The silver, FUJIFILM X-mount Rokinon 8mm f/2.8 Fisheye Lens for FUJIFILMis a prime fisheye lens specifically designed for APS-C sized image sensors. Providing a 35mm-equivalent focal length of 12mm and full 180° angle of view, this lens is well-suited for creative applications as well as interior and architectural subjects. Its fast f/2.8 maximum aperture is further beneficial to working in low-light conditions.

Three extra-low dispersion elements and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, the lens' design features a built-in lens hood and a UMC coating has been applied to the lens elements to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.

Q: 1. Is it compatible with the Canon EOS M6 Mark ii camera?

A: Yes, this lens is compatible with the M6 Mark II.

Q: 2. it is made of plastic ?

A: The lens is mostly metal. It is a solid well made lens. The focus ring is a bit stiff but you don't need to do much focussing.

Q: 3. Will this work with a Canon EOS T6i?

A: Nope it only fits on mirrorless mounts, this particular one fits on the canon ef-m mount that is smaller than canons normal DSLR EF-S or EF mount. I'm 80% sure there aren't any adapters available either. Luckily, there are lots more lenses available for cameras like the T6i, so it should be easy to find a cheap, good quality fish eye that works with that particular mount.

Q: 4. How to attach filter to it?

A: There isn't a way to apply a filter to this lens. You would need to handhold one in front.

Q: 5. Will this work on a Canon Rebel T7i?

A: Unfortunately not as this lens is not designed for EF and EF-S mount cameras.

Q: 6. Should I buy this or the Sony 16mm with fisheye and/or ultra-wide adapter? I already have the Sony combo, but want to do stereoscopic photography so need one more ultra-wide setup.

A: If I was looking for something more ultra wide I'd go with 16mm or even 12mm. This lens is very fisheyed and distorted, so it depends how much width you'd want in your photos, but this is very wide and creates a fisheye look if that is what you want.

Q: 7. Can I use this lens on a Canon SL1?

A: No, they are not compatible.

Q: 8. how to use filter or holder for this lens?

A: The hood is built in. Lens is not threaded and not really able to attach filter or holder.
