How to use with modern cameras?

Lenses with mounting thread M42 (M42 X 1 / 45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this it is enough to choose the right adapter (adapter). You do not need to carry out any additional steps to modify the lens.

The cheapest adapters can be found aliexpress.com... There are adapters (adapters) with a chip that provide more convenience during shooting, usually chips are used to confirm focus and / or metering exposure, and form the correct EXIF. The chip does not affect the image quality in any way.

For some SLR cameras (for example, Nikon F) it is necessary to use adapters with a corrective lens, which allows correct focusing at all focusing distances. For any mirrorless camera, such a lens is not needed, and the adapter is a simple decorated hollow metal tube with an appropriate mount.

  • UstasFritZZZ

    From the old 135 / 2.8 I really like the Canon FD version. I tried different ones, but Canon has the most contrasting picture, high sharpness, minimum artifacts + built-in hood as a bonus.

    • Nicholas

      Probably a good lens, though it seems to fit only on the BZK. Painfully, he has a small working segment.

      • Andrei

        Regular M42. What is the problem?

  • Michael

    As far as I have heard, to make a bad 135 is still to try.

  • Albert

    I have such happiness under the brand "HANIMEX"

  • TSerg

    Hanimex 135f / 2.8 Tele-Auto only with a large aluminum ring with diaphragms. Knowing this for a long time, but on the float, even after the development of the first emerging coils, selling, do not get lost. Korean shirvzhitok eri pochatku ob'єktivobuduvannya in the tsiy krainі. I would like to write a lot, how Hanimexi robbed at Nimechchina for the Australian market, for the whole of the German. 135-ki is important to kill nasty, as to write optics, albeit know-it-name as times such and were prepared.
    Problems with the sharpness, contrast and HA, like in Hanimex, and in the same ALFO. This is more beautiful to go around the side, afraid of the way in the middle of them lightly trap.
