At a mere 94 x 54 x 20 mm and weighing just 126 grams, the Canon A2400 IS is finely engineered for effortless everyday carry. Its minimalist compact body aligns with typical pocket-friendly designs from Canon’s lineup, making it ultra-lightweight and convenient for casual snapshots, street photography, and travel documentation.

Olympus TG-320: Ruggedness Comes with Size

By contrast, Olympus’s TG-320 measures 96 x 63 x 23 mm, marginally bulkier and heavier at 155 grams, but this extra mass is attributable to its environmental sealing - waterproofing (up to 3m), shockproofing (1.5m drops), freezeproofing (-10°C), and dustproofing. These qualities make it an ideal companion for adventure and rugged outdoor use where weather or accident-proofing outweighs absolute compactness.

Control Layout and Button Accessibility

The control scheme is fairly basic on both cameras but tailored to their target users. The Canon emphasizes straightforward operation with a familiar dial-based mode system and few buttons, suitable for novices who prefer automatic modes augmented by simple manual overrides like exposure compensation. Olympus incorporates pet auto shutter and dedicated underwater scene modes, accessible via tactile buttons with rubberized seals enhancing durability but slightly impacting button travel.

Sensor and Image Quality: Evaluating the Core Photo Performance

Both cameras feature a 1/2.3 inch CCD sensor, a common small sensor standard in early 2010s compacts. However, despite identical physical sensor sizes (approx. 6.17 x 4.55 mm) and areas (28.07 mm²), differences in resolution and processing reflect in output image quality.

Resolution and Detail

• Canon A2400 IS offers a 16MP resolution (4608 x 3456 pixels), which theoretically captures more detail.
• Olympus TG-320 sacrifices some resolution for noise performance with 14MP (4288 x 3216 pixels).

While higher pixel count usually promises finer detail, the resultant image quality here depends heavily on sensor technology and image processing algorithms.

Image Processor and Noise Handling

The TG-320 employs Olympus’s TruePic III+ processor, which, though dated by modern standards, remains notable for improved noise reduction compared to average processors in similar cameras of the era. Conversely, Canon’s processing engine is unspecified but lends itself to the classic PowerShot style of producing more vibrant colors, sometimes at the cost of slightly increased noise in high ISO images.

ISO Range and Low Light

Both cameras have a native ISO range topping at 1600, though practical usability at this ceiling is limited due to pronounced noise common with small sensors. The TG-320's lower minimum ISO of 80, as opposed to Canon’s 100, can help in bright conditions for better dynamic range and cleaner base images.

RAW Support

Neither supports RAW capture, meaning photographers are confined to processed JPEGs straight from the camera, limiting post-processing flexibility - a crucial consideration for professionals or serious enthusiasts looking to maximize image quality.

Autofocus Capabilities: Speed, Accuracy, and Practical Use

Autofocus (AF) performance significantly influences camera versatility across genres, from fast-moving wildlife to intricate macro scenes.

Canon A2400 IS

The Canon features a contrast-detection AF system with 9 AF points, including face detection and basic tracking. Continuous AF is supported, which improves focus reliability during movement, an asset for casual sports or street photography. The AF speed is fast enough for everyday subjects but struggles in low contrast or low light situations.

Olympus TG-320

Olympus also utilizes contrast-detection with unspecified focus points but includes face detection and tracking capabilities. Noteworthy is the sensor-shift optical image stabilization, which compensates for slight shakes during focusing and shooting, marginally improving AF precision for handheld macro or telephoto use.

In practice, the TG-320 exhibits a steadier and more consistent autofocus under variable conditions, especially in waterproof or outdoor scenarios, although it lacks continuous AF (only single AF mode) - a bottleneck for fast action sequences.

Lens Characteristics and Optical Performance

Canon PowerShot A2400 IS - Versatile Zoom Range

The Canon’s fixed lens offers a 28–140 mm (35mm equivalent) focal range with 5x optical zoom and aperture range F2.8–6.9. This range strikes a balance for wide-angle landscapes and mid-telephoto portraits or casual wildlife shots at moderate distances. The bright F2.8 aperture at the wide end benefits indoor or dim environments, delivering better depth of field control and clearer images.

Olympus TG-320 - Compact but Weather Tough

Olympus opts for a shorter 28–102 mm (3.6x zoom) lens with maximum aperture ranging between F3.5–5.1. The narrower aperture and zoom reach indicate limitations in low light and telephoto flexibility but reflect design tradeoffs favoring the waterproof housing.

Macro Capabilities

Both cameras allow macro focusing from 3 cm, enabling close-up shots suitable for flowers, insects, or textures. Olympus’s sensor-shift stabilization slightly aids macro sharpness, a notable advantage for detailed close-ups outside studio conditions.

Display and Viewfinder: User Interface and Image Review

Each camera sports a 2.7-inch fixed, non-touch LCD screen with 230k-dot resolution, providing a relatively low-res image review experience by today’s standards but typical for their release period.

The Olympus screen uses TFT technology, resulting in more vivid colors and better viewing angles outdoors compared to the Canon’s unspecified tech. However, neither model includes an electronic viewfinder, which may affect usability in bright sunlight.

Furthermore, screen size and resolution constraints somewhat limit the accuracy of manual focusing or composition checks, particularly critical for macro and professional work.

Burst Shooting and Video Capabilities

Burst Performance

Both cameras offer 1 fps continuous shooting, far behind modern standards but acceptable for casual use - sports or wildlife photographers will find this limiting for capturing decisive moments or fast action sequences.

Video Recording

Video capture tops out at 1280 x 720 pixels, 25 fps for Canon and 30 fps for Olympus, using H.264 compression. The TG-320 additionally supports smaller formats at 640 x 480 and 320 x 180. Audio input options are non-existent on both, preventing external mic usage - a notable limitation for serious videographers.

While neither supports 4K recording or advanced stabilization modes tailored for video, Olympus’s sensor-shift stabilization offers smoother handheld footage, a small but welcome advantage.

Weather Sealing and Build Quality: Durability for Field Use

Perhaps the starkest differentiation is the Olympus TG-320’s certified environmental resilience, including:

• Waterproofing (up to 3 meters)
• Shockproofing (can survive 1.5 m drops)
• Dustproofing
• Freezeproofing (operational to -10°C)

Such ruggedness renders it substantially more reliable in challenging outdoor or travel settings compared to the Canon A2400 IS, which lacks any form of weather sealing, implying users need to shield it carefully from adverse elements.
