Crop Factor
Equivalent focal length and aperture between sensor formats.
Equivalent focal 40mm
Equivalent aperture f/3.4
Source crop factor ×2
Target crop factor ×1
Aperture equivalence covers depth of field and total light gathered. Exposure itself is unaffected — a meter reads the same at f/1.7 on any sensor.
