perfect, however I did not still have 28Otus in my hands. I believe that one is great……. but also great in sence of huge……
              While having 55&85 on tripod in studio, cannot imagine walking aroung with their 28mm with around 1.4kg (50oz) 😀

            • A friend lugged the 85 Otus up a mountain, for this shot. It was not easy…

            • Viktor

              Great, well done 😉 Not a piece of gear I would want to carry anywhere 😀 In studio it was enought for me 😀

      • Viktor

        I did use these years ago. I did enjoy them on my old FM2, it was not a trottling combination on my neck and my backs were happier 🙂
        However these lenses being good for film, they are nowadays optically weaker for digital sensors. Till 5,6 they are not prepared for good performance on current sensors and landscape usability starts at 8 more at 11….
        I still have 28mm to carry out with FM2 (also for its aperture ring which is not understandably missing on the new lenses – such a useful and ergonomically easy to use thing).
        This is why I do think there is a gap in the market with sharp leightweight weather-sealed well-priced primes f2,8 (or even f4). I would buy them as bread if someone makes them (18,20,24,28mm whatever).

        That is why I think someone like IRIX could use this gap to get to the market and succeed.

        • Even Sony who specifically avoided fast pro glass for a while could not (at first) make a decently sharp lightweight compatible prime for their FE A7R. You had to buy Zeiss if you wanted a sharp 2.8 prime…

          • Viktor

            I do not know Sony lenses (at all), but looking at Zeiss gear even there (especially f/2.8 lenses) one has to be carefull. Their 28/2.8 and 25/2.8 were not really good…. again especially in the corners.

            • Captain Megaton

              I think your expectations are out of whack. Just because you have a 36MP sensor doesn’t mean your lens must outresolve it. Who made up that silly rule!? Look at it this way: a high resolution sensor gives you the confidence that your photos are always limited by either the optics or stability constraints. It is “enough pixels” and you can now forget about them.

              The 25/2.8 ZF is a great lens by the way. Well corrected and excellent (understatement…) center sharpness. It is, however, a 25 mm focal length optic. You need to be reasonable about what to expect for corner sharpness in a wide angle prime. Doubly so if you also want it small and cheap.

            • Viktor

              I do like Zeiss 25/2 however their 2.8 version did not convince me. I have tried it only once in the shop, maybe I did only bad testing photos, I do not know. However I did not like their 2.8 25 and 28 lenses 🙁

              Yes you are right, it is hard to expect miracles in the corners from wide angle lenses, but that is what I am calling for: make f/2.8 or f/4 wide angles with maximum corner sharpnes, low weight, only manual focus and I’ll be happy – I have nowhere said they have to be cheap….. 😉

              PS I am not an MP insisting, I would buy future D8xx even with again 36MPs. I even do think 20MPs are enought for many cases. However time has changed, technology has changed and therefore 2.8D lenses are unfortunately not enought nowadays while they were good years ago….
