    They choose to release C/Y and Leica R first before EF?

    How many Canon mount users are out there that just can't wait for this thing on m43, a lot more than C/Y and Leica R shooters I'd guess

  • soundgh2soundgh2

    Oh I dont know :) No Cannon glass here just lts of nice C/Y Zeiss loveliness

  • RRRRRRRR

    c/y before EF any day of the week.

    Besides, EF is NOT easily converted to MFT with electronic control (with focal reducer or not), or there would be a bunch of options already.

    Has anybody used a speed booster with a GH camera or other M43 for video? All I've found so far is from the Sony NEX series.

  • Vitaliy_KiselevVitaliy_Kiselev

    @JAY_T

    m43 version is not available yet.

    On the Metabones website they are currently selling two M43 Speedboosters, and have been for weeks.

    @JAY_T

    Also Philip Bloom tested the currently selling M43 Speedboosters on the BMCC MFT. Vitaliy posted it earlier in this thread.

    Yep, sorry, I meant common mounts, I just fully forgot about their weird approach.

  • JAY_TJAY_T

    Ya, the CY to M43 and Leica R to M43 boosters. I couldn't find any vids at all. I did see Bloom's but I'm more interested in how it looks with the pannys. Cheers guys.

    Is there any information from that guy @Brian202020 ?, i really want to build something similar, with a 0.5x focal reducer, making any FF lens adapted to m43 while keeping the focal length, i am planning in buying the same focal reducer and build something similar, i am not a serious photographer, but i like to play with lenses so quality is not an issue, also i have a Olympus OM 55mm F1.2 i would like use, it is very soft already so maybe mantaining the focal length will keep the softness away, i don´t know...

  • RRRRRRRR

    c/y-m43 speedbooster is, in short, awesome. I got mine last week and I´m considering getting another one. Well worth the money.

    It really makes the lenses pop as the zeiss full frame glass looks so much better on a slightly bigger sensor (than m43). Until now, I´ve hesitated to use anything but the 28 f2 and 60 macro on my gh2´s.

  • nomadnomad

    @RRRR Thanks for posting! Did you observe anything negative regarding background? Some of my Contax Zeiss have such beautiful bokeh, I wouldn't like to ruin that. Sitting on the fence for the Speedbooster…

  • RRRRRRRR

    @nomad

    Absolutely nothing, so far.. (quite the contrary as I´ve observed) I could maybe make a somewhat comprehensive (stills) test with all my c/y glass.

  • nomadnomad

    Well, if you publish a few of the wider ones for the forum, it should suffice.

    Thanks anyway!

  • vicharrisvicharris

    That would be great.

  • nomadnomad

    Thank you!

    Obviously, it doesn't ruin anything. The 28mm has a bit nervous bokeh sometimes without it too, and the f…ing beautiful bokeh of the 60mm isn't harmed at all.

    Good to know.

  • RRRRRRRR

    absolutely.. I find in particular the 85mm to improve a whole lot with the SB. Aberrations are much less noticeable, and that is true for the whole range of lenses as far as I´ve observed. Coma is also a lot more under control wide open.

  • RRRRRRRR

    Here are shots with the 28mm f2.

    The lens is set to the same aperture, although the actual T stop obviously is different. I tried to aim for the yellow sign for far focus (I may have set it elsewhere for some of the first shots) and I tried to keep a distance of approximately 1 meter to the focal point for the near focus shots.

    quick question will the EF version of Metabones work with crop lenses like the new Sigma 18-35mm 1.8 or is it only meant to work with FF lenses.

  • MeierhansMeierhans

    It depends on the image circle of the specific lens. I checked the Sigma and it should work. Actually it was right at the border.. so it might vignette a tiny bit at 18.
