Upgrade Software Key DMW-SFU1 enables log video
recording (V-Log L) on DMC-GH4* and DC-GH5 to offer exceptional
flexibility as well as wider dynamic range for colour
grading in post-production process.

characteristic curve to Cineon which is a characteristic
curve of film digitalisation. Taking full advantage of Four

12 stops. Both V-Log and V-Log L have the same
characteristic curve and LUT (Look Up Table) can be
utilised in common.
