2D plot of ranges of good combinations of exposure time vs. focal length. Calibrated for the Pentax K-7 and its SR system. The bright green represents 1 µm blur or better (0.2 pixels), the red represents 5 µm blur or worse (1 pixels). The intermediate dark green region represents the standard 35mm 1/f rule.

Accuracy of the Pentax K-5 phase detect AF vs. luminosity in EV. © 2011 Falk Lumo. The chart includes all measurements, i.e. various lenses, light colors, distances and apertures. The accuracy is measured as deviation of the focal plane from the sensor plane, in µm.
