Sony's latest Alpha 7 takes on camera shake
MANILA — Japanese consumer electronics giant Sony recently launched the Alpha 7 II, the newest in the Alpha 7 series of interchangeable-lens models, offering the world’s first camera with optical 5-axis image stabilization designed for a full-frame image sensor.
“The arrival Alpha 7 II marks Sony’s commitment towards continuous innovation. We have already witnessed this when we launched the Alpha 7S and Alpha 7R -- the world’s smallest and lightest interchangeable-lens full-frame camera,” said Nobuyoshi Otake, president and managing director of Sony Philippines.
“With the new Alpha 7 II, we carry on the traditions of the Alpha 7 series of outstanding image quality and compact sized cameras that set new standards for professionals and enthusiasts around the world," Otake added.
The Alpha 7 II provides stability by detecting and correcting various camera shake along five axes for still images and video, including: angular shake (pitch and yaw) that tends to occur when shooting with a telephoto lens; shift shake (along the X and Y axes) that becomes noticeable as photographing magnification increases; and rotational shake (roll) that often affects shots at night or when recording video.
The reduction of camera shake is made possible by the 24.3 effective megapixel, 35 mm full-frame Exmor Complementary Metal Oxide Semiconductor (CMOS) sensors. For still images, stabilization is equivalent to up to 4.5 steps faster shutter speed of correction.
The Alpha 7 II also dispenses the tripod when a photographer conducts hand-held low-light shooting at slower shutter speeds. Users can thus enjoy unparalleled freedom with a wide-range of lenses without worrying about camera shake.
They can also monitor the corrected image in real-time on the camera’s LCD screen or in the OLED viewfinder for fine-tuned framing and focusing even when using a telephoto or macro lens.
Overall, users can enjoy beautifully rendered images from the full-frame sensor with the convenience of image stabilization.
The company said a higher form of algorithm is used to detect the subject position, enabling optimal lens drive. In a variety of scenarios, autofocus is very responsive – 30% faster than in previous models. An improved Sony algorithm for the prediction of moving bodies results in a 1.5 times improvement in performance in tracking a subject and predicting its next movement.
The Alpha 7 II is priced at P 89,999 (body only) and at P105,999 with 28-70mm lens.
