Artist Yoshiro Kobayshi creates pieces styled from Edo period using diamond wheel. This footage was shot in 4K (3840 x 2160) resolution at 29.97 fps using JVC's GY-LS300 (3:18).
I have to confess, I never been a fan of JVC camcorders until I saw the footage of the JVC GY-LS300. In my humble opinion is the best camcorder in its price range whether you using it in 4k or 1080 resolution.
