2. OVERVIEW
2.1 EOS D60 body
While retaining the best features of the EOS D30, the EOS D60 has many more
pixels and new and improved specifications desired by users. The EOS D60's
improvements over the EOS D30 are outlined below. (All specifications not
mentioned below are the same as the EOS D30.)
1) Imaging element
• Newly developed, large CMOS sensor with about 6.30
megapixels
The large CMOS sensor has 6.30 effective
megapixels (out of a total of about 6.52 megapixels),
an effective sensor size of 22.7
×
15.1 mm (same as
the EOS D30's), aspect ratio (2:3), large single
CMOS sensor and separate filters for the three
primary RGB colors. It boosts the camera to the top
of its class for fine image detail and image quality.
• Red ghost countermeasures
With the EOS D30, red ghost outline sometimes appeared near a bright light source
or at a symmetrical point in the field. As a countermeasure, the EOS D60's low-pass
filter configuration has been modified. The IR filter is a hybrid with a coating and
absorption function to suppress red ghost.
2) Viewfinder
• Superimposed (SI) display
The same SI optics found in the EOS 55/ELAN II/50 has been incorporated in
front of the pentaprism so that the AF points can be illuminated.
•
Easier manual focusing
The New Laser Matte focusing screen has improved diffusion characteristics to
make it easier to distinguish peak focus.
3) AF
• Improved AF operation in low light
With the EOS D30, AF operation was possible in the EV 2 - EV 18 range. This
has been improved to EV 0.5 - EV 18 (normal temperature with ISO 100) with
the EOS D60. The algorithm for the AF-assist beam has also been modified to
improve AF operation in low light.
4) Metering and exposure control
• Shorter and more stable shutter release time lag
With improved firmware, the shutter release time lag is much shorter and more
stable than the EOS D30's.
