JM,
You're no different than anyone else using a new digital camera. Most of us, except the professionals, use 25% of the features that an intermediate digital camera offers. I only use "auto" controls for outside family photos, for gun and parts photos, it's manual settings and a good tripod, and practice. My son and I bought a top notch tripod (~$90) a few years ago and that purchase was a "no brainer." They are universal and will fit most all digital cameras if you want detailed photos of guns and parts.
Photo taken from my workbench a year ago (Canon A620, three years old) on a tripod from 16" under florescent lights (alleged to be a big no-no but not true), manual settings. I am not a professional by any stretch but this photo would publish commercially easy. Use a neutral backgound that doesn't clash.
