Just Posted: Our review of the Sony Alpha SLT-A99. The A99 is Sony's flagship SLT camera - featuring a 24MP full-frame sensor and dual AF system, along with the level of build and direct control you'd expect from a range-topping model. We've put the A99 through its paces in a variety of situations, including an investigation of how its AF depth control performs in challenging shooting conditions. We've also looked at the advantages the SLT system and articulated screen bring to a camera at this level, as well as looking at their downsides.
