    I am using them for auto focus with Canon EF lenses to make them work with auto focus and IS on your Olympus or Panasonic.I haven't used them with non auto-focus lenses. There is also a .64X version ,which is about the same. Fits different models. there a lot of variables but you can adapt a lot of lenses and maintain IS,and auto-focus some of the time. But sometimes auto-focus is slow or lens and Metabones won't attach easily.

    I have one for Olympus OM System 35mm film lenses. Works great!

    I use it most with the OM 55mm ƒ1.2, which gives me 39mm ƒ0.85, my "bokeh monster!"
       OMZ 21/2 * 0.7    15mm    f/1.4    1/250s    ISO 1000

    I also often use it with the OM 21mm ƒ2, which yields 15mm ƒ1.4, and the OM 90mm ƒ2 Macro, which becomes 64mm ƒ1.4. Haven't really tried it with longer lenses.

    I also have the much cheaper Kipon Baveyes Ultra 0.7x, which is acceptable if you're going for lots of bokeh and really only need the centre sharp, but it totally disappoints when pixel-peeping the corners. _a005186--.

    I also had the Fotga that cost about $60. Utter garbage. Save your money, and smear some Vasoline™ on and old filter. s4160071-.

    I sent it back, and Shamazon never returned my money, because it was a third-party sale, not sold directly through them, and their policy is no refunds until the third-party notifies them it's been returned. I didn't even realize it was a third-party purchase! That was my last ever Shamazon purchase.

    Plenty of threads here in this subforum on the Metabones SpeedBooster - for example;

    Metabones Nikon to m4/3 speedbooster!

    I had both the Nikon F and Contax/Yashica SpeedBoosters for m43 back in the day - best way to use old film era lenses in my opinion. I have now gone to Fujifilm and again I am using the Metabones Speedbooster Contax/Yashica. Heaps of m42 glass available (which can easily be adapted to the cy mount), bang for buck value in the Tamron Adaptall series of lenses, along with plenty of awesome Yashica ML and finally at the top of the class - Contax Zeiss glass.
