Irix 11mm f/4 lens quick hands-on first impressions

Gaël Vacher (website | 500px) was able to try the new Irix 11mm Blackstone lens (Nikon mount) at the "Salon de la Photo" show in Paris a few weeks ago. Here are his quick hands-on first impressions:

  • The lens is pretty sharp wide opened but with a lot of lateral aberrations on the edge of the frame at any aperture.
  • Distortion seems minimal, vignetting is clearly visible wide opened and it doesn't really disappear even at f/11.
  • Handling is great, on par with Irix 15mm.
  • I was told that the new Irix 11mm lens will be available in January 2017.
  • I didn't have much time but I took a few photos with my Nikon D600. I have attached 2 full sized samples at f/4 et f/8 (opened in LR, jpeg export from Raw files, exposure adjusted, no sharpening and no noise, vignetting or chromatic aberration reduction applied):

    This lens would be ideally matched with a high-resolution Nikon F-mount FX that supports image magnify and focus peaking, electronic first curtain, electronic level indicators and articulating touchscreen.

    • yes, more of a “quick hands-on first impressions”

      Why? With lens this wide you almost don’t need to focus at all because everything is in focus and it is certainly not susceptible to shake caused by the shutter … you hardly need a viewfinder … you just point to some general direction and shoot …

        The main purpose of viewfinder when shooting with such lens is to make sure your feet are not in the picture frame. 😉

        Really? If you have this lens, there is almost no need to focus at all because everything is in focus … and that this lens is not susceptible to shutter shake …. and there is no need for a viewfinder?

        If you are serious, I can only attribute the difference in our views to my having a diametrically opposed shot discipline.

        I understand the principle of hyperfocal distance but have observed is that the higher the sensor resolution is, the greater the need for accurate focus. There is a reason why even a lens such as this Irix 11mm f/4 has a focus ring.

    love that there are so many great options today outside of nikon.

    the irix 15mm looks lovely. samyang also makes a great 14mm.

    • Jeffry De Meyer

      Samyang makes an okayish 14mm

    Moral of the story: don’t let any human stand anywhere in the frame, this lens mercilessly dehumanize them.

      Centrally located should be fine. Anything outside of the center rule of thirds box is a no-no. And try to keep the camera level…

    The “salon de la photo”, I went there the first year I was assistant photographer back in 1989
    There was not much new to see that year.

  • Even in these shots, there’s a lot not to like about this lens. I am disappoint.

    • Vaggelis Atropus

      not even , but from these photos. you would say even if these were really good shots.
