Q: 1. what's the difference between defocus smoothing and image stabilization? why eos r doesn't have built in stabilizer which option is the best for me

A: Defocus Smoothing (DS) is a coating on the lens that smooths out of focus areas/bokeh when shooting at wide apertures. It is purely for looks. Image Stabilization (IS) is a mechanism in the lens (and/or body) that reduces blurriness from vibrations, especially when shooting at lower shutter speeds.

Q: 4. Will these lenses work on a Metabones NIKON Speedbooster on a BMPCC? If so, could you also fit an SLR Anamorphot-50 1.33x the front?

A: Yes, this Rokinon set will work with a Metabones Speed Booster XL 0.64x Adapter for Nikon F-Mount Lens to Select Micro Four Thirds-Mount Cameras B&H # MESPNFGM43B2 on a BMPCC. As for the SLR Anamorphot's, it is better if they are attached to a metal bodied lens. Therefore we suggest using SLR lenses as being tough enough and designed matched.

Q: 5. Why is the 16mm APSC/Super35 but the rest full frame? Shouldn't they all be full frame?

A: The 16mm lens in this kit is APS-C, which gears these entire kit towards APS-C cameras. If you are using a Full Frame camera we suggest B&H # ROCLKN (B&H Kit) instead. All four of these lenses cover a Full Frame sensor. https://bhpho.to/2RJpSAN

Q: 6. Is there vignetting seen through these lenses with cameras that have Super35 sensors? (Such as the new Canon C300 MkIII)

A: no, the image circle on these lenses are all designed around the larger FF standard so there are no issues on S35 because the lenses natively cover a larger image circle

Q: 7. Are these lenses for full frame sensors?

A: All of the lenses are full frame except the 16mm which is Super35/APS-C.

Q: 8. Is this lens good for astrophotography?

A: It all depends on the type of composition you prefer shooting. Canon RF 85mm f/1.2L USM DS Lens angle of view is 28° 30' which may be too narrow for Astrophotography compositions. I will recommend starting with a 35mm. There aren't any Canon L series 35mmprime lenses yet. Canon has a 15-35mm ultra wide angle lens on the RF L series.

Q: 9. Does this lens have the 1.9x crop factor? Planning to use it on the new blackmagic pocket 4k as a wide angle.

A: This is an MFT mount lens that will be subject to the crop factor of the camera you put it on. It will be subject to the 1.9x crop factor of the Pocket Cinema Camera 4K.

Q: 10. These lenses is suitable for Sony a6300 APS-c sensor camera? If not which is the suitable lenses for Sony a6300 camera.

A: The Rokinon 16, 35, 50, 85mm Cine DS Lens Bundle for Canon EF Mount, B&H # ROSLKC, listed above are designed for use on Canon cameras that use the Canon EF lens mount. The correct option for your usage needs would instead be the Rokinon 16, 35, 50, 85mm Cine DS Lens Bundle for Sony E Mount, B&H # ROSLKSE, which would connect directly to the Sony E-mount lens mount used on the Sony Alpha a6300 Mirrorless Digital Camera. Do note that these are fully manual lenses, so you would have to focus manually, as well as set your exposure manually and adjust the aperture using the aperture ring built onto the lens.
