Just to understand better :

  • How do 15 and 45 lw/mm translate in terms of number of pixels ?
  • What are exactly Sagittal and Meridional ? Are really lenses performing so much differently regarding the orientation of lines to resolve ?

- I think 45 pair of lines per mm requires a minimum of 7 MP.

- Astigmatism: See
