The Lay of the Land: Physical Design and Build Quality

At first glance, the SX160 IS and SX170 IS appear near-identical: both feature a compact “point-and-shoot” style with fixed 28-448 mm (equivalent) 16x zoom lenses and a similarly sized 3-inch 230k-dot TFT LCD. However, a closer look at the dimensions and weight highlights some subtle ergonomic evolutions:

• Canon SX160 IS: Measures 111 x 73 x 44 mm; weighs approximately 291 g (with batteries). Uses two AA batteries.
• Canon SX170 IS: Slightly smaller at 108 x 71 x 44 mm; lighter at around 251 g. Powered by a proprietary NB-6LH rechargeable lithium-ion battery.

While the size difference may appear marginal, the shift from AA batteries in the SX160 IS to a rechargeable lithium-ion battery pack in the SX170 IS significantly improves user convenience and reduces ongoing operating costs - not to mention the impact on camera weight and balance during extended handheld use.

Both models lack any substantial weather sealing, dustproofing, or shock resistance, typical of entry-level designs prioritizing affordability and portability over ruggedness. The plastic body construction feels reasonably robust but does not inspire confidence for harsh outdoor or adventurous shooting conditions.

Top Controls and Interface Layout

Examining the top controls, both cameras employ similar layouts with zoom rocker, shutter release, and mode dial clearly positioned for straightforward one-handed operation. The SX170 IS employs minor tweaks in button feedback and feel, enhancing tactile precision subtly. However, neither camera features a touchscreen or an electronic viewfinder - a notable omission that impacts usability in bright environments and limits manual framing control.

Under the Hood: Sensor and Image Quality Analysis

At the heart of any camera lies its sensor and image processing engine. Both PowerShot models use Canon’s aging CCD 1/2.3-inch sensor with 16 megapixels (approx. 4608 x 3456 resolution) and a native ISO range of 100 to 1600. The sensor size measures approximately 6.17 x 4.55 mm, delivering a modest imaging surface of 28.07 mm².

CCD Sensor and Image Processing Details

The CCD sensor architecture emphasizes color accuracy and detail retrieval at base ISO but suffers from increased noise and limited dynamic range at higher ISO sensitivities. Both cameras employ Canon’s DIGIC 4 image processor, which was state-of-the-art several years ago but comparatively slower and less capable than recent generation engines in noise management and processing speed.

Our tests, including Imatest benchmarks and controlled shooting across multiple ISO levels, reveal very similar image quality between the SX160 IS and SX170 IS, with no significant improvements in sensor performance or signal-to-noise ratio between the two. This uniformity results from their shared sensor and processor architecture.

Lens Optical Characteristics

The fixed zoom lens on both models covers a versatile focal length from 28mm wide-angle to 448mm telephoto (16x zoom), facilitating general-purpose shooting from landscapes to distant subjects. The maximum aperture varies from f/3.5 at the wide end to f/5.9 at full telephoto, typical for compact lenses at this zoom range.

Macro capabilities extend to 1 cm focusing, a notable strength for close-up shots, although edge softness and chromatic aberrations increase noticeably at close and long focal lengths. Optical image stabilization (OIS) is present in both, crucial for handheld telephoto sharpness, especially given relatively slow maximum apertures.

User Interface and Viewing Experience

Neither camera offers a touchscreen interface or electronic viewfinder (EVF), which constrains usability in bright sunlight and complicates manual composition techniques. Both rely exclusively on the 3-inch LCD screen of modest 230k resolution, adequate for framing in shaded environments but potentially frustrating in direct sunlight.

Exposure settings support manual modes including shutter priority, aperture priority, and full manual exposure, rare for compact cameras at this price point. Both provide identical autofocus capabilities via contrast detection, face detection, and center-weighted metering, but lack advanced multi-point AF systems or continuous autofocus tracking optimized for moving subjects.

The SX170 IS offers a slightly refined menu system, improving legibility and navigation speed, but the overall interface and control scheme remain fundamentally the same as its predecessor.

Autofocus and Shooting Speed Verdict

Both cameras feature approximate single-shot autofocus centering on a single high-contrast detection area with face detection assisting where possible. Continuous autofocus and tracking are minimal, insufficient for capturing fast-moving subjects reliably. The maximum continuous shooting speed is a mere 1 frame per second on both models - a painfully slow rate for sports or wildlife photography that demands rapid burst capture.

The shutter speed range spans from 15 seconds to 1/3200 seconds, enabling basic long-exposure night photography and daylight action shots, though the absence of electronic shutter limits silent shooting.

Video Capabilities: Modest 720p HD Performance

Neither camera offers 1080p Full HD video recording; both capture video at up to 1280 x 720 pixels at 30 frames per second using H.264 compression. The SX170 IS adds MPEG-4 format support, potentially offering better compatibility with some editing software.

Microphone and headphone ports are absent, limiting audio input options and monitoring - the consequence of prioritizing compactness and simplicity here. The lack of image stabilization modes optimized for video leads to shaky footage during handheld recording, particularly at telephoto zoom.

Therefore, these cameras serve best as casual video recorders rather than professional video tools.

Battery Life and Storage Considerations

One clear distinction emerges in battery systems:

• Canon SX160 IS utilizes two AA batteries (alkaline or NiMH rechargeable), facilitating easy replacement in the field without dependence on charger availability, a definite advantage for travel photographers in remote locations. However, AA power supplies increase weight and bulk slightly and often cost more per shot compared to proprietary lithium-ion.

• Canon SX170 IS shifts to NB-6LH lithium-ion rechargeable batteries, reducing weight significantly and offering about 300 shots per charge, though requiring recharging infrastructure.

Memory storage utilizes SD/SDHC/SDXC cards in a single card slot for both, providing ample compatibility and flexibility.

Assessing Special Features: Connectivity and Extras

Both models have Eye-Fi wireless card compatibility enabling limited Wi-Fi transfer, but neither offers built-in Wi-Fi standard, Bluetooth, NFC, GPS, or HDMI output. USB 2.0 connectivity is present but limited to image transfer and basic tethered control, with no external accessory ports such as microphone or flash hotshoe.

Built-in flashes provide basic illumination with similar 3-meter range and multiple flash modes including Auto, Off, Red-Eye Reduction (SX160 IS), and Slow Sync. The external flash is unsupported on both models, limiting options for advanced lighting.

Photography Discipline Performance Breakdown

Portrait Photography

Both cameras’ built-in face detection autofocus systems assist in tighter portrait focusing, but limited autofocus speed and a modest number of focus points reduce responsiveness. The 28mm wide angle and moderate telephoto range support natural to compressed perspectives, while aperture range controls background blur to some extent.

However, 16-megapixel 1/2.3-inch sensors inherently struggle to achieve smooth bokeh and shallow depth of field typical of DSLR or mirrorless cameras with larger sensors and faster lenses. Skin tone rendition is accurate at base ISO owing to CCD color characteristics but degrades at higher sensitivities.

Landscape Photography

Image resolution provides sufficient detail for web and small to medium prints but falls short of the clarity and dynamic range critical for professional landscape photographers.

The lack of weather sealing discourages use in harsh outdoor conditions, and the lens's maximum aperture of f/3.5 is moderate for creative depth control in landscapes, though optical stabilization assists in handheld shooting. Thin dynamic range under bright contrast conditions means highlights can clip and shadow details get lost, requiring careful exposure or bracketing.

Wildlife Photography

The superzoom lens extends reach to 448mm equivalent, useful for distant wildlife capturing, but autofocus performance and sluggish continuous shooting rate hamper fast subject acquisition and action freezing.

Additionally, contrast-detection AF combined with single frame rate of 1 fps is insufficient for tracking unpredictable movement. Both cameras fall short in this demanding domain.

Sports Photography

Similarly, slow autofocus and low burst rates preclude effective sports capture, where rapid frame rates and focus tracking are vital. The cameras lack phasedetect AF and high-speed continuous shooting modes present in more advanced models.

Street Photography

Both cameras’ compact size, moderate weight, and discreet appearance facilitate street photography, but lack of a viewfinder and relatively conspicuous lens barrel may affect certain candid shooting styles. The fixed screen can pose challenges in bright daylight compositions.

Low light performance is limited by sensor noise beyond ISO 400-800, making night street photography suboptimal. Still, the intuitive control layout and exposure modes suit casual shooters.

Macro Photography

Close focusing to 1 cm allows interesting macro exploration of small subjects, complemented by effective optical stabilization. However, fixed lens quality may induce edge softness and chromatic aberrations, and lack of focus stacking limits depth-of-field control.

Night and Astrophotography

Long exposure capability to 15 seconds enables star trails and night scenes, but sensor noise and low dynamic range restrict image clarity and color depth at high ISO or prolonged exposures. Without RAW format support, post-processing latitude is constrained.

Video Usage

720p video recording suffices for casual clips but disappoints for users prioritizing high-definition footage or external audio. The absence of microphone input, 1080p recording, and advanced stabilization limits utility for serious video shooters.

Travel Photography

The SX170 IS’s smaller size, lighter weight, and rechargeable battery pack render it a friendlier travel companion. Both cameras’ extensive zoom lens covers many travel scenarios well, but lacking weather sealing and viewfinders reduce versatility.

Professional Usage

Both models primarily target consumer-level users. Lack of RAW support severely limits professional workflow integration, while modest sensor and autofocus systems make them unsuitable as primary tools for demanding photographic assignments.
