A large diameter lens mount and a short register leaves more space
for correcting elements at the rear of a lens unit, used to provide
greater telecentricity to the edges and corners of a large sensor.
Sensor technology may well come to make this less of an issue, with
sensors that can accept light at higher incident angles it may become
a non-issue, but today it is an issue with 24x36mm sensors and very
short focal length SLR lenses, causing light falloff, lower
resolution at the corners and edges, and móire artifacts.
