Viewfinder

The C-4000 Zoom offers both a real-image optical viewfinder and a rear panel, 1.8-inch, 114,000 pixel, TFT color LCD screen. The optical viewfinder accommodates eyeglass wearers with a diopter correction adjustment and a comfortably high eyepoint, leaving a reasonable amount of room between your eye and the finder for an eyeglass lens to fit. Although the optical viewfinder zooms along with the lens, it does not show the operation of the digital zoom, which can only be enabled when the LCD monitor is on. A set of four lines in the center of the field of view mark the autofocus area, and help you center your subjects. Two LED indicators (one orange and one green) are adjacent to the viewfinder window, indicating camera status with either glowing or blinking lights. If the green LED blinks, the camera is either having trouble focusing, or there's a problem with the SmartMedia card. A solid green LED indicates that focus is set and the camera is ready to snap the picture. A flashing orange LED means that the flash is still charging or there is a potential of camera shake, while a solid orange LED shows that the flash is fully charged and ready to fire.

The C-4000 Zoom's LCD monitor provides detailed information about a number of exposure settings, including the currently selected f/stop, shutter speed, and exposure compensation adjustments across the top of the screen. In Aperture and Shutter Priority modes, the chosen aperture or shutter speed appears as a manually-set constant, while the second, automatically determined exposure value updates continuously in response to scene lighting and the exposure compensation setting. In Manual mode, the camera displays both the selected f/stop and shutter speed values (adjustable with the left / right and up / down Arrow buttons, respectively), while the exposure compensation readout serves as an exposure display, showing the amount the camera thinks your settings will over- or underexpose the subject. (The exposure display turns red if your chosen exposure is more than 3 EV units away from what the camera calculates to be correct.)

The C-4000 Zoom also offers a "live" histogram display, which automatically appears in the LCD display in any automatic exposure mode (that is, in Program, Aperture, or Shutter Priority exposure modes), when enabled through the LCD menu. The histogram gives you an idea of how over- or underexposed the captured image is, by graphing the tonal distribution from highlights to shadows. You can also view the histogram in Playback mode, along with the exposure information for each previously-captured image.

When using the LCD monitor to review captured images, you can zoom in on displayed images up to 4x, and then scroll around the enlarged image using the Arrow buttons. This is very handy for checking focus, small details, or precise framing. There's also an Index display option, which shows either four, nine, or 16 thumbnail images at a time. A very handy "Quick View" function also lets you switch quickly from shooting to playback mode by pressing the Display button twice in rapid succession. The camera will display the most recently captured image on the LCD screen, but you have essentially all of the playback-mode options available to you, and can scroll back and forth to other images, zoom in and out on them, and call up the information display. You can revert to shooting mode either by pressing the Display button again, or simply by half-pressing the shutter button.

A Record View function, enabled through the Shooting menu (Setup sub-menu), displays the most recently captured image on the LCD screen while the image is being recorded to the memory card. This feature gives you the option of deleting an image instantly by pressing the Flash / Delete button while the review image is still onscreen. It's a great way to check your images without spending time switching back and forth between Playback and Shooting modes.
