Originally posted by R. Glasgow Hi Adam again. I still have no answers to my problem or no replies to my first query. Perhaps I will simplify my query!!
My new flash gun AF-540 FGZ (Pentax) only ever registers 'Leading Curtain Sync' on the LCD display no matter what position I move the SYNC switch to! Is this a faulty SYNC switch or why can I not select other options such as HSS?
There is no 'click' when I move the switch other than at both extremes R+L of the choices!
Can anyone (Pentax Please) confirm if this flash will work with the K5 camera in all SYNC modes?
Many thanks.
That slider is just plain awful. It is very difficult to tell if it is in either of the center modes.
Then, when it is, the display may not show it. The camera often must be metering in order to show the mode it is in.
Otherwise it will just read |> for default leading curtain sync.
Regardless, the HSS mode is far right, so it should be easy to tell if that is where you landed.
If that isn't working, be sure your flash is seated securely.
If you have a zoom lens, try with that. You should at least hear the flash zoom in and out.
If that works, but HSS still does not, you can be pretty sure that the flash is having a problem.
Could be the camera I suppose, but if zoom works I would not suspect the camera for the HSS issue.
I assume by a higher flash speed than 1/180 you mean shutter speed... but try the camera in manual to Tv mode, and set the speed higher then 1/180. The camera will be forced to allow more then 1/180 but will refuse to fire the flash unless it is in HSS mode.
The camera is not in green mode, is it? My flash is not with me at the moment so I cannot verify, but I thought I recall sue issue with green mode not allowing that feature, or some other limitation...
Just to add.. and yes, this flash most certainly works in all modes with the K5.
Although I really have no idea what the contrast sync does or how to verify if it works. It just sounds like a very seldom used feature and one I have no interest in anyway.
But; Leading, Trailing and HighSpeed syncs all do work.
