Of course you can export the Hassi files to DNG out of FC - no problem at al. The only drawback i am aware is in your case that the DAC optimization will not be in the DNG files.
According to Hasselblad Tech Support,
"The 1st level of the DAC correction (chromatic aberration) will be preserved in the DNG file.
But not the 2 other levels, lens distortion and vignetting"
Thus, I just convert to DNG and do any lens distortion and vignetting correction in Photoshop.
Flexcolor is just not an option.
Do other users agree?
