The Optio A20 is the latest model in the premium Optio A series range.
Housed in a tough, lightweight aluminium casing the Optio A20 offers 10
effective megapixels, and has a range of features, including three
types of anti-shake function. The Pentax developed SR (Shake Reduction)
technology reduces camera shake by using gyroscopic sensors to
oscillate the CCD as the camera moves, ensuring crisp images even when
the camera is moving. To further improve image quality Blur Reduction
optimises the settings for crisp images in any conditions and the Auto
Tracking AF function, ensures the subject of the image remains in focus
even if it is moving, allowing for perfect action shots.
The Optio A20 features a 3x optical zoom, class leading optics and a
2.5 inch low reflection LCD display. This camera will retail for around
£279 and be on sale from early October.
- High Quality Images -10.0 effective megapixels
Despite its compact dimensions, the Optio A20 produces extremely clear,
high-quality images thanks to the high resolution provided by its 10
effective megapixels. This level of resolution makes it possible to
produce prints with crisp detail even when the photo is enlarged to A3
size. The Optio A20 uses a large 1/1.8-inch CCD with a wide light
sensitive area, which enables superior tone reproduction, fine
textures, and greater noise reduction.
- High performance smc PENTAX zoom lens
The Optio A20 is equipped with a high quality smc PENTAX zoom lens,
which is renowned for its clarity and high contrast image performance.
Its lens configuration, with seven elements in five groups, including
three aspherical elements, effectively corrects for spherical
aberration. The lenses are coated using a Pentax developed technique,
which greatly reduces ghosting and flare.
- New ASIC
A new ASIC supplies the Optio A20 with increased image-processing
power. Thanks to the ASIC’s high-speed processing capability,
the Optio A20 attains a higher level of tone reproduction and colour
correction based on enormous amounts of actual photo data.
- Three Types of Anti-Shake Functions
SR (Shake Reduction) - The SR mechanism, developed by Pentax, features
two gyro sensors that detect the amount of shake and moves the image
sensor (CCD) horizontally and vertically counteract camera shake. The
SR mechanism effectively prevents shake the instant that the shutter
button is pressed.
Blur Reduction mode - In this mode, the camera automatically adjusts
the sensitivity to as high as ISO 1600 according to the brightness of
the subject. The higher sensitivities permit faster shutter speeds that
reduce camera shake and blurring caused by moving subjects.
Movie Anti-Shake Function - Camera shake while taking a movie can also
be corrected automatically by software, thanks to an electronic, movie
- Face Recognition AF & AE for beautiful
The camera includes the new Face Recognition AF & AE*4
function, which allows you to take photos of people with perfectly
focused faces free of shadows, frequently caused by exposing for the
background or for bright clothing. This useful function automatically
detects the position of the subject anywhere in the photo frame and
then adjusts the focus and optimises the exposure for the detected
- Auto-tracking AF continuously focuses on a moving
The Optio A20’s Auto-Tracking AF feature continuously focuses
on subjects as they move around. Since the focus frame automatically
follows the movement of the subject inside the photo frame, you can be
sure to capture those instantaneous photo opportunities. This setting
is perfect for photographing kids, pets or sporting events.
- High quality movies with an anti-shake function
The Optio A20 smoothly captures movies at 30 fps (frames per second) at
sizes up to 640 x 480 pixels with image quality rivalling camcorders.
Since it employs the DivX® (MPEG-4 compliant) movie format,*5
the Optio A20 can record longer, high-quality movies.
- Auto Picture mode automatically determines the
best settings for the shooting conditions
The Auto Picture mode lets the camera automatically determine the
shooting conditions for Landscape, Portrait, Night Scene, and Program
modes and choose the optimum settings for each subject. This Pentax
developed function makes photography a lot easier for users since it
eliminates the need to adjust individual settings. However more
advanced users still have the option to manually adjust all settings.
- A wide range of exposure setting modes
In Programmed Exposure mode, the camera automatically determines the
shutter speed and aperture. The camera also includes
‘Shutter-Priority AE’ mode and ‘Manual
Exposure’ mode, which the user can set freely depending on
the effect they are aiming to achieve.
- Compact and lightweight body
Despite incorporating a large CCD and the SR System, Pentax have
created a slimmer and lighter body by using our unique Sliding Lens
System together with high-density mounting technology.
- Supports the SDHC memory card for greater storage
of high-quality images and longer movies
The Optio A20 supports two removable storage media: the conventional SD
memory card and the new SDHC memory card.
- Red-eye correction available after shooting
The Optio A20 comes with FotoNation’s red-eye correction
function, which can correct red-eye problems, a common side effect of
flash photography, after the photo is taken. With the ability to
manually select the area to correct, this function allows for more
precise correction of red-eye photos.
