Megapixels get too much emphasis these days. Most people really don't need more than 6 megapixels to take nice stills that you can edit, crop, post to the Web, or even print out to a respectable size. Larger images can be more trouble than they're worth for casual users, since larger file sizes require more memory and computer power to store, process and edit. That said, higher resolutions can be handy. The more pixels you have in an image, the more you can zoom in and look at fine details, and the larger you can blow up prints. What does this mean for you? Don't get sucked into the megapixel hype, and don't sacrifice image quality or performance just for a few more pixels.
The Casio Exilim EX-Z1200 joins the slowly growing ranks of 12-megapixel compact cameras. Like the Panasonic Lumix DMC-FX100 and the , it packs a 12-megapixel sensor into a portable, relatively pocketable package.
At 6.4 ounces with battery and SD card, the Z1200 weighs in as one of the heaviest Casio Exilim cameras to date. Despite its relative heft, the Z1200 cuts a similar profile to other Exilim Zoom cameras. Its body measures just 0.9 inch across, making it slim enough to fit into a shirt or jacket pocket. A 2.8-inch LCD dominates the camera's back panel and dwarfs the screens of many other compact cameras.
Unfortunately, the combination of small body and large screen leave the Z1200 with precious little room for controls. The camera's joypad and buttons feel small and cramped, and can confound large-thumbed users. While its physical buttons can seem awkward, the camera's software interface works quite well, revolving around an on-screen sidebar that offers direct and intuitive access to nearly every camera setting.
Besides its 12-megapixel sensor, the Z1200 packs plenty of advanced features. A mechanical image stabilization system physically shifts the CCD while shooting to reduce blur and shake. Like an increasing number of snapshot cameras, the Z1200 also offers a face-detection mode when framing shots of people. Most cameras with face detection simply recognize all faces as faces; the camera sees what it recognizes as a face, and it adjusts focus and exposure accordingly. If you have a lot of different people in the frame and want the camera to focus on only people you know, you can record their faces in the camera's memory. While the feature is only useful in certain limited situations, it offers a new twist on the increasingly standard face-detection feature.
The Z1200 offers aperture priority, shutter priority, and manual exposure modes for more experienced users. These exposure controls are handy if you want more control over your shots, but they're hardly perfect; the camera's lens can only toggle between the widest and narrowest aperture settings; you can't select a middle ground when in aperture priority or manual modes. At the widest angle of the lens, you must choose between F/2.8 and F/8.0, and at the narrowest angle you must choose either F/5.4 or F/15.4. If you don't want to deal with manual controls, the Z1200 also includes an automatic snapshot mode and 34 of Casio's Best Shot scene presets.
