A lot of cameras write "lossless" to mean "perceptually lossless". This is easy to do because ~12-bit ADCs have lots of noise in the low order bits.

- matja 1y ago"lossless" has always referred to compression, not sampling - but it seems camera manufacturers want to change that for marketing reasons. Similarly (without starting an audiophile thread): Recording a vinyl record and compressing to a MP3 is "perceptually lossless" but will be different to compressing to a FLAC, never mind that the sampling output will always have random noise.
