I don't actually use m43, but 16 or even 24mp would be rather inadequate for my needs, especially from a bayer sensor.

I do my printing at 720 ppi on Pictorico OHP transparency stock, which I then use to contact print cyanotypes or pt/pd (I'm really dedicated to useless stuff). You can see how the resolution requirements for anything bigger than a postcard are stringent.

In practice I use either a Sony A7r (36mp, with very sharp primes) a Sigma with a foveon sensor (which holds up very well to the Sony at ISO 100, and it's not like I use the Sony at more than ISO 100) or high-resolution scans from Adox CMS20 II microfilm stock (ISO 20, there is a special low contrast developer for pictorial contrast) shoot on a Leica or Contax with their respective very highly resolving primes.

Gotcha. Cool setup!
