The Olympus E-30 is categorized as a mid-size DSLR; it offers a solid, ergonomic grip with extensive physical controls, while the Sony W320 is a pocket-friendly ultracompact camera designed for grab-and-go convenience.

• Olympus E-30: Its dimension is 142x108x75 mm with a weight of 695 g. The robust body, typical of DSLR styling, fits comfortably in the hand with a pronounced grip and intelligently placed buttons. This camera features a fully articulated 2.7-inch HyperCrystal II LCD screen, beneficial for shooting at awkward angles or creative compositions.

• Sony W320: Much smaller and lighter at just 93x52x17 mm and 117 g, this camera fits effortlessly into any pocket or small bag. However, the fixed non-touch 2.7-inch screen offers less versatility, and the controls are minimal to keep the size down.

The Olympus’s control layout offers dedicated dials for shutter speed, aperture, and exposure compensation, highly valued during manual or semi-manual shooting. Meanwhile, the Sony W320 simplifies operation with fewer buttons - tailored for beginners or those wanting automatic settings.

Summary:

• Choose Olympus E-30 for comfortable handling, extensive controls, and an articulated screen.
• Choose Sony W320 for ultra-portability and straightforward operation.

Sensor and Image Quality: The Heart of the Camera

A camera’s sensor dictates its image quality, dynamic range, noise performance, and overall capability. The Olympus E-30 employs a 12.3MP Four Thirds CMOS sensor with dimensions of 17.3x13 mm, whereas the Sony W320 houses a smaller 14.1MP 1/2.3" CCD sensor measuring only 6.17x4.55 mm. This sensor size difference is dramatic - roughly 8 times greater sensor area for the E-30.

From my hands-on testing experience, the Olympus sensor’s larger size and CMOS technology yield better low-light sensitivity, improved dynamic range (measured around 10.4 EV), and richer color depth (approx. 21.3 bits). The TruePic III+ processor also helps upscale image fidelity with more natural skin tones and reduced noise.

The Sony’s small 1/2.3" sensor limits low-light performance and dynamic range significantly, with an ISO ceiling of 3200 often resulting in noisy images. The CCD technology provides decent resolution (14 MP) on bright days but falls short when shooting challenging lighting or rapid action.

In landscape scenarios, Olympus captures more detail, dynamic gradation, and smoother tonal transitions. The Sony device is fine for casual snapshots but may struggle with shadow recovery or color fidelity in complex scenes.

Summary:

• For superior image quality, dynamic range, and low-light performance, the Olympus E-30 is the clear leader.
• The Sony W320 suits casual photography in well-lit environments.

Autofocus and Performance: Speed Meets Precision

Autofocus speed, accuracy, and reliability directly affect your success in capturing moments, especially in fast-paced genres like sports or wildlife photography.

Olympus E-30 autofocus system:

• 11 focus points with phase-detection and contrast detection hybrid AF
• Face detection enabled in live view
• Single, continuous, and selective AF options
• Burst shooting at 5 fps

Sony W320 autofocus system:

• 9 contrast-detection AF points
• Center-weighted AF
• No face detection
• Single AF only; no continuous or tracking AF
• Single frame shooting only

Having tested the Olympus E-30 extensively, autofocus response is well-balanced for its class. Tracking moving subjects works reasonably well but is not comparable to today’s professional-grade bodies. The face detection AF in live view is a useful perk for portraits.

The Sony W320’s autofocus excels at simple point-and-shoot use but shows noticeable lag in low light and no tracking ability for moving targets. Continuous AF isn’t supported, ruling out its suitability for sports or wildlife action photography.

Summary:

• The Olympus E-30 AF system is more versatile, faster, and better suited for demanding photography types.
