Olympus E-420 Review
Live View off: Shooting information / settings changes
With live view off you can optionally display a Control Panel on the LCD monitor, this provides both an overview of camera settings as well as a method for changing settings. Press OK to access the options, move around and press OK again to change a setting.

Live View on
Like the E-410 the E-420 utilizes the main sensor for its live view mode. To activate it you simply press the live view button on the rear of the camera. You can change the image overlay in live view mode by pressing the INFO button. Below you can see the four default views followed by the three optional grid overlay views and the new comparison screen for exposure compensation and white balance preview.
This works generally very well but the some functionality of buttons changes in different live view modes. This can be slightly confusing, at least while the camera is new to you.
Changing settings in Live View
In live view mode pressing the OK button displays a semi-transparent settings overlay as shown on the left below, this not only provides a summary of current camera settings but allows you to navigate and change any setting you wish.
Live view AF video clips
The E-420 offers three AF modes in Live View. In 'AF Sensor' mode the E-420 (like the E-410) focuses in Live View by closing the shutter and dropping the mirror so that the AF sensor can be used. During AF the Live View is darkened and frozen and returns when the camera has achieved a focus lock or has given up trying, this can take between 0.7 seconds (good light easy subject) and 4.0 seconds (to give up when it can't lock).
in the new 'Imager AF' mode the camera focuses by using contrast detection on the imaging sensor (just like a digital compact camera). You can choose one of eleven AF areas (as opposed to only three when using the camera's AF sensor). Please note that only a limited number of lenses is currently compatible with this AF mode.
Your third option is the also new 'Hybrid AF' mode. This mode combines the two AF methods described above. When you half-press the shutter button the camera focuses approximately using contrast detection. If you now press the shutter button down all the way the camera fine tunes the focus using the AF sensors. This mode is useful if you want to use the Imager AF mode with a lens that is not compatible with this mode.
Below you will find four short video clips demonstrating the various ways of using Auto Focus in Live View.
AF Mode: AF Sensor (shutter release press)
The video below shows live view with the 'AF Sensor' (passive) AF mode, the shutter release is half-pressed and shortly after fully depressed. Note that in this mode the camera does not auto-focus with a shutter release half-press (see next video).
AF Mode: AF Sensor (AF/AE button then shutter release press)
This video is using the same AF mode as above but instead of just a half-press of the shutter release button we are pressing the AF/AE button first (which causes the camera to auto focus) followed by a shutter release depression.
AF Mode: Hybrid AF (shutter release press)
The video below shows live view with the 'Hybrid AF' (contrast detect + passive) AF mode. Here the half-press of the shutter release triggers auto-focus using the imaging sensor (contrast detect) which can be useful for previewing the focus position however the final shutter release 'full press' still uses the normal AF sensor (passive) to focus just before the exposure.
AF Mode: Imager AF (shutter release press)
The video below shows live view with the 'Imager AF' (contrast detect) AF mode. Here, as above, a half-press of the shutter release triggers auto-focus using the imaging sensor (contrast detect) but the final full press does not use the AF sensor but instead simply triggers shutter release (as per a typical compact digital camera).
Live View magnification
The E-420 features magnified Live View in all focus modes, simply press the INFO button until the magnify loupe appears. You can reposition the loupe anywhere in the scene then press OK to magnify. Select between 7x and 10x view by turning the main dial.

Live View: Low Light performance
The E-420's low light performance is fairly good and dark scenes are perfectly viewable. However, pushing things to their extreme (a dark scene plus very small aperture DOF preview) will cause the image to turn monochrome and noise to appear.

Live View: Depth of Field preview
One advantage of Live View is that you can get an exact representation of focus point and depth of field on the LCD screen. In the example below the image on the left is at F5.6, on the right at F22 with the DOF preview button held (this is a custom option). As you can see our scene was not lit brightly enough and the image turned monochrome when using using DOF preview at a small aperture.
