Olympus VG-145 vs Sony Cyber-shot TX55: A Hands-On Ultracompact Camera Showdown

When sifting through ultracompact cameras, especially models that emerged around 2011, you soon realize how design philosophies diverge massively in this category. Two peers from that era, the Olympus VG-145 and the Sony Cyber-shot TX55, sit at the crossroads of portability and image quality. But which one really delivers when you take them out for a spin in the field? Drawing on my decade and a half experience testing cameras across genres, I’ll break down everything you need to know - from sensor tech to ergonomics, autofocus behavior to video chops, and who stands tall in different photography disciplines.

Let’s get started.

First Impressions and Physical Feel: Size, Build, and Handling

One of the first things you notice when putting the Olympus VG-145 and Sony TX55 side-by-side is their physical footprint - and there’s a subtle but important difference in ergonomics.

The Olympus VG-145 is undeniably tiny, measuring roughly 96x57x19mm and weighing a mere 120g including battery. It fits comfortably in the smallest pockets, though the trade-off is its all-plastic build, which feels more toy-like than premium. For casual snapshots and absolute portability, it excels.

The Sony TX55 is marginally smaller and lighter - about 93x54x13mm and 109g - but where it wins is in a more refined build quality and a slightly tapered body that nestles comfortably in the hand despite its sleek profile. The metal body gives a reassuring heft and durability that makes it a more confident traveler’s companion.

If you value stealth and ultra-portability, Olympus feels like the lightest carry. If you want a tad more robustness and comfort during longer shooting sessions, Sony wins the tactile battle.

Now, let’s dive a bit deeper with a look at their control layout.

Both cameras favor simplicity, lacking extensive dials or external controls; to keep things lightweight, each ideates on minimalism. The Sony’s top plate includes a slightly more intuitive zoom rocker and a dedicated video record button - conveniences Olympus misses. However, Olympus has a physically larger shutter button which some may find magnetically satisfying. Neither offers manual dials or rings, spotlighting their beginner-friendly intentions.

Sensor and Image Quality: The Heart of the Cameras

I always begin image quality reviews with sensor tech because it’s the foundation for every picture you produce.

Here’s where the Sony TX55 has a tangible technical edge:

• Both cameras house a 1/2.3" sensor measuring 6.17x4.55 mm, but Sony uses a modern 16MP BSI-CMOS sensor with a back-illuminated design that improves low-light gathering efficiency.
• Olympus relies on a 14MP CCD sensor, which is generally less efficient in low light and known for higher noise at elevated ISOs.

In real-world shooting, that means the Sony TX55’s images show better dynamic range and cleaner low-light results up to ISO 800 and beyond. Olympus tends to exhibit earlier noise onset and somewhat flatter color tonality, especially in dim conditions.

Sony maxes out sensitivity at ISO 3200, practically usable up to ISO 800, whereas Olympus peaks at ISO 1600 but with a noticeable drop in quality above ISO 400.

For maximum image resolution, the TX55 edges out with 4608x3456 pixels compared to 4288x3216 on the VG-145 - a modest but appreciated bump for those who crop or print larger. Both feature anti-alias filters, which help reduce moiré but can slightly soften fine details.

What about noise and sharpness?

In my studio testing and field trials, the Sony’s BSI-CMOS sensor delivers sharper images with more accurate color rendition and better preservation of highlight and shadow detail. Olympus’ CCD images can feel softer and less vibrant, potentially requiring more post-processing.

Display and Interface: See What You Shoot

Reviewing compact cameras without a viewfinder means LCD performance becomes critical for composing and reviewing shots.

Sony has a clear advantage here: the TX55 sports a 3.3-inch XtraFine OLED touchscreen at 1230k-dot resolution. This OLED panel dazzles with deep blacks, vivid colors, high contrast, and excellent visibility under bright sunlight. The touchscreen interface also simplifies navigation through menus and quick focus point selection - a rare convenience in compacts from this era.

Olympus’ VG-145 sticks to a simpler 3-inch TFT LCD with just 230k-dot resolution, which feels grainy by comparison and struggles under harsh outdoor lighting. Further, it lacks touchscreen capability, meaning you navigate with tiny buttons alone - a slower, less intuitive interface that becomes frustrating during quick shoots.

If you plan to review images extensively on the camera, or want quick touchscreen focus accuracy, the Sony’s display is a major asset.

Autofocus and Shooting Performance: Where Speed and Precision Meet

Ultracompacts traditionally trade speed for size, but autofocus remains key for capturing moments.

The VG-145 employs basic contrast-detection AF with face detection, but no continuous tracking or fine manual focus adjustment. Its focus speed is adequate in bright conditions but noticeably slow and prone to hunting in low light or complex scenes.

Sony TX55 uses a refined contrast-detection AF with 9 focus points and center-weighted metering. While its AF speed isn’t blistering, it’s considerably faster and more reliable than Olympus, especially on subjects near the macro focus range of 3cm, compared to Olympus’s ultra-close 1cm minimum.

Continuous shooting?

Sony supports up to 10 frames per second, impressive for an ultracompact, ideal for faster-paced photography like street or casual sports. Olympus does not specify continuous shooting capabilities, implying no meaningful burst mode.

Neither model offers tracking autofocus or advanced eye detection, so don’t expect pro-level tracking on moving subjects.

Lens Quality and Optical Performance

Both cameras feature a fixed 5x zoom lens covering 26-130mm equivalent focal length, targeting everyday versatility.

• Olympus VG-145 lens max aperture: F2.8-6.5 (brighter wide end)
• Sony TX55 lens max aperture: F3.5-4.8

The Olympus lens starts brighter wide open at f/2.8, which theoretically benefits low light and shallow depth of field - important for portraits or selective focus. However, Olympus’ slower sensor and lack of stabilization limit this advantage.

Sony’s lens may be slower upfront but incorporates optical image stabilization (SteadyShot), helping reduce blur from camera shake, particularly important at telephoto ranges and in low light. Optical stabilization is absent on the Olympus VG-145 entirely.

Image sharpness across the frame fares slightly better on Sony, with less corner softness and chromatic aberration in my lab tests - likely from more modern lens elements and coatings.

Battery Life and Storage Convenience

For travel and extended shooting, battery life and storage options matter a lot.

The Olympus VG-145’s battery (LI-70B) claims about 160 shots per charge, which I found conservative in real use. Sony’s NP-BN battery offers roughly 250 shots, markedly better, making the TX55 a better choice if you won’t have idle time to recharge.

Regarding storage, Olympus uses SD/SDHC cards, while Sony offers flexibility with microSD/SDHC and Memory Stick Micro cards - broader compatibility with microSD cards is a smart touch for ease of access and cost-effectiveness.

Video Recording Capabilities

In 2011, compact cameras started stepping up their video specs, and here, the Sony TX55 clearly pulls ahead.

• Olympus VG-145: Max video resolution of 1280x720 at 30fps, using Motion JPEG format. No microphone port or advanced codecs.
• Sony TX55: Records Full HD 1920x1080 at 60fps in AVCHD and MPEG-4 formats, superior quality and smoothness.

Sony also supports HDMI output, letting you watch videos directly on external displays - a neat feature missing from Olympus.

Neither supports 4K or has advanced audio inputs, so serious videographers should look elsewhere, but Sony is a pronounced step up for casual HD video capture.

Connecting to the Outside World: Wireless and Ports

Connectivity is often overlooked but critical for some shooters.

Neither camera supports Bluetooth or NFC, as was common in 2011, but Sony includes Eye-Fi card compatibility for wireless image transfers if you supply the card separately. This can simplify workflows for quick sharing on the go.

Olympus lacks any wireless features, and both cameras have USB 2.0 for data transfer.

Sony again offers HDMI out; Olympus does not.

Real World Uses: Portraits, Landscapes, and More

Now that we’ve gone through specs and tech, how do these cameras stack up in real-world photography? I put both through varied tests to see how they perform across popular genres.

• Portrait Photography:
  Olympus offers a wider aperture of f/2.8 at 26mm, which can help soften backgrounds slightly, but the lack of image stabilization and noisier sensor limit sharpness and clarity. Skin tones felt a bit flat. Sony’s sharper sensor and stabilized lens create cleaner, more vibrant portraits; however, it uses a smaller aperture meaning slightly deeper depth of field. Neither has eye detection, so focusing requires care.

• Landscape:
  Both cameras face challenges with dynamic range typical to compact sensors. Sony pulls ahead in detail and highlight retention, giving slightly more definition in shadow-rich scenes. Olympus’s colors lean towards neutrality but lack punch. Neither is weather sealed, so protect them accordingly.

• Wildlife and Sports:
  Not the strongest category for these ultracompacts. Sony’s faster AF and 10fps burst give it a marginal advantage on action shots, but both cameras struggle with focus tracking and require very good light. Olympus’s slower AF and no burst mode restrict its use here.

• Street Photography:
  Both models are discreet and portable. Sony’s faster startup, improved AF, and touchscreen interface enable snappier shots. Olympus risks missing moments with slower response.

• Macro:
  Olympus touts a “super-close” 1cm macro, better than Sony’s 3cm. In practice, Olympus’s macro shots deliver fine detail up close, though prone to softness unless handheld very steady. Sony benefits from stabilization but can’t get as close.

• Night and Astro:
  Low light favors Sony heavily here. The BSI sensor and stabilization allow cleaner shots at ISO 800-1600, whereas Olympus noise rises quickly, limiting usability to ISO 200-400 max. Neither camera is ideal for serious astro shooting but Sony can handle casual night scenes better.

• Video:
  Sony’s Full HD 60fps beats Olympus’s 720p 30fps handily, providing smoother motion and better detail.

• Travel:
  Sony’s combination of compact size, excellent battery life, better screen, and wireless connectivity suits travelers nicely. Olympus is almost pocket-friendly but limited by shorter battery life and less versatile imaging.

• Professional Work:
  Neither camera caters to professional workflows - no RAW support, no manual modes, limited controls. These are snapshooters, designed for convenience over craft.
