Allowing you to mount a Canon EF lens on a Micro Four Thirds camera body, this Lens Turbo Adapter Mark II from Mitakon Zhongyi is a manual adapter that maintains infinity focus and image quality, and well as increases the maximum aperture and angle of view. Four elements are featured in the adapter's design, including one extra-low dispersion element, which helps to deliver a well-corrected image with edge-to-edge sharpness and illumination. This optical design also condenses the light reaching the sensor in order to gain one effective stop of light and increase the angle of view by 0.726x to somewhat lessen the crop factor of Micro Four Thirds cameras.

In addition to the optical design, this adapter features a durable metal housing along with stainless steel mounts for secure lens-to-adapter and adapter-to-camera connections. As a manual adapter, electronic communication, including aperture control and autofocus, is not supported between the camera and lens.

Q: 1. I recently got this adapter for my GH4 and my Rokinon EF cine lenses. Im happy with the optics but the lens fit so tight in lens turbo. You have to apply a lot of pressure to twist the lens out after the pin is released. Im worried it may be scratching or grinding away the metal mount on my lens. Is this normal or is it possibly a defect with the specific lens turbo that I have?

A: I had the same problem, it gets easier the more you attach and remove lenses. The pin issue might be a good reason to return it, you probably got a bad spring

Q: 2. Will a Canon 10-18mm work with this adaptor & G85?Speifically, wii the lens be usable throughout the whole zoom range?

A: This lens adapter is the best friend of any full manual lens. So if any lens has data contacting pins then it will not fully work on this adapter. In this case, your 10-18 may can't work fully as you lose the aperture control. Recommendation: go with Metabone Speedbooster instead.

Q: 3. Will this work with Zeiss Milvus lenses and a GH5? Thanx!

A: Yes

Q: 4. I dont understand, I have a panasonic gh4 and the manual focus on my canon lenses doesn't even work with this adapter.. please help?

A: Hi,Your Manual Focus needs to be mechanical in order to work with this adaptor. Electronic Manual focus won't work.

Q: 5. Does this work on Blackmagic Cinema Camera 2.5K MFT?

A: Yes it will

Q: 6. Will the Rokinon 12mm ef-m mount cine lens fit on this adapter?

A: No, the lens is not an EF mount lens but an EF-M mount lens. The adapter is designed for EF not EF-S or EF-M lenses.

Q: 7. How much of a full-frame lens's image is CROPPED, when this adapter is used on micro 4/3 camera?

A: As compared to a full frame camera, the MFT sensor is a 2x crop. With this adapter, it lessens that x0.726. So the image is cropped about 1.2 as compared to full frame.

Q: 8. Hello,ive been looking for an option instead of the Metabones speedbooster for my bmpcc,,WILL THIS WORK after i saw alot of bad reviews on about the adapter and the bmpcc,

A: Yes, this adapter will work on the BMPCC.

Q: 9. WILL IT WORK WHIT 18 TO 250 DC 3.5- 6.3, SIGMA LENS?

A: You may mount the Sigma 18-250mm F3.5-6.3 DC Macro OS HSM for Canon EF Mount onto the Mitakon Zhongyi Canon EF Lens to Micro Four Thirds Camera Lens Turbo Adapter Mark II. However, do note that the Mitakon Zhongyi Canon EF Lens to Micro Four Thirds Camera Lens Turbo Adapter Mark II is designed for use with full-frame lenses, so using the Sigma 18-250mm F3.5-6.3 DC Macro OS HSM for Canon EF Mount (which is designed for the smaller APS-C sensor) will have a smaller image circle on your sensor, and may require you to crop in on the image during post-production when using your computer to edit the image. Also note that the Lens Turbo Adapter Mark II is a fully manual adapter, so electronic communication, including aperture control and autofocus, is not supported between the camera and lens. As neither the lens nor the lens adapter have a built-in aperture ring, this means you will not be able to control the aperture of the camera, so you will be stuck with using the lens’ largest aperture when using this adapter with the aforementioned Sigma lens. With the exception of the above issues, yes, you can connect the lens to the adapter and use the setup on a Micro Four Thirds camera.

Q: 10. Will it get the DZO Pictor 20-55 to work on a BMPCC 4k (once the traditional Metabones 0.71 won't work)? I've been using a generic ef-m43 mount adapter but it comes with some issues such as making it really hard to shim the lens and keep it both parfocal and infinity focus... any solution on this issue please?

A: The protrusions on the DZO Pictor 20-55 do make it an issue with many ef to mft speed boosters. Since various manufactures can have varying tolerances in their build and optic placement, we believe you could face an issue using the DZO Pictor 20-55 with the Mitakon Zhongyi Canon EF Lens to Micro Four Thirds Camera Lens Turbo Adapter Mark II.
