I am looking to buy a camera that excels in taking high quality macro pictures, the higher the quality of the zoom and picture the better, I would take pictures of the DNA of whatever it is I'm photographing if I could.
My budget goes as far as 500 pounds.
I am very new to this but am eager to learn every single feature of the camera I choose to buy though I need to be directed to one first.

Thank you for your time.
