Ok. Thanks for the great info. I'm saving right now to buy new camera (though I have no Idea what should I buy) -- I'm also reading books and reading more threads here to have some ideas.
As you learn, you will be using the gear you have now. The more you learn, the more you will want to do. As you get better, you will find the limitations of your gear. Once you know exactly what your limitations are, you will know what cameras to look for that will limit you less. (all cameras from disposable $5 cameras to the $50,000 Phase Ones have limitations)
You will get there.
Heck, I am still in the beginning phase myself!!!!!!!!
