With the focus on Sony’s SLT technology-wielding Alpha 33 and 55 cameras, have we all been passing over a perfectly capable DSLR? Sony offers up the Alpha 580 for your consideration
As mentioned, the Alpha 580 features a new 15-point AF system, with three cross-type points. This is the same system as that used in Sony’s SLT models and, as with those cameras, the AF has been improved.
There is the choice between contrast- or phase-detection AF in focus check live view. During continuous shooting and for moving subjects, the AF is most effective for objects centrally placed in the frame.
