I was playing around with my Pentax k5iis the other day with wireless flash mode. and had some trouble...
I had my settings as this...
-camera in M
-iso 800
-1/30
-F5.6
-first had camera built in flash discharge method as default 1 = "discharge built in flash as master"
-then tried 2 = "discharge built in flash as controller flash"
flash on full power.
-neewer flash in s1 slave mode
In ether case neewer flash had no effect on the picture at full power. looks like flash didn't fire from the result. I watch it close and it does fire but is it late or early?
Just for fun tried the neewer flash on lowest power. At 1 it did show in picture. At 2 it showed in pictures. At 3 it showed in pictures. At 4 and up nothing same result as if the neewer was off.
What am i missing here.? Bad flash?
From what I can see, that flash does not appear to support P-TTL. Its a fully manual, single pin flash. The wireless flash options you are trying to use are for P-TTL wireless flashes. In order to use this flash wirelessly, you will have to trigger it with radio triggers (ideally) or using either optical dumb slave or smart slave.
S1 mode (dumb slave) means it will flash when it sees a flash. If you use the onboard pop-up flash to trigger it, you must use M mode so that there is no pre-flash. The P-TTL metering pre-flash will trigger the flash before the actual exposure.
S2 mode accounts for the P-TTL pre-flash by waiting after the pre-flash and then going off. You will need to use regular P-TTL on the pop-up flash. Using manual flash on the pop-up will make the Neewer go off too late.
