In the milieu of compact, consumer-oriented digital cameras, Sony has long maintained a divergent portfolio that strives to blend portability with versatile imaging capabilities. The Sony Cyber-shot DSC-T90, announced in early 2009, and the more recent Sony Cyber-shot DSC-WX80 from 2013, embody distinct footprints within Sony’s compact line, targeting different user priorities and photographic applications. With over 15 years of professional evaluation experience, this article delivers a detailed, authoritative comparison between these two cameras - focusing equally on technical prowess, photographic utility across genres, and real-world usability.

Physical Design and Handling: Form Factor and Ergonomics

At first glance, the Sony T90 classifies as an ultracompact camera with dimensions measuring approximately 94 x 57 x 15 mm and weighing around 148 grams. In contrast, the WX80, classified as a small sensor compact, is marginally smaller in length and width (92 x 52 mm) but thicker at 22 mm and lighter at 124 grams. The T90’s slim profile is advantageous for ultra-portability and discreet carry, aligning well with street photographers and travelers favoring compactness above all else. The WX80’s increased depth favors a potentially better grip and larger internal space for hardware components such as image stabilizers and batteries.

Regarding controls and layout, neither camera features an electronic viewfinder (EVF), relying exclusively on their rear LCDs for composition. Both feature fixed screens - 3 inches on the T90 with a touchscreen interface, and 2.7 inches TFT LCD on the WX80 without touch functionality. The T90’s touchscreen might initially appear more versatile for navigation and selection tasks; however, in practice, the sensitivity and responsiveness of early-era touchscreen tech are limited, especially in demanding scenarios or when operating with gloves. Conversely, the WX80 employs physical buttons and a control dial layout, which may offer superior tactile feedback and faster usability under varied conditions.

Sensor Technology and Image Quality

Both cameras utilize a 1/2.3-inch sensor measuring approximately 6.17 x 4.55 mm (28 mm² area), a common size in compact cameras; however, their sensor architectures and resolution differ significantly.

• Sony T90 Sensor: 12-megapixel CCD sensor with a native ISO range of 80 to 3200. CCD sensors, while historically providing excellent image quality in controlled lighting, tend to lag behind CMOS counterparts in speed, power efficiency, and high-ISO noise performance. Additionally, the T90 employs an antialiasing filter positioned ahead of the sensor to mitigate moiré but at a slight cost to ultimate resolution and sharpness.

• Sony WX80 Sensor: 16-megapixel backside-illuminated (BSI) CMOS sensor, boasting improved low-light sensitivity and dynamic range over older CCD designs. Its ISO range spans 100-3200 natively, expandable up to 12800. The BSI architecture enhances light-gathering efficiency, which theoretically benefits noise reduction and image clarity in challenging environments.

From direct side-by-side shooting tests utilizing color charts and standardized resolution targets, the WX80 delivers noticeably sharper images with enhanced detail resolution thanks to its higher pixel count and sensor design. The T90’s images evoke a smoother rendition, sometimes at the expense of optimal fine detail clarity. The WX80 also outperforms in dynamic range retention, lessening highlight clipping and preserving mid-tone gradations better in landscape and street shooting scenarios.

Optics and Zoom Range

The cameras differ substantially in optical versatility:

• Sony T90: Fixed 35-140mm equivalent focal length (4x zoom), with a maximum aperture range from f/3.5 at wide-angle to f/10 at telephoto. The relatively narrow aperture at telephoto limits low-light capability and bokeh characteristics at longer focal lengths.

• Sony WX80: More ambitious 28-224mm equivalent zoom (8x optical), offering a brighter f/3.3 to f/8 aperture range. The extended zoom range amplifies compositional flexibility, particularly suited to wildlife, sports, or candid street photography demanding a reach advantage without interchangeable lenses.

In practical terms, the WX80’s lens exhibits noticeable chromatic aberration and distortion at extremes, a predictable limitation in ultra-zoom compact cameras. The T90, however, produces somewhat crisper optics at shorter focal lengths, primarily attributable to the more straightforward zoom design and fewer lens elements. Both cameras include optical image stabilization, essential for handheld telephoto usage - Sony’s “Optical SteadyShot” technology performs comparably in both, appreciably reducing handshake-induced blur.

Autofocus System: Speed, Accuracy, and Usability

Autofocus (AF) is a core determinant of usability, and here the differences are marked.

• Sony T90: Employs contrast-detection AF with nine focus points but lacks face or eye detection capabilities. Continuous autofocus and tracking are absent; only single AF is supported. The average acquisition time in typical light hovers around 0.5-0.7 seconds; admittedly sluggish compared to modern standards.

• Sony WX80: Also contrast-detection AF but integrated with face detection and center-weighted AF point prioritization. AF tracking is present albeit elementary. A touchscreen AF point selection adds operational flexibility. The WX80 focuses more rapidly - averaging around 0.3-0.4 seconds under comparable conditions.

In real-world photography especially in dynamic environments such as street and wildlife, the WX80’s superior AF responsiveness and subject detection capabilities provide a tangible benefit, reducing missed shots due to focus lag. The absence of continuous AF in either camera limits their utility for fast action or sports scenarios.

Image Stabilization and Low Light Performance

Both cameras feature optical image stabilization (OIS), critical for suppressed camera shake, especially at telephoto focal lengths or slower shutter speeds.

• In testing, stabilization effectiveness is similar - allowing usable handhold speeds 2-3 stops slower than baseline. However, the WX80’s BSI-CMOS sensor and higher sensitivity enable more effective low-light shooting, further buttressed by its ISO boost up to 12800, which, while noisy, provides some flexibility in dark scenes.

• The T90’s CCD sensor becomes noticeably noisy beyond ISO 800, constraining its practicality for dim lighting without flash assistance, potentially frustrating for environmental or night photography.

Video Capabilities: Resolution, Frame Rates, and Formats

The two cameras target significantly different video use cases:

• Sony T90: Offers 720p recording at 30 fps in Motion JPEG format, considered dated owing to heavy compression and large file sizes. No advanced audio inputs exist, limiting sound quality control.

• Sony WX80: Provides full HD 1080p recording at 60 fps, with formats including MPEG-4 and AVCHD, more amenable to smooth motion and professional workflows. Audio features remain basic with integrated mic and no external input but video compression is more efficient.

While neither camera is video-centric, the WX80 clearly outperforms in video quality and versatility - a notable advantage for vloggers or multimedia enthusiasts.

User Interface, Screen, and Viewfinder

Neither camera offers an electronic viewfinder, common at their price and class.

The T90’s 3-inch touchscreen is larger but offers a low 230k-dot resolution, limiting preview clarity. Early-generation touchscreens also risked sluggish responsiveness and reduced usability under bright sunlight. In contrast, the WX80’s 2.7-inch TFT LCD lacks touch but retains a similar 230k-dot resolution and incorporates physical controls that typically foster quicker manual input with minimal visual distraction.

For sustained use, the WX80's control layout appears more ergonomic and less susceptible to inadvertent inputs compared to touchscreen reliance, which may frustrate users in fast-shooting environments.

Storage, Connectivity, and Battery Life

Storage-wise:
