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
  • Clickless Ring Can Convert to Clicked
  • 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.Micro Four Thirds speed boosters are shipped with a clickless ring that can be easily converted to a clicked ring without additional parts.

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.

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

        The Metabones Speedbooster for Micro Four Thirds camera (Nikon G F Mount) is a must have if your using Nikon glass. It gives you increased F stop and wider field of view. I'm using this with as Panasonic Af100 and GH4.

            I use the SpeedBooster to link Nikon Glass to my GH3 and it does the job but doesn't allow for auto-focus which kind of blows when Im using my 80-200mm and trying to set the shot as quickly as possible. I havent had shots ruined because of this fact but it is something that I would like to see developed in the future .

                  I have no issue with this speedbooster. This is my second one and this time its for my gh4. Wish it was cheaper but its all good. Makes your 2.8 lens even faster and wider. Plain n simple.

                    I use it on my gh4, and its been great so far. The apeture ring doesn't click, its very smooth, perfect for video. I just wish it was an active adapter, and supported EF so i can remotely focus using the wifi when mounted on a drone or camera stabilizer.

                      I got this to use with some legacy Nikon lenses on my GH4, and it works great! I like that you have the choice of using the aperture ring on the lens or the ring on the Speed Booster. Wish that Metabones included instructions, but I emailed the company and some days later received the following (Have no idea how he knew my nickname...):

                      "Hi T,

                      Sorry! We have not manual or instruction for all adapter and speed booster now.

                      Are you have problem on use?

                      For the aperture adjust, if you use a Nikon F Lens, you need set your Lens aperture to full close when use the adapter ring to control iris,
                      other wise, set the adapter ring to "7" when use Lens ring to control iris.

                      Thank you!

                          I have purchased 3 different adapters for my Nikon lenses to use with my AF-100 and GH4, this is the only one I will continue to use. Yes it was more money however, the other 2, one was too tight, and the other too loose.

                                "What a hunk of junk!" That's what Luke Skywalker said about the Millennium Falcon. Well, if he saw a Metabones Speed Booster, he wouldn't have said that. Not only does she have it where it counts kid, it looks and feels great. This will change your life the way a toaster changed bread. The way the Big Wheel gave kids their first transportation. This thing is rock solid. The glass is like buttah. You've seen the rest, get the best. I've held $ in my hand, and I gladly exchanged it for this Speed Booster. Look, if you have a need for a product like this, quit reading and start adding it to your cart. It's the best thing you can put between your camera and your lens.

                                  Not only does it make your adapted lenses faster, but it can actually be adjusted for backfocus to collimate your adapted lenses on any m43 camera body. Also features the best mechanical aperture ring/lever design of any comparable adapter.

                                  After intense research, I bought this for my brand new GH4. Let me put it this way. If you are going to use your GH4 for video, you MUST have this. This adaptor changes the game. Paired with a fast lense.. this adaptor will give you the shallow depth of field we all are trying to achieve. It is solid. fits tight. Produces great images. It adds aperture ring to your lens. This is awesome for film makers. You do not have to turn a dial on your camera to adjust your iris. Once purchased.. you will have the urge to buy fast zoom lenses. Those Nikons are wide. So you will not be able to set your camera on your tripod. Thank God, Metabones comes with a tripod mount.

                                  I really never cared for teleconverters so I figured this would be about the same deal (in reverse :) ) ... nice to have when you really need a larger sensor look and "less" focal length

                                  Well I was totally wrong, love this thing n my GH4 for video. I don't think its been off the camera more than twice in the 3 weeks I have owed the little Panasonic. The Metabones is built really solid and the ring to change the aperture has a nice even drag to it (fluid head like) so even if you have lenses with aperture rings use the Metabones ring its much better than clicking through the stops

                                  Sharp and contrasty with Tokina 12-24, Nikon 50 1.4, 85 1.4, and 400 2.8, I never expected it to look as good as it does really glad I spent the money.

                                    I use this with Nikon lenses on my Panasonic GH4
                                    There are no reviews that dont regard this as anything but the greatest adapter.Just go online and read review after review.I almost bought the cheaper Photodiox adapter-So glad that I spent the extra cash and got this.
                                    I can now use all my Nikon lenses and enjoy extra light!!Obviously one cannot autofocus, but with Peaking on the GH4,manual focus is easy.It has an aperture ring on the adapter to increase or decrease aperture!

                                          I'm using this product to adapt Nikon lenses for use with the MFT's Panasonic GH3. The Speed Booster is well made and meets all my expectations. I would have given 5 stars, but there is a slight amount of play between the SB and the GH3 body. Not the same "locked in" fit as with a lens attaching to the body. Others who I know use the Speed Booster report the same fit. Does not affect function however.

                                            Works as intended, solid construction, good quality optics - allows me to use my set of Nikkor glass on a GH4 - works will all my AI, AIS, AF-D and G lenses. Built very well and the detachable 1/4 20 shoe is very helpful when working with larger lenses on the camera. One drawback is that it will not work with electronic aperture lenses such as the 45mm PC-E lens.

                                              I cannot say it better than anybody else. This is an amazing product and definitely worth the investment if you already own Nikon lenses and want to continue using them. There are many reviews out there on this speedbooster, and I recommend looking into those before you decide on which one you want to get. By this, I mean the BMCC and BMPCC versions for M4/3. They perform better, but can damage your camera if not used properly.Anyway, I am completely happy with my choice, and I will continue to have this in my kit. Allowing a wider viewing angle AND gaining an extra stop?! Obvious choice.

                                                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!

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

                                                  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.

                                                  • Was this a gift?:
