Thanks again John, I had a closer look after I had posted my reply and found memory.

Thanks for the info, I will get spare battery asap, I assume to save, you just click OK when time etc is entered. as I can't find any "save" in menu. Another thing is, I bought a 32gb card hoping to get a good length of video time, I can get 10000 photos but only 10 mins video. Is this usual ? Once again thanks very much for info John, snappychappy I wish I could take photos a fractionas good as you.

I have recently bought a Pentax Optio RX18, do I have to re-enter date etc every time I charge battery. ?
