Leica SL Typ 601 camera LOG gamma problems reported

Some LOG gamma issues with the Leica SL Typ 601 camera were reported online:

“I first noticed it with the lens cap on that the blacks in LOG mode seem to start around 100 on the 0-255 luma range. This makes the footage essentially un-gradable, severely limits dynamic range and is an obvious flaw. […] The camera seems to compress everything into about half of what is available on the 8bit space. You may say LOG is supposed to bring the blacks up and not crush but this is a bit ridiculous. The blacks are light grey in LOG on the Leica SL!”

“This little test backs up the suggestions made by Andrew Reid that perhaps the SL 601 is unusable in its current state for proper grading of video and that maybe their engineers should take a look at their figures. Analysing Log material from other cameras it appears that Leica are leaning +255 data values towards white, generating a well washed out Log look at 512 to 1023 in these 8-bit recordings.” (Newsshooter)

The Leica SL Typ 601 camera is scheduled to start shipping next week (Saturday, November 21st, 2015):
