Allright, im a complete beginner, with a beginner's kit. I have a kodak dx 7630 (6.1 mp, 3x optical). There are some things that arent completely manual with this camera, like the depth of field. its always sorta small, like the middle of the screen, even though i tried different focus settings. I dont have enough money to go for a nice camera, or any other camera really. I'd just like some suggestions on if i should just press on with this or look at some add on lenses or what.
