New BV(RI){sub C} measurements of Praesepe made at the South African Astronomical Observatory (SAAO) are presented. When those measurements are combined with those reported in previous papers in this series, it is found that they support previously determined V zero points for Praesepe, M67, and the Hyades. Support is also found for joint (V - R){sub C} and (R - I){sub C} zero points established previously for Praesepe and NGC 752. For the SAAO system of standard stars, a B - V correction to the Johnson system of about -9 mmag appears to be reasonably well established. The preferred (though not definitive) V correction is about +7 mmag. For the Landolt V system, zero-point identity with the Johnson system at a 2{sigma} level of 4.8 mmag is found, and no color term as large as 4 mmag (mag){sup -1} is detected. Updated CDS data files for Praesepe are briefly described.
