I am pleased to announce that Sony has released 4 new cameras last week, showcasing some innovative features as well as developing their new translucent mirror cameras. Firstly, I'll start off with the traditional DSLRs which replace the a500 and the a550. The newly developed a560 and a580 DSLRs both have new sensors and are one of the first DSLR cameras from Sony that can now record HD video up to 1080i, shoot up to 7 frames per second, have a new 15-point autofocus system, 3D sweep panorama, 3 frame HDR and has an extended ISO 25600 (Multi-Frame NR mode). These are great cameras for the enthusiast photographer, that produce great images even in low-light. The only thing that I can think of that Sony should have put in is a dedicated AF assist lamp but I guess they'll reserve that for their higher up models.

Now these cameras that I am about to talk about are not DSLRs but are called Digital Single Lens Translucent (DSLT) cameras because the mirror doesn't flip up in a reflex motion, instead they are fixed semi-transparent mirrors. The advantages of this new technology means that the cameras can shoot at a blazing fast rate. On the a55 it can shoot up to 10fps with continuous phase-detection autofocus, even when recording movies. Also there is no mirror blackout when taking a photo, no mirror movement compared to traditional DSLRs, shorter shutter lag and it allows the user to have a more compact body. The following a33 and a55 is a great innovative step for Sony in the camera market and I'm even considering buying the a55 for its performance and quality. Here's a video showcasing its headlining its main features:
