Sony's mirrorless cameras are usually well-regarded, but their support for remote control? Not so much. You've usually had to rely on Sony's own software, making the cameras non-starters for portrait and sports photographers who may need (or just prefer) third-party options to capture images from afar. The company is loosening up, at least. It just released a toolkit, the Camera Remote SDK, that allows any developer to create remote controls for Sony's Alpha camera line. The kit is limited to handling still shots, but should let software and hardware display live previews, change settings and of course take pictures.
