    Oh a slider for an ND filter on the back of the lens nice and thought full

    • Ethan

      Copied from Sony design.

      • J.Coi

        Copied from 1960s lens design.

        • BP2012

          Visually It looks like some of the old lenses like famous Takumar 15mm f/3.5 but optical formula is different and have much more elements. Those old lenses does’t have more than 11 elements, most complicated versions from 1970s have 13 elements, but this Irix have 15 not to mention new type of glass, coating, etc…

          • J.Coi

            I only talk about rear filter slot.

          • Chris Lane

            Just how different can you make a rear filter slot?

      • Duncan Dimanche

        copied from who gives a damn ! as long as they do it.

        15mm at f2,4 with filter threads is pretty amazing !! on a full frame ! It’s manual focus right ?

        • J.Coi

          Lens has no filter threads.

          • BP2012

            95mm filter thread.

        • sophia

          ur right, it is manual focus

      • Seeker

        hope not… it will sure suck then.

    • Zaphod

      Wonder if you could use it for a homemade APD filter too.

      • Jeffry De Meyer

        I guess you could

      very common in pentax lens

  • J.Coi

    This optical company don’t know what is the difference between “fluorescent” and “phosphorescent”? It is another fake lens company. Lens is probably made by Samyang. Company address is mailbox.

    • El Aura

      After releasing its 14 mm f/2.8, Samyang’s next extreme WA lens is a 15 mm f/2.4, sure.

    • The Korean link may as well be to Samyang.

    • Ievgen Nedrygailov

      So maybe you know the difference between “fluorescence” and “phosphorescence”? Could you please explain it here? Because I with my PhD in chemistry is confused by your comment?

      • longzoom


      • J.Coi

        Phosphorescence continue after end of excitation. Fluorescence do not.

        • Ievgen Nedrygailov

          Excellent! So do you really believe that you are the only one person in this world who knows this? Or do you believe that only one of these phenomena can be used to paint something on the lens body?

          • J.Coi

            You are very polite. Thank you.

          • FountainHead

            Apparently people with PhDs in Chemistry neither know it nor know how to google it.

          • Ievgen Nedrygailov

            People with PhDs in chemistry know how to “goggles” in the lab, which is more important than the ability to “google” while sitting on the couch at home.

          • Seeker

            PhD in TROLLING you mean…..

          • Sebastian

            That mistake caught my eye, too. But it’s common for companies to employ some writer that may not get the technical details right. Doesn’t seem like a reason to worry.

          • ThreeRing

            Technical writers and ad writers do tend to have to submit their proposed copy to management, though.
            Doesn’t look professional if they can’t get their first correspondence with the public correct.

  • El Aura


    • Zos Xavius

      What is?

      • El Aura

        I accidentally posted my post as a reply to the article instead of to J.Coi. I corrected that by deleting that misplaced post and reposted it at the correct location.

  • longzoom

    What is a strange love to fly over and rain on the parade? Nobody has seen the lens but knows it is a copy of this and stolen from that… Come on, gentlemen, let us see a first formal test… It is made for us, we should show some mercy…

  • Ievgen Nedrygailov

    I like people commenting on this post. They have not seen the photo examples from the lens, they did not hold the lens in hands, but they already do not like it. The reason probably is in that sign “Made in Korea” on the lens?

    • sophia

      i’m wondering why do you think like that?

      • Ievgen Nedrygailov

        Do you have any other idea why the lens from the new manufacturer which was only announced (no sample photos, no price, no reviews published yet) received so many negative comments?

        • Seeker

          experience in the past….

          • Zos Xavius

            So you have owned Irix lenses before? Good to know.

            Writing something off just because it was made in Korea seems a bit short sighted.

          • Ievgen Nedrygailov

            For us, regular people, the lens is just announced. At the same time you have already had an experience in the past. Traveling in time? Here is one more tip for you. Next time you can say that you have bad feeling, it always works. Any time when something new is announced write a comment “Men, I am not sure about this product. Have some bad feeling.” Very soon people will consider you as the most experienced person in the photo community.

  • Michael Sullivan

    they are clearly going after astro photographers. It will be a premium product, not a “budget” item at all. And I expect it will excel at capturing the milky way wide open. Note the 1/3 stop improvement over all other 14mm FF lenses. Heck, I might even add it to my list of “must haves” if it performs well wide open.

    • nwcs

      I think more general landscape than anything. For astro-landscape photogs the coma and CA characteristics are going to be very important and if they aren’t well controlled then no one would use it for that purpose. Although I could see people using it for aurora pics.

  • CHD

    Looks awesome

  • harvey

    want it – my IR capability just got wider.

  • Seeker

    i get excited whe i see real image samples.

    all they have shown so far are small images…. wonder why.

  • TinusVerdino

    Dollar prices don’t include tax, so $500 for the firefly and $650 for the blackstone.

    • Ethan

      Oregon has no sales tax 🙂

      • TinusVerdino

        Ok I will move there. I did some reading, I am white so it should be ok :p

  • Flodder

    has anyone seen a real lens yet?

    or just renderings?

  • fanboy fagz

    this lens looks promising. according to its spec sheet at least. looks like a nice. lens. hope it gives zeiss and samyang/rokinon some competition. who knows how good it will be, wait and see

  • Duncan Dimanche

    that’s a very good price ! If of course it performs as well as it says it does. I would get the firefly version probably
