First Impressions and Handling: Size, Build, and Control Feel
Both the Sony T99 and TX55 belong to the ultracompact class, designed for maximum portability without compromising too much on image quality or feature set. Let’s start by sizing them up physically and seeing how their designs impact usability.
Feature | Sony T99 | Sony TX55 |
---|---|---|
Dimensions (WxHxD mm) | 93 x 56 x 17 | 93 x 54 x 13 |
Weight | 121 g | 109 g |
Build | Plastic chassis, minimal weather sealing | Slightly slimmer, similar build quality |
Control Layout | Touchscreen-enabled, minimal physical buttons | Touchscreen with manual focus ring |
Screen Type | 3.0" fixed, low resolution | 3.3" fixed, XtraFine OLED touchscreen |
Testing both models, the TX55 feels noticeably slimmer and lighter, lending it an edge for pocket carry and discreet street shooting. The T99, though slightly thicker, offers a chunky grip area that can help prevent slipping, valuable during longer shoots or one-handed operation.
The touchscreen responsiveness on the TX55 is more refined, thanks to the OLED panel’s superior contrast and resolution, making liveview framing and menu navigation easier under various lighting conditions.
On top, both cameras keep controls minimalistic. Neither offers dedicated playback, ISO, or exposure mode buttons, keeping the user experience straightforward, but you do get the convenience of touchscreen-enabled focus point selection in both cases.
Summary: If ultralight portability with an excellent screen is your priority, TX55 wins here. But if you prefer slightly better grip feel and don't mind a bit more heft, the T99 remains a solid choice.
Sensor and Image Quality: CCS vs BSI-CMOS, Resolution, and ISO Performance
One of the defining technical differences lies in the sensor technology. The T99 uses a 14-megapixel CCD sensor, while the TX55 boasts a newer 16-megapixel backside illuminated (BSI) CMOS sensor.
Parameter | Sony T99 | Sony TX55 |
---|---|---|
Sensor Size | 1/2.3" (6.17x4.55 mm) | 1/2.3" (6.17x4.55 mm) |
Resolution | 14 MP (4320x3240) | 16 MP (4608x3456) |
Sensor Type | CCD | BSI CMOS |
Max ISO | 3200 | 3200 |
Image Stabilization | Optical | Optical |
Raw Support | No | No |
Technical Insight: The CCD sensor on the T99 was typical in compact cameras around 2010, offering rich color reproduction but with limitations in noise control at higher ISOs. The TX55’s BSI-CMOS sensor improves on this - its backside illumination design increases light-gathering efficiency, enhancing low-light sensitivity and dynamic range despite the same sensor size.
Real-World Testing: In daylight and well-lit indoor shots, image sharpness and color accuracy between both cameras are quite comparable. However, under dim lighting, the TX55 produces cleaner images at ISO 800 and above, with noticeably less color noise and grain.
Regarding resolution, the 16 MP output of the TX55 offers slightly larger image files and more flexibility for cropping, useful for event coverage or modest print enlargements.
Autofocus Systems: Precision, Speed, and Usability Differences
Both cameras employ contrast-detection autofocus systems with 9 focus points and lack phase-detection or hybrid AF. However, the TX55 introduces manual focus control - a rare feature in such a compact model.
AF Feature | Sony T99 | Sony TX55 |
---|---|---|
AF System | Contrast Detect, 9 points | Contrast Detect, 9 points + manual focus ring |
Face Detection | No | No |
Continuous AF | No | No |
AF Speed | Moderate | Slightly improved |
Though both cameras have similar AF speed in bright conditions, low contrast or dim environments reveal the TX55’s algorithms and sensor speed improvements, enabling quicker focus lock. The manual focus option on the TX55 lends creative control, especially useful for macro shots, which the T99 lacks.
Monitoring and Composing Images: Display Technology and Usability
The transition from the T99’s basic 230k-dot LCD to the TX55’s sharp 1230k-dot OLED screen is a significant upgrade.
The TX55’s XtraFine OLED panel provides punchy colors and excellent contrast - meaningful for checking focus, exposure, and framing, especially outdoors. The T99’s screen often looks washed out under bright sunshine, requiring you to shield it or guess composition.
Both cameras lack electronic viewfinders, a typical limitation of ultracompacts, making the screen quality paramount.
Lens Capabilities: Zoom Range and Aperture Impact
Lens specs are always a key consideration. While neither camera supports interchangeable lenses, their fixed zoom range and aperture influence flexibility.
Lens Spec | Sony T99 | Sony TX55 |
---|---|---|
Focal Length (35mm equivalent) | 25-100 mm (4x zoom) | 26-130 mm (5x zoom) |
Max Aperture | f/3.5-4.6 | f/3.5-4.8 |
Macro Focus Range | 1 cm | 3 cm |
The TX55 offers a longer telephoto reach, going up to 130 mm equivalent - helpful for tighter portraits, details, or casual wildlife shots. Though starting focal lengths are similar, this extended zoom adds versatility.
Conversely, the T99 shines slightly in macro photography, capable of focusing just 1 cm from your subject, allowing extreme close-ups. The TX55’s minimum macro focusing distance is 3 cm, still respectable but less intimate.
