Description:

This high-end digital compact camera harmonizes high-quality, high-resolution images with intuitive, responsive snapshot capabilities in its compact, lightweight body — making it an excellent choice, even for professional photographers.

To further enhance the essential values of a camera true to the GR-series concept of optimizing image quality, snapshot capabilities and portability, this latest GR-series model is equipped with a complete range of newly designed main components, including a lens, an image sensor and an imaging engine.

Despite a compact body one size smaller than its predecessor, it incorporates a large APS-C-size CMOS image sensor with approximately 24.24 effective megapixels to produce high-resolution images, while its short start-up time of approximately 0.8 seconds allows for quick, responsive shooting.

It also provides an assortment of new features, such as a high-speed hybrid AF system, an originally developed SR (Shake Reduction) mechanism, and touch-screen operation for intuitive control, to improve operability and functionality.

Is the touchscreen glass or plastic?

Quoting from Imaging Resource review of GR iii "...It still has a 3.0-inch diagonal, but now has a wider 3:2 aspect ratio and a capacitive touch-screen overlay on the tempered cover glass which allows it to double as an input device. " So it does seem to have tempered glass screen cover.
