Pentax's XG-1 employs a bridge camera design, typically characterized by a larger body resembling a DSLR, but with integrated zoom lenses. In contrast, Sony’s T90 is a minimalistic ultracompact, prized for easy portability.

At 119 x 89 x 98 mm and weighing 567 grams, the XG-1 offers a substantial grip that enhances stability, particularly when shooting at extended focal lengths. The pronounced handgrip and substantial depth afford photographers confident handling, making it a feasible tool for longer shooting sessions and telephoto work without excessive fatigue.

The T90’s extraordinarily petite 94 x 57 x 15 mm dimensions and featherweight 148 grams invite effortless carry and arguably superior discretion for street photography or travel. However, the slimmest form factor compromises grip comfort and reduces physical controls for quick access to important settings.

Control Layout and User Interface

The bridge style XG-1 favors dedicated dials and buttons enabling direct manual control of exposure settings, a significant advantage for enthusiasts accustomed to DSLR-style workflows. This includes full shutter priority, aperture priority, and manual exposure modes, alongside exposure compensation and custom white balance.

Conversely, the T90 offers a streamlined interface, with touchscreen functionality aiding in menu navigation, albeit with limited manual exposure options - effectively none - and reliance on automation. While the touchscreen introduces modern ease-of-use, it lacks the nuanced control manual shooters desire.

The XG-1’s electronic viewfinder (EVF), despite modest 200-pixel resolution, supplies an invaluable alternative to the rear LCD under bright outdoor conditions - a feature completely absent on the T90, which relies solely on a 3” fixed LCD with a modest 230k dot resolution. This affects framing precision and image review in certain lighting scenarios.

Imaging: Sensor Technology, Image Quality, and Lens Mechanics

At the heart of any camera lies its imaging module. This section examines sensor size, resolution, ISO performance, and lens systems impacting image fidelity.

Sensor Comparison: Technology and Resolution

Both cameras employ the common 1/2.3-inch sensor format with near-identical 6.17 x 4.55 mm dimensions, though the Pentax XG-1 utilizes a 16-megapixel backside-illuminated (BSI) CMOS sensor, whereas the Sony T90 is based on a 12-megapixel CCD sensor.

BSI-CMOS technology often delivers superior high ISO performance, lower noise, and faster readout speeds compared to CCDs, which favors video and burst shooting. This positions the XG-1 advantageously for low-light or action scenarios, though expectations should remain tempered owing to the small sensor size's inherent limitations in dynamic range and noise.

The Pentax captures images at a maximum resolution of 4608 x 3456 pixels, providing an edge in detail over the T90’s 4000 x 3000 pixel output.

Lens Systems: Versatility vs. Compactness

The XG-1’s lens is a colossal 24-1248 mm equivalent zoom with a 52x optical range and maximum aperture from f/2.8 to f/5.6, a remarkable reach that empowers photographers to frame subjects from wide landscapes to distant wildlife without swapping lenses. Its macro focusing is impressively close at 1 cm, offering versatility in close-up photography.

Sony’s T90 sports a 35-140 mm equivalent lens (4x zoom) with a maximum aperture ranging from f/3.5 to f/10, favoring wide to short telephoto uses but lacking reach for distant subjects. The smaller lens complements the camera’s compactness but limits creative framing for specialized photography such as wildlife or sports.

Performance in Action: Autofocus, Burst Shooting, and Image Stabilization

Camera responsiveness and focusing accuracy are decisive qualities, particularly for dynamic subjects.

Autofocus Systems

The Pentax XG-1 surprisingly provides no phase detection or contrast detection autofocus points, lacking even face detection or tracking. This is a significant shortcoming for a 2014 model, meaning autofocus relies on basic contrast detection algorithms without finely tuned focus zones, possibly leading to hunting and slower acquisition. The absence of continuous autofocus modes restricts its usability for moving subjects.

Sony’s T90 incorporates nine contrast detection autofocus points, with a center-weighted metering and spot focus mode. Its autofocus is limited to single-shot but is comparatively reliable for still subject compositions, aided by the touchscreen to select focus points manually.

Burst Shooting and Shutter Speeds

The XG-1 achieves a respectable 9 fps continuous shooting rate (though buffer depth and autofocus locking may constrain practical use), coupled with shutter speeds from 4 to 1/2000 second allowing for creative control in motion freezing or blur.

Conversely, the T90's burst rate is a modest 2 fps, paired with a shutter range of 1 to 1/1600 second, limiting its proficiency for fast action or sports photography.

Stabilization

Both cameras house image stabilization systems, yet of differing types: Pentax’s sensor-shift stabilization counters camera shake regardless of lens length - a boon for superzoom telephoto use - while Sony’s optical stabilization is lens-based, beneficial but possibly less versatile.
