Sensor and Image Quality Showdown

Image quality is the heart of your purchase decision. Both cameras utilize Four Thirds sensors, but technology improvements over the three-year gap between releases show in details:

The E-PL3 edges out in resolution and ISO flexibility, but both produce solid image quality.

While sensor size and chip area stay consistent, the E-PL3’s TruePic VI processor delivers improved noise handling and better high ISO performance up to ISO 12800 versus the E-420’s ISO 1600 max. In real-world shooting, that translates to cleaner low-light images on the E-PL3, crucial for night, event, and street photography.

Dynamic range results are similar, so both can capture details in shadows and highlights quite well, but the E-420’s slightly better color depth indicates richer tonality in controlled lighting like portraits and landscapes.

From our real-world tests, the E-PL3’s 12MP files offer a nice balance of resolution versus noise. The E-420 holds strong in daylight conditions, especially at base ISO 100, producing vibrant colors with slightly less noise.

Displays and Viewfinders: Seeing Your Composition and Settings

User interface quality directly affects your shooting experience:

E-PL3’s larger, higher resolution, tiltable screen offers a clear advantage in composing shots from challenging angles.

The E-PL3’s tilt-and-swivel LCD is invaluable for low or high angle shooting, macro work, and self-portraits. Its HyperCrystal LCD also improves visibility under sunny conditions. Meanwhile, the E-420 employs a traditional optical viewfinder offering a real-time, lag-free view - great for action photography and conserving battery life.

If you appreciate the immediacy of an optical viewfinder, the E-420 gives you that classic charm. But for flexible framing and live preview benefits, especially with manual focus or video work, the E-PL3’s screen is a winner.

Autofocus and Shooting Speed: Capturing the Moment

How quickly and accurately your camera locks focus can make or break a shot - especially in fast-paced photography like wildlife or sports.

• E-420 Autofocus: Employs a hybrid AF system with 3 focus points using both phase and contrast detection. It provides single, continuous, and selective AF modes but lacks advanced tracking technologies.
• E-PL3 Autofocus: Relies solely on contrast detection with 35 focus points and introduced face detection AF, including continuous AF tracking - an evolution in user-friendly focusing.

The E-PL3’s 6fps burst rate and advanced AF systems give it a clear edge for capturing fleeting expressions in portraits, decisive wildlife moments, and quick street scenes. The E-420’s 4fps and limited AF coverage may frustrate sports photographers who demand reliable tracking.

Flash and Exposure: Flexibility in Challenging Light

• Olympus E-420: Comes with a built-in flash offering Auto, Auto FP, Manual, and Red-Eye modes with an effective range of about 12 meters at ISO 100. However, it does not support flash bracketing.
• Olympus E-PL3: Lacks a built-in flash but supports sophisticated external flashes with multiple modes and bracketing (AE and WB), granting serious creative control.

In terms of exposure precision, the E-PL3 shines with multi-segment, center-weighted, and spot metering, while the E-420 provides more basic metering. The E-PL3 also offers higher maximum sync speeds (160fps vs 180fps in E-420, close in practical terms).

For studio or event photographers planning flash setups, the E-PL3’s flexible system is preferable, while casual shooters may appreciate the convenience of the E-420’s integrated flash.
