SDQH has more resolution and less artifacts than Fujifilm.

The new 70mm macro is the best lens for your purposes. Adapting Nikon glass is somehow frustrating.

I did all of mine with an adapted Olympus OM 80mm lens, originally designed for copying 35mm film. Once you get it set up, and adapted lens is no problem.

However, the 70mm would probably work very well. Has anyone seen one yet ?

Raw developers other than SPP are not optimal. There is no such thing as linear dng with Sigma cameras. The sensor produces a completely different kind of signal and you probably should use the 16bit TIFF output from SPP.

I used the DNG format output from the sdQH for all my B&W 35mm negs. It worked very well. I haven't tried colour negs with the Sigma.

Why using film? You could acheive better results by using just the SDQH.

Technically better, but not necessarily aesthetically better. They are different media.

Example Kodachrome slide using the sdQH in SFD mode. You wouldn't need SFD for negs, but the high contrast of slides demands some kind of HDR method.

Note in the full size crop that the grain and the dust on the film are well resolved. Grain aliasing is the big problem when copying film, especially B&W. You can't have too much resolution.

Exakta camera, 25mm Flektogon lens.

You can find examples of B&W negs copied with the sdQH in my posts to the Monochrome Photos threads.
