Related Questions and Answers

Q: 1. Is there a way to secure the adapter when using larger (cinema) lenses?

A: While the Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter could not be secured, you would have to secure the lens itself.

Q: 2. Will the Viltrox EF-L adapter allow full Canon EF lens to Leica CL body communication as well as IS, auto focus and auto aperture setting?

A: It depends if the specific lens that you are using was setup in the firmware that the adapter has. If it was autofocus, body communication, IS, and auto aperture will work. I don't see a compatibility list online though so only way to know is to try it out. Also bare in mind that autofocus tends to slow down with the adapter, specially in video mode it tends to be only manual focus.

Q: 3. Does the adapter come with an ND filter? If so, what strength?

A: The Meike Drop-In Filter Lens Adapter for EF/EF-S Lenses to Sony E-Mount Cameras with Variable ND and UV Filters has a 1.5-9 stop variable ND filter.

Q: 4. Will this work to adapt Canon NFD lenses to the Sigma FP? The Canon lenses are already converted to EF mount.

A: A native Canon FD-mount manual focus lens designed for use on manual Canon 35mm SLR cameras would not be compatible for use on the Viltrox EF-L Lens Mount Adapter for Canon EF or EF-S-Mount Lens to L-Mount Camera. However, if your lens was somehow converted to a native Canon EF-mount lens mount, then yes, the above lens mount adapter would be compatible for your usage needs.

Q: 5. What is the filter size? Will it accept 2 inch astro filters?

A: The Meike Drop-In Filter Lens Adapter for EF/EF-S Lenses to Sony E-Mount Cameras is a proprietary holder with a custom size to fit the manufacturer's filters.

Q: 6. What are the ND filter stop ratings?

A: There are no ND filters included in the Meike Lens Mount Adapter Kit for Canon EF-Mount to RF-Mount Camera: there is a clear filter, a circular polarizing filter, and two diffusion filters.

Q: 7. Would this adapter work with the locking mechanism of the RED Komodo X?

A: The Meike Drop-In Filter Lens Adapter for EF/EF-S Lenses to Canon R-Mount Cameras with Variable ND and UV Filters would also support the RED Komodo-X Cinema camera.

Q: 8. Will the IS on EF lenses work with this adaptor?

A: As the Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter does have electronic contacts to maintain electronic communication between the camera and lens, it should still maintain autofocus and image stabilization communication capabilities when used with Canon EOS R-series mirrorless digital cameras.

Q: 9. Will this adjust the lens data sent to RED Komodo? So the correct aperture and focal length shows?

A: The Meike 0.71x Speedbooster Adapter for Canon RF Mount Camera to EF Mount Lens is capable of passing the data, but is intended for mirrorless cameras. It has not been tested on a cinema camera, like the RED DIGITAL CINEMA KOMODO 6K Digital Cinema Camera (Canon RF), B&H # REKOMB. There is the Canon Mount Adapter EF-EOS R 0.71x (B&H # CAMAEFRF71X) that has been tested with the RED Komodo camera. https://bhpho.to/3choaRh
