DSLR scanning vs. Epson V800 scanning

I am scanning 35 mm to 5 x 7.

Can I acheive Epson V800 like results using a Nikon D500 or D5600 without stiching with a good Macro lens?

Thanks.

It certainly made clear a lot of the optical phenomena I'd encountered over the years from Epson scans - much more so than the (frankly rather useless) resolution tests that proliferate across the internet. For my own amusement about a year or so ago, I did actually see if I could recreate the 'look' of an Epson scan by combining 2 slightly offset 1200ppi scans from a high end CCD scanner & upsampling them to 2400ppi - and the resultant file had the rather distinctive characteristics of an Epson scan result - the resolution looked slightly higher than 1200ppi (maybe heading towards 1500-1600ppi in terms of useful resolution - even if nominally 2000+), but a native resolution scan done at 1600ppi on the aforementioned CCD scanner blew away the blended 2x 1200ppi in terms of the important noise:sharpness ratio. The relationships of sharpness, noise, latitude (bit depth too) and colour handling really matter a lot more to a good scan result than any high contrast resolution test.

For 35mm, DSLR digitizing will probably be very close in useful resolution to the Epson. For any other format, you'll have to use stitching to beat the 2400-2800 PPI resolution most people are able to extract with the Epson.

interneg apparently was apparently bullied by an Epson in his youth-- the results of the somewhat questionable paper he references are flatly contradicted by real-world experience, and in spite of his claim of "(teardown based) considerable level of detail", provides one measurement, and a whole lotta assuming. Further, the paper was written about 5 years before the introduction of the v800, which is known to have better (even if only slightly) scanning resolution than the v700.

I am scanning 35 mm to 5 x 7.

If you have the camera & lens, try it. It'll tell you enough as to how you should proceed very, very quickly. If necessary, renting a suitable lens to try should be fairly straightforward too.
