were you connected to the lights via cable or using slave (triggered by pop up flash?)...sometimes the voltages triggering flash differ from camera make to camera make.
need to know what the set up was....

As above need to know more details. Obvious thing first. I take it, shutter speed was on or below the flash sync speed, or it wouldnt fire.

This does hinge on how the flash was to be triggered.
An IR or radio transmitter in the hotshoe is best, setting the camera to manual and choosing the flash synch speed and appropriate aperture.
If using the built in flash care need to be taken that any pre-flash is disabled, otherwise the flash will go off on the pre-flash and the shutter will fire after the event.

Thanks for trying to help. I emailed the tutor Glyn Dewis and we were using a Profoto trigger in the hot shoe of my K5. There were six other people on the workshop and they were using Nickons and Canons and had no problems with the trigger. This is not the first time it has happened because at camera club some setups work while others do not. I hope you can help me to solve this problem.

Not every trigger will work in every camera, even when they look identical. I think some triggers may not be very well made, so a slight mismatch and they are no good.
When we do group shots this can be a bit of a problem.

It does sound like the trigger isn't Pentax compatible.
It's also rare for a Nikon trigger to work on a Canon
and vice-versa, they are usually camera specific.

I've 2ce used my cactus V4 (non-specific) transmitter to fire the reciever (not 'my' reciever) of a set of studio lights at a camera club traning night... Just had to find the right channel...

Most of the manual triggers, can be non specific, as they only use the center firing pin to trigger. But you can get a situation with these where the pin is not in the centre of the hotshoe, over the contact. I loaned my trigger and recievers to our camera club this week, and it was working on various other brands of cameras, without any problems.

I think that is the most likely cause, I have some optical flash triggers that needed a little surgery to allow them to make contact

Is this possible with the K-5, John? If so, how is it done? If using the built in flash care need to be taken that any pre-flash is disabled, otherwise the flash will go off on the pre-flash and the shutter will fire after the event.

See page 191 of the K-5 manual. I've not tested this with studio flash as I use IR transmitters, but this may work and does work with 540 and 360 Pentax guns.

Hi
Thanks for the information. There were two set ups at the workshop one with a white background and a lady and I used s shutter speed of 125 at F11. The other one was a black background and a man and I used a shutter speed of 250 and F18. I thought the lights worked with the white background but maybe they did not.
and the other photo is
not sure whether this will work

The background light on the first one certainly fired, if the other lamps didn't fire she would certainly be in silhouette.
I think the second one is excellent.

I attended a workshop yesterday which was great, however my Pentax K5 did not trigger off the studio lights which was a shame. This has happened a couple of times on club portrait evening as well. Does any one know of how to solve this happening I had to use the tutor's second body which was a nickon
