You need to look into this carefully. If the exposure is changing on its own in manual mode, then something is faulty and your k-x did in fact fail you.
If it's not faulty...well then you failed your k-x
. It's capable of much better. Things I'd suggest you look into-
1. What metering mode are you in? Spot?
2. Consider including the exif in the images you post, it will help in the trouble shooting.
3. IMO, forget any of the auto exposure modes, they are too unreliable in situations like this unless you know how to adjust the exposure bias to compensate for the scene you've framed. Manual exposure is your friend here ('course if your camera really is busted...).
4. When shooting in territory you aren't familiar with (like a sunny beach here), you should go beforehand and practice, practice, practice until you can get the results you will be happy with before bringing in the model with the tight schedule.
5. You should be able to manual focus in the bright sun using your viewfinder. Seriously, if you want to use manual focus lenses, you might want to practice this. Actually using the viewfinder as opposed to the lcd to compose is generally recommended when hand holding for a more stable platform.
6. A cheap reflector+ assistant will go a long way in the backlit situation you have here. Cheaper than a flash, easier for you to use than a flash (you can see the results of moving the reflector around), and no futzing about trying to stay within sync limits. (not that it can't be done with flash(es), just my vote is for a reflector in your case here for these reasons)
Good luck!
