In contrast, the Sony NEX-3 delivers a compact, lightweight rangefinder-style mirrorless body aiming for portability and ease of use among photography enthusiasts transitioning from point-and-shoots or compact fixed-lens cameras.

Olympus E-1: A Rock Solid Pro Workhorse

Weighing in at 735 grams and measuring 141 x 104 x 81 mm, the E-1 is hefty for a Four Thirds sensor camera, but this heft lends itself positively to stability and ruggedness. It boasts environmental sealing - an uncommon feature in its era - offering dust and splash resistance essential for professionals shooting in challenging outdoor or inclement conditions. The pronounced handgrip and tactile button layout ensure confident single-handed operation even with larger zoom or telephoto lenses mounted. However, users with smaller hands report some wrist fatigue during extended handheld shooting sessions, a tolerable trade-off when considering its durability and control.

Sony NEX-3: Compact and Lightweight Convenience

The NEX-3 tips the scales at 297 grams and measures a compact 117 x 62 x 33 mm, delivering genuine pocketability for mirrorless systems of its day. Without the bulk of a DSLR prism housing and mirror mechanism, it favors easy portability for travel and street photographers wishing to stay discreet. While lacking weather sealing, the solid polycarbonate build still feels robust for casual daily use. However, the smaller body restricts the number of direct controls, placing increased reliance on menu navigation and rear-screen adjustments which slightly slows down operation under time-pressured circumstances.

Control Layout and Interface: Navigating Settings Efficiently

The cameras’ contrasting form factors lead to significant differences in how photographers interact with and customize camera settings, impacting shooting speed and ergonomics.

• Olympus E-1 features dedicated dials for shutter speed, exposure compensation, ISO selection, and aperture control (via lens), complemented by physical buttons for drive mode, metering, and white balance. A small monochrome top LCD provides at-a-glance exposure data, while a robust optical viewfinder with 100% coverage aids precise framing and composition.
• The Sony NEX-3, aimed at beginners and hobbyists, has a minimalist top plate lacking external controls except a mode dial and shutter button. Instead, users rely on the rear 3-inch tilting TFT LCD (920k dots) for setting adjustments and framing, augmented by a streamlined menu system. Absence of a viewfinder impacts shooting in bright light conditions but is consistent with its consumer-focused design.

While the E-1's controls foster faster manual operation essential for pros in dynamic environments, the NEX-3's reliance on the bigger LCD screen makes it more accessible for novices and learners.

Sensor Technology and Image Quality: The Heart of Photographic Output

One cannot compare cameras without a deep dive into their sensors - the linchpin determining resolution, low-light capability, dynamic range, and ultimately, image fidelity.

A Generational Leap: CCD Four Thirds vs CMOS APS-C

• Olympus E-1: Utilizes a 5.0-megapixel Four Thirds-format CCD sensor measuring 17.3 x 13 mm, with a crop factor of approximately 2.1x. While modest by today's standards, at release it delivered impressively sharp stills with accurate color reproduction. The sensor includes an optical low-pass (anti-alias) filter to mitigate moiré at the cost of slightly softer detail. It supports ISO 100-3200, albeit with noticeable noise levels creeping upward beyond ISO 400, typical of CCD technology.
• Sony NEX-3: Equipped with a 14-megapixel APS-C CMOS sensor, approximately 23.4 x 15.6 mm with a 1.5x crop factor. This sensor offers a substantially larger imaging area, resulting in improved dynamic range (12 EV measured by DxOMark), superior high ISO performance (ISO 200-12800 native range), and finer detail rendition capable of large prints or extensive cropping. The CMOS architecture enables faster readout and reduced noise, especially beneficial in low light and for video recording.

The NEX-3's sensor clearly outclasses the E-1 in resolution and noise performance, attributable both to sensor size and decade-plus technological progress. However, the E-1 retains its charm for classic color rendition and Four Thirds lens compatibility.

Autofocus Systems: Precision, Speed, and Practical Usability

The autofocus (AF) mechanism is crucial, especially for action, wildlife, or event photography where responsiveness and accuracy can make or break the shot.

The E-1’s phase-detect system offers reliable focusing in typical daylight conditions but with only three focus points, it requires more deliberate recomposition. Continuous AF tracking is rudimentary at best.

Conversely, the NEX-3 relies on contrast-detection with wider coverage (25 zones), boosting accuracy for still subjects and incorporating face detection to aid portraits. Live view AF and faster but less consistent performance in tricky lighting matter for casual shooting and video use.

Viewing and Composing: Optical Versus Electronic Displays

• Olympus E-1: Equipped with an optical pentaprism viewfinder offering a bright, clear 100% frame coverage with 0.48x magnification - critical for precise manual focusing and tracking fast subjects. The 1.8-inch LCD screen (134k dots) is small and low resolution, intended primarily for image review rather than live framing.
• Sony NEX-3: Lacks any viewfinder, instead relying entirely on a tilting 3.0-inch 920k-dot TFT LCD which serves for both framing and menu navigation. This screen’s tilt functionality allows versatile shooting angles - an advantage for street and travel photography - but the absence of an eye-level finder can hamper visibility in bright sunshine.

From an enthusiast or professional perspective, the E-1’s optical viewfinder is a significant advantage for spontaneity and accuracy, whereas the NEX-3’s screen-centric approach prioritizes accessibility and compositional experimentation.
