发帖数: 41892 | 1 Improved AF speed and accuracy due to the introduction of the Hybrid AF
system
The camera comes newly equipped with Ricoh's independently developed
external AF sensor, which has a maximum of 190 AF points. Through the Hybrid
AF System, which is used in parallel with the conventional CCD contrast AF,
Ricoh has realized an AF focusing time as short as 0.2 seconds, as much as
half that of the GR DIGITAL III.
Also, algorithm refinements have led to improvements in the AF speed for
macro shots that are taken using only the CCD contrast AF method for a
maximum reduction of half the time of the previous model.
In shooting with a single press of the shutter-release button, the high
focusing accuracy required for snapshot shooting has been added to the
camera's Quick Shooting capabilities by performing the metering with only
the external AF sensor. The metering information from the external AF sensor
can be displayed on the LCD monitor as necessary.
光线是以何种方式抵达external AF sensor的？
