Yes, the switch is where it should be - it's one of the things I checked!

1/180 is the sync speed.
I haven't checked the program line, but as the flash shows the same malfunctions on two different cameras on which it had previously worked correctly I don't think this could be the problem.

I do use the flash with the camera in manual mode, usually as a fill-in ... or I did but it's no longer working reliably. I tend to use "P" when using flash as the main light source, and it's worked OK for about 6 years on 3 different cameras, hence why I think the flash has developed a fault!

But thanks for your suggestions!

I am having problems with my AF 360 flash - in essence it used to work properly and now it doesn't. Originally it would, when the camera was set to "P" mode, set the shutter speed to 1/180 and expose images properly. Now it seems to set the shutter speed to 1/90 and successful exposure is a matter of luck.

I've checked settings, including re-reading the manual, but nothing seems to help. Tried it on my other camera in case it was the body that was defective, but it made no difference.

Has anybody else encountered similar problems, and if so, is there a fix or is the flash unit effectively dead?

For info I'm using a K5, the flash worked OK on this, the K20D that preceded it and also the *ist DS that I had when I bought the flash.

Many thanks!
