Note: The equivalent is for field of view only — for depth of field and noise, the aperture is also affected by the crop factor.
Tips
- A 50mm lens on a 1.5x crop sensor frames like a 75mm on full frame.
- Portrait shooters often prefer the 70–135mm full-frame-equivalent range.
- Remember aperture depth of field behaves differently on smaller sensors.
