The Pentax Optio E40 is an affordable, entry-level compact digital camera that features 8-megapixels of resolution, Face Recognition technology and Digital Shake Reduction functions. This model accepts widely available AA batteries and is designed for simple and intuitive operation, perfect for beginners.

The Optio E40 features Face Recognition AF & AE, which allows you to take beautiful pictures of people easily by letting the camera determine the focus and exposure. This "Face Recognition AF&AE" function automatically detects and focuses on faces, regardless of where the people appear in the photo frame. In addition, optimal exposure settings are automatically conducted so that the areas with faces are not darkened even if there is backlighting.

Digital SR (Shake Reduction) mode helps reduce camera shakes and blurring from subject movement in your still images. The sensitivity is adjusted automatically, to as high as ISO 1000, to match the brightness of the subjects. This enables you use faster shutter speeds in marginal conditions, ultimately helping you produce blur free images.

Since the Optio E40 accepts AA batteries, you can shoot with confidence whether at home or away. Furthermore, the camera has been designed specifically to use less power so that you can take approximately 240 photos when running on alkaline batteries.
