New Lensbaby 5.8mm f/3.5 circular fisheye lens announced

Lensbaby announced a new 5.8mm circular fisheye lens available for Nikon and Canon mount:


This Circular Fisheye lens is great for capturing the scale of endless landscapes and big events, fun self-portraits, quirky shots of pets or friends, creating extreme perspective, and experimenting with unique lens flare.  It is capable of capturing a 185° angle of view and focusing from 1/4 inch in front of the lens to infinity. That extreme close-focus paired with the incredibly wide 5.8mm focal length produces other-worldly distortion with exceptional sharpness throughout.

The Circular Fisheye is optimized for APS-C sensor DSLRs, while producing a smaller image circle on full frame DSLRs.

  • This is an interesting new direction for Lensbaby.

  • Spy Black

    Good thing it brings a user guide…

    • AM I Am

      But the user guide is limited to one-year warranty.

  • Eric Calabros

    they should name it MEF (Make Everything Funny) lens

  • Daniel

    “Polished internal barrel” – a good way to ruin every photo

  • Duncan Dimanche

    ….ummmm nope not for me…
    a 14mm samyang does pretty much the “same” but without the vigneting…

    • Mike M

      The 8mm Samyang/Bower/whoever fish might be in the same league, but the 14mm certainly isn’t, it’s image quality trounces this but even on full frame it’s only got 115 degree view vs 185 for this lens.

  • Really?

    “The Circular Fisheye is optimized for APS-C sensor DSLRs, while producing a smaller image circle on full frame DSLRs.”
    And how does it manage that!!??
    Hopefully the other info is more aacurate.

    • AM I Am

      Manage what? Your lack of comprehension?

      • Cheeses.

        We’ve had DX for how many years now?
        And still people like you don’t understand that it’s just a crop.

    • Mike M

      I’m pretty sure they mean it still creates the same size circle, which relative to a full frame sensor, is an even smaller portion of the frame. It’s pretty poorly worded, so I’m not sure the critical reply was that justified from the other poster, but it should be pretty obvious by the same rate.

      • Garfield

        The OP is totally correct and justified.
        You don’t think that maufacturers info should be accurate then.?
        Presumably you were happy that Sigma told us for a while that the repro ratios of their 1:1 macros were 1:1.5 on dx bodies. That was nonsense too.

  • Mike M

    Artistic effect aside, it seems like the 8mm Bower/Rokinon/et al lens is a much better value at 50-100 less and without all the flare and reflections.

  • Thylmuc

    The polished barrel apparently is intended to produce an additional, ring shaped “image” around the real image. Not sure if it has so much of an effect on the image quality as such. Could probably be eliminated in Photoshop, if unwanted.

  • TinusVerdino

    So were these samples made with aps-c or FF? Looks like to be about right for the Nikon 1.

  • Kynikos

    Would be more interested if I could get an unpolished barrel. Novelty of polished would get old very quickly.
