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


Within the EU, the goods usually arrive within a few working days. Deliveries outside of the EU can take from just over a week to two weeks. Even an exchange or return within 14 days can be handled more quickly, cheaper and less complicated on the MJKZZ.DE page, if the items only need to be sent back to Germany/Austria. For large orders OUTSIDE of EU contries, it is possible that the shipping costs need to be calculated manually becasue of insurance. But we only charge the real shipping costs!

If you are ordering OUTSIDE of EU: Please contact us to place your order without VAT. We will send you an invoice excluding 20% tax.
