Yet another new camera announcement for today. This time it’s Sony’s SLT-A77, the SLR equivalent of the NEX7 mirrorless compact, also announced today.
The A77 has two very cool new features. First is Sony’s new translucent mirror tech. This uses a pellicle mirror instead of the usual silvered glass panel. It lets the light pass through to the sensor, yet allows some (in an SLR) to be reflected up to the viewfinder. That means you can shoot very fast because the mirror isn’t constantly slapping up and down like a stupid dog’s tongue on a hot day.
But the A77 doesn’t have an optical viewfinder. In this case, the mirror is used to siphon off some light to the phase-detection AF system, which lets it focus as fast as an SLR, and yet still manage a live-view. And what a live view. This one comes courtesy of the 2.4 million-dot finder, also found in the NEX7.
The lack of a mirror also speeds things up. The A77 can shoot its huge 24-MP images at an almost absurd 12 fps.
You also get a maximum ISO of 16,000 (it’s the same sensor found in the NEX7), 1080p video, a 921,000-dot LCD and a mess of in-camera special FX.
How much does Sony want for this beast? Body only, you’ll pay around $1,400. It should be available in October.
