PHOTO QUALITY. This 12-megapixel mirrorless camera captured images with very good quality. Pictures were sharp, which means you can see most details and subtle patterns in the image. In low-light situations without a flash, pictures were sharp. We judged this model excellent for outdoor performance, such as shooting landscapes in the daytime; very good for indoor performance, such as photographing a well-lit basketball game in a gym. And very good for low-light performance without a flash, such as capturing a birthday party. Photos taken in our low-light performance tests displayed very little image noise; subjects retained correct detail and color.
FLASH. This model has no flash.
LENS. This camera has a standard 3x optical zoom lens. The lens also has very wide-angle (24mm) capability that's very useful for landscapes and group portraits, although you may notice a bit of distortion when you're shooting faces up close, for instance.
IMAGE STABILIZATION. This is an important feature; taking hand-held shots at the telephoto end of the zoom range can generally blur or soften images due to the slight movement of your hands. In low-light settings, it performed well but sometimes produced blurry photos. Overall, the shake reduction results from our tests were good.
SPEED. In terms of performance, the Sony Alpha A7S w/ T FE 24-70mm f/4 ZA OSS powers up very quickly. It has a short interval between shots, which can be important when shooting fast-moving or unpredictable subjects.
VIDEO. The Sony Alpha A7S w/ T FE 24-70mm f/4 ZA OSS takes excellent video. It also captures 4K-UHD video at 3840 x 2160 100p. As for sound, it captures very good audio in stereo.
ADDITIONAL COMMENTS. Like most mirrorless models, this camera does include an electronic viewfinder, which means you have flexibility when composing your photo or video; this viewfinder has excellent quality.
