    After selling my Nikon G Speedbooster in order to wait for the EF version, I finally got around to getting another one (the S version that works with OM-D cameras). I only had a single Nikon lens at the time so it didn't make much lens. Now with the EF version, I'm able to use nearly all of my SLR lenses. And I have to say: I'm quite pleased.

    Here are some snap shots from a few of my fast telephotos so far:

    Minolta MC 58mm f/1.2 + SB = 41mm f/.9 (82mm f/1.8 FF-equivalent):

    Nikon 200mm f/2 +SB = 142mm f/1.4 (284mm f/2.8 FF-equivalent);:

    I've done little more than a bit of random shooting and I'm looking forward to getting out and doing more than snap shots. Still, I'm extremely pleased.

    The Nikon was never really useable on μ43 and now it looks pretty nice, though still not up to the level of quality on my A7. I'm especially happy with the Canon FD 135mm f/2. It looks awesome wide open (though focusing is hard). For those wondering...all my FD lenses were converted to EF mount back when I had my 5d, that's how I'm using them now on the EF speedbooster. The Minolta looks excellent, too. Definitely less CA & spherical aberration than it has on a regular adapter. The only downside is that with a lens like that, that's already super fast, the would-be shutter speed gain between f/1.2 and f/.9 is lost on a digital sensor because of pixel shading.

    The combination of IBIS and an extra stop of light from the SB means that I can shoot my Nikon 200mm f/2 at 1/25 a second and still get a sharp image.

    I shot a similar photograph to this one with the Canon FD 85mm f/1.2L on my A7 about a year ago. Now, I've redone it with the same lens with the MB Speedbooster.

    I know that most people think narrow DOF when they hear speedbooster, but here are two shots with the Canon FDn 85L stopped down:

    I'm enjoying these snaps. I've just picked up two FD lenses and a MD mount lens (regular adapters are in transit as we speak). I like the idea of a m4/3 body + focal reducer along side something like the a7.

    Each lens can then serve multiple focal lengths depending upon what it gets adapted to...I feel a little crazy for thinking this given the great native glass...but something about this idea is very seductive.

    Schneider Curtagon 35/2.8 in exakta mount with an old Minolta E-Adapter to MD mount. On a Metabones Minolta MD Speed Booster. This lens copy is in superb condition and a joy to use.

    Not bad for a fifty-year-old non-macro long telephoto lens wide open at minimum focus distance on 55mm worth of extension tubes.

    Nikon PC Micro-Nikkor 85mm f/2.8D, Speed Booster Ultra
    E-M1, f/4, unshifted, both camera and lens tilted down:
    2015-11-21 18.18.32 E-M1 _B210001.
    2015-11-21 18.18.32 E-M1 _B210001 2. 2015-11-21 18.18.32 E-M1 _B210001 1.
    Artistically uninteresting as it is, this photo nevertheless illustrates why I love both this lens and the E-M1. The lens for the movements and rendering, and the E-M1 because, I can focus the lens close up and at large apertures* quickly and easily without using the pictured HDMI display (not to knock it — cost and convenience aside, the Atomos display is fantastic for critically focusing tilt/shift lenses on a D800).

    And now for something completely different, a stereotypical "effect shot" using the same equipment, wide open, IIRC, and at full tilt:
    2015-09-18 16.43.34 E-M1 _9180287 1.

    * For smaller apertures and/or greater distances, it usually suffices to remember that, for an 85mm lens,
    t ≈ 16/J
    for tilt angle t degrees and "hinge distance" J feet.

    (To prove this, recall that
    J = f/sin t
    for focal length f, and that, for all values of t supported by the lens's tilt mechanism,
    sin t ≈ 2·pi·t/360​
    with an error of less than 1%.)
