The most diverse composing options available in digital photography
Live View Function is a powerful feature on the EOS 40D. It enables viewing your subjects directly on the huge 3-inch LCD monitor. It's easy to magnify any part of the scene 5x or 10x for precise manual focus. But now, one press of the AF-on button gives instant access to AF; Live View Function returns as soon as the button is released. Users can even choose a grid overlay, perfect for keeping straight lines in your subject straight in your pictures. In the Studio, Live View Function can be used remotely via a computer through the EOS 40D's USB connection, or wirelessly or via Ethernet with the Wireless File Transmitter WFT-E3A attached. Live View Function also adds a totally new method for near-silent shooting, with two silent shooting modes. A new AF ON button, positioned for easy reach with the right thumb, can instantly allow AF whenever it's depressed in Live View Function. (Live View Function is temporarily cleared for AF, and returns immediately when the user's thumb is removed from the button.)
