1.10 Improved firmware
1) Shorter shutter-release time lag and better stability
The firmware has been revamped for the EOS D60. As a result, the shutter-
release time lag is now shorter and more stable.
Regardless of the shutter speed, the shutter-release time lag (stop-down by up
to 4.5 stops from maximum aperture and excluding AF operation time) will be as
follows:
With SW-1 ON, the time between SW-2 ON and the start of exposure:
Approx. 100 ms.
The time from simultaneous SW-1 and SW-2 ON to the start of exposure:
Approx. 240 ms.
Also, the viewfinder blackout time is about 300 ms. This is about the same as
film-based EOS cameras.
2) Shorter startup time from power off
With the EOS D30, each time the camera started up from power off (main switch
off or auto power off), it accessed the recording media and read the occupied-area
information. For the EOS D60, the firmware has been modified so that the
recording media's occupied-area information remains in the camera's memory
when the power is turned off. Therefore, there is no need to read the occupied-
area information during startup. This makes the startup time shorter.
Since the CF card is a semiconductor integrated circuit, there is little startup
time difference compared with the EOS D30. However, with a MicroDrive storage
device, there is a big difference in the startup time.
When the power is turned off, the camera still detects
whether the CF card slot cover has been opened or
closed. If the slot cover has been opened or closed, the
occupied-area information will be read during startup as
with the EOS D30.
