Can we use a manual mode flash (specifically the Lumopro LP 160) On-Camera as well ? What are the cons of this ?
The only one I can think of is no TTL support.
Note : I will be using this with a Pentax k-x.
(Update : I confirmed from the manual that the flash does work on-camera fine. Would still like to know the cons of using a manual flash, as compared to one with an automatic mode)
My understanding is that a decent flash should have both manual plus automatic modes, and the manual modes typically get used more (esp off-camera). Is this correct ?
