    Huge. Is this for dslr or mirrorless? (the 45 1.4)

    • DSLR

      • TinusVerdino

        82mm filter thread, only 4 less than the new Sigma 85 1.4 art. The tamron 45 1.8 with AF and VC has 67mm. Samyang 50 1.4 77mm. Pentax FA 50mm 1.4 49mm. It is too big. Maybe for shooting on a tripod with a 5dsr, but no sane photographer would use this as a walkaround.

    • I think all of their lenses are for DSLR – that’s why they now introduce an adapter for mirrorless.

      May be this lens uses a retrofocus optical formula like Zeiss Otus Apo Distagon T* 55mm f/1.4 ZE/ZF.2.

  • TinusVerdino

    The Formula was co-developed with Zeiss in the early sixties, but it is still a very good lens. On full frame it will do better than aps-c as it was designed for that. If you wand boring perfection just stop down a bit, it will deliver just as well as most modern 50’s.

    • Why should it be any better on 36MP FF when the 10MP APS-C sensor is basically just a center crop of a much lower pixel density (~23MP) FF sensor? That, and the Pentax was just another of the “classic” Double Gauss lenses (a 7/6 I believe). Nobody denies that they’re all pretty good at f/5.6 but at f/1.4… not so much. Even if the corners would recover magically on FF (but why would they), you’d still be left with a huge midzone deep. Photozone also cites low contrast.

      • TinusVerdino

        The pixel density of FF 36mp is the same as 15mp aps-c. Not so much difference. Low contrast wide open is a characteristic of the design, it is good for portraits. E-photozine have tested it on the K-1 and it performed well. Sure there is a sharpness and lateral chromatic aberrations trade off with bigger more expensive designs, but is is cheaper, light and compact and you can shoot great pictures with it. https://www.ephotozine.com/article/smc-pentax-fa-50mm-f-1-4-review-29443
