The GX-1S digital SLR combines fantastic ease of use with state-of-the-art optical and digital technologies. This well specified model offers brilliant image quality and easy operation, allowing photographers to focus on what's really important, great pictures.
GX-1S offers a wealth of user-friendly features, including an optical viewfinderfor clear, accurate image framing and a large LCD for displaying and reviewing images, all in a compact, robust body.
GX-1S is ergonomically designed for fantastic ease of use. Made with a light androbust stainless steel chassis, its body weighs only 505g.
The specially-finished grip adds a stable picture-taking capability to this super-light, slim digital SLR. One of many features of GX-1S is the large 2.5" LCD, making it well equipped to display the high quality of the images taken.
GX-1S has adopted the Pentaprism viewfinder to capture larger and clearer images, enabling the user to easily identify subtle changes.
The Pentaprism uses a reflective surface processed with deposition and coating technology that increases optical efficiency, thus ensuring a large and clear view, high magnification of 0.95, and the high picture coverage of 95%, that would be impossible with mirror-based technology.
GX-1S has adopted the 2.1 million-pixel, 2.5-inch large TFT LCD, providing an unprecedented wide and clear screen, enabling the user to review the image more easily, thus enhancing picture accuracy and clarity.
The large and clear LCD also allows the user to easily navigate the camera's menu. This enables the user to control the camera settings, such as resolution and picture quality as well as settings including ISO, white balance, drive mode, and stroboscope.
A separate information LCD on top of the camera makes the GX-1S even easier to use. The LCD displays information about camera operation, including shutter speed, iris value, flash operation, photographing mode, focus, bracketing, white balance, and remaining battery capacity.
Equipped with an 11-point stadimeter high-precision AF feature,GX-1S provides a wide range of AF and AF features. The central 9 points form a cross sensor that adjusts the focus on any horizontal or vertical line.
They offer excellent flexibility in determining the composition by bringing even an off-centre subject into focus.
Additional features include a setting which allows the user to select the position of the AF object, and the display of available focusing points in red.
Equipped with a 16-split photometry system, GX-1S enables accurate measurements of the intensity of radiation and colour distribution based on the AF information even in tricky lighting conditions.
This allows the user to obtain the best exposure for each different circumstance. Available modes are: Multi, Center-weighted and Spot.
