Olympus E 620 Best Features

Megapixel 12.3
12.3 MP Live MOS sensor and the TruePic III+ image processing engine to provide accurate color fidelity, sharp detail, professional picture quality, and overall superior performance. The sensor delivers excellent dynamic range and a state-of-the-art amplifier circuit to reduce noise and capture fine image details in both highlight and shadow areas.

[+] Image Stabilization
IN BODY IMAGE STABILIZATION (3 MODES). The E-620 features In-body Image Stabilization. That means you can use any Four Thirds lens, from wide-angle to telephoto, for perfectly clear, crisp photos no matter what the shooting situation, even in low light situations. With the E-620, you can compensate for camera shake by up to four shutter speed steps.

Dust proof sensor
The Olympus dust reduction system is an industry first and a proven technology. Every time you turn on the E-620, our Supersonic Wave Filter™ — located between the shutter and the image sensor — silently vibrates an amazing 30,000 times per second. Dust will no longer get between you and a great shot.

LIVE VIEW AND AF: ELEVEN POINT IMAGER AUTO FOCUS
In Live View the E-620 uses the advanced Autofocus technology of the E-30 with 11 dedicated AF points for fast and accurate focus.

[+] SHADOW ADJUSTMENT TECHNOLOGY
Shadow Adjustment Technology compensates for extreme contrast when shadowed areas lack visible detail. Shadow Adjustment Technology adjusts the exposure in the shadows while retaining all the detail in the bright areas.



Additional features/specification

Built-in image sensor cleaning
Dust that settles on the sensor surface is removed using ultrasonic vibration. This Self Cleaning Sensor Unit routine is automatically activated whenever the camera is powered on or off. (It can also be manually activated.)

Live View
The EOS Rebel XSi has a huge, bright 3.0-inch TFT LCD monitor with 230,000 pixels and a viewing angle of 170°. Live View Function enables you to view your subjects directly on the huge 3.0-inch LCD monitor. It’s easy to magnify any part of the scene 5x or 10x for precise manual focus.
