    FD-m43 + Nikon G-m43 Speedboosters FTW!

  • MeierhansMeierhans

    If the image quality is compareable to metabones count me in for a nikon --> MFT version. Hope there will be a PV deal once its out.

    The first FD-m43 adapter I bought was from jinfinance aka RJ on eBay. That $25 adapter's still going strong, and when a bearing came loose all it took as an email to RJ to get a small envelope full of teeny bearings from China in about 5 days. I sincerely hope RJ makes an FD-m43 SpeedBooster knockoff, and I'll buy two or three the moment he does. Good seller, solid gear, fair pricing.

    Vtw, they already sold first batch.

    @lolo I prefer deklicking my FDs :)

    the Lock/Open feature of canon fd adapters is useful for a stepless aperture in video, is quite handy if you have to change the aperture while recording, i do hope they implement that

  • oscillianoscillian

    Could someone who speaks Chinese PLEASE tell the manufacturers we need Nikon G to m43/E-mount "Turbo thingy" with mechanical aperture control.

    And while you're at it: tell them all Canon FD adapters don't need the Lock/Open feature! Just copy Ciecio7's design :)

  • fatpigfatpig

    @niGGo: thanks, will do. :)

    and yes, the BMPCC would be the only application. :)

    EDIT: I read it, this was not new to me. But I thought (I assume this was my mistake), that a certain lens between the elements inside the speedbooster could make up for the increased distance. :)

  • hedroxhedrox

    I would also like to know that if it´s possible to make speedboster only as a focal reducer with m4/3 mounts , I would like to use slrmgic cine Aps-H lenses that would make them with speedboster a beautifull 1x crop on GH series

  • sh1ggysh1ggy

    I'd suggest you should read a bit about flange distances.

    http://en.wikipedia.org/wiki/Flange_focal_distance

    What you want is something totally different to the current speed booster design, although I don't know if it's completely impossible or not. There are for example some adapters with optical elements which correct the flange distance from FD to EF. But here we're only talking 2mm.

    Still, it's a stupid idea. The only camera who would benefit from such a design is the BMPCC.

  • arknoxarknox

    Just because it's a blackmagic camera doesn't mean it can defy the laws of physics. Think about what you are asking, take a m4/3 lens designed for a m4/3 mount and stick an extra bit of metal between the mount and lens. Even if possible to get some sort of focus (not likely) the image circle of the lens provides no benefit to a focal reducer so there would be a massive vignette.

    Focal reducers will only work with lenses that are designed for mounts with a substantially larger flange distance than the mount on your camera and that are also designed to cover a larger sensor size than the camera.

  • fatpigfatpig

    Excuse me for not pointing out:

    i was thinking specifically about the BMPCC with its smaller sensor, effectively giving us our GH2 FOV back on that. With the right optical elements this should be possible, don't you think?

  • sh1ggysh1ggy

    First off, M43 lenses are designed to cover M43 sensors - so even if you'd find a way to boost your lenses they'd start to vignette heavily. Second, if you think about it, adapters only work because the lenses you want to adapt have totally different flange distances. That's what adapters are for. They make up for that. But how you're gonna adapt M43 lenses to a M43 mount? You'd have to get inside the body and change the actual mount, which is just plain ridiculous.

  • fatpigfatpig

    well, is it? I thought with the right lens combination you can make up for the distance difference, cant you?

  • sh1ggysh1ggy

    There's no such thing as a M43-to-M43 speed booster. It's impossible.

  • fatpigfatpig

    does anyone know if we buy a m43-to-m43 speedbooster, can we still use adapters to FD,MD,etc. on it?

  • danyyyeldanyyyel

    @Vitaliy it would be nice if they have a Nikon to M43 adapter with aperture control. It would sell a lot as it would be the ideal adapter for the Tokina 11-16 for the M43 panasonic camera and the Blackmagic pocket camera. I also hope we get some review soon about the optical performance and build quality as well. My m43 to nikon adapter wooble a bit. For a $30 adpater I can live with that, for a $ 200 adapter it will make me think 10 times before buying.

    @Flaaandeeers

    I'll let you know.

  • FlaaandeeersFlaaandeeers

    Any words on M43 plans?

  • maxmizermaxmizer

    always the problem of exposure and stabilization without electronics

    @jleo

    I am quite sure that we'll see cheap ProRes-like formats cameras and raw cinema cameras much sooner than people expect. Under cheap here I mean GF and G cameras prices range.

  • jleojleo

    Now we just need KineRaw to come out with a Personal KineMa Camera for $400 :)
