Sony Unveils the A57 SLT: Improved Shooting Speed and Autofocus
Sony has announced the Alpha A57 pellicle mirror camera, the successor to its A55 released a year and a half ago. While the sensor resolution is still 16-megapixels -- no megapixel war here -- the new camera has an increased ISO limit of 16,000 (up from 12,800), a faster continuous shooting rate of 12fps (up from 10), and an improved 15-point AF system with enhanced object-tracking and snappy AF during HD video recording. It can also capture full HD video at 60p, 60i, and 24p. It'll be priced at $700 for the body only (or $800 with a 18-55mm kit lens) when it hits store shelves next month.
