Q: 1. I will buy the new canon m6 mark ll. will this work on it? Will I geht more focal, aperture and wider view? Thanks

A: The Metabones T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Canon EF-M Mount Camera will help reduce the crop factor that occurs with using an APS-C size image sensor camera such as the Canon M6 Mark 2. Normally if you used the Canon adapter on the 50mm f1.8 lens, it would look like an 80mm f1.8 in comparison to 35mm film or a full frame camera. But with the Speed Booster, the crop is reduced by 0.71x so a 50mm f1.8 would look like a 57mm lens with an f1.4 aperture.

Q: 2. Will this adapter work with my crop sensor EF lenses?

A: Any EF lens will Mount to this adapter, but a cropped EF lens will produce an image with a black circular border. For cropped EF lenses, it would be better to use an EF/Fuji-x adapter that does not have any glass in it, they are very cheap.

Q: 3. Why is the Canon EOS c200 not listed as compatible?

A: Not every camera it is compatible with is listed. The C200 has an EF mount. It will work well with this lens.

Q: 5. There is almost nothing on the internet about this lens. Id really love to use this lens wide open but typically Rokinon Cine lenses need a stop down to get sharp. Anyone know any really good comparisons with this lens at different Tstops from T2.6 down to its minimum aperture? I know its a Cine lens but would be great to see some high res photos for comparison.

A: We are not aware of any specific locations showcasing examples of this lens at different apertures. You could however check on websites like Youtube and Vimeo to see if anyone has posted examples.

Q: 6. Does this give the lens autofocus abilities canon cameras?

A: Since the Canon CN-E 20-50mm T2.4 L FP and the CN-E45 135mm T2.4 L FP PL-Mount Flex Zoom Lenses lack motors for either focus or zoom, the Canon EF Mount Kit for 20-50mm T2.4 L FP & CN-E45 135mm T2.4 L FP PL-Mount Flex Zoom Lenses cannot make either lens auto focus.

Q: 7. Dan, In your response to Muhammed you said "a 50mm f1.8 would look like a 57mm lens with an f1.4 aperture." You said it has a crop of 0.71 so don't you mean it would look like a "35mm" lens with an f1.4 aperture? Was "57mm" correct?

A: 57mm is correct.

Q: 8. Does this EF mount kit work with other EF mount lenses?

A: No, the Canon EF Mount Kit for 20-50mm T2.4 L FP & CN-E45 135mm T2.4 L FP PL-Mount Flex Zoom Lenses is designed to replace the EF mount on the Canon CN-E 20-50mm and 135mm lenses, it is not a lens adapter, it's a replacement mount for those lenses.

Q: 9. Does this lens have a protruding T ring in that the rear plastic is uneven ? I had an issue with an EF Lens that would not fit on a C100 due to this protrusion. Thanks

A: This Rokinon lens with EF mount would fit and work with your Canon C100 camera. There should be no issue with the gears on the lens effecting mounting with your camera model.

Q: 10. Will this work with S35 v-Raptor?
