Comments: 8, on the topic: Announcement: Sigma 20mm 1:2 DG DN C | Contemporary

  • Zheka

    Why are there no comments? Is the lens bad😂😂😂😂

    • Specialist

      Duc just announced, even rich commentators are not ready. You can only snuggle up.

  • Victor

    $700 is pretty big, given the crop size and f/2 maximum aperture, and the cheap 19/2.8 on the aftermarket for a hundred, albeit a stop darker and not waterproof.

    • Arkady Shapoval

      And what's with the crop?

      • Victor

        I made a mistake, it seemed that “DC” was found in the abbreviations%)

        As for a full-frame light width, the price is quite normal.

    • Joe

      > given the crop format
      Sigma 20mm 1:2 DG DN C - full frame.
      > as well as the availability of cheap 19 / 2.8 in the secondary market
      But this one is already incomplete.
      Conclusion: first try to find an analogue of the lens from the announcement, then compare.

    • Zheka

      So that's it. Victor rejected. They won't let you out. This is not an expensive lens, but you probably earn little 😁😁 what secondary market are you talking about

      • Victor

        Zheka, you are not in a hurry, carefully read the entire thread, and not just the first 5 words in the first post))

        Well, we earn a little of course, to be honest, we have to take into account the price / exhaust ratio. And what a strange question about the secondary market, tell us more?)) Yes, I know that the manufacturer is not obliged to focus on it.
