Getting to Know the Players: Compact Cameras in Context

Before diving into specs and features, it's helpful to understand where these cameras sit in the compact spectrum:

• Canon PowerShot A490: An entry-level compact designed for straightforward casual use. It represents the early 2010 era of point-and-shoots with simplified controls and modest imaging capabilities.

• Sony Cyber-shot DSC-WX70: A more modern compact offering from 2012 with enhanced image processing, better sensor tech, and improved video specs, aimed at users wanting higher performance in a pocketable form.

Both cameras feature fixed lenses with small 1/2.3-inch sensors, so we're focusing on real-world usability, image quality within sensor limitations, and how their systems support various photography types.

Physical Feel and Handling: Size, Ergonomics, and Controls

Handling comfort and intuitive design become surprisingly important with compacts, as your connection to the camera impacts creativity and shooting pleasure.

The Canon A490 takes a slightly chunkier, heavier approach - primarily due to AA batteries. For many, this can provide the reassurance of easy battery swaps anywhere, though the size and weight might feel clunky if you prefer ultra-lightgear.

The Sony WX70 impresses with slimming down to less than 115g, making it easier to pocket and carry leisurely. The inclusion of a touchscreen adds intuitive control, speeding up menu navigation and AF point selection. In contrast, the Canon’s button-based interface feels dated and less flexible.

Both lack viewfinders, nudging you to rely on their LCD screens. However, the Sony’s higher-resolution 3-inch display yields a more detailed, vibrant live view. Check out the control layouts from the top view to see button placement differences:

Ergonomically, the WX70’s slim body means you’ll want to ensure a good grip with your hands, whereas the Canon’s bulk might feel steadier but less sleek for travel.

Sensor and Image Quality: Foundation for Great Photos

The heart of any camera is its sensor, dictating resolution, noise performance, and dynamic range.

Though they share identical sensor physical dimensions, the Sony WX70 leverages a more modern backside-illuminated CMOS sensor and the BIONZ processor. This combination enhances light gathering, allows higher resolution, and improves high ISO noise handling - even if the 1/2.3” sensor size limits low-light performance compared to larger sensor cameras.

In contrast, the Canon A490’s older CCD sensor caps at 10MP and struggles beyond ISO 400, exhibiting noticeable noise and less dynamic range. Its anti-aliasing filter helps smooth moiré but also slightly softens images.

For prints or casual sharing, the WX70's increased resolution will benefit landscape or travel shots, providing more detail and cropping flexibility.

Autofocus and Shooting Speed: Capturing the Decisive Moment

Fast, accurate AF and reliable burst rates are essential for sports, wildlife, street, and macro photography.

Sony’s WX70 autofocus system is markedly superior. It boasts face detection and AF tracking, ideal for portraits and casual wildlife or street shooting to maintain focus on moving subjects. The Canon’s fixed 5-point AF lacks these smart features, making manual timing essential.

Burst shooting at 10 frames per second on the WX70 offers great potential for capturing quick action in sports or wildlife, while the A490’s 1 fps burst rate restricts capturing movement effectively.

Lens and Zoom Capabilities: Versatility for Every Scene

Fixed lenses on compacts limit flexibility but vary in focal length and aperture speed:

The WX70 covers a wider focal range (25-125mm) with a longer zoom and slightly faster wide aperture of f/2.6 vs. f/3.0 on the Canon. This gives it an edge for low-light shots and capturing wider scenes. The Canon’s macro focusing as close as 1cm is impressive in theory but limited by sensor and processing.

Screen, Viewfinder, and User Interface

Without electronic viewfinders on either model, you rely on the LCDs:

The Sony WX70’s large, high-res touchscreen significantly boosts usability, allowing intuitive AF point selection and menu navigation. The Canon’s small, low-res screen feels cramped, making critical focus and exposure checking more difficult.

Video Capabilities: From Memories to Content Creation

Video has become an indispensable feature in compact cameras.

The Sony WX70 is a clear winner for videographers. Full HD at 60fps produces smooth, sharp video, enhanced further by optical image stabilization. The Canon is limited to VGA resolution and lacks stabilization, making it impractical for serious video projects.

Battery Life and Storage

Practicalities of battery and storage bear on long shooting sessions and travel.

While the Canon uses ubiquitous AA batteries, convenient when traveling without access to chargers, you’ll spend more long-term on replacements. The Sony’s rechargeable battery offers consistent performance but requires charging infrastructure.

Durability and Build Quality

Neither camera claims environmental sealing or ruggedness. Both are compact lifestyle devices best suited to light casual use rather than the rigors of professional fieldwork.
