Olympus Stylus 5010 vs Sony Cyber-shot DSC-T99: An Ultracompact Camera Showdown

When it comes to ultracompact cameras, few things matter more than size, image quality, and ease of use, all wrapped in a sleek design that appeals to casual shooters and enthusiasts alike. Both the Olympus Stylus 5010 and the Sony Cyber-shot DSC-T99 emerged in 2010 as contenders for pocket-sized everyday cameras. What separates these two cameras, and which one deserves a spot in your photo bag?

Having personally tested hundreds of cameras across all categories, including numerous ultracompacts, I dove deep into comparing Olympus 5010 and Sony T99 along multiple crucial frontiers: sensor and image quality, autofocus and performance, handling ergonomics, and practical uses for different photography genres.

Let's pull back the curtain on what each camera brings to the table - and what you might be trading off when choosing one over the other.

First Impressions: Size, Feel, and Controls

Before unpacking specs, the physical experience of holding and operating a camera is a vital element to consider, especially in the ultracompact category where every millimeter and gram counts.

As shown in the image above, both the Olympus 5010 and Sony T99 are exceptionally small, but there are subtle differences. The Olympus 5010 measures 95 x 56 x 20 mm and weighs around 126 grams, while the Sony T99 is slightly smaller and lighter at 93 x 56 x 17 mm and 121 grams.

The T99 emphasises ultra-thin proportions and a smooth, streamlined body design, featuring a capacitive touchscreen - rare for 2010 - whereas the 5010 sticks to traditional physical buttons and a fixed type LCD without a touchscreen.

Looking at their control layouts (above), the Olympus 5010 adopts a minimalist approach: shutter release and zoom levers dominate the top, with limited external buttons. Its compact nature limits direct access to advanced controls, reflecting Olympus's design choices to keep it simple.

By contrast, the Sony T99 offers slightly more versatility with a touch interface, albeit still basic by modern standards. Unlike the 5010, the T99 includes a few more dedicated buttons for white balance and flash modes, reflecting Sony’s focus on quick in-camera settings tweaks.

Ergonomically, both feel somewhat delicate compared to larger enthusiast compacts, but for their class, the Olympus 5010 affords a slightly better grip thanks to a thicker body.

Sensor and Image Quality: The Heart of the Camera

At the core of any camera’s ability to produce pleasing images lies the sensor and image processing pipelines. Both these cameras feature 1/2.3-inch CCD sensors with 14-megapixel resolution, but subtle implementation differences impact image quality.

The Olympus 5010's sensor size is roughly 6.08 mm x 4.56 mm, yielding an image area around 27.7 mm², while Sony’s sensor measures 6.17 mm x 4.55 mm (about 28.1 mm²) - a marginally larger active area.

On paper, the Sony T99 offers a slightly better maximum aperture range of F3.5–4.6, compared to Olympus’s slower F2.8–6.5 range. At wide angle, Olympus has an edge with a brighter F2.8 lens, aiding in low-light and depth-of-field control, but Olympus falls off more steeply toward telephoto.

Through hands-on testing, I found the Olympus 5010 delivers slightly better low-light performance and marginally cleaner images at maximum ISO 3200 because of its lens advantage in aperture at the wide end. In good light, both cameras produce equivalent fine detail, though both struggled with noise beyond ISO 800.

Color reproduction leaned a bit toward cooler tones on Sony’s CCD output, while Olympus images have a warmth that benefits portrait skin tones.

Neither camera supports RAW capture, limiting post-processing flexibility - a notable restriction for enthusiasts seeking maximum creative control. Both shoot JPEG exclusively, optimized via their proprietary image processors: Olympus’s TruePic III versus Sony’s Bionz.

Autofocus and Performance: Speed vs Precision

Contrast-detection autofocus dominates in ultracompacts of this era, and both Olympus and Sony rely on this approach. The T99 offers a faster continuous burst rate of 10 fps, compared to the 5010's 1 fps, but Olympus’s single-shot focus lock felt more consistently accurate in my hands during tests.

Olympus enables autofocus tracking, albeit crudely due to few focus points and no face detection - a feature missing from both cameras. Sony supports 9 focus points with center-weighted emphasis but lacks reliable tracking for moving subjects.

Starting shutter speeds are better on the Olympus side, reaching down to 4 seconds for long exposures compared to Sony’s 2 seconds minimum, useful for night shoots or creative light painting. However, Olympus’s maximum shutter speed is faster at 1/2000 s vs Sony’s 1/1250 s, helping freeze motion quicker.

LCD Screens and User Interface

Viewing and composing images is heavily dependent on screen quality and interface responsiveness.

Sony’s 3-inch touchscreen on the T99 boasts a 230k-dot resolution, offering a slightly larger, more modern interface than Olympus’s 2.7-inch fixed, non-touch screen at the same resolution.

While the touchscreen may appear attractive, responsiveness is modest by today’s standards and sometimes lagged when navigating menus or adjusting exposure settings.

Olympus's more traditional button-centric user interface is straightforward but limited, favoring simplicity over control depth.

Lens Versatility and Macro Performance

Both cameras have fixed lenses with respective zoom ranges:

• Olympus 5010: 26–130 mm (5x zoom), aperture F2.8–6.5
• Sony T99: 25–100 mm (4x zoom), aperture F3.5–4.6

Olympus offers a slightly longer telephoto reach, which benefits casual zoomed-in compositions - landscapes, distant subjects, or portraits requiring tight framing.

Sony has an edge in macro capability, supporting focus as close as 1 cm, compared to Olympus's 7 cm. This close focusing distance enables the T99 to capture fine details of flowers, insects, and textiles without additional accessories.

For image stabilization, Olympus uses sensor-shift stabilization, while Sony employs optical image stabilization (OIS). Both work well enough to reduce shake-induced blur at moderate telephoto and low shutter speeds, but I found Olympus's sensor-shift a bit more effective when shooting handheld in dim conditions.

Video Capabilities: Modest But Useable

Neither camera breaks new ground regarding movie features in 2010 standards, offering basic capabilities:

• Both shoot 1280 x 720 (HD) video at 30 fps.
• Olympus uses Motion JPEG, Sony employs MPEG-4 codec.
• Neither camera has microphone or headphone ports.
• Neither supports 4K or advanced video modes.

Sony’s video suffers from early generation compression artifacts but benefits from faster autofocus during recording. Olympus video is softer overall but has better image stabilization in motion.

Connectivity and Storage

In a nod to early wireless aspirations, the Sony T99 comes Eye-Fi compatible, allowing selective wireless transfer via compatible SD cards. Olympus lacks any wireless features, sticking to USB 2.0 and HDMI output.

Storage options differ in versatility: Sony supports SD, SDHC, SDXC cards and Sony’s proprietary Memory Stick Duo/Pro Duo, while Olympus accepts only SC/SDHC cards and internal memory.

Battery Life and Practical Use

Each camera uses proprietary lithium-ion batteries: Olympus uses Li-50B, Sony uses NP-BN1. Official manufacturer estimates are unavailable, but real-world use indicates:

• Olympus: sufficient for roughly 250 shots per charge.
• Sony: slightly better endurance closer to 300 shots.

Neither supports USB charging. Given their tiny sizes, carrying spare batteries is advisable on longer outings.

Durability and Environmental Resistance

Both models lack environmental sealing - no weatherproofing, dustproofing, shockproofing, or freezeproofing. This is typical for ultracompacts of the period aimed at casual users rather than rugged professionals.

If you plan to shoot landscapes or wildlife outdoors, take care to protect these cameras from moisture and harsh conditions.

Real-World Genre Performance: Where Each Shines

With specs laid out, what do these cameras actually deliver across popular photography genres? Let me break down tested performance by use case:

Portrait Photography

Olympus edges ahead for portraits, thanks to its wider aperture lens (F2.8 at wide angle). Skin tones render more naturally warm, and images have gentle background separation at 26 mm with close focusing.

However, neither camera offers face or eye detection autofocus, so critical sharpness relies on careful AF single-point placement. Both cameras produced acceptable bokeh for compact camera standards but cannot match larger sensor cameras.

Landscape Photography

Both produce detailed 14 MP images adequate for online or moderate print use. Olympus’s longer zoom allows tighter landscape compositions, while Sony’s slightly wider field of view aids sweeping vistas.

Noise control at ISO 100-200 is good for both, but dynamic range remains limited - typical of CCD sensors. Olympus’s longer shutter speeds offer more creative control in low light, beneficial for twilight or waterfalls.

Wildlife and Sports Photography

Neither camera truly fits fast-action shooting needs. The Olympus 5010’s single fps burst is insufficient for capturing decisive wildlife or sports moments. Sony's 10 fps burst is fast but limited by slow contrast-detect AF and no tracking, resulting in many out-of-focus frames.

Telephoto reach favors Olympus (130 mm vs 100 mm), but the aperture drop-off restricts light gathering and AF precision at the tele end.

Street Photography

Sony’s smaller profile and touchscreen controls make it the better pick for unobtrusive street shooting. The fast burst rate is handy for candid moments. However, Olympus’s faster wide aperture wins for low-light street scenes later in the evening.

Neither camera includes a viewfinder, relying solely on LCD framing.

Macro Photography

Sony T99 wins at close-ups with a 1 cm macro focusing distance, enabling highly detailed shots straight out of the box, a feature unusual for ultracompacts.

Olympus’s 7 cm minimum focus distance limits creative macro potential, though sensor-shift stabilization helps handholding.

Night and Astro Photography

Both support up to 4-second long exposures, but Olympus’s longer shutter speed ceiling (up to 4 seconds, versus Sony’s 2 seconds) offers marginal leverage for star trails and night scenes.

ISO performance is weak for astrophotography due to CCD noise characteristics at high ISO. Neither camera supports bulb mode or RAW, both critical for serious night shooters.

Video

Both provide 720p video recording at 30 fps, with neither enabling manual exposure control nor external mic inputs.

Sony’s Bionz processor and MPEG-4 codec deliver slightly better compression efficiency. Lack of image stabilization (except optical) and low bitrates limit creativity.

Travel Photography

Both cameras excel in compactness and pocketability, ideal for travel photographers valuing convenience over pro-level features.

Olympus’s slightly better lens reach and stabilization edge it forward for varied shooting. Sony’s touchscreen and faster burst rate appeal for travel snapshots and events.

Battery life is modest for both; packing spares is necessary.

Professional Work

Neither camera suits professional workflows fully, lacking RAW support, robust build, or reliable autofocus features.

However, as secondary or backup cameras, their compactness and simplicity might appeal to pros wanting an easy carry-around in non-critical situations.
