Olympus E-30 vs Pentax E90 sensor size comparison

Inside the Camera: Sensor Technology and Image Quality

Sensor size and technology hugely impact image fidelity, dynamic range, and noise performance.

  • Olympus E-30 uses a 12 MP Four Thirds CMOS sensor (17.3 x 13 mm) with TruePic III+ image processor.

    • Larger sensor area (224.9 mm²) allows better light gathering and higher image quality.
    • Native ISO 100-3200 with good low-light capability (DxO Low Light ISO Score ~530).
    • Antialias filter helps reduce moiré, with multiple aspect ratio options including 1:1 and 16:9.
    • Supports RAW files, enabling extensive post-processing flexibility.
  • Pentax Optio E90 uses a smaller 1/2.3” CCD sensor (6.08 x 4.56 mm), 10 MP resolution.

    • Smaller sensor area (27.72 mm²) limits dynamic range and noise performance.
    • ISO up to 3200 but with significantly higher noise above ISO 400.
    • No RAW support; only JPEG images, limiting downstream editing.
    • The lens’s 3x zoom range (32-95 mm equiv.) is standard for casual use but less versatile.

In terms of pure image quality potential, the Olympus E-30’s Four Thirds sensor beats the Pentax compact sensor across sharpness, color rendition, and dynamic range.

Olympus E-30 vs Pentax E90 Screen and Viewfinder comparison

Working with Displays and Viewfinders

A good display and viewfinder are crucial for composition, focusing, and reviewing shots.

  • The Olympus E-30 features a 2.7” fully articulated screen with “HyperCrystal II” LCD technology, providing vibrant colors and solid visibility even in bright outdoor conditions. Articulation expands possibilities for low/high angle shooting, helpful in macro, portraiture, and videography (although the E-30 lacks advanced video recording).

  • Optical pentaprism viewfinder with 98% coverage offers a real-time, lag-free framing experience. While the 0.56x magnification is modest, it still provides an enjoyable DSLR shooting experience.

  • Interface is menu-heavy but functional once you get used to it. NO touchscreen capability means navigating menus require button/dial combos.

  • The Pentax E90 has a fixed 2.7” LCD screen, decent for casual framing and previewing but less visible in bright light and no articulation options.

  • It lacks an electronic or optical viewfinder, which limits compositional precision outdoors or in direct sunlight.

  • Interface is intentionally simplified - great for beginners but frustrating for those wanting manual control.

Autofocus and Speed: Catch the Moment

Autofocus (AF) and shooting speed define a camera’s ability to freeze fleeting moments, crucial for wildlife, sports, and event photography.

Olympus E-30 AF System:

  • 11 focus points with phase-detection on the dedicated AF sensor array.
  • Supports contrast-detection AF in live view.
  • Face detection available, though not as refined by modern standards.
  • AF continuous mode allows tracking moving subjects but without advanced subject recognition or animal eye detection.
  • Burst rate of 5 fps is decent for mid-level DSLR standards from 2009 and viable for sports or action under moderate constraints.

Pentax Optio E90 AF:

  • Limited 3 focus points; single AF mode only, no continuous tracking.
  • Contrast-detection AF optimized for still subjects; focus speed average for compact cameras.
  • No face detection or animal AF.
  • No burst shooting mode beyond standard single shot.

For fast-paced photography, Olympus clearly outperforms Pentax, letting you track and capture movement more effectively.

How Do Their Images Really Look?

We shot side-by-side in portraits, landscapes, and casual street scenes to compare output.

Olympus E-30:

  • Excellent skin tone rendering with its larger sensor and good dynamic range.
  • The sensor’s image stabilization helps deliver sharp images handheld, especially in low light.
  • Background blur (bokeh) is more pronounced with the right fast primes, beneficial in portraits.
  • Fine detail retention and color depth stand out, allowing better prints and cropping flexibility.

Pentax Optio E90:

  • Good color rendition for a compact sensor, but skin tones can appear slightly flat.
  • Noise and softness become apparent beyond ISO 200.
  • Limited background blur due to small sensor and slower lens aperture.
  • Images work well for casual sharing and 4x6 prints but lack flexibility for large format printing.

If high image quality is a priority, the Olympus is a clear winner, especially for longer-term use and advanced editing.
