I am extremely excited about my new Sigma 50mm F2.8 DG Macro lens arriving today. Out of the box and onto the camera, I quickly found myself eager to start shooting. The lens is used and didn't come with a user guide, though it seems fairly straight forward. What are some tips and hints to shooting good quality macro shots? I quickly understood the simplicity of shooting in direct sunlight with a faster shutter speed. I also see the need for a small tri-pod for the shots on the ground (insects, flowers, etc.) For a complete beginner to macro photography, what can you share with me to make me better at perfecting this delicate craft?
