  • LoliFromFutanari

    If there were DSLR mounts on the list, it would be an ideal offer for an even larger circle of photographers.
    If camera manufacturers decide to drop support for DSLRs, it would be very nice for alternative manufacturers to release lenses for many systems.

    • Konstantin

      DSLRs are dead, it is unprofitable to produce separate optical circuits for them. Forget about them already and switch to mirrorless ones.

      • Andrei

        I support it, especially since it’s more difficult for DSLRs to release optics like on a bzk. Yes, and in manual mode, focusing on sharpness is much more convenient

      • LoliFromFutanari

        If mirrorless cameras with autofocus at the level of at least amateur DSLRs were as affordable as the same amateur DSLRs from 2009-2011, then yes, no doubt, this would be a good solution.

        • Viktre

          Are they unavailable? A6000, M3/M6, a bunch of different micros?
          Yes, and to focus on a very small percentage of those who live not even yesterday - the day before yesterday, the manufacturers are definitely out of their hands. The vast majority of users in the world will simply go to the store and buy the current model.

        • Dmitry

          If someone has enough money only for a used mirror from 2011, he will not buy new lenses and there is no point in releasing them

  • Dmitriy

    Hi all. I did not find where to write. I have a nex f3 with a whale lens on my hands. I feel that this setup limits me or something. There are thoughts to buy a fast lens or better to change the camera. And indeed, the camera was bought for 5k, for which you can change my setup so that it is not 6 times more expensive, but at least 3. Thank you!

    • B. R. P.

      First, it's better to write something like this here: Secondly, specify what exactly you do not like in your setup. Often, people with such questions tend to change the awl for soap, if there is no clear idea of ​​​​what is required.

      • Dmitriy

        Hello! Thanks for the answer. After reading your question, I could not answer it. Indeed, I may be in a hurry. I will not change anything, except thinking. I was not happy with the fact that I had to increase the shutter speed / ISO constantly. I will buy a fast lens and will continue to use it, but analyzing it more strongly.

        • B. R. P.

          Please, good health. I think you made the right decision. Keep in mind that with a fast lens, you still have to hide a little sometimes.

  • Igor

    Mirrors are not dead, it’s just marketing so that the conveyor doesn’t stop, and a smart person won’t give up a mirror completely. You can buy one mirrorless camera for a change. playing around has its advantages...

    • Rodion

      In 2024 this sounds naive.
