The PENTAX Optio A40 is the latest model in the Optio A-series of advanced compact digital cameras. Featuring 12 megapixels, this model features three types of Shake Reduction including mechanical, digital and movie. Each version helps deliver sharp, blur-free shots where camera shake is an issue such as action photography or in low light conditions. The Optio A40 also features the newest Face Recognition technology including a Natural Skin Tone mode and a Half-length Portrait mode, which automatically takes a head and shoulder photograph of subjects.

With 12.0 megapixels for higher image quality and enhanced performance, the Optio A40 marks PENTAX's first 12.0 megapixel digital camera. Equipped with a high resolution 1/1.7 inch CCD for a wider light receiving area that is superior in tone reproduction and a new image engine that offers excellent color reproduction.

The Shake Reduction (SR) mechanism is unique to PENTAX, and corrects camera shake when photographing still images by shifting the image sensor (CCD) horizontally and vertically in relation to the amount of shake that the high-accuracy gyro sensor detects. Shake Reduction technology used in PENTAX's digital SLR cameras is applied to the Optio A40 for highly corrective effects that are equivalent to shutter speeds of approximately 2.5 to 3.5 stops.

Digital SR (Shake Reduction) mode automatically adjusts sensitivity, to an ultra-high sensitivity of ISO 3200 according to the brightness of the subject, and effectively reduces camera shake and subject blurring when photographing still images. With fast shutter speeds, photography with reduced blurring is available.

The Optio A40 is equipped with a Face Recognition AF&AE function that automatically detects and focuses on faces. In addition, the Optio A40 also comes with new functions that apply face recognition technology, such as "Natural Skin Tone" mode, which smoothly captures skin texture based on the detected information, and "Half-length Portrait" mode, which automatically takes a head and shoulders photograph of people recognized in photo frame.

This LCD monitor is a high intensity type equipped with an LCD booster that adjusts the brightness of the screen even when viewed outdoors. The 2.5 inch size and high resolution of approximately 232,000 pixels makes it easy to confirm picture composition and focus quality. With a wide viewing angle, the screen may be viewed easily since there is little change in brightness and colors even when looking at the monitor diagonally.

The Optio A40 is newly equipped with a Dynamic Range Adjustment, which helps correct tones for highlight or shadowed areas of a subject with significant differences in contrast. Even when photographing people with sun in the background, the new function highlights subjects and maintains background tones.
