I really enjoy using the Sony Eye- AF feature. Allows me to concentrate on the composition. No need to worry if the eyes in your portrait photography will be sharp. You can achieve pictures of people with razor sharp eyes. That's what I love about Sony products, the technology is advanced, but it does not get in the way of your creativity. It in fact, it inspires you and helps you be more creative.
