I used Adobe Camera Raw to invert the DNG files from my sdQH. You can load at least 300 files at a time into ACR and invert them en masse by using the Curves tool (in points mode).
I am satisfied with the results from the sdQH on 35mm B&W negs. Examples I have seen posted by owners of the Sony A7r2 seem equally good.
I had previously copied my 35mm colour slides with an older Sony camera, and the colours seem to me to be better than I have had on a few tests with the sdQH. The Sony cameras have a built in HDR feature which is ideal for slide copying. However, the Sony 42 Megapixel cameras are much more expensive than the sdQH.
I just do the invert by using a batch action invert/save via Bridge in Ps. Same thing ultimately, and you don't have any limits to the number selected. Having an invert function in SPP would make this unnecessary, of course, maybe Sigma will get around to that eventually (or simply supply a proper curves adjustment that isn't anchored at each end).
I bought the sd Q-H specifically for B&W photography and copying, so colour is really not a consideration for me. Used in B&W mode there is no interpolation messing with definition like there always is with Bayer sensors. As the "equivalent" crowd mention constantly, that apparently makes the 25MP sd Q-H sensor easily equal to the Sony 42MP sensor; stitch and the uninterpolated pixel count gets right up there and maybe even betters the best medium format efforts of the Bayer sensor Hasselblad H6D 100C camera in multi-shot mode, not that this means much other than a $1,000 camera equalling the potential of a $30,000+ camera, which as far as I'm concerned is where the argument simply ends.
An unsampled, uninterpolated stitched sd Q-H "scan" of a 120 6x6 B&W neg (one taken on proper B&W film, not that horrible mushy chromogenic faux-B&W/colour-process XP2 rubbish) really has to be seen to be fully appreciated.
