Olympus 5010 vs Sony NEX-5T: An Expert Photographer’s In-Depth Comparison

In the ever-evolving world of digital cameras, choosing the right model can be a daunting task, even for seasoned enthusiasts. Today I’m diving deep into two very different cameras launched a few years apart but still holding relevance for certain users: the Olympus Stylus 5010 (aka mju 5010) ultracompact and the Sony Alpha NEX-5T entry-level mirrorless. These cameras cater to substantially different segments, yet a thoughtful comparison is valuable for understanding trade-offs among sensor size, lens options, ergonomics, and overall usability - not just specs stacked in a table.

Having tested both units extensively in various real-world conditions, I’ll walk you through sensor technology and image quality, autofocus systems, handling, and how they perform across diverse photography types. By the end, you’ll have a clear picture of which camera suits your style and budget.

First Impressions: Size, Build, and Ergonomics

When I first handled the Olympus 5010 and the Sony NEX-5T side-by-side, their size difference was immediately striking. The 5010 is what I’d call the quintessential pocket-friendly ultracompact - slim and light enough to disappear into a jacket or purse, whereas the NEX-5T, while still compact, demands a small camera bag or a dedicated space on your shoulder strap.

The Olympus measures a diminutive 95 x 56 x 20 mm and weighs just 126 grams, making it an excellent everyday carry if you want a simple point-and-shoot that won’t remind you it’s there. Conversely, the Sony NEX-5T is bulkier at 111 x 59 x 39 mm and 276 grams, reflecting its interchangeable lens system and more complex internal mechanics.

Looking at the design layouts (see below), Olympus sticks to minimalism - a fixed lens, no manual focus ring, and just a handful of buttons aimed at casual shooting. The Sony, with its larger handgrip and more buttons, clearly targets users wanting greater control and flexibility, including manual exposure modes and autofocus customizations.

Ergonomics-wise, if you often shoot handheld or on the go, the NEX-5T’s size could be a mixed bag: better grip and control but less discreet and convenient than an ultracompact. My personal preference leans toward the Sony when deliberate shooting and handling matter; the Olympus wins points for light travel and spontaneous snaps.

Sensor and Image Quality: Small Chip vs APS-C Excellence

At the heart of these cameras is what defines their photographic potential - the sensor. Olympus employs a 1/2.3" CCD sensor with a resolution of 14MP, while the Sony packs a substantially larger APS-C CMOS sensor (23.4 x 15.6 mm) with 16MP resolution.

Sensor size dramatically influences noise performance, dynamic range, and depth of field control. Olympus’s smaller sensor limits its low-light capability and dynamic range, results you’ll notice once ISO creeps above 400 or shadows demand recovery. I tested both at ISO 800 and above indoors; the 5010’s images exhibited noise and loss of detail quicker than the Sony.

Sony’s APS-C sensor, amplified by the CMOS technology and Bionz processor, enables superior dynamic range and cleaner high-ISO performance, confidently extending up to ISO 3200 and beyond for usable shots. The Sony also supports RAW files, offering extensive post-processing latitude, whereas the Olympus is locked to JPEG only - a significant limitation for enthusiasts who like fine-tuning their captures.

Color reproduction differs as well: Olympus tends toward warmer tones, which can flatter skin but may oversaturate some colors; Sony’s rendition is crisper and more neutral, closer to what I’d call a reference standard.

Autofocus: Tracking and Speed Under the Hood

Autofocus systems can make or break your shooting experience, especially in fast-paced situations like wildlife or sports. The Olympus 5010 offers contrast-detection autofocus only, with limited area selection. It lacks face detection and continuous AF modes, relying mostly on center-weighted focusing.

Sony’s NEX-5T, however, boasts a hybrid AF system combining phase-detection and contrast-detection points, featuring 99 AF points including 25 cross-type sensors, face detection, and continuous tracking for moving subjects.

This translates to noticeably faster and more reliable focusing from the Sony. In my tests shooting street scenes and some wildlife at a local park, the 5010 struggled to lock focus quickly, especially in dimmer conditions or with moving targets. The NEX-5T followed a running dog smoothly, maintaining sharpness despite erratic movement.

Handling Different Genres of Photography: Strengths and Weaknesses

Portrait Photography

When it comes to portraits, skin tone accuracy and bokeh quality matter a lot. Olympus’s fixed 26-130 mm (35mm equivalent) zoom lens with a maximum aperture of f/2.8 at wide end is respectable for casual portraits, but the small sensor restricts background blur and subject separation.

Sony’s advantage here is enormous, with a vast lens ecosystem thanks to the Sony E-mount, allowing use of fast primes like the 50mm f/1.8 with beautiful smooth bokeh and precise eye detection autofocus for tack-sharp eyes.

Landscape and Travel Photography

Landscape shooters benefit from high resolution and dynamic range. Sony’s 16MP APS-C sensor delivers more detailed, vibrant files suitable for large prints, while Olympus’s 14MP sensor and smaller lens translate to softer overall detail and reduced shadow recovery.

For travel, the Olympus’s pocket-size and built-in image stabilization make it an ideal grab-and-go option, though the Sony’s image quality will be more satisfying when you have room to carry it.

Wildlife and Sports Photography

Burst speed and autofocus tracking define performance here. Olympus’s 1 fps continuous shooting falls short compared to Sony’s 10 fps cap, essential for capturing fast action. Lenses are another factor - Sony’s adaptability to long telephoto lenses offers an edge in framing distant wildlife crisply.

Street and Macro Photography

The Olympus’s compactness and stealth make it a subtle street shooter’s tool; you can carry it anywhere, capturing candid moments comfortably. However, the Sony’s tilting touchscreen and faster AF allow more creative framing and assured focus on small details, favorable in macro or close-up work.

Night and Astro Photography

Low-light noise and exposure flexibility count heavily. Olympus maxes out ISO 3200 but with significant noise; Sony’s superior sensor and RAW support let you push ISO higher and apply sophisticated noise reduction confidently.

Video Capabilities: Basic vs Advanced

Olympus provides only 720p HD video recording at 30fps in Motion JPEG format - adequate for casual use but nowhere near professional standards. No microphone input limits sound control, and the lack of 1080p or 4K options is a drawback if you want quality movies.

Sony shines with Full HD 1080p recording at 60 fps, AVCHD and MPEG-4 codecs, and handy built-in WiFi for quick sharing. Its touchscreen aids in focus control during video, though no external mic port limits audio improvements.

Practical User Interface and Screen Evaluation

The Olympus uses a fixed, modest 2.7” LCD with 230k dots - a simple display with limited viewing angles and brightness. Sony’s 3” tilting touchscreen with 922k dots is practically a joy to use, especially for framing tricky angles or reviewing shots on the fly.

The NEX-5T’s touch controls add to an intuitive experience with exposure, focus point selection, and shooting modes accessible through taps, whereas Olympus relies on traditional button cycling with no touchscreen or customizable presets.

Battery Life and Storage

Sony’s battery life rated at approximately 330 shots per charge is quite generous for mirrorless cameras of this class; Olympus specs are less clearly defined but expectedly shorter given the ultracompact form.

Both offer SD card storage, with Sony supporting SDHC/SDXC and Memory Stick formats, whereas Olympus sticks to SDHC only. This flexibility can matter when looking at large capacity cards for extended shooting sessions.

Connectivity and Extras

Olympus 5010 lacks wireless connectivity, making image transfer dependent on cables and card readers. Sony NEX-5T embeds WiFi and NFC, allowing effortless sharing to smartphones or wireless remote control - a big plus in today’s connected world.

Neither offers GPS or environmental sealing, which is consistent with their categories.

Price and Value Assessment

At approximately $150, the Olympus 5010 presents an affordable ultracompact for casual shooters and travelers who prize small size over image quality. The $400 Sony NEX-5T, meanwhile, offers a serious step into interchangeable-lens mirrorless territory with capabilities appealing to enthusiasts and hobbyists.

Given the Sony’s superior features, I find the price difference reasonable, reflecting performance gains in sensor, autofocus, video, and versatility.
