Canon PowerShot SD110 Digital ELPH Camera


Introduction

The Canon PowerShot SD110 Digital ELPH is one of the newest members of Canon's popular, diminutive digital camera line. In both the film and digital worlds, the tiny, high-style Canon ELPH models have been wildly popular. Long a popular brand for APS film cameras, the Canon Digital ELPHs brought the compact size and styling to the digital world, beginning with the original PowerShot S100. The Canon PowerShot SD100 Digital ELPH updated the line by adopting the SD memory card format; now the Canon SD110 adds the Print/Share button, making a very popular gem of a camera a little easier to use with PictBridge printers. Because this is more of an internal upgrade, this review will echo much of my original SD100 review. If you're familiar with that model, you can save yourself some time by skipping most of the text here, jumping down to the Test Images section and proceeding from there.

Camera Overview

Slightly smaller than many preceding Canon Digital ELPH models, the PowerShot SD110 features the same great looks and sharp design that are the ELPH signature. Very compact and quick on the draw (thanks to a smooth retractable lens design), the PowerShot SD110 is a convenient point-and-shoot digital camera with a handful of extra exposure features for a little added flexibility. With the lens retracted, the Canon SD110's front panel is flat and pocket friendly, and its all-metal body rugged and durable. Equipped with a 3.2-megapixel CCD, the SD110 captures high quality images, suitable for printing snapshots as large as 8x10 inches. Smaller image sizes are also available for email transmission or Web applications, and a movie mode captures short video clips with sound.

The Canon SD110 features a 2x, 5.4-10.8mm zoom lens, equivalent to a 35-70mm zoom on a 35mm camera (a fairly common 2x zoom range). Aperture is automatically controlled, but the maximum setting ranges from f/2.8 at full wide angle to f/3.9 at full telephoto. A maximum 3.2x digital zoom option increases the SD110's zoom capability to 6.4x, but keep in mind that digital zoom decreases the overall image quality, as it simply crops out and enlarges the center pixels of the CCD image. Image details are thus likely to be softer with digital zoom. Focus ranges from 1.5 feet (47 centimeters) to infinity in normal AF mode, and from 3.9 inches to 1.5 feet (10 to 47 centimeters) in Macro mode. An Infinity fixed-focus mode is also available. The SD110 employs a sophisticated, nine-point AiAF (Artificial Intelligence Autofocus) system to determine focus, which uses a broad active area in the center of the image to calculate the focal distance (a feature I've been impressed with on many ELPH models and hope to see continued). Through the Record menu, you can turn AiAF off, which defaults the autofocus to the center of the frame. Also built-in to the SD110 is an AF assist light, which aids the focus mechanism in low light. For composing images, the SD110 offers a real-image optical viewfinder, as well as a 1.5-inch color LCD monitor. The LCD reports a fair amount of camera information, but excludes exposure information such as aperture and shutter speed. In Playback mode, a histogram display reports the tonal distribution of a captured image, useful in determining any over- or under-exposure.

Because the ELPH line capitalizes on ease of use, exposure control is typically automatic to increase the line's appeal to point-and-shoot users. The SD110 doesn't waver from this trend, but does provide a handful of manual adjustments, plus several enhancements to the PictBridge direct print functionality. Another enhancement, called QuickShot, allows users to take a very fast picture without having to wait for the camera to focus. The camera just switches to infinity and fires. The Mode dial on the rear panel controls the main operating mode, offering Playback, Auto, Manual, and Movie modes. Shutter speeds range from 1/1,500 to 15 seconds, with the one- to 15-second end of the range only available in Long Shutter mode (which also automatically invokes a Noise Reduction system to eliminate excess image noise in longer exposures). In straight Auto mode, the camera controls everything about the exposure except for file size, flash, etc. Manual mode provides more hands-on control, with White Balance, Exposure Compensation, ISO, and some creative effects. Camera operation is straightforward, as you typically just point and shoot most of the time. Pressing the Shutter button halfway sets focus and exposure, and the small LEDs next to the optical viewfinder let you know when the camera is ready to take the picture.

The SD110 uses an Evaluative metering system by default, which means that the camera divides the image area into zones and evaluates each zone to determine the best overall exposure. A Spot metering option ties the exposure to the very center of the frame, and is useful for off-center or high contrast subjects, letting you pinpoint the exact area of the frame to base the exposure on. There's also a Center-Weighted metering option, which bases the exposure on a large area in the center of the frame. Exposure Compensation increases or decreases the overall exposure from -2 to +2 exposure equivalents (EV) in one-third step increments. A White Balance option offers Auto, Daylight, Cloudy, Tungsten, Fluorescent, Fluorescent H, and Custom (manual) settings. The SD110 also offers a creative Photo Effects menu, which adjusts sharpening, color, and saturation. Sensitivity equivalents include 50, 100, 200, and 400 ISO settings, as well as an Auto adjustment. The SD110's built-in flash operates in Auto, Forced On, Suppressed, Red-Eye Reduction, and Slow-Synchro modes. You can also lock the flash exposure in the same way you can lock normal exposure. Pressing the Shutter button halfway and keeping it pressed initiates the exposure lock, signaled by two beeps and activating an "FEL" icon in the LCD monitor until the Shutter button is released or fully pressed.

A two- or 10-second self-timer option counts down by flashing a small LED on the front of the camera before firing the shutter, giving you time to duck around the camera and get into your own shots. Stitch-Assist mode is the SD110's panoramic shooting mode, which lets you shoot as many as 26 consecutive images. The series of images can then be "stitched" together into a single panoramic frame with the accompanying software. The SD110 also has a Movie Record mode, which records moving images with sound for as long as three minutes per clip, depending on the resolution setting and amount of memory card space. (Movies are recorded at either 640 x 480, 320 x 240, or 160 x 120 pixels.) Finally, a Continuous Shooting mode captures a series of consecutive images (much like a motor drive on a traditional camera), at approximately 2.2 frames per second, for as long as the Shutter button is held down. The actual frame rate varies with the resolution setting, with the total number of images also depending on the amount of memory card space and file size.

The My Camera settings menu lets you customize camera settings to a specific theme. Everything from the startup image to operating sounds can be assigned to a theme, either one of the pre-programmed themes or one downloaded from the camera software or stored on the memory card. The SD110 also lets you record short sound clips to accompany captured images, via the Sound Memo option, great for lively captions to vacation photos or party shots.

The SD110 stores images on SD memory cards (hence, the "SD" in its name). A 16MB card accompanies the camera, but I recommend picking up a larger capacity card, at least 64 megabytes, so you don't miss any shots. The camera utilizes a rechargeable lithium-ion battery pack for power, which accompanies the camera, along with the necessary battery charger. Because the SD110 does not accommodate AA-type batteries in any form, I strongly advise picking up an additional battery pack and keeping it freshly charged. The optional AC adapter is useful for preserving battery power when reviewing and downloading images, and actually uses a "dummy" battery that inserts into the camera's battery compartment. A USB cable and interface software are also packaged with the camera, for downloading images to a computer and performing minor organization and corrections. Two software CDs provide the necessary drivers and editing software, both compatible with Windows and Macintosh platforms. One CD holds Canon's Digital Camera Solution Disk version 12.0 and the other features ArcSoft's Camera Suite version 1.2. Finally, an A/V cable connects the SD110 to a television set, for reviewing and composing images. The SD110 is Digital Print Order Format (DPOF) compatible, with detailed print settings in the Playback menu. Canon offers a selection of direct-connect printers as well, which simplifies printing even more.
