  • 12-40 Pro - noisy during AF?

    Hi. Has anyone heard of a 12-40 lens making a quite audible blowing, puffy, airy noise during autofocus? The sound goes away when in MF mode, and also seems to manifest on some bodies but not others. (When other lenses are used on the body in question the noise doesn't happen).

    No, used with EM-1 and MK II. I am a bit on the deaf side though!

        I’ve never experienced that with that lens, nor with any other lens using my EM-1 ii.

        If it’s still under warranty then contact Olympus. Even if the warranty has expired contact them anyway as if they’re aware of a manufacturing defect then they *might* have a “soft recall” in place (= free warranty extension for that problem, but not publicised).

        There are various weather seals internally and your sounds suggest a fault with one or more of them.
        Pentax K5ii, 2 x Olympus OM-D E-M1 mk2 (one with HLD-9 battery grip), Oly Tough TG-5, Ricoh WG-4, Canon Digital IXUS105 plus underwater housing.
        Pentax 18-135WR, Pentax DA* 200mm f/2.8, Sigma 8-16mm (K-AF mount)
        All three Olympus f/2.8PRO zooms plus MC-14 1.4x teleconverter).

        Plus various 35mm OM bodies/lenses, Oly 35RC rangefinder, and half-frame PEN-FT body plus various lenses. MTO-11MC 1000mm f/10

            Not noticed anything untoward on my 12-40 and I've got very sensitive hearing.

              Not with mine and never read about it before FWIW.
