Assertion: lens's distance | /r/HasSubevent | discoloration
Facets:
value: due to sensor microlenses
type: CAUSE
Source sentences:
text: Also, the shorter flange distance can lead to increased vignetting or discoloration in the corners of an image (although this can be mitigated by making the lens design longer to simulate a longer flange distance), due to sensor microlenses not being able to pass enough light at extreme ray angles.
