Well, I use M Mode most of the time. However, my wife and my mother in law use P mode and AUTO mode most of the time to take pictures of twins. They say it is easier for them since they simply want to take pictures of children only.
Please be advised, remember to turn off the flash when taking pictures of children under age of 3 (according to eye doctors, human eyes won't be mature enough until age of 5)
By the way, there are tons of modes available in EX1. Please do explore them and take a few shots, I find it is super fun to use creative modes.
Ever since I bought this camara, I never complain anything except it is kindda slow to store pictures in my Sandisk Ultra Class 4 memory card. I say it is kindda slow is based upon comparison to my Canon 550D.
People ask me why buy EX1 when I already have 550D and Sony T700? Well, my wife hates 550d for its boggy size and weight. Sony T700 simply sucks big time taking pictures indoors without flash. My mother in law lives with us to take care one of the twins and her birthday is after my twins. hahaha, so, I bought this camara for my mother in law and she likes to use EX1 to take pictures of her twin sons. So, I guess EX1 is a good deal after all for me and my wife. hahaha.
From what I have experienced with my EX1, I do believe it is a great buy for me and my family. Afterall, my twin sons will only grow up once, right? hahaha
