I've done a lot of Minox 8x11mm photography over the years.
Even a 4000 ppi scanner will only net lowish resolution photographs from Minox 8x11mm negatives: a 4000 ppi scan of an 8x11 negative nets a 1260x1732 pixel image, about 2.2 Pixels. Printed at 240 ppi, that nets an image area of 5.25 x 7.25 inches, and the negative better be very sharp and clean for it to look good.
I switched to a 24 Mpixel copy camera setup. This is the Leica SL I used to use, with Leica Focusing Bellows-R and Summicron-R 50mm lens to do Minox negatives:
This setup nets enough magnification to obtain a 21-22 mpixel digital image that you can do a lot with.
You can see the difference in quality instantly between these photos and two older scans made with a Nikon CoolScan V ED negative scanner:
I've now switched to using a Leica CL setup, same lens and bellows as above. This has advantages over the SL for this kind of work ... the CL's smaller format has the same pixel resolution as the SL (24 Mpixel) so the amount of magnification required to capture a Minox negative is quite a bit lower, which means less potential for vibration, etc, and the output is equal in pixel count and quality.
So if capturing Minox negatives is a goal, I'd pick a good used mirrorless camera with an adapted 50-60 mm macro lens. A good tripod or copy stand, and a clean light source, will make the job go quickly and consistently.
