Hello and welcome Meg - good choice.
Welcome. How do you plan on using the G2?
What kind of images are you seeing?
The G2 is a very versatile camera and it would help if we know those 2 answers.
Welcome Meg and congratulations on your G2! Believe it or not, you will get a handle on how the camera works, though I know at first it can be overwhelming. If you haven't yet, I'd suggest you take a look at the Panasonic forum where you'll find a lot of people who'll be glad to help. I'm sure Don (Streetshooter) will get back to you here, too.
Although I'm not familiar with the G2, I posted a sticky at the top of the page in the Panasonic forum that links to Panasonic's website... I just took a look and found this: Panasonic DMC-G2K Support and Service Information Perhaps it will be of some help? Meanwhile, please do not hesitate to start a new thread on the Panasonic Camera forum, Meg. The members here are great and usually extremely helpful.
