3.2-megapixel CCD
Point and Shoot Camera
May 2003

The Sony Cyber-shot DSC-P72 maintains similar dimensions and design as the rest of the Cyber-shot mid-sized "P" series, making it portable and compact. It's small enough to fit most shirt pockets, and a wrist strap keeps it securely attached to your wrist when shooting. The compact design includes a shutter-like, built-in lens cover which conveniently slides open whenever the camera is powered on, allowing the lens to telescope outward about 3/4-inch from the body. The DSC-P72's 3x zoom lens features automatic focus control, with several fixed focus settings available and an adjustable focus area. The 3.2-megapixel CCD produces high resolution, print quality images, as well as lower resolution images suitable for e-mail or other electronic use. Combine this with the ease of automatic exposure control, a handful of preset "scene" modes, and the creative Picture Effects menu, and the DSC-P72 is an excellent choice for novice consumers who want to take great pictures without hassling with exposure decisions.

The DSC-P72 is equipped with a 3x, 6-18mm lens, equivalent to a 39-117mm lens on a 35mm camera. This is a fairly typical range, slightly biased toward the telephoto end relative to the more common 35-105mm range found on many 3x zoom-equipped cameras. Normal focus ranges from approximately 1.64 feet (0.5 meters) to infinity, with a Macro (close-up) setting that lets you get within four inches (10 centimeters) when the lens is zoomed to its wide angle position, and 19.75 inches (50 centimeters) at its telephoto setting. (The net result is about average performance in closeup shooting.) In addition to automatic focus control, the DSC-P72 offers a total of five fixed focus settings through the Record menu, as well as Center AF and Multi AF focus area options.

An AF illuminator lamp on the front of the camera helps focus at low light levels, a very handy feature. The DSC-P72 employs a new technology that Sony calls "Smart Zoom," which offers a maximum of 3.2x digital zoom. According to Sony, Smart Zoom lets you digitally enlarge the image without any significant loss of image quality. In actuality, "Smart Zoom" simply means that the camera doesn't interpolate the pixels it crops from the center of the CCD array when zooming digitally. This limits the digital zoom range based on the currently-selected image size, with maximum zoom only available at the smallest image size. This is the most reasonable approach to "digital zoom". For composing images, the DSC-P72 offers a real-image optical viewfinder and a 1.5-inch, color LCD monitor.

Exposure is automatically controlled at all times on the DSC-P72, great for novices and casual users looking for simplicity. You can override the exposure with an exposure compensation adjustment though, a necessary feature for shooting subjects that are uniformly light or dark overall. 

An On/Off button on top of the camera powers the camera on, and a Mode dial on the back panel selects between Playback, Record, and Movie exposure modes. Within Record mode, you can select Automatic, Program, Twilight, Twilight Portrait, Landscape, Snow, or Beach modes. The Automatic setting removes all user control, with the exception of flash, macro, and resolution. Program mode keeps exposure determination automatic, but you now have control over all other exposure variables. Both Twilight modes optimize the camera for low-light shooting by allowing shutter times as long as two seconds, while Landscape mode sets the camera up for shooting broad vistas. Snow mode enhances saturation to prevent loss of color in bright white snowscapes, while Beach mode ensures that blue tones are recorded accurately in lakeside or seaside photos.

Although the camera controls aperture and shutter speed, it does report the settings it has chosen on the LCD information display, so you have an idea of what the exposure will be. Knowing the actual shutter speed can be very helpful in judging whether or not you'll be able to successfully hand hold an exposure in dim lighting. The Record menu offers additional exposure options of White Balance, Exposure Compensation, Spot Metering, ISO, Record Mode, Flash Level, Picture Effects, Focus, and image quality settings. Under the Picture Effects setting, you can record images in black and white or sepia monochrome, or select the Solarize or Negative Art options. 

The DSC-P72's flash operates in Forced, Suppressed, Auto, Red-Eye Reduction, and Slow-Sync (Twilight Portrait only) modes. Interestingly enough, Sony removed the image size setting from the Record menu, and gave it an external control. This is useful when trying to quickly change resolution settings, as you don't have to fish through menu options. (Though you'll still need to call up the menu system to adjust the image quality setting.)

In Movie exposure mode, the camera captures either 640 x 480-, or 160 x 112-pixel resolution moving images with sound for as long as the memory card has available storage space. Unrestricted (other than by card capacity) recording at 640 x 480 pixels is quite unusual in digicams, and is the key feature that distinguishes Sony's MPEGmovieVX mode. The DSC-P72 also offers Clip Motion and Multi Burst modes. Clip Motion records a series of up to 10 images that are automatically saved in a single animated GIF file, and that can be played back as an animation sequence. Multi Burst mode captures an extremely rapid 16-frame burst of low-resolution images, at a selectable rate of 7.5, 15, or 30 frames per second. Multi Burst shots are played back as a slow-motion animation on the camera, but appear as a single large file with 16 sub-images in it when viewed on a computer. A Self-Timer mode provides a 10-second delay between the time the Shutter button is pressed and the time that the camera actually takes the picture, giving the photographer time to run around and get into the picture. Also available on the DSC-P72 are Burst 2 and Voice record modes. Burst 2 records two images in rapid succession, with one press of the Shutter button. Voice mode records a short sound clip to accompany an image, useful for attaching voice captions.

The DSC-P72 stores images on Sony Memory Sticks, available separately in capacities as large as one gigabyte. (The DSC-P72 is compatible with Sony's new Memory Stick PRO format, breaking the previous 128 MB barrier for Memory Stick storage.) A 16MB Memory Stick comes with the camera. As with last year's mid-sized P-series models, the P72 once again departs from Sony's typical practice of using their proprietary "InfoLITHIUM" batteries, using instead two AA batteries for power, either alkaline, NiMH, or lithium. A set of two rechargeable NiMH AAs and a battery charger are included in the box with each camera. Battery life is quite good for a two-AA cell camera, but still,  pick up a couple of extra sets of rechargeable AA batteries and pack them along on any extended outing. 

The optional AC adapter is useful for preserving battery power when reviewing and downloading images, but having a couple of sets of rechargeable batteries really eliminates the need for it apart from extended studio use. The DSC-P72 features a Video Out jack, for connecting to a television set, and a USB jack for downloading images to a computer. A software CD is loaded with Pixela Image Mixer software and USB drivers, for downloading and organizing images. (On Windows Me, 2000, or XP computers, or Macs running OS 8.6 to 9.2, no separate USB driver software is needed. The camera shows up on the desktop automatically when it is plugged in.)

Like the rest of the mid-sized "P" series of Sony Cyber-shot cameras, the DSC-P72 is a good quality, compact digicam. It offers the convenience of point-and-shoot simplicity, but with enough advanced features to make it possible to take photos in otherwise challenging situations (low light, fast action, etc.). The 3.2-megapixel CCD delivers high quality images, appropriate for any use from printing to distributing via e-mail, and its compact design makes it a good candidate for travel. (While not as tiny as cameras like Sony's own P8 and P9, or the Canon Digital ELPH series, the P72 fits quite nicely into pant or coat pockets.) Overall, the P72 is a good choice for anyone wanting a capable, portable camera that takes good photos in a variety of circumstances. The DSC-P72 is easy to use for beginners, but has enough flexibility to handle a range of conditions.

Design
With its small body size and compact design, the DSC-P72 maintains dimensions similar to the rest of Sony's midsized "P" series Cyber-shot models. Its sleek, smooth styling is free from any significant protrusions except for the lens, which telescopes outward when powered on. The DSC-P72's dimensions of 4.75 x 2.38 x 1.31 inches (120 x 58 x 33 millimeters) makes it just small enough to fit into a shirt pocket or small purse. The all-plastic body keeps the DSC-P72 light weight as well, at just 9.1 ounces (258.6 grams) with batteries and memory card.

FRONT VIEW

The front of the DSC-P72 is rounded on the right side, following the shape of the lens barrel and adding to the smooth design aesthetic. A shutter-like, retractable lens cover protects the lens whenever the camera is powered off, flipping quickly out of the way when the camera is turned on again. The lens telescopes out from the camera body about 3/4-inch into its operating position. Also on the front panel are the flash, optical viewfinder window, AF illuminator lamp, and small microphone. A small, sculpted ridge serves as a finger rest when holding the camera, improving your grip to a surprising degree. Still, this ridge is small enough that you'll probably want to keep the wrist strap securely in place while shooting.

Battery Compartment

On the right side of the camera (as viewed from the back) is the battery compartment. A sliding plastic door protects the compartment, and features a latch that prevents it from accidentally flying open while shooting. Just below the compartment is the wrist strap attachment eyelet.

Memory Stick Slot

The opposite side of the camera features only the Memory Stick compartment, at the very bottom. A hinged, plastic door opens downward to reveal the card slot.

TOP VIEW

The DSC-P72's top panel is fairly smooth and flat, featuring only the Shutter and Power buttons, both of which barely protrude from the camera's surface.

BACK VIEW

The few remaining camera controls are on the back panel, along with the optical viewfinder eyepiece, LCD monitor, speaker, and connector jacks. Three LED lamps next to the optical viewfinder report camera status, indicating when focus is set or the flash is charging. The Mode dial and Zoom rocker button dominate the top left corner of the back panel, while the Menu, Display, Image Size / Erase, and Four Way Arrow pad line up below them. A small speaker is on the left side of the LCD monitor. On the right side, beneath the Zoom rocker button, a tethered plastic flap covers the DC In, Video Out, and USB connector jacks. Two ridges on the outside of the plastic flap serve as a thumb grip while holding the camera.

BOTTOM VIEW

Camera Operation
The DSC-P72's user interface is very straightforward, with only a few external controls and a very concise LCD menu system. Menu setup is similar to previous Cyber-shot designs, though the DSC-P72 does have a couple of changes relative to prior units. For starters, all of the camera's scene and exposure modes are now accessible through the Record menu, and the mode selection dictates the available menu options. (Previous models employed a separate mode dial position for Scene mode access.) Sony also moved the resolution setting to an external control, for quicker access. For standard point-and-shoot operation, the most basic features (flash, zoom, and macro and self-timer modes) have external controls, while settings like White Balance, Exposure Compensation, etc. are adjusted through the menu system. The Mode dial lets you quickly set the camera's main operating mode, with just a turn. When you do need to enter the LCD menu system, you'll find it simple to navigate, with each setting appearing as a separate tab at the bottom of the screen. The arrow keys of the Four Way Arrow pad scroll through the selections, and the OK button in the center of the pad confirms any changes. The menu system is so simple and intuitive even novice users will be able to become completely familiar with it in an hour or less.

Record-Mode Display
In record mode, the LCD monitor optionally displays just the subject, the subject plus an information overlay, or nothing at all. (That is, the LCD may be turned off.)


Playback-Mode Display
In playback mode, the LCD display can show the captured images with or without an information overlay, a thumbnail index showing multiple images at once, or detailed information regarding the exposure parameters for a given image. The index and detailed information displays are accessed by pressing the "W" side of the zoom control on the camera's rear panel. Pressing the "T" side of the same control lets you zoom in on an image, up to 5x. Once zoomed, the arrow keys let you scroll around the enlarged image.

External Controls

• Playback: Replays captured still images and movie files, with options for image management and printing.
• Record: Places the camera in Record mode, with seven exposure modes available.
• Movie: Records moving images with sound, for as long as the Memory Stick has space. Also accesses Clip Motion and Multi Burst modes when activated through the Set-Up menu.
• Set-Up: Displays the Set-Up menu, for changing camera settings.

In Playback mode, this button controls the digital enlargement of captured images and accesses the index display mode as well as a detailed information display. (The "T" side zooms in, the "W" side zooms out. Zooming out from the normal-sized single image view brings up an index display of tiny "thumbnail" images.)

In Automatic Record mode, the up arrow controls flash mode, cycling through Auto, Forced, and Suppressed modes (it only activates Slow-Sync in Twilight Portrait mode, and no flash modes are available in Twilight, Landscape, or Movie modes). The down arrow activates the Self-Timer option, while the right arrow controls the Macro mode (close-up). The left arrow calls up a quick review of the most recently-captured image.

In Playback mode, the left and right keys scroll through captured images on the memory card. When an image has been enlarged, all four arrow keys move around within the enlarged view.

• Camera: This menu takes the place of several mode-dial options on previous Sony models. Offers Automatic, Program, Twilight, Twilight Portrait, Landscape, Snow, and Beach exposure modes. The mode selected dictates which of the following options are available. (Program mode offers all of the following, Auto offers only the Mode submenu.)
• Exposure Compensation: Increases or decreases exposure from -2 to +2 exposure equivalents (EV) in one-third step increments.
• Focus: Changes the focus area to Multi AF or Center AF, or selects from a range of fixed focus settings (0.5, 1.0, 3.0, or 7.0 meters, or Infinity).
• Spot Metering: Selects between Spot Metering or Multi Metering mode.
• White Balance: Sets the color balance to Auto, or adjusts for Daylight, Cloudy, Fluorescent, or Incandescent light sources.
• ISO: Sets the camera's light sensitivity to Auto, or to 100, 200, or 400 ISO equivalents. Use ISO 200 or 400 for action shots, where you need a faster shutter speed to freeze the action. (Higher ISOs produce "noisier" images though.)
• Image Quality: Sets the JPEG compression level to Fine or Standard.
• Mode: Changes the recording mode to Normal, Voice, Burst 2, or E-Mail (records a 320 x 240-pixel image in addition to one at the selected image size). Voice records a short sound clip in addition to the JPEG image. Burst 2 mode records two images in rapid succession, with one press of the Shutter button.

Recommended Software:
Just as important as an extra memory card is a tool to rescue your images when one of your cards fails at some point in the future. Have you lost photos due to a corrupted memory card? Memory card corruption can happen with any card type and any camera manufacturer. A surprising number of "lost" images can be recovered with easy to use software.

Batteries
Alkaline AA batteries are not recommended for use in a digital camera. Despite their being packed in the box with many cameras, they simply don't have the stamina to handle typical digicam demands. Sony includes a very high capacity set of AA NiMH cells with the DSC-P72, as well as a charger. Get a couple of extra sets of high-capacity NiMH AA cells, and always keep one set charged and ready to go while the other is in the camera.

Specifications

• Color: The P72's color is very good overall, with good levels of saturation, and generally accurate hue.  Both the Auto and Incandescent settings produced very warm images in the Indoor Portrait without flash. Outdoors, color was very good.
  
  
• Exposure: The P72 did pretty well exposure-wise, and generally produces good-looking pictures. In harsh lighting, its dynamic range is a bit limited, with a tendency to lose highlight detail and plug shadows slightly. The indoor portraits required about average positive exposure compensation, and exposure looked about right. All in all, exposure performance was on the good side of average.
  
  
• Closeups: The DSC-P72 performed about average in the macro category, capturing a minimum area of 3.73 x 2.80 inches (95 x 71 millimeters). Resolution is high. Details are just a hint soft, but still well-defined. Corner softness is also present, but not terribly strong. The DSC-P72's flash had trouble throttling down for the macro area, and overexposed the shot. Plan on using an external light source when snapping macro shots with the P72.
  
  
• Night Shots: Like many of Sony's digicams, the DSC-P72's Twilight shooting mode doesn't access the camera's ISO adjustment. With a maximum shutter time of two seconds, however, the camera's low-light capabilities were a little limited. In Twilight mode, images were bright only as low as one foot-candle (11 lux), which is about equivalent to average city street lighting at night. Even at that level though, the overall image was just a hint dim. Images shot at ISO 100 and 200 produced similar results, though the ISO 200 image was brighter. At ISO 400, images were bright as low as 1/2 foot-candle (5.5 lux), so the camera should do quite well for typical outdoor night shooting in reasonably well-lit areas. Color looked pretty good, though with the slightest red cast in the dimmer shots. Noise was low at ISO 100, but increased to a moderately high level at ISO 400. Low light shooting is also aided by a bright (optional) autofocus-assist light, providing good focusing capability even in very dark surroundings.
  
  
• Viewfinder Accuracy: The DSC-P72's optical viewfinder is a little tight, showing approximately 80 percent frame accuracy at wide angle, and approximately 84 percent at telephoto. (Most digicams have optical viewfinders falling into this accuracy range) Images framed with the optical viewfinder are shifted slightly toward the lower left corner of the frame as well. The LCD monitor is much more accurate, showing approximately 99 percent of the frame at wide angle, and 99+ (99.8) percent at telephoto. The DSC-P72's LCD monitor is essentially perfect in this regard.
  
  
• Optical Distortion: Optical distortion on the DSC-P72 is a bit higher than average at the wide-angle end. The telephoto end fared better, a 0.4 percent barrel distortion there. Some corner softness was present in wide angle shots, but the effect wasn't too strong overall. Overall, an "average" lens performance.
  
  
• Battery Life: Battery life on the P72 is pretty decent for a camera powered by only two AA cells. Worst case run time with "standard" 1600 mAh batteries would be about 100 minutes, rising to 220 minutes in capture mode with the LCD off. The P72 ships with a pair of 1850 mAh Sony-branded batteries. Despite the reasonably good run time performance of the P72, pick up another set or two of high-capacity NiMH rechargeable batteries.
