Sony SLT-A57 Review
Interchangeable Lens Camera
Key Features
- 16.1 MP CMOS Sensor
- Bionz processor
- 12 frames per second continuous shooting (Tele-zoom mode)
- Articulated LCD, 920,000 pixels
- ISO 100-3200 (16,000 expanded)
- Electronic viewfinder
- Full HD 1080p movie recording
- 15 point phase-detection autofocus system
- Picture effects
Sony mastered the art of Single Lens Translucent technology with its release of the a33 and a55 cameras. Following on from the success of earlier models, Sony has released the new a57. Boasting some specifications seen in the latest DSLR cameras, this impressive SLT camera is set to rival many comparable cameras on the market.
The new a57 sports a 16.1 megapixel CMOS sensor, Sony’s latest Bionz processor, a 15 point autofocus system, 10 fps continuous shooting (12 fps with Tele-zoom) and full HD 1080p movie recording.
The a57 also boasts a high resolution, 920,000 dot articulated LCD screen along with a high resolution Tru-Finder electronic viewfinder, offering 100% field of view.
The only disappointing news surrounding the release is that Sony has omitted its highly popular built in GPS module in the upgrade. On a positive note this has increased the battery life (a gripe for some with the previous model) however this may not be enough to impressive travelling photographers.
The a57 is a well-built addition to Sony’s SLT range. While the plastic feel will not appeal to everybody the new release still feels sturdy in the hand. The a57 is a responsive and easy to use camera that produces quality images. It will appeal to enthusiast photographers who do not require a built in GPS
