Field Curvature and focusing
8 months ago

1: Is field curvature and distortion (optical, rather than the appearance of distortion when you do a head shot with a 24mm, for example) the same thing?

2: If a lens suffers from this (or one or the other if they are different) does it mean that using focus and recompose with a shallow aperture will focus in what appears to be focusing errors and therefore, should you only move the focus point on these kind of lenses instead?

Thanks!
