I’m receiving many request and questions about LiveView mode in PK_Tether.
Answer for this is simple – PK_Tether couldn’t provide LiveView. Protocol for remote control was introduce by Pentax when LiveView wasn’t available in camera, and probably it doesn’t provide any function for that mode. LiveView also was’t available in official Pentax Remote Assistant for K20D, which confirms my suspicions. Additional because Pentax didn’t release any software for remote control after K20D it probably didn’t change anything in protocol. Even if any command for this mode exist, then for use it in PK_Tether I need some documentation or working product for reverse engineering.
Conclusion is – it is very unlikely that LiveView will be ever possible in PK_Tether.
