Sony A290 vs Sony TX55: An Expert Comparison for Every Photographer

Choosing a camera is a deeply personal decision, shaped by your photography goals, shooting style, and budget. With dozens of models from the same brand, it can be tempting to zero in on specs alone. But as someone who has handled thousands of cameras over 15 years, I can tell you firsthand that the best camera for you isn’t always the one with the newest features or highest resolution. It’s the one that truly fits your needs from the sensor to the ergonomics to the lens ecosystem.

Today, I’m going deep on two very different Sony cameras: the Sony Alpha DSLR-A290, an entry-level DSLR from 2010 targeted at budding enthusiasts, and the Sony Cyber-shot DSC-TX55, a 2011 ultra-compact point-and-shoot designed for everyday portability. These two cameras occupy opposite ends of the spectrum in both design and use case, yet comparing them head-to-head reveals some unexpected insights.

Let’s dissect how they stack up across technical performance, real-world usability, and specific photography disciplines to help you decide where each shines - and where compromises emerge.

Handling & Design: Bulk vs. Pocketability

The A290 commands attention with its classic DSLR stature - measuring 128 x 97 x 86 mm and weighing 549 grams. This is a compact SLR but still firmly in DSLR territory with a robust grip, prominent control dials, and a reasonably solid build. Holding it, you feel the confidence that comes from a substantial camera body designed for semi-professional handling.

By contrast, the TX55 is an ultra-compact powerhouse, tipping the scales at just 109 grams and measuring a sleek 93 x 54 x 13 mm. This is the kind of camera you can slip into a jacket pocket effortlessly. The trade-off? It feels more like an everyday gadget than a precision tool.

Ergonomically, the A290 offers dedicated buttons for shutter priority, aperture priority, manual exposure, and exposure compensation. This hands-on physical control is a boon in fast-paced shooting - you know exactly where everything is without digging through menus.

The TX55’s interface relies heavily on its touchscreen OLED display, foregoing many physical buttons in favor of simplicity and speed for casual shooting. It also offers touchscreen manual focus, a surprisingly sophisticated feature for a camera in this class, but lacks traditional exposure controls.

If photography is a tactile experience that demands precision and familiarity, the A290 wins hands down. For quick snapshots on the go - especially travel or street photography - the TX55’s convenience and compactness will appeal.

Viewfinder & Screen: Optical Clarity or Vibrant OLED?

Looking through the Sony A290’s optical pentamirror viewfinder feels immediate and immersive. Although it covers about 95% of the frame and offers a 0.55x magnification (typical for entry-level DSLRs), I found it accurate enough for framing and focusing. For those who prefer traditional composition, this viewfinder is invaluable, especially in bright daylight where LCDs tend to wash out.

The TX55 abolishes the optical viewfinder entirely. Instead, it boasts a 3.3-inch fixed, XtraFine OLED screen with a very high resolution of 1230k dots, which makes reviewing images and navigating menus a pleasure. In low-light situations, OLED’s contrast advantage is evident, offering richer blacks and brighter colors than an LCD can.

However, relying solely on screens can be tricky in bright outdoor conditions, where glare sometimes inhibits visibility. The A290’s optical viewfinder mitigates this problem, offering a constant, glare-free view.

Interestingly, the A290’s 2.7-inch LCD is fixed and considerably lower resolution (230k dots). While serviceable for basic image review, it pales next to the TX55’s vibrant display quality.

So: traditionalists and controlled shooting environments lean A290, while casual shooters and vloggers will appreciate the TX55’s slick OLED screen.

Sensor Technology & Image Quality: CCD vs. BSI-CMOS

At the heart of any camera is its sensor, and here lies a critical divergence. The Sony A290 uses a 14MP APS-C sized CCD sensor measuring 23.5 x 15.7 mm. This larger sensor physically captures more light than typical compacts, resulting in better image quality, dynamic range, and low-light performance. CCDs - though older technology - are known for their excellent color depth and natural skin tones, which is a boon for portrait work.

The TX55 employs a 16MP 1/2.3-inch BSI-CMOS sensor, just 6.17 x 4.55 mm in physical size. This tiny sensor limits detail and introduces more noise at high ISO, but benefits from the efficiency and speed of back-illuminated CMOS design, which enables features like 10fps burst shooting and 1080p video.

The practical implication? The A290’s sensor produces cleaner images with greater tonal richness and dynamic range, especially in challenging lighting, thanks to its 11.5 EV dynamic range and color depth rating of 22.6 bits (per DxOMark testing). The TX55, with a smaller sensor, naturally exhibits more noise when you push ISO beyond 400.

Landscape photographers and portrait shooters will greatly appreciate the A290’s superior image fidelity. For snapshots, travel, and casual shooting with good lighting, the TX55’s sensor is perfectly adequate.

Autofocus Systems: Precision vs. Flexibility

The A290 incorporates a 9-point phase-detection autofocus (AF) system, a DSLR staple offering speed and repeatability, particularly in daylight. It includes face detection but lacks more modern innovations like eye-detection or animal eye-AF. Continuous AF mode is supported but limited.

In practice, this means the A290 can lock focus reliably for static subjects and casual action with decent accuracy but will struggle with fast-moving targets or complex scenes compared to newer AF systems.

The TX55 uses a 9-point contrast-detection AF with touchscreen targeting, which tends to be slower and less confident in low light but benefits from simplicity and accuracy in close-up and macro shooting. However, its AF isn’t continuous - only single shot focus.

If you prioritize wildlife or sports photography with moving subjects, the A290’s phase-detect AF is a better tool. For macro, street, and travel shots in good light where speed is less crucial, the TX55’s AF will suffice.

Shooting Experience Across Disciplines

Portraits: Skin Tone Rendering & Subject Isolation

With its APS-C CCD sensor and lens mount supporting over 140 lenses, the Sony A290 is a capable portrait camera - if paired with a fast prime or zoom offering wide apertures, you’ll get pleasing bokeh and fine detail.

The A290’s color depth and gradation yield flattering, natural skin tones. Eye detection AF, while basic, does help keep faces sharp, though not at the level of modern AI-driven systems.

The TX55, constrained by a small sensor and fixed lens with max aperture F3.5-4.8, produces images with shorter depth of field and less subject isolation. Skin tones tend to look flatter and less nuanced. Portrait mode software is relatively basic.

Landscapes: Detail & Dynamic Range

Here the A290’s larger sensor shines, resolving fine textures and handling high-contrast scenes with grace. Its dynamic range of 11.5 stops allows you to retain highlights and shadows in challenging conditions, essential for dramatic landscapes.

Despite lacking weather sealing, its body and lens ecosystem are rugged enough for most amateur outdoor use.

The TX55, with its limited sensor and narrower dynamic range, can produce decent landscapes but images often require post-processing to enhance shadows and highlights. The small sensor limits ultimate resolution in large prints.

Wildlife & Sports: AF Speed and Burst Performance

The A290 offers 3fps continuous shooting and phase-detect AF, adequate for casual wildlife and sports photography but lacking the speed and tracking capabilities of more modern cameras.

The TX55 shines in burst speed with 10fps continuous - though limited by slow contrast-detect focus and small sensor - making it reliable for fast-camera shutter button mashing rather than precise tracking.

Neither camera suits professional sports photographers, but for enthusiasts, the A290 feels more versatile.

Street & Travel: Discretion and Portability

The TX55 is the clear winner for urban photography and travel, enabling candid shots with its pocket-friendly profile and near-silent operation. Its touchscreen makes quick adjustments on the fly easy.

The A290’s size and shutter noise make it more conspicuous and less suitable for unobtrusive street shooting, although it offers superior image quality when discretion is less critical.

Battery life - 290 shots on the A290 versus 250 on the TX55 - is similar but both cameras benefit from carrying spares for long outings.

Macro & Close-Up

The TX55 allows focus as close as 3cm with optical stabilization - great for casual macros. The touchscreen AF helps nail focus on small subjects.

The A290 lacks a specified macro focusing range but enables macro shooting with compatible lenses. Its sensor and lens options deliver sharper, higher quality close-ups.

Night & Astro Photography

Although not a dedicated astro camera, the A290 has ISO up to 3200 and benefits from a larger sensor that produces cleaner images at higher ISOs. Exposure modes including aperture priority and manual controls allow long exposures necessary for astro.

The TX55’s max shutter speed is only 1/1600 sec but it lacks full manual controls and raw capture; noise at high ISO kills long exposure potential.

Video Capabilities: DSLR vs. Point-and-Shoot

The A290 offers no video recording - common for DSLRs of its time but a clear limitation today.

In contrast, the TX55 records 1080p video at 60fps in AVCHD and MPEG-4 formats. Optical image stabilization improves handheld video quality, and the OLED screen aids in framing. However, there are no microphone or headphone jacks, limiting audio control.

For casual videographers, the TX55 suffices, while serious video shooters should look elsewhere.

Lens Ecosystem & Compatibility

One of the A290’s biggest strengths is its Sony/Minolta Alpha bayonet mount supporting a vast range of over 140 native lenses, including fast primes, specialized macro, zooms, and third-party options. This flexibility is invaluable for photographers who want to experiment and grow.

The TX55’s fixed 26-130mm equivalent zoom lens limits versatility but covers a useful general-purpose range for travel and day-to-day shooting.

Connectivity & Storage

Neither camera boasts advanced wireless features like Bluetooth or NFC. The TX55 includes Eye-Fi card compatibility - effectively wireless SD cards - for convenient image transfer, which could be a lifesaver on the go.

Storage options differ: the A290 takes standard SD/SDHC and Memory Stick Duo cards, while the TX55 uses microSD and Memory Stick Micro cards. Battery types differ as well, reflecting their era and form factor.

Performance Summary & Recommendations

Let’s break down the conclusions drawn from hands-on testing, imaging science, and field use.

Who Should Buy the Sony A290?

If you are an amateur enthusiast craving the DSLR experience, the A290 delivers particularly well-rounded image quality, manual control, and an expandable lens system for exploring different genres from portraits and landscapes to wildlife and macro.
