Viewfinder
The Casio Exilim EX-FH20's electronic viewfinder uses a 0.2-inch LCD with 201,600 equivalent dot resolution. Pressing the button to the viewfinder's left will display all menus and data overlays through the viewfinder.

If you want the screen's display to appear in the viewfinder, you'll
have to hit the button to the viewfinder's left.
LCD Screen
The LCD screen is 3 inches diagonally and contains a standard 230,400 pixels. We thought the screen was slightly laggy and slower to refresh than we'd expect, but the unit is pre-production and a sub-par refresh rate is likely to be addressed before the product hits shelves.

Hopefully the display will be slightly more fluid on the final product.
Flash
By pressing the little lightning bolt-branded button on the camera's left side, you'll summon the camera's pop-up flash. The benefit to having a pop-up flash, versus the common compact camera flash position on the camera body itself, is that the source of light is further away from the lens, which helps to minimize red-eye.

Most point-and-shoot cameras do not feature a pop-up lens like this.
Lens
The EX-FH20 has a focal range of 26-520mm and an aperture range of f/2.8 - f/4.5. The lens has a 20x optical zoom and a 4x digital zoom. The camera uses sensor shift image stabilization.

Between optical and digital, the Casio Exilim EX-FH20 is
capable of an 80x zoom, although digital zoom severely
degrades picture quality.
Connections
The camera has two proprietary ports, one for power and one for a USB connection. The previous version, Casio's Exilim EX-F1, had a mini HDMI out, AV output, and an external microphone jack, none of which made it onto the EX-FH20.
The number of ports has been greatly reduced in the jump from
EX-F1 to EX-FH20.
Battery
The EX-FH20 takes four AA batteries, widely available wherever one travels in the world.
Holy moley, who stole the batteries?
Memory
The Casio Exilim EX-FH20 accepts SD and SDHC cards. It also has 31.9MB of on-board flash memory.

SD and SDHC support allows the user a wide range of
options for memory expansion.
Other Features
High burst mode rate – The Casio Exilim EX-FH20 is capable of capturing 7-megapixel photos at a rate of up to 40 per second. We actually timed this by taking photos of a stopwatch and found the 40fps claim is true to within a tenth of a second. To enable this high frame capture rate, first turn on a continuous shot capture mode with the control dial. Then hold down the shutter button for a second or less. Once you've taken your photos, you can opt to save all, a selected few, or toss them all out.
High-speed video capture - The EX-FH20 is capable of capturing videos at the following resolutions and frame rates: 1280 x 720 at 30 fps, 640 x 480 at 30 fps, 320 x 240 at 30 fps, and 224 x 168 at 420 fps. Fo the ultimate in high-speed capture, though, you'll have to settle for the postage stamp-sized 224 x 56 resolution, which can be captured at a 1000 fps.
