Fujifilm GFX100: File Sizes in 16-bit vs 14-bit Capture

The Fujifilm GFX-100 offers lossless-compressed raw file captures (the ideal format) in both 14-bit and 16-bit captures, as well as uncompressed files.

How much space does lossless compression save in practice?

These figures stem from 4811 files shot during a 2.5 week trip field shooting the GFX100. Nothing more real-world than that!

Most images were 14-bit lossless compressed shot for FOCUS BKT images for focus stacking.

3593 files, 14-bit: average size 97.0 MB   ~= 54% savings
1218 files, 16 bit: average size 124.15 MB ~= 41% space savings
