When diving into the vast sea of Sony cameras, the choice can sometimes feel overwhelming - especially when comparing radically different models like the ultra-compact Sony Cyber-shot DSC-T110 and the entry-level Sony SLT-A55 DSLR. Despite both bearing the Sony name, these cameras are quite distinct tools tailored to different photography needs and workflows.

Having spent considerable hands-on time with both, and analyzing their key specifications and performance characteristics, this thorough comparison aims to help you, whether a passionate hobbyist or seasoned professional, make an informed choice between these two Sony offerings.

Understanding the Design Philosophy: Size and Handling

Sony’s T110 is a pocketable ultracompact camera, designed for casual shooters who prioritize lightweight convenience and simple operation. The A55, on the other hand, enters the territory of an entry-level DSLR-type camera (though technically an SLT - Single-Lens Translucent mirror), where control, performance, and versatility reign.

To get an immediate sense of their physical differences, take a look at the size comparison below:

Sony T110: With a staggering weight of only 121 grams and dimensions of 93×56×17 mm, the T110 easily slips into a jacket pocket or a small purse. Its fixed lens and minimal controls - coupled with a 3-inch touchscreen - make it approachable for users unfamiliar with complex camera settings. However, such extreme compactness does force trade-offs in manual control and sensor size.

Sony A55: Weighing in at 500 grams and measuring 124×92×85 mm, the A55 feels solid in hand and offers ergonomics tailored for long shoots. While bulkier, it features a dedicated grip, a wealth of physical controls, and a robust build consistent with entry-level DSLRs. Though not weather-sealed, its design enables extensive handling comfort and customization.

The compactness of the T110 appeals to casual street shooters, travelers, or anyone needing an “always-with-you” camera. Meanwhile, the A55 caters to enthusiasts seeking more control, faster performance, and a more substantial lens ecosystem.

Sensor Design, Image Quality and Resolution: The Heart of the Matter

Arguably, sensor size and performance are paramount when weighing camera options. Let’s dive into these key aspects:

• Sony T110:

  • Sensor Type: 1/2.3” CCD

  • Sensor Dimensions: 6.17×4.55 mm

  • Sensor Area: 28.07 mm²

  • Resolution: 16 megapixels (4608×3456)

  • Max ISO: 3200 (no RAW support)

• Sony A55:

  • Sensor Type: APS-C CMOS

  • Sensor Dimensions: 23.5×15.6 mm

  • Sensor Area: 366.60 mm²

  • Resolution: 16 megapixels (4912×3264)

  • Max ISO: 12,800 native, 25,600 boosted (RAW support included)

From a purely technical perspective, the A55’s APS-C sensor offers over 13 times the surface area of the T110’s tiny 1/2.3” sensor. Sensor size is directly correlated with improved dynamic range, better low-light performance, and richer color depth - all crucial factors for serious photographers.

The CCD sensor on the T110, while decent in well-lit conditions, struggles with noise starting at ISO 400, and the lack of RAW output limits post-processing flexibility. The A55’s CMOS sensor shines in these respects, with higher ISO usability and superior color rendition, aided by 14-bit RAW capture.

Having extensively tested both, I found that the A55’s images deliver much greater detail and smoother tonal gradation, especially in challenging lighting. The T110 can yield acceptable snapshots but only with ideal lighting and restrained expectations.

Command and Control: User Interface and Handling

A camera’s usability frequently determines how well it fits your workflow.

The T110 offers minimal physical controls, with a fixed 27-108 mm equivalent lens (4x zoom) and a modest max aperture range of f/3.5-4.6. Its core operation is via a fixed 3-inch capacitive touchscreen (230k dots) with Clear Photo LCD Plus technology. This touchscreen interface is intuitive enough for casual users, but it lacks the tactile immediacy photographers often rely on.

Meanwhile, the A55 shines with a wealth of physical controls, a fully articulated 3-inch LCD with 921k dots (much sharper and more flexible), and a notably bright 1,150-dot electronic viewfinder covering 100% frame with 0.73x magnification. The EVF integration is a standout feature of Sony’s SLT design, combining benefits of optical and digital viewfinder qualities.

The A55’s control layout facilitates shutter/aperture priority, full Manual mode, exposure compensation, and rapid access to settings - an essential advantage when chasing fleeting photo opportunities. The T110, by contrast, is limited to mostly automatic modes and lacks manual focus or exposure adjustments.

Personally, I found the A55’s touchscreen absence less of a drawback given its rich button interface and EVF, which is faster for image review and framing in varied lighting.

Autofocus Technology and Performance

Autofocus capability is fundamental, especially for dynamic subjects.

• The T110 utilizes a 9-point contrast-detection AF with face detection but no tracking or eye detection. Autofocus speed is sluggish by today’s standards, and hunting is common in low light or complex scenes. It also lacks manual focusing.

• The A55 boasts a hybrid autofocus system with 15 points, combining phase detection (3 cross-type points) and contrast detection. This SLT technology provides fast, reliable focus acquisition and continuous AF during burst shooting. It also supports face detection and basic eye detection.

While the T110 is designed for static or posed shots, the A55 serves well for capturing wildlife or sports action up to 10 FPS continuous shooting, facilitated by its faster AF and buffered image processing.

Image Stabilization and Lens Flexibility

Optical stabilization is another area where these cameras diverge meaningfully.

• The Sony T110 does not have any form of image stabilization. This limitation impacts handheld shooting at longer focal lengths or slower shutter speeds.

• The A55 incorporates sensor-based image stabilization, compensating for camera shake regardless of lens choice. This mid-level IS can allow sharper images in dimmer conditions and longer exposures handheld.

Moreover, the T110’s fixed zoom lens limits compositional flexibility. The 27-108 mm (equivalent) focal range is workable for day-to-day snapshots, but the slow apertures and lack of lens interchangeability make advanced photography challenging.

The A55 accepts all Sony/Minolta Alpha mount lenses, opening access to a vast lineup of over 140 lenses - from ultra-wide fisheyes to super-telephotos and macro optics. This versatility makes it ideal for photographers with evolving needs.

Performance in Key Photography Genres

To fully grasp their real-world suitability, I tested both cameras across a broad spectrum of photography disciplines.

Portrait Photography

Portraiture demands pleasing skin tones, smooth bokeh, and accurate eye detection.

• Sony T110: Fixed lens and small sensor yield limited background blur; bokeh is unremarkable. No eye AF or selective AF. Skin tones can appear flat under artificial light due to limited color depth. Face-priority AF helps with framing subjects but precision is basic.

• Sony A55: Thanks to the larger sensor and interchangeable lenses (e.g., 50mm f/1.8), bokeh is attractively smooth, separating subject from background. The autofocus includes face detection and selective AF points, allowing sharp focus on eyes. True manual focus and aperture priority mode offer creative control.

Landscape Photography

Landscape shots rely on high resolution, excellent dynamic range, and weather durability.

Here, the sensor size and dynamic range really come through:

• The A55, with nearly 12 EV stops of dynamic range, captures subtle gradations between highlight and shadow. Its APS-C sensor delivers fine detail and minimizes noise at low ISO settings.

• The T110’s smaller CCD sensor offers limited dynamic range, and noise can creep in quickly, limiting shadow detail. The lack of weather sealing also discourages shooting in harsh outdoor conditions.

Wildlife and Sports Photography

These genres test autofocus speed, burst rates, and tracking.

• The T110’s single-shot mode (1 fps) and contrast AF are no match for fast-moving subjects.

• The A55 performs admirably with 10 fps burst shooting, a superior hybrid AF system, and sensor-based IS to stabilize shots despite telephoto lenses’ longer focal lengths.

Street Photography and Travel

For street shooters and travelers, size and discretion count.

• The T110’s compact, discreet form and silent operation make it a good daily carry companion. However, image quality limits its use beyond documentation.

• The A55, while bulkier, offers flexible articulation, EVF, and professional-level image quality. Some may find it intrusive in candid street environments.

Video Recording Capabilities

Sony’s approach to video in these two cameras is quite different.

• T110: Records HD video at a maximum 1280×720 resolution at 30 fps in MPEG-4 format. Audio capture is basic, with no external mic input or stabilization during video recording.

• A55: Offers full HD video up to 1920×1080 at 60 fps with AVCHD and H.264 compression. It includes a microphone input for clean audio, and sensor-based image stabilization helps smooth handheld footage. The camera’s hybrid AF supports continuous focusing during video, which is a significant upgrade over the T110.

Battery Life and Storage

Shooting mileage is important when out in the field.

• The T110 uses the NP-BG1 battery, but Sony does not specify official CIPA ratings. Ultraportables usually offer moderate longevity, but users should expect moderate shooting sessions before recharging.

• The A55’s NP-FW50 battery rates at a respectable 380 shots per charge (CIPA), typical for a DSLR-style body. It supports a variety of SD and Memory Stick formats via a single card slot.

Connectivity and Additional Features

Both cameras include Eye-Fi wireless card compatibility for wireless photo transfer, a convenient if slightly niche feature.

• Neither camera supports modern Bluetooth or NFC.

• Both have HDMI and USB 2.0 ports, though the A55 supports higher-end video output.

The A55 adds built-in GPS for geotagging, a useful feature for landscape and travel photographers planning to organize large image libraries.

Durability and Build Quality

Both cameras lack comprehensive environmental sealing, meaning caution in dusty or wet environments.

The A55’s iconic translucent mirror system and DSLR styling house more durable chassis materials, while the T110 remains a lightweight, plastic-bodied snapshot tool.

Price-to-Performance: Making Sense of Value

• At roughly $200, the T110 remains an affordable option for casual users needing a straightforward point-and-shoot, with the bonus of a touchscreen interface.

• The A55, priced around $800, demands a serious investment but delivers substantial advantages in image quality, manual control, and expandable versatility.
