I adapted and modified my ultrafast ultra rare lens for use on my A7. There is one on Ebay or $25,699.00..I got my a bit cheaper and made a Backstory/Review/Sample/How To video about it.

Youtu.be

If you get two sets of 77mm diameter close-up filters with +1, +2, and +4 diopters and put them all together, the result is approximately a 71 mm f/0.92 lens.

I would like to thank you for posting your video! You certainly do have a creative mind and a unique ability to find solutions to challenging engineering problems. I went to YouTube so I could view the images that you took with this lens on my large monitor screen. I was very impressed with some of the photos that you posted! Some had a very unique and artistic bokeh that I found very attractive. While not an every day lens, your latest creation is certainly a lens that given the right subject, can produce a unique look that bokeholics (like me) would love.
