Related Questions and Answers
Q: 1. Does anyone know if this works on a GH5?
A: Yes, this will work on a GH5.
Q: 2. I'm unclear if this lens works on a Blackmagic Pocket Cinema Camera without an adapter or not, previous answers are unclear?
A: Yes it does. This listing, B&H # RO1222M43, is for a lens with an MFT Mount. The Pocket Cinema Camera has an MFT Mount.
Q: 3. Can this work for Sony CMOS Sensors? I have a Sony FS700.
A: Yes I am using on my fs700... working great I think rokinon lens work best on Sony camera's
Q: 4. Is this compatible with the AIDA Imaging HD-100?
A: Yes it is. The Aida HD-100A camera has a CS mount that would work with the AIDA Imaging 12mm f/1.6 CS-Mount Lens.
Q: 5. Will this lens fit on a Canon 6d? Full frame sensor.
A: No. I order it by mistake.
Q: 6. Will this work on the Panasonic Lumix GX85 camera ?
A: Yes, this is an MFT mount lens which will work on the GX85.
Q: 7. Will this work on the BMCC with a MFT mount? The BMCC has a Super 35 sensor but the description says this Covers APS-C Sized Sensors. Will this create any vignetting on the BMCC?
A: I bought the 12mm 2.2 for the BMPCC, which has a sensor essentially the size of Super 16. I may be mistaken, but I thought the BMCC sensor is slightly smaller that Super 15. I'd recommend you check the Cinematography section of the Blackmagic Design forum to be certain.
Q: 8. Will this work on the Panasonic GH4?
A: Yes it will. Very sharp
Q: 9. Will this work well on the a7?
A: The Sony a7 is a full-frame camera while this Rokinon 12mm T2.2 Cine Lens for Sony E Mount is for smaller APS-C sensors. If you use it straight on the camera in full frame mode, you will see severe darkening of the corners or vignetting. However, Sony is aware of this and has a APS-C mode that is selectable in the camera so in the end, you can use this lens on the a7. It will deliver sharp images, day or night. Just be aware you are cropping the image so you will not get as many MP's out of the image like in full-frame mode. Correctly handled, the difference in image quality is not considered an issue by most pros.
Q: 10. What are some good ND filters as I have purchased one but don't have anything to help fight being overexposed while shooting outside at a wide open aperture in order to get nice bokeh?I am currently shooting on the BMPCC.
A: This lens takes 67mm filters. I suggest for video an ND 9 which is 3 stops of light blockage.Neutral Density filters traditionally are rated: ND 3 is 1 stop, ND 6 is 2 stops, ND 9 is 3 stops and ND 1.2 is 4 stops. You can buy separate filters for each of these strengths or you may choose a variable ND. These work by rotating a sandwich of two polarizing filters. The great convenience is that you have all your ND filters in just one. I prefer solid ND over variable ND filters for their evenness of effect. However, there are others who are completely satisfied with variable ND's. Here is a link to what are the best selling variable ND's.http://bhpho.to/1NISmRFHere is a link to 67mm best selling solid ND's I can suggest.http://bhpho.to/1KL7M8xPersonally, I like B+W for their quality. Read the B&H customer reviews for further guidance as for what is best for you.Finally, here is a B&H guide to using ND filters.http://bhpho.to/1RgawjL
