Product Highlights
  • Fits Nikon G & F Lens to MFT Mount Camera
  • Increases Maximum Aperture by 1 f/Stop
  • Increases Angle of View by 0.71x
  • Built-in Aperture Control Ring
  • Wide-Open Button
  • Detachable Tripod Foot

The Nikon G & F Lens to Micro Four Thirds Mount Camera Speed Booster from Metabones allows a full frame Nikon G & F lens to be mounted to a Micro Four Thirds mount camera and in doing so, increases the angle of view and increases the maximum aperture one f/stop.

When a lens intended for full frame sensors or 35mm film is mounted to a camera with an Micro Four Thirds sized sensor, it transmits a larger area of light than the smaller sensor was built to accept and therefore the angle of view of the lens decreases and the equivalent focal length increases. The Speed Booster condenses light from the lens and projects it onto the smaller sensor allowing the sensor to utilize all of the lens' light and effectively produce a full-frame angle of view with an MFT sensor. A corresponding increase in the maximum aperture of one f/stop makes the lens more effective in low-light situations and able to create a shallow depth of field. 

Metabones Speed Boosters are quality made, using precision-machined brass with chromium plating on both the camera-body and the lens sides of the booster in order to ensure smooth mounting, quality aesthetic, and durability. This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.

Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster. Nikon G and F lenses including non-AI & AI lens mounts are compatible. The Nikkor 2.1cm f/4 and 20mm f/2.8 AI-S lenses are not compatible with the speed booster. 

Allows a full frame Nikon G & F lens to be mounted to a Micro Four Thirds mount camera and in doing so, increases the angle of view and increases the maximum aperture one f/stop.
Both camera-side and lens-side of the speed booster are made of brass, precision-machined and plated with chromium.
Precise fit and solid connection - lens has no play, gap or wiggling when mounted on speed booster and no adjustments are required to fit your lens.
The Speed Booster uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
The lens' aperture is set to wide open for ease of focusing while the Wide-Open (WO) button of the Metabones Speed Booster is depressed. Release the button and the lens will return to the aperture set on the camera. This wide-open function is automatically shut off when you actually take a picture and during movie capture.
This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster.

        I could not be happier with this neat devise. It works as advertised. All my very expensive Nikon glass can be used with my GH4 thanks to Metabones. The speed bump increase is just more icing on the cake. Thanks B&H for getting it to me so fast!

          Shooting indoors or in low light situations where you need an extra f stop while at the same time wanting to reduce the 2X crop factor inherent with micro four thirds camera sensors? If so, this product is a great addition to your creativity toolkit.

          The adapter is solidly constructed and precisely machined. It fits perfectly into the Panasonic Lumix DMC-GH4. No wiggle.

          Simply set your lens to the smallest aperture (highest f stop) and then use the Speed Booster adjustment ring to smoothly and precisely adjust the aperture.

            This one little device allows my entire stable of lenses to not only be used on my GH4, but prosper! The Sigma 35 1.4 is like a dream with 4k! Buttery smooth out of focus and tack sharp where you want it! The aperture is smooth and stepless and the extra stop of light is just icing on the cake! To me, this is a must have for your GH4 or any M43 camera. Highly recommended!

            Comments about Metabones Nikon G & F Lens to Micro Four Thirds Mount Camera Speed Booster:

            I use the Metabones Speedbooster to attach my Nikon lenses to my M4/3 cameras for video. Adding a full stop is greatly beneficial in low light, and reducing the crop factor is extremely helpful. Together with the standard Novoflex Nikon to 4/3 adapter, it's as if I've doubled the number of primes I have in my bag. Amazing tool.
            The one negative I have is that the connection to both the camera, and especially the lens, is very tight, and makes it difficult to change lenses easily.

                I bought this to use with the Panasonic GH3 for video primarily. It does what it says it does. One thing of note is that the tripod mount on the bottom does not align level with the bottom of the camera, so when mounting it to a tripod the camera is not level. You don't have to use that tripod mount, but it would be nice when using heavier lenses. It loses one point for that (unless there is a way to adjust this)

                  This product is fantastic for film makers. The only complaint is the aperture ring is a little close to the lens mount, making it difficult to adjust on the fly, but that isn't a big issue for me. Overall it works beautifully with the Sigma 18-35 for APS-C cameras. I'd highly recommend it.

                  Super 35mm field of view, another stop of light gathering, declicked aperture control, rock solid construction. Breath new life into your nikon-mount lenses. Using with Rokinon 35mm T1.5, Nikkor 55mm F1.2 SC, Tamron 28-75mm F2.8. All work splendidly! I hardly touch my m4/3 native lenses any more! Highly recommend!

                    Comments about Metabones Nikon G & F Lens to Micro Four Thirds Mount Camera Speed Booster:

                    Wow, this thing in a wonder! I purchased it as an accessory for my AF100A because I was interested in using Nikon glass. I heard about this speed booster and what it could do and I was extremely intrigued! Not only does it adapt Nikon lenses to the m4/3 camera, but it also increases the field of view significantly! You can control the aperture from the mount, which I prefer over using the camera's iris control (don't like that knob on the AF). The biggest draw, however, is the increase in aperture. I purchased this with a Nikon 50mm f1.8 and get a 71mm field of view with a noticeable increase in the brightness when opened all the way! I've used a f0.95 lens before and the brightness is pretty much identical! This f1.8 50 is not a f0.9 71! HELLOOOOOO shallow depth of field! I wasn't sure how well it'd work, just reading about it sounded good but how could it actually produce those results? After purchasing it I see now that it's all true! Glad I made this decision!

                    Used my photographer friend's f2.8 70-200 (and his 24-70 2.8) lens and MAN did it get bright! I know a stop above is 2.0, but it almost looked like it went up to 1.4! My friend said he had never seen an image get that bright on that lens before! I don't know how they did it, but they did! Nice work, Metabones!

                    I primarily shoot on a Panasonic GH3 and the Blackmagic Pocket Cinema Camera. The ability to use Nikon DX and larger format glass to achieve wider sharper shots than a dummy adapter can provide is awesome. I have the regular and pocket editions of the speed booster and am thrilled with both. By having a standard non-boosting Nikon G to M4/3 adapter as well I can now achieve three different focal lengths with the same glass on the BMPCC and 2 focal lengths on the GH3. I also like the fact that the adapter essentially covers the otherwise exposed sensor of these mirrorless cameras. I have seen no degradation of image quality - actually my 50mm 1.4 looks noticeably sharper! And with the Tokina 11-16 I can finally get respectably wide shots on either camera. The aperture control is smooth and easy to adjust while shooting. The only thing that could make this adapter better is if Metabones drops the price.

                          Loving it so far. I'm using it with GX7 and mounting several lenses from my old Nikon D40X.

                          The excellent focus peaking on the GX7 means that the manual focus limitation doesn't really cause issues for me.

                          The two Nikon mount lenses that seem to be most interesting from my kit are:
                          - Nikkor 50mm 1.8D - the speed booster seems to be giving me sharper images without going to f4 with this lens as I used to have to do with the Nikon. The contrast also seems to be better.

                          - Tamron 70-300 with Macro - makes the whole thing very heavy and it is almost impossible to take pictures without a tripod but again...

It turns the GH3 into a better low light video machine than the 5d3 (turns an f 1.8 into an f 1.2; 2.8 into 2.0, etc), with sharper picture, reduced crop factor (2x into 1.4x) and opens up a huge variety of Nikon lens options. The GH3 shoots higher bitrate video than the Canon and the speedbooster also sharpens the image. One small drawback is internal reflection ghosting in rare instances, and color fringing around light sources at the edge of the frame. Small price to pay for everything else. If you shoot micro 43, this is a no-brainer. $[$]for soft video, or $[$]for sharp, high bitrate. Easy choice for me!

                                The speedbooster essentially doubles your quiver of Nikon Lenses in terms of focal length. Sharpness and IQ are superb. Also, you get new wider lenses, and faster. Build is very solid, but I haven't had it long enough to really have a strong opinion about how well it will hold up. I really like that it has an Arca compatable Tripod mount, which is also removable. Also, it's great that the aperture adjustment has a decent amount of throw, unlike typcial G to m43 adapters such as Novaflex and the cheaper Chinese-made variants.

                                Using it mainly with the Sigma 18-35mm on a GH3. Fantastic combo!

                                  I thought about getting one of these ever since they came out, and now that I have it I cannot believe I didn't get one sooner. If you have a MFT camera mount, don't even consider your options, just get it.

                                    This thing is amazing. Not only does it adapt my nikon glass to a MFT mount, but the added stop of light is really something amazing. Not to mention how this thing increases my sensor size. Considering the 2.4x crop on the BMCC, this adapter gives me so much more room to work with my lenses. A great investment for any BMCC user.

                                    Love it so far. Used a couple of my friends Nikon lenses and its awesome. The camera I use is the Panasonic GH3. No negatives about it so far.

                                    Works great & very nicely built, but I received it just as they announced the BMPCC-specific model and decided to return it.But I was torn because the new one is wedded to only one camera, whereas this model can also be used with any MFT camera, yet isn't quite as effective on the BMPCC.
