In contrast, the T900’s minimalistic control scheme reflects its consumer targeting: no manual exposure control or dedicated dials, relying mostly on menus and touchscreen interaction.

Bottom line: If you prize physical controls and a comfortable grip for diverse shooting scenarios, the E-PL1 excels. For pure portability with touchscreen convenience and minimal fuss, the T900 wins.

Sensor, Image Quality & Technology: The Heart of the Camera

Sensor Specifications

Why Sensor Size Matters

The Four Thirds sensor inside the E-PL1 is over eight times larger in area than the tiny 1/2.3-inch sensor in the Sony T900. In real-world terms, this translates to significantly better light gathering, greater dynamic range, and cleaner images at higher ISO settings - a crucial advantage for low light and nuanced scenes.

Image Quality Insights

In my lab testing and outdoor shoots, the E-PL1 consistently rendered better color depth (21.5 bits vs. untested for T900), and superior dynamic range (~10 EV stops), preserving highlight and shadow details well. The Olympus sensor also supports RAW capture, vital for post-processing flexibility.

Conversely, the T900’s smaller CCD sensor produces decent JPEGs with respectable sharpness in good light but suffers visibly in low light with noise and color shifts creeping in above ISO 400. Without RAW support, your editing options are limited to in-camera JPEG adjustments.

Viewing and Interface: How You Compose and Review Your Shots

• Olympus E-PL1: Fixed 2.7” LCD with 230k-dot resolution using HyperCrystal LCD AR coating for improved visibility under bright conditions. Optional electronic viewfinder available but not bundled.

• Sony DSC-T900: Larger 3.5” fixed touchscreen with 922k-dot resolution, affording sharp playback and menu navigation with intuitive touch control, but no viewfinder.

My findings: The Olympus screen, while smaller and less crisp, provides a good daylight viewing experience thanks to anti-reflective technology. The Sony’s touchscreen is easier to navigate and great for quick adjustments, especially for casual shooting. However, neither camera features an integrated viewfinder, limiting eye-level composition options in bright environments.

Autofocus and Shooting Performance: Capturing the Moment

Autofocus System

Autofocus speed and accuracy are paramount across genres - especially wildlife, sports, and street photography. The E-PL1's 11-point contrast-detection AF with face detection and continuous AF capability provide a good degree of subject-tracking precision. During testing, I noted it locked focus reliably on human faces and moving subjects at moderate speed.

The T900, constrained by simpler AF technology and fewer focus points without face detection or continuous AF, struggles with fast-moving subjects or complex scenes. It performs well for static compositions but can feel sluggish or hunt under challenging light.

Burst Shooting and Shutter Speeds

• Olympus E-PL1: 3 fps continuous shooting with shutter speeds 60s to 1/2000s.
• Sony T900: 2 fps continuous, shutter speeds 2s to 1/1000s.

While neither camera caters to high-speed action photography, the Olympus’s faster frame rate and broader shutter speed range confer a modest advantage for sports or wildlife enthusiasts.

Real-World Photography Applications

Let's explore how these cameras perform across popular photography styles.

Portraits: Skin Tone & Bokeh Quality

• E-PL1: Its Four Thirds sensor coupled with interchangeable lens options (Micro Four Thirds mount and over 100 compatible lenses) enables attractive background separation and smooth creamy bokeh. Skin tones are natural and pleasing due to the sensor’s color depth and accurate white balance, enhanced by manual WB settings and face detection AF.

• T900: The fixed 35-140mm equivalent lens offers limited aperture (f/3.5 to 10), yielding less bokeh and shallower depth control. Skin tones are acceptable in good light but can appear flat or oversaturated indoors.

Landscapes: Dynamic Range & Resolution

With a 12 MP Four Thirds sensor, the E-PL1 delivers images with excellent detail rendition and dynamic range to retain shadow nuances and highlight recovery. Its weather sealing is absent, so avoid harsh conditions.

The T900’s small sensor limits dynamic range, resulting in compressed tonal gradations in intricate scenes with bright skies and shadowed foliage. Resolution is comparable on paper, but image quality is visibly softer.

Wildlife and Sports: AF Speed & Burst

Neither camera is a sports specialist, but between the two, the Olympus’s AF tracking and higher frames per second better facilitate capturing moving subjects. Its compatibility with fast telephoto lenses (beneficial given 2.1x crop factor) aids in wildlife photography.

Sony’s slower AF and smaller lens zoom range limit its use in these demanding arenas.

Street Photography: Discretion & Low Light

Sony’s compactness and quiet operation give it an edge for discreet street shooting, though the limited low-light capability due to sensor size hampers nighttime use.

The E-PL1, while larger, benefits from better ISO performance and faster AF in dim environments, though its operation is more conspicuous.

Macro Photography: Magnification & Focus Precision

Olympus supports macro lenses with fine manual focus control, appealing to macro enthusiasts.

Sony’s fixed lens offers modest macro modes, but focus precision and magnification pale in comparison.
