In stock, ready to ship! You would like to determine your real magnification but a normal ruler is not exact enough? This advanced micrometer calibration tool has 1/100 mm (0.01 mm ), 1/10 mm (0.1 mm), 0.5 mm and 0.07 mm markings on the glass. The tool comes together with a plastic case. How to calculate the exact magnification? For this you need to know length of your sensor and take a photo from this micrometer calibration tool. Real Magnification = Sensor Width in mm / number of mm captured in your photo Example: The sensor size for a Canon APS-C camera is 22.3 x 14.9 mm. If you take a photo from the micrometer calibration tool and cover 3.35 mm width with your sensor then the actual real magnification is: 22.3 / 3.35 = 6,66 magnification Show more
