Description:

You'd be hard-pressed to find a digital camera that captures better images than those from the Olympus E-20N. The camera pairs a 5-megapixel sensor with a high-quality custom-designed 4x zoom lens for photos with clarity that rivals film.

First, a note about naming conventions: this camera is also known as the E-20 and the E-20P. The N in E-20N signifies that this is an NTSC (North American) model. European versions are called E-20P because their video-out feature is designed to work with PAL televisions. The models are otherwise identical.

Design and Optics
The E-20N looks and feels like a high-quality professional film SLR. It's hefty, weighing in at 37 ounces, due both to the glass in the lens and the camera's cast-aluminum body. Unlike other digital cameras in its class, the lens on the E-20N is not removable, which is both a good thing and a bad thing. Digital SLRs from other manufacturers typically include just the camera body, and adding a quality lens is a substantial additional expense. Olympus asserts that having removable lenses exposes the sensor to dust, but digital SLRs from Nikon, Canon, and Fuji all use removable lenses, and dust isn't a widely reported problem with those models. Olympus also states that using a lens specifically designed for a digital camera produces sharper images than using a lens designed for a 35mm SLR. This makes sense, since the imaging sensor in a digital camera is smaller than a 35mm negative.

The lens on the E-20N contains aspheric elements, ED elements, and a Gauss-type lens group--features designed to maximize image quality, and typically found only on high-end lenses. In 35mm terms, the lens zooms from 35-140mm, with a maximum aperture of f2.0 to f2.4, depending on how much zoom is used. If you're looking for even more flexibility, add-on lenses ranging from 28mm to 420mm are available.

To compose your photos, either use the swivel-mounted 1.8-inch LCD on the back of the camera or look through the traditional-style ground-glass viewfinder. Most digital SLRs use a mirror to send light to either the viewfinder or the CCD sensor, but the Olympus uses a beam-splitter--basically a prism--to illuminate the viewfinder and the sensor simultaneously. The LCD monitor also sits on a hinge, letting you tilt it up 90 degrees, or down 20 degrees, so you can take pictures from unusual camera angles while still accurately framing the scene.

The 5-megapixel CCD sensor on the E-20N is one of the highest-resolution sensors currently available and captures images with filmlike detail. Like most CCDs, this unit retains a design limitation handed down from the device's origins in television cameras: it is an interlaced chip, which means the camera reads information from the CCD twice--once for all pixels in the sensor's even rows, and again for all the odd rows. The camera then merges these two sets of data into a single image. This technology limits the top shutter speed in 5-megapixel mode to 1/640th of a second--reasonably quick, but not fast enough for high-speed photography. To get around this limitation, Olympus has added a progressive-scan feature to the camera. In simple terms, this mode only reads information from half of the pixels on the sensor (and limits your photos to 2.5 megapixels), but increases your shutter speed to a screaming 1/18,000th of a second, increasing the camera's flexibility tremendously.

More Features
Shooting options on the E-20N include all of the typical modes you'd expect to see on a high-end consumer digital camera: program, aperture priority, shutter priority, and manual shooting modes. Other user-controlled settings include exposure compensation, metering mode, ISO setting, flash, white balance, and focus. Users can leave white balance on auto, select from a number of kelvin temperatures, or manually create a preset. The built-in flash features red-eye reduction, auto, fill-in, and off modes. External flashes can connect to the E-20N through the hot-shoe on top of the camera. Exposure compensation can be set from -3 to +3 EV in one-third EV increments. The ISO can be set to 80, 160, or 320. Also, an autobracketing feature takes three pictures, one over exposed and one under exposed, and allows you to set the exposure compensation up to one EV step in either direction, in one-third EV step increments. A histogram function lets you view exposure information after you capture an image, giving you instant feedback about how to improve your picture-taking skills. A large internal buffer allows the E-20N to take up to take up to four shots in sequence at three frames per second, even when set to record images as uncompressed TIFFs.

Power
The E-20N uses four AA or two CR-V3 lithium batteries--a set of the lithium batteries is included. These batteries have a long life, but they aren't rechargeable, so they're not a good long-term solution unless you're an extremely occasional photographer. We strongly recommend using a set of rechargeable nickel-metal hydride (NiMH) batteries.

Storage and Transfer
Unlike most other digital cameras, the E-20N uses both SmartMedia and CompactFlash (Type I and II, including the IBM Microdrive) for storage, and can use both simultaneously. The camera has slots for both types of cards, and a menu setting lets you toggle between the slots for storage. The included 32 MB SmartMedia card holds 11 pictures at full resolution with normal compression or two pictures in uncompressed TIFF mode. The card can be erased and reused over and over, but if you plan to take more than 11 photos on an outing, then you'll want a higher-capacity card--a 256 MB CompactFlash card, for example, holds around 80 photos at default settings.

Contents and Recommended Accessories
The kit includes the camera, lens hood, lens cap, video, and USB cables, strap, lithium disposable batteries, wireless remote control, 32 MB SmartMedia card, basic manual, and software on CD, including Adobe PhotoShop Elements. Everything you need to get started is included in the box, but to make the most of your camera, we strongly recommend a higher-capacity memory card, rechargeable batteries, and a carrying case. Compatible accessories for this camera are listed near the top of this page.

Conclusion
For serious 35mm SLR users considering a digital camera, the E-20N is a natural choice. The camera feels extremely solid, and controls are logically arranged. Thanks to the high-resolution sensor and fine lens, picture quality is excellent. Admittedly, there are still some areas where the E-20N can't keep up with a film camera, but unless you're a sports or news photographer who needs to blast through a roll of film in five seconds, or someone who requires an unusual lens, this Olympus should offer the features and performance you need. --Shane Burnett

Pros:

  • 5-megapixel sensor captures filmlike detail
  • Features, appearance, and performance are all similar to a 35mm SLR
  • Dual memory card slots let you choose your format--or load both slots for more capacity

Cons:

  • Though the lens is of extremely high quality, competitors' models feature detachable lenses
  • Rechargeable batteries and more memory are necessities for long-term use
