Sony's entry-level Alpha A68 has '4D focus' for low light
Sony just reminded us that it makes more than mirrorless and compact cameras by launching the Alpha A68, an A-mount model with a 24-megapixel APS-C sensor. As with Sony's APS-C Alpha A77 II and full-frame A99 models, it uses a hybrid electronic OLED viewfinder with 100 percent coverage and "faithful color reproduction," according to Sony. That's complimented by a 2.7-inch TFT LCD that tilts 135 degrees up and 55 degrees downwards. The killer feature is the translucent mirror, which allows for what Sony calls "4D Focus" -- a 79-point phase-detection AF that works continuously at up to 8fps, even in low-light.
