Originally posted by Saxplayer1004 looks like it might have wireless with the IR plate up front. May be through the mode button instead of a switch. Either way I'm liking what I see so far...
...or the Fn button.
At first glance of the control panel though, its clear to me that Pentax has moved to buttons and dials rather than exposed switches. My feeling (not professional opinion) is that buttons are easier to weather seal - via a simple O-ring - than switches are. Perhaps Pentax is indeed looking at weather sealing their flash system to match the ruggedness of their cameras? That alone would justify the cost to go with a Pentax flash over a 3rd party Metz/Sigma...at least to me.
The metal shoe is a welcome addition!
