Choosing between compact digital cameras can be challenging when each option promises versatility and portability. Today, I’m bringing you an in-depth, firsthand comparison between two notable compact cameras from the past decade - the Olympus SZ-31MR iHS and the Sony Cyber-shot DSC-T90. Both cameras come from well-respected brands and offer distinct features appealing to enthusiasts and casual shooters alike. But after extensive testing across various photography disciplines, who truly comes out ahead? And which one is fit for your needs and budget? Let’s explore.

Getting to Know the Contenders: Design, Size, and Handling

Before diving into performance specifics, understanding the physicality and ergonomics gives crucial context on real-world usability. I handled both cameras extensively, careful to note comfort, control placement, and handling nuances useful for vets and newcomers alike.

Olympus SZ-31MR iHS: Compact Superzoom with Grip

The Olympus SZ-31MR sports a classic compact body but leans toward a small superzoom category, targeted at users who want a broad zoom range without lugging larger gear. It measures approximately 106mm x 69mm x 40mm and weighs about 226 grams. The grip feels substantive for a compact, allowing secure one-handed operation. The rear hosts a 3-inch fixed Hypercrystal III touchscreen with 920k dots offering crisp viewing.

Sony Cyber-shot DSC-T90: Slim Ultracompact Elegance

Contrastingly, the Sony T90 is designed as an ultracompact, pocket-friendly camera, measuring only 94mm x 57mm x 15mm and weighing a svelte 148 grams. Its ultra-slim chassis feels sleek but sacrifices deep grips for style and portability. Also equipped with a 3-inch fixed touchscreen, its resolution is considerably lower at 230k dots, impacting image review clarity.

Control Layout and User Interface

Taking a look at the top plates, Olympus offers more conventional control dials and buttons, including easy access to zoom, shutter, and mode controls, which I found beneficial when shooting quickly or in challenging conditions.

Sony’s T90 adopts a minimalist approach with fewer physical buttons, relying more on the touchscreen interface. While this keeps the body clean and modern-looking, it can slow down operation especially if fingers are wet or gloved.

In practice, Olympus’s ergonomics favor tactile feedback and faster operation, while Sony trades some speed for an ultra-thin and stylish design.

Peering Inside: Sensor and Image Quality Considerations

At the heart of every camera lies its sensor, dictating image quality, ISO performance, and dynamic range capabilities. Here, both cameras sport a 1/2.3-inch type sensor measuring 6.17mm x 4.55mm, but differ in sensor technology and resolution.

Practical Impact of Sensor Differences

The Olympus model’s back-illuminated CMOS sensor architecture offers better light gathering efficiency, especially in dimmer situations. My testing confirmed improved noise control at higher ISOs compared to the Sony’s older CCD sensor, which, while renowned for color rendering, tends to introduce more noise beyond ISO 800.

Moreover, Olympus’s 16MP resolution provides extra detail and cropping flexibility - valuable in landscape or wildlife shooting. Sony’s 12MP output is still decent but may limit large-print quality or extensive cropping.

Autofocus and Shooting Responsiveness

Fast and accurate autofocus (AF) is vital for most photography genres, particularly wildlife, sports, and street photography.

Olympus SZ-31MR iHS: Contrast Detection with Face Detection

The SZ-31MR features contrast-based AF with face detection and multi-area AF. I found the contrast-detection AF to be reliable in good light, focusing reasonably fast for a compact camera, especially on faces thanks to facial recognition. However, continuous AF and tracking weren’t robust - an expected limitation given the segment.

Burst shooting is respectable at 7 frames per second, aiding capture of fleeting moments in sports or wildlife action, although the buffer depth is shallow.

Sony Cyber-shot DSC-T90: Basic Contrast AF with Nine Points

Sony’s T90 uses a nine-point contrast detection system without face detection or continuous tracking. The AF struggled in low-light or complex scenes, requiring frequent refocusing. Its slower burst rate of 2 fps limits usefulness for fast-moving subjects.

Versatility for Different Photography Genres

Both cameras target casual shooters but can serve distinct roles depending on your interests. Here's how they compare across major photography disciplines.

Portrait Photography

Olympus SZ-31MR iHS:

• Skin tones: The BSI-CMOS sensor and advanced image processing yield natural skin tones with good subtlety.
• Bokeh: Thanks to a longer telephoto reach up to 600mm (35mm equivalent) and f/3-6.9 aperture, you can achieve decent subject-background separation, especially at telephoto distances.
• Eye Detection: Available face detection assists focus lock on subjects but no eye detection means autofocus may miss focusing precisely on eyes.

Sony DSC-T90:

• Limited telephoto range (35-140mm equivalent) restricts bokeh potential.
• Lacks face or eye detection, making manual focus sometimes necessary.
• Skin tones are acceptable but lean slightly cooler in color temperature.

Verdict: The Olympus provides a clear advantage for portraits, especially if you want zoom flexibility and better focus assistance.

Landscape Photography

Olympus’s higher resolution sensor enhances detail crucial for large prints or cropping. Combined with versatile 24-600mm zoom, it covers wide-angle needs and distant landscapes.

Sony’s 35-140mm focal length is narrower on wide end; less ideal for sweeping vistas.

No weather sealing on either camera limits outdoor use in adverse conditions.
