  • E-mount and MFT seems to be getting lots of new adapters, as opposed to only e-mount. (Which is nice)

  • what ? ....only 19 cents more for the focal reducer ?

  • @kurth

    Very generous.

    Had this been Apple it had been 100% more for simple one, as it looks more streamlined and premium without glass.

  • ...and it's about $80 more expensive than their ef to e mount version ...go figure ? Let's see if the electronics work any better !

  • Optics are worse than my Zhongyi Lens Turbo II. electronics do not work for my a6500 and my tamron 28-75 and vintage sigma 28mm 1.8 lens. No AF, No Iris control. Any experiences with the a6500 or a6300?

  • @Vitaliy_Kiselev Will these speedboster available via deals? Very interesting in m43 speedbooster, hope see some test vs metabones and kipon

  • any news? Need cheap speedbooster for gh5+18-35 with autofocus

  • @Readbook

    They had been on sale already, at least I remember posting deals. Not PV deals, I mean in shops.

  • @vitaliy_Kiselev are you sure? I don't see it in deals june-august. I contact with one seller on ali, they said that cannot ship this item now. And I don't see any review on youtube.

  • any news for ef-m2? (m43 version). Still not sale anywhere, no one feedback from user

  • Well, I see orders on top aliexpress link.

  • orders yes, but no one left feedback. I think this buster did not exist at this time

  • I've been using the non-optical version the EF-M1 for a few weeks with manual (non-electronic glass). Also use Metabones XL focal reducer, and picked up this Viltrox for when I want to use EF glass without focal-reduction. Finally got around to trying it with some AF/OS lenses and having issues. OS does not work on OS EF lenses - GH5 stabilizer says it's on, but showing no effect with OS EF lenses. Aperture values are incorrect. Can see in this video here (on computer screen):

    that there are recent firmware updates for this exact model, but Viltrox website seems to be down and can't find any mirrors to the firmware. Considering returning it. A review just popped up on Amazon from another user who seems to be having same issues. Sure it could be resolved with a firmware, just cannot actually connect to site to get new firmware to test.
