Sony DSC-P20 Review
By Movable Type Admin
The CyberShot DSC-P20, DSC-P30 and DSC-P50 are Sony's first digital cameras to use either common AA size batteries or the InfoLITHIUM NP-FS11 rechargeable battery pack. This lets you use "off the shelf" batteries to power the camera or you can purchase the optional battery pack and AC charger/power supply. When using the battery pack you always know how much runtime is left as it is displayed on the LCD screen. The best performance from AA type batteries will be realized by using high-power (1500mAH or better) NiMH cells, alkaline batteries should be used only in emergencies. The P20 and P30 cameras have a slightly different color scheme on the outside and on the inside they are similar except for image resolution; the P20 is 1216x912 and the P30 is 1280x960.
This pocket-sized camera is anything but small on features. The 1.3-megapixel CCD yields up to 1216 x 912-pixel images. JPEG standard or high quality, TIFF uncompressed, special e-mail and text modes as well as MPEG-EX movie mode with recording duration limited only by available space on the Memory Stick. New Sony 12-bit DXP A/D conversion insures better tonal range and highlights. It lacks shutter or aperture priority modes but the Program AE system does have: user-adjustable ISO sensitivity (Auto, 100, 200 or 400), exposure compensation (+/-2EV), matrix or spot metering, flash with redeye reduction and output power settings, variable image sharpness (+/-2), picture effects (solarize, b&w, sepia, negative art) and date stamping. Other hardware features include a bright and very readable 1.5-inch color LCD, real image optical viewfinder and a speedy USB port for downloading to the computer.
Last year's (2000) DSC-S30 and DSC-S50 were good cameras but they lacked optical viewfinders and didn't fit in average sized pockets well. The P series address those two problems quite nicely. The user interface to the camera is still via the color LCD as both cameras do lack information LCD panels found on many other cameras. The menu system is clean and easy to navigate but it does mean that the color LCD has to be powered up to change most camera options. Luckily these are basically point and shoot cameras so the average user will probably only use the menu to change the image size, the operational mode of the camera can be selected from the mode dial on top. When you do need to change settings like the ISO speed or metering, they are easy to get to via the popup menu and 4-way selector switch on the back. You might have to shield the LCD with your hand in high-noon type sunshine but otherwise it is very useable outdoors.
The P series features the MPEG-EX movie recording mode which no longer limits you to clip lengths of 5, 10 or 15 seconds as with previous models. There is no microphone for audio recording but you can capture motion video in 160x112 or 320x240 resolution at 8fps with the duration being limited only by available storage space on the Memory Stick. Forty-five minutes of action can be captured when using a 64MB size stick. Another unique capture mode is the Clip Motion mode that lets you turn up to 10 small (160x112 or 80x72) images into an animated GIF file. Still images can be captured at 1216x912, 1216(3:2 ratio), 1024x768 or 640x480 with two different quality levels of JPEG or as uncompressed TIFF images.
Overall the image quality is good to excellent for a camera in this resolution range. Color and saturation was usually very true to the original and the sharpness can be set to your liking but be careful not to over-sharpen or detail will be lost. There is little to no chromatic aberrations (purple fringe) visible. The flash is on the weak side but this is normal for compact cameras using small flash tubes. Don't expect to be lighting up subjects beyond six feet from the camera unless you're in Twilight mode. You will always capture a lot more in your picture than you see through the viewfinder, its coverage is no more than maybe 70% at best. However, any optical viewfinder is better than NO optical viewfinder at all. The color LCD when used as a viewfinder is much more accurate and shows almost 100% of the actual capture angle but of course it really drains the battery if used too often.
The camera proved to be quite "fast" in normal use. When you first turn it on it takes about 4 seconds before you can capture the first picture, most everything else was surprisingly fast for such an economical camera. The average shot to shot time is less than three seconds no matter what size image you capture (with the exception of uncompressed TIFF images.) The shutter lag (time from pressing the shutter button to actual capture) is nonexistent as this is a fixed-focus lens, there is no autofocus delay. Going from Record to Play mode brings up the last image captured on the LCD in less than two seconds and going from Play back to Record is almost instantaneous.
All things considered I think Sony has another winner here, it's priced right at just
$249 and will make an excellent "first" camera for those venturing into digital. If you
want more features (zoom lens, AF illuminator, etc) or need more image resolution then
look at the multitude of other Sony cameras. The P30 with its
3x zoom lens, the P50 with 3x zoom and a 2.1-megapixel imager,
or the S75 with 3x Zeiss lens and a 3-megapixel imager and all
possible exposure options. For pocket-size fun it is going to be difficult to beat the
P20 or P50, they generate beautiful images and are very affordably priced.
