Justin welcome aboard.
When I went from fixed lense digicams to a DSLR I found my love of the outdoors increased as I am outside more now than ever.
You are going to enjoy your new camera as it is a very good semi-pro camera. Just looking at pictures on the web show the K10D to be more than capable for the majority of users. I use the older istDs and love the size of the camera, but it in no way has the incredible feature set of your new K10D.
Looking forward to your posts.
