Thanks Fons and Frank.
A large number of raw-converters can't handle the Fuji S5 files. ACR can. Also s7Raw is useful and creates a 4.256 x 2.848 - 80.2MB 16-bit Tif - file. That software can even identify the R and S pixel, where the S pixel picks up the brightest details. That brightest details makes the sensor unique. Plus the fact the S5 accepts all Nikkor lenses.
Very interesting Pano, Frank
That must be a high ISO fish, Fons, or is it the IR-effect?
