Olympus SZ-15 vs Sony Cyber-shot TX55: A Hands-On Compact Camera Comparison for Enthusiasts

When it comes to compact cameras that promise versatility without the bulk of DSLRs or large mirrorless systems, the Olympus SZ-15 and Sony Cyber-shot TX55 are intriguing contenders. Both were announced in the early 2010s, targeting casual users and photography enthusiasts craving a balance between zoom reach, image quality, and portability. But how do these two fare when the rubber meets the road? Which one is better suited for your particular photographic adventures?

Having personally tested a wide range of small sensor compacts over the years, including these two, I’ll walk you through their real-world strengths and compromises. We’ll break down usability, imaging performance, features, and finally, make sense of who should consider which camera based on their style and needs.

Let’s dig in.

Getting a Feel: Design, Size, and Handling

First impressions matter, and no matter how good the specs, if a camera feels awkward in hand, it quickly loses appeal.

The Olympus SZ-15 is a bit of a chunkier compact, often referred to as a “superzoom” due to its substantial 21x optical zoom lens. Physically, it measures 108×70×40 mm and weighs around 250 grams. In contrast, the Sony TX55 is ultra-svelte, at just 93×54×13 mm and 109 grams - not much heavier than a modern smartphone.

Sliding these cameras into your bag or jeans pocket leads to wildly different experiences. The SZ-15 feels more like a traditional camera with a comfortable grip and buttons spaced for one-handed operation, even if your hands are on the larger side. The TX55’s ultra-compact slate design is impressive for grabbing shots on the fly and slipping into tight spaces, but the diminutive size can make stable shooting a little more challenging - something I noticed during extended handheld shooting sessions.

Flip them over, and the control layouts also speak volumes about their targeted user experience.

The ZX-15 markets itself as a step-up compact with dedicated dials for aperture and shutter priority modes. Olympus included a modest but tactile mode dial and a nicely placed zoom lever that feels durable. On the other hand, the TX55 sticks to a minimalist approach - not surprising given its slender body - with fewer physical controls but benefits from a touchscreen interface that I’ll touch on shortly.

Peeking Inside: Sensor Technology and Image Quality

Both cameras use the same sensor size: a 1/2.3-inch (6.17×4.55 mm) sensor area with a 16-megapixel count. That's quite common in compacts of this era, balancing resolution and noise performance on a small chip.

However, what sets them apart is the sensor technology. The Olympus SZ-15 employs a CCD sensor, while the Sony TX55 uses a more modern back-illuminated CMOS (BSI-CMOS) sensor. This is a critical technical difference.

From my lab tests and real-world experience, BSI-CMOS sensors tend to excel in better low-light sensitivity and higher dynamic range compared to CCD counterparts. The Sony’s sensor architecture allows it to capture cleaner images at higher ISOs, with less noise and crisper detail retention - especially noticeable beyond ISO 800.

Both cameras max out at ISO 3200, but the Olympus SZ-15’s CCD sensor shows more noise and muted colors in low light or shadow areas. When pushing the contrast or under mixed lighting - think indoor events or sunset portraits - the TX55’s sensor consistently delivers richer tonal gradations.

Neither camera supports RAW capture, which is slightly disappointing for expat photographers looking to extract as much image latitude as possible. You’ll be working with JPEGs directly - so their in-camera processing pipelines matter even more.

Screen Time: Viewing, Live View, and Touch Interfaces

Framing your shot accurately is as much about the screen or viewfinder quality as the imaging core.

Both cameras rely solely on LCD screens; neither have electronic viewfinders (EVFs), a cost-saving choice common in compact shooters.

The Olympus features a 3-inch fixed LCD with 460k dots. It’s adequate - bright enough for most daylight conditions but struggles under strong sunlight, which means finding shade or covering the screen is sometimes necessary.

Sony, ever the display pioneer, impresses here. The TX55 sports a larger 3.3-inch OLED touchscreen with a whopping 1230k dots - almost three times the resolution of the Olympus LCD. The extra resolution and OLED’s superior contrast make composing or reviewing images a joy. Plus, touchscreen responsiveness means faster menu navigation and quick zoom or focus point adjustments. For someone used to smartphone-style interaction, this is a significant usability boost.

That said, focusing via touchscreen isn’t supported (tapping the screen to select focus) on the TX55, which was a rare limitation considering the year it was released.

Autofocus and Shooting Responsiveness

I’ll admit - when I press the shutter release, I want results fast and accurate. This is where the Olympus SZ-15 and Sony TX55 diverge in interesting ways.

Both cameras employ contrast-detection autofocus with face detection features, but the implementation and focus point counts differ.

• Olympus SZ-15: Supports single AF, continuous AF, tracking AF, and face detection. However, the number of focus points is unspecified, and the focusing can feel sluggish, especially at the long end of its zoom lens (483mm equivalent). I noticed hunt-heavy focusing indoors or low contrast scenes, resulting in missed shots during fast action.

• Sony TX55: Features 9 focus points and contrast AF with center and multi-area options. It lacks face detection, which is a curious omission. Nonetheless, thanks to Sony’s BIONZ processor and optimized algorithms, overall focus acquisition was noticeably snappier. Although tracking AF isn’t implemented, the initial lock-on speed felt quicker - critical for grab shots or street photography.

Both cameras shoot at 10 frames per second in burst mode, but the usable length of these bursts is limited by buffer size and write speed. Neither impresses for sustained sports or wildlife action sequences.

Zoom Lenses: Reach and Optical Performance

Let’s address the elephant in the room - zoom range. These cameras cater to completely different needs here.

The Olympus SZ-15 boasts a monumental 21x zoom lens, covering 23mm wide to 483mm telephoto (35mm equivalent). This makes it an obvious choice for travel photographers who want one lens to do it all - from sweeping landscapes to distant wildlife.

The Sony TX55’s zoom is more modest: 26-130mm equivalent, roughly 5x optical zoom. It’s better suited for everyday snapshots, street scenes, and portraits, rather than bird-watching or distant sports.

Now, maximum aperture ranges matter. Olympus’s lens opens wide at F2.8 on the wide end, but closes to F5.9 tele, introducing naturally less light and shallower depth of field control at longer focal lengths. Sony starts narrower at F3.5 wide and goes to F4.8 tele.

What’s this mean in practice? The SZ-15’s longer zoom is wonderful for reach but expects softness and chromatic aberration at full telephoto lengths unless you stop down or stabilize carefully. The Sony’s shorter zoom has better overall sharpness consistency and less optical distortion, though it can’t zoom as far.

Image Stabilization and Low-Light Handling

Both cameras include optical image stabilization (OIS), a must-have with long zooms and smaller sensors to combat blur.

Olympus uses “optical” stabilization (details unspecified but likely lens-shift based), and Sony employs their SteadyShot optical solution.

During my testing, both performed admirably handheld at slow shutter speeds - allowing me to get blur-free shots at around 1/15s for wide angles. Olympus’s 21x zoom combined with stabilization felt solid but at max telephoto the system struggled a bit, making a tripod advisable for sharp shots above 200mm equivalent.

Sony’s more modest zoom and superior sensor meant cleaner, steadier photos in ambient low light. Thanks to the BSI-CMOS sensor’s better noise handling and brighter OLED screen, I found the TX55 easier to shoot at night or indoors. The Olympus’s max native ISO of 3200 was usable only in well-lit settings, beyond that noise quickly crept in.

Flash, Burst, and Shutter

Both models have built-in flashes with ranges of about 3.5 to 3.7 meters. The Olympus provides more flash modes (Fill-In, Red-Eye Reduction, Slow Sync) compared to Sony’s basic Auto, On, Off, and Slow Sync. Red-eye is less of an issue these days, but I appreciate having more flash control.

Both cameras offer continuous shooting up to 10fps, but again buffer limits reduce the practical burst length. Olympus allows manual exposure control with aperture priority, shutter priority, and manual modes - great for more advanced users wanting to fine-tune exposure. Sony restricts users to program modes with no manual exposure, frustrating for photographers wanting deeper control.

Shutter speed ranges differ: Olympus from 1/8s to 1/2000s, Sony from 1/30s to 1/1600s. Olympus offers slightly faster shutter max speed and slower minimum speed, facilitating long exposure and creative blur control.

Video Capabilities: Which Captures the Action Better?

Both cameras shoot Full HD 1080p video, but the frame rates and codecs tell a subtle story.

• Olympus SZ-15: 1080p at 30fps, using AVI MPEG4 and Motion JPEG formats. Lacks 60fps options, so slow-motion footage isn’t smooth.

• Sony TX55: Supports 1080p at 60fps, plus various other resolutions, codecs including MPEG-4 and AVCHD. The higher frame rate enables smoother motion capture and limited slow-motion playback, a small win for video enthusiasts.

Sound recording is limited on both - neither has microphone or headphone jacks, meaning audio quality often comes down to the internal mic with ambient noise capture.

Neither camera offers advanced video stabilization or 4K recording, but Sony’s 60fps mode and superior sensor make its videos look sharper and cleaner overall.

Special Features and Connectivity

Both cameras offer built-in Wi-Fi or similar wireless solutions, but again implementation differs.

The SZ-15 includes built-in GPS to geotag photos - a feature useful for travelers who want automatic logging without extra gadgets. The TX55 relies on Eye-Fi card compatibility to transfer images wirelessly, which is a bit clunkier.

The Olympus uses a proprietary SLB-10A battery, whose life isn’t officially rated but in my testing delivered moderate shooting - enough for a day of casual use with periodic recharging.

Sony’s NP-BN battery officially provides about 250 shots per charge, somewhat limiting for prolonged shooting days.

Storage-wise, both accept SD cards, although the Sony supports microSD and Memory Stick Micro formats - Sony’s proprietary format which most users will likely skip in favor of SDHC/SDXC cards.

Putting the Cameras to Work: Performance by Photography Genre

Photography isn’t one size fits all, so let’s unpack how these two compacts behave across different styles, based on my hands-on evaluations.

Portrait Photography

Portraits require flattering skin tones, smooth bokeh, and reliable eye detection autofocus.

• Olympus SZ-15: Thanks to the 21x zoom with a moderately wide aperture of F2.8 at 23mm equivalent, you can get decent subject separation, but the small sensor limits bokeh quality - background blur is somewhat artificial and highlights can border on harsh. The face detection AF is solid but not lightning fast. Skin tones are warm but sometimes oversaturated.

• Sony TX55: Shorter zoom and narrower apertures limit bokeh, but the sensor’s better dynamic range preserves skin tones more naturally. Lack of face detection slows focus acquisition on portraits, but OLED display helps accurate framing.

Winner: Slight edge to Olympus for compression and subject isolation at long zooms, but Sony provides more pleasing tonality.

Landscape Photography

Landscape shooters prize high resolution, dynamic range, color accuracy, and weather sealing (if available).

• Olympus SZ-15’s 16MP CCD sensor delivers decent detail in ample light but lacks the uplift in dynamic range seen in Sony’s BSI-CMOS sensor. No weather sealing limits outdoor toughness.

• Sony TX55 renders landscapes with richer contrast and better shadow detail. The wider screen and sharper display enable composition refinement in the field.

Since neither camera has environmental sealing, neither is ideal for rugged landscapes - but SX-15's longer zoom is less relevant here.

Wildlife and Sports Photography

Action and wildlife demand fast, accurate autofocus and rapid burst shooting.

Neither camera is a sports specialist, but Olympus’s longer zoom is better suited for distant subjects.

However, its sluggish AF and limited tracking capacity mean many shots will be misses with moving animals or athletes.

Sony’s faster AF acquisition helps at closer ranges but zoom limits reach.

Street and Travel Photography

Compactness, discretion, and versatility rule here.

Sony TX55’s tiny size, light weight, and touchscreen interface shine in street and travel photography. It’s easy to whip out, frame, and fire off shots discreetly.

Olympus SZ-15 is bulkier but versatile thanks to the zoom reach and manual controls, better for travelers willing to carry a dedicated camera with advanced options.

Macro and Close-Up

The Olympus SZ-15 offers a minimum focus distance of 5 cm; Sony’s is 3 cm. Both allow respectable macro shots for compact cameras but struggle to deliver the magnification and sharpness of dedicated macro lenses.

Night and Astrophotography

Both cameras are hamstrung by small sensors and noisy high ISO performance.

Sony’s sensor is more effective in low light, allowing cleaner images at ISO 800–1600.

Neither offers bulb mode nor long exposure aids, so astrophotography efforts are limited.

• Go with Olympus SZ-15 if:

  • You want a long zoom range for versatile shooting and occasional wildlife or telephoto needs.
  • You appreciate manual exposure controls and more flash modes.
  • You don’t mind carrying a slightly bulkier, DSLR-like compact.
  • GPS geotagging is important on your trips.
  • Your focus is more on photographic exploration than ultra-sleek portability.

• Choose Sony TX55 if:

  • Portability, pocketability, and touchscreen operation matter the most.
  • You favor a sharper, more vibrant display for composing and reviewing photos.
  • You want better low-light performance and smoother video with 60fps capability.
  • You primarily shoot street, travel, or casual everyday moments and prefer speed over reach.
  • You can live without manual exposure controls.

Closing Note on Practical Usage

Both cameras show their age in some respects, especially compared to modern smartphones and mirrorless systems. Still, for their era and category, they embody two distinct philosophies: Olympus aims for “all-in-one, feature-rich superzoom,” while Sony pursues “sleek, easy-to-use, superior screen quality.”

If you’re after a straightforward compact with excellent screen and quick autofocus for social outings and casual travel, the Sony TX55 remains a charming choice. On the other hand, if telephoto versatility and manual control tick your boxes on a budget, the Olympus SZ-15 deserves careful consideration - just temper expectations on sensor noise and AF speed.

I hope this deep dive helps you navigate the subtle but meaningful differences between these two vintage compacts, backed by hands-on trial, technical breakdowns, and lots of shooting tales.

Happy shooting!
