Magnification Calculator vs Macro Magnification Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Magnification Calculator
Compute the optical magnification of a lens or mirror by comparing the image height to the object height. Use it to determine whether a lens enlarges, reduces, or inverts an object.
- Answers
- Magnification (×)
- Inputs
- Image Height, Object Height
Macro Magnification Calculator
Compute the image magnification ratio and effective coverage area for macro photography, factoring in focal length, extension tubes, subject distance, and sensor size. Use it to predict how large your subject will appear on the sensor before you shoot.
- Answers
- Magnification Ratio (:1)
- Inputs
- Lens Focal Length, Extension Tube Length, Subject Distance, Sensor Width
