I have recently found out about Sofortbild, a new Mac based tethered shooting application that looks to be incredibly comprehensive offering not just tethered shooting, but also time lapse, remote camera control, automatic import of images to Aperture or iPhoto, plus more. The application looks very polished and well done. Best of all it’s free.
Now for the bad news, currently it only supports a number of Nikon DSLRs, but the developer, Stefan Hafeneger states that a long term goal is to include support for Canon as well as some other brands. We eagerly look forward to a future release with Canon coverage.
