Canon PowerShot S90 vs Canon SX220 HS: An Expert Comparison for Discerning Photographers

When evaluating compact digital cameras, particularly those balancing advanced features against portability, it's crucial to move beyond marketing claims and focus on real-world, technical distinctions that impact photographic results and user workflows. In this in-depth comparison, I dissect the Canon PowerShot S90 and the Canon SX220 HS - two similarly dated but distinctly purposed Canon compacts - to provide an exhaustive performance, usability, and value assessment. Drawing upon extensive hands-on testing protocols spanning over 15 years, this guide equips photography enthusiasts and professionals to select the camera best aligned with their specialized shooting requirements.

A Tale of Two Canon Compacts: Positioning and Design Intent

At launch, the Canon PowerShot S90 (2010) targeted discerning users craving premium image quality and manual control in a pocket-friendly form. Contrarily, the Canon SX220 HS (2011) was designed as a superzoom budget-friendly alternative, emphasizing versatility through an extended zoom range while sacrificing certain image quality parameters typical of high-end compacts.

Build, Ergonomics, and Control Layout

Both cameras share compactness but diverge subtly in their physical footprints, with the SX220 HS measuring slightly larger to accommodate its extensive zoom lens.

The S90's build prioritizes grip comfort and manual control. Despite its compact size, it incorporates an advanced set of physical dials and buttons enabling quick aperture, shutter speed, and exposure compensation adjustments without menu hunting - imperative for professional workflows where speed and tactile feedback matter.

In contrast, the SX220 HS opts for a simplified button scheme befitting casual users prioritizing zoom versatility over manual manual interface complexity.

The S90's control architecture reflects its advanced imaging ambitions, while the SX220 HS emphasizes straightforward operation.

Sensor Technology and Imaging Performance: CCD vs BSI-CMOS

Sensor Specifications and Physical Size

A significant foundational difference lies in sensor technology and size. The S90 employs a 1/1.7" CCD sensor measuring 7.44 x 5.58 mm, yielding an effective area of 41.52 mm² and 10 megapixels resolution (3648 x 2736 pixels). Meanwhile, the SX220 HS integrates a smaller 1/2.3" BSI-CMOS sensor sized at 6.17 x 4.55 mm (28.07 mm²) with 12 megapixels (4000 x 3000 pixels).

Implications for Image Quality and Noise Performance

The larger sensor area of the S90 grants superior light gathering capacity, directly reducing noise and enhancing dynamic range. The CCD sensor's superb color depth (20.2 bits per DxOmark tests) and dynamic range around 11 EV offer more latitude in post-processing and better highlight retention - a critical factor for landscape and portrait work.

By contrast, the SX220 HS's smaller CMOS sensor - a back-illuminated design optimized for improved light sensitivity - performs well for a model of its category but exhibits inherently higher noise levels at comparable ISO settings and reduced dynamic range. Its 12-megapixel resolution translates to slightly finer detail potential but can aggravate noise in low illumination.

Maximum Native ISO and Low-Light Usability

Both cameras cap maximum ISO at 3200, but real-world tests reveal the S90 producing cleaner output up to ISO 800, with usable results at ISO 1600. The SX220 HS, while capable of ISO 3200, introduces more luminance and chroma noise, limiting its low-light efficacy for critical applications.

Lens Quality and Zoom Range: Fixed Focal and Versatility Tradeoffs

Focal Length and Aperture Comparison

• S90: 28–105 mm equivalent (3.8× zoom), f/2.0 (wide) to f/4.9 (tele)
• SX220 HS: 28–392 mm equivalent (14× zoom), f/3.1 (wide) to f/5.9 (tele)

The S90's fast maximum aperture of f/2.0 at the wide end facilitates superior low-light performance and creates shallower depth of field, beneficial for portraits and selective focus macro shots. Additionally, the lens exhibits high optical quality with low distortion and chromatic aberration.

SX220 HS trades aperture speed for substantial reach, ideal for travel and wildlife scenarios demanding longer lens reach without swapping gear. However, the narrower apertures hamper performance in dimmer environments and limit bokeh capabilities.

Macro Performance

Both models deliver a close focusing distance of 5 cm, suitable for casual macro photography, with the S90's faster lens aperture complementing fine detail capture.

Autofocus Systems and Speed

AF Technology

S90 uses contrast-detection autofocus with 9 selectable points, including multi-area and center-weighted modes but lacks face detection and continuous AF tracking. SX220 HS advances with the same 9-point array but adds face detection and continuous autofocus tracking, improving performance for moving subjects and casual portraiture.

AF Speed and Accuracy

In practice, the SX220 HS's AF, supported by DIGIC 4 with iSAPS technology, acquires focus faster - particularly evident when re-composing or tracking moving targets, making it better suited for dynamic shooting such as sports or wildlife.

The S90, prioritizing imaging precision over speed, delivers reliable focus for static subjects but may lag behind in burst or rapid action scenarios.

Shooting Modes, Continuous Shooting, and Burst Rates

• S90 Continuous Shooting: 1 frame per second (fps)
• SX220 HS Continuous Shooting: 3 fps

The SX220 HS's superior burst rate aligns with its sports and wildlife aspirations, allowing brief sequences of motion capture. The S90’s slower continuous shooting limits action photography possibilities.

Each camera offers manual exposure, aperture priority, and shutter priority modes, but the S90’s manual exposure control is more refined, appealing to experienced users.

Image Stabilization and Shutter Speeds

Both cameras employ optical image stabilization (OIS) aiding handheld shooting clarity, with the SX220 HS’s dual-layer stabilization accommodating its extended zoom range more critically.

S90’s shutter speed range spans 15 sec to 1/1600 sec, while SX220 HS extends further up to 1/3200 sec, opening broader creative options for daylight shooting and fast action.

Viewfinder and LCD Interface

Neither camera includes a viewfinder.

LCD Screen and Interface

Both feature fixed 3-inch LCDs at 461k-dot resolution, but SX220 HS enhances viewing with PureColor II TG TFT technology, yielding sharper and more color-accurate previews under various lighting.

User interface on the S90 is more customizable and professional-oriented, with quick access to essential camera functions, whereas the SX220 HS leans toward simplicity.

Video Recording Capabilities

SX220 HS significantly outshines the S90 in video:

• SX220 HS supports Full HD 1920 x 1080 at 24 fps, alongside 720p and slow-motion modes (up to 120 fps at VGA).
• S90 maxes out at 640 x 480 VGA at 30 fps.

Both use H.264 compression but lack external microphone inputs, limiting audio quality enhancements.

For multimedia enthusiasts combining stills and video, the SX220 HS presents a clear advantage.

Battery Life and Storage

• SX220 HS rated for approximately 210 shots per charge using NB-5L battery.
• S90 uses NB-6L battery with no official CIPA rating, though real-life use suggests marginally fewer captures.

Both rely on SD/SDHC card formats, but SX220 HS extends support to SDXC.

Connectivity and Additional Features

Neither camera offers wireless capabilities (Wi-Fi, Bluetooth, NFC), aligning with era expectations.

Both offer HDMI output; USB 2.0 for tethering and data transfer.

Environmental sealing is absent from both, restricting outdoor shooting under adverse weather conditions.
