This conversation has been merged. Please reference the main conversation: Lightroom: When will my camera be supported for Tethering?
I use LR4 and a Pentax K5. Adobe must be pleased that Pentax is one of the few manufacturers to support DNG format. It seems surprising that Adobe has chosen not to offer tethered shooting with Pentax.
Is Adobe planning to support Pentax tethering?
Lightroom tethering relies on SDKs provided by camera makers - if Pentax doesn't produce an SDK which includes the relevant control hooks for Lr to base tethering on, it can't happen.
