Autofocus Problems

An attempt with autofocus

These beautifully camouflaged crabs where all over the beach this morning, and I though they would be easy to photograph with my telephoto lens (with macro feature). Well not exactly easy, because the translucent crab on sand gives little contrast for the autofocus to fix on and the camera was whirring away shifting the lens back and forth aimlessly. It was not until the crab crossed into my footprint that the camera had enough shadow contrast to focus properly.

better focus on footprint
