Related Questions and Answers

Q: 1. How does it work for video? Without IS, does it work well for video? 18-150 is a bit heavy/poorly balances on the gimbal.

A: If you used this lens on the Canon EOS M50 which has 5 axis stabilization, then this would alleviate the need for stabilization in the lens. If using it on an EOS M camera without stabilization for video, then using a hand held gimbal is the best way to add stability.

Q: 2. Is the focal length before or after the 1.6x crop?

A: The actual focal length of the lens is 22mm. It is equivalent to a 35mm lens on a 35mm film frame.

Q: 3. Is this Lens work with 5D Mark III ?

A: Nope. This lens is designed for Canon APS-C mirrorless cameras. Like the M5 and M6.

Q: 4. can this lens be used on a EOS DSLR?

A: No, unfortunately it cannot. I think the M in EF-M means that it is intended to be mounted on a mirrorless camera. That is a different mount than the EOS DSLR.

Q: 5. Is there an adapter for this lens to go on a e mount camera like the Sony a6500?

A: Unfortunately, B&H does not carry adapters for the Canon EF-M mount lenses. Im not aware of any options on the market that would enable one to mourn an EF-M lens onto an E-mount camera.

Q: 6. Focus is internal or external? Barrel comes out or is internal?

A: focus on the lens is done internally

Q: 7. just autofocus or it can be manual?

A: Yes. It has auto and manual focusing.

Q: 8. Does this come in black??

A: yes it does

Q: 9. If Canon launches a full frame mirrorless camera in the future, will this lens fit that particular camera?

A: Hard to say until the camera is released. If the camera uses the EF-M lenses then possibly but the lens is made for APS-C so it would crop..

Q: 10. Will the OIS work going through a Metabones?

A: It would depend on the adapter and the camera you own to see if the adapter would transmit auto exposure, autofocus, and image stabilization information to the camera. As the camera you own was not listed above, I would have to recommend e-mailing your inquiry to prophoto@bhphotovideo.com with the brand/model of your camera. and we could then see if there is an adapter that would retain autofocus/auto exposure/image stabilization capabilities.
