Please Note

This chart does not conform to the updated ISO 12233:2014 standard. We recommend the Photographic ISO 12233:2014 E-SFR chart for testing that does not specifically require the old chart.

The ISO Camera Resolution Chart conforms to the ISO 12233:2000 standard, “Photography-Electronic still picture cameras – Resolution measurements”.  This target’s active area at 1X size, measures 20 cm high and has features of 0.1 mm.  All features vary as a multiple of the overall chart size.  Hyperbolic wedges for resolution evaluation range from 100 – 2000 lines per picture height.  Other features include checker patterns, multiple slant-edge lines, a center-focus zone plate and framing marks for 1:1, 4:3, 3:2, and 16:9 aspect ratios.


Our product pricing and shipping rates do not include import duties, taxes or fees. The customer / recipient is responsible for these expenses.


Notes: This chart is used to measure sharpness from slanted-edge patterns (as Spatial Frequency Response = SFR) using the Imatest SFR module. It can also measure resolution from the hyperbolic wedges using the Imatest Wedge module (a part of Rescharts).
