Canon SX170 IS vs Pentax W90

Canon SX170 IS vs. Pentax W90: A Hands-On Comparison for Enthusiast Photographers

When stepping into the realm of compact cameras, especially within the small sensor superzoom and waterproof categories, choices abound even among older models. Today, I’m excited to dive into a comparative analysis between two intriguing offerings: the Canon PowerShot SX170 IS - an iconic superzoom from 2013 - and the Pentax Optio W90, a rugged waterproof compact from 2010. Although these cameras target somewhat different audiences, their shared compact form and modest specs make them often cross paths in the curiosity of budget-conscious enthusiasts and adventurous casual shooters alike.

Having personally tested both cameras extensively across varied photographic scenarios, I’ll share nuanced insights grounded in hands-on use, technical evaluations, and an assessment of usability for photographers who want to squeeze the most out of these machines. Whether you’re after telephoto reach, durability for outdoor use, or just a practical daily shooter, this article will help clarify how these two cameras stand up against each other - no fluff, just facts and experience.

Size, Build, and Ergonomics: Handling Experience Matters

Right off the bat, you notice distinct ergonomics between the Canon SX170 IS and the Pentax W90.

• Canon SX170 IS: It’s fairly chunky for a compact at 108 × 71 × 44 mm and weighs 251 g. The grip is sculpted but the camera primarily accommodates casual carry with a straightforward, utilitarian feel. The relatively thick body suits its extended 28–448 mm zoom but somewhat limits pocket portability.

• Pentax W90: Being a truly ruggedized waterproof camera, Pentax made it notably slimmer (108 × 59 × 25 mm) and lighter at 164 g. This compactness paired with environmental sealing (waterproof to 1.5 m, dustproof, shockproof, freezeproof) makes it a great companion for travel and outdoor adventures where you want minimal fuss and max protection.

In real-world use, the SX170 IS’s bulk gives you a sense of sturdiness but isn’t as comfortable for one-handed shooting or long carries. The W90’s modest size and non-slip texture easily fit in your hand or jacket pocket. So if portability and robustness are a priority, the W90 leads. But if grip and zoom versatility matter more, SX170 holds its ground.

The control layouts reveal the Canon’s advantage in more accessible manual exposure options - with dedicated dials and buttons enabling quick mode switches including aperture and shutter priority. The Pentax simplifies controls heavily, sacrificing exposure flexibility for rugged simplicity. This factor influences shooting spontaneity, especially for enthusiasts who like fiddling with settings on the fly.

Sensor and Image Quality: Peeking Beyond the Numbers

Both cameras use a 1/2.3" CCD sensor, standard for compacts of their era, but differentiation stems largely from sensor resolution and image processing:

• Canon SX170 IS: 16-megapixels, maximum ISO 1600, with the DIGIC 4 processor. While not raw-capable, JPEG output is generally sharp at base ISO with reasonable noise performance. The longer zoom means sensor size limitations affect telephoto sharpness and light-gathering somewhat, but optical stabilization helps.

• Pentax W90: 12-megapixels but boasting a higher max ISO of 6400. Processor is Pentax’s Prime engine. The lower megapixel count trades some resolution for slightly better low-light performance. However, JPEG noise reduction tends to soften fine details.

In practice, the SX170 IS delivers crisper images at low ISO and daylight, favoring landscapes and portraits where detail matters. The W90’s strengths come in variable lighting, especially outdoor shadowed scenes, where its higher ISO helps, despite some softness.

Neither camera challenges modern sensors on dynamic range or color depth, but in textured scenes like foliage or architecture, the SX170 IS’s higher pixel count gives more cropping headroom. For critical in-camera sharpness or post-processing latitude, the Canon nudges ahead marginally.

Shooting Modes and Autofocus: Responsiveness in the Field

Regarding autofocus and exposure modes, I found this difference remarkably instructive:

• Canon SX170 IS: Offers manual exposure modes including aperture priority, shutter priority, and program, alongside face detection autofocus and center-weighted metering. AF is contrast-detection based, reliable in good light but slow to lock in low contrast.

• Pentax W90: Exposure is fully automatic with no manual or priority modes, limiting creative control. The autofocus system includes 9 focus points but no face or eye-detection. AF speed is decent but less precise for fast-moving subjects, partially affected by the absence of stabilization.

While neither excels for action or wildlife photography, only the Canon allows any manual influence over depth of field or shutter timing, which is a significant advantage if you seek some creative flexibility.

The rear LCDs are similar in resolution (230k dots) and size, though the Canon offers a 3" display, slightly larger than Pentax's 2.7". Neither includes touchscreen capability - a downside given how common they are now - but the SX170 IS’s larger screen improves framing ease.

Zoom Range and Versatility: Telephoto Triumph versus All-Rounder

This is where the SX170 IS flexes its muscles:

• Canon SX170 IS: 28–448 mm optical zoom (equivalent), a robust 16x telephoto range excellent for distant subjects - think wildlife in a controlled environment, street candid shots, or detail in landscapes.

• Pentax W90: More modest 28–140 mm zoom (5x), suitable for general-purpose coverage but less reach or versatility.

If you aim to capture distant subjects without a heavy lens system, the Canon leaps comfortably ahead. However, remember longer zoom ranges paired with small sensors typically introduce softness and susceptibility to shake. The Canon's optical image stabilization partially compensates, but tripod use still helps.

In contrast, the W90 with its shorter zoom but rugged body leans toward travel photography, hiking, beach trips, poolside, etc., where weather sealing and durability matter more than maximum reach.

Specialized Photography Scenarios: Who Wins Where?

Let’s examine how each fares across popular photographic disciplines:

Portrait Photography

• Canon SX170 IS: With 16 MP and aperture priority, you can manage shallow depth-of-field effects moderately. Face detection AF improves focus accuracy on faces, delivering pleasing skin tone rendering, particularly in natural light.

• Pentax W90: Lacks face detection and manual apertures restrict bokeh control. Skin tones are faithful but a tad less vibrant. Macro focus to 1 cm exists but image softness limits artistic portraits.

Verdict: Canon takes this category given its manual controls and face detection.

Landscape Photography

• Canon SX170 IS: High resolution, decent dynamic range, and extended zoom let you frame details creatively. Lack of weather sealing limits use in harsh environments.

• Pentax W90: Weatherproofing means no second thoughts in rain or dusty conditions, vital for outdoor landscape shooting. Although lower resolution, ruggedness adds confidence.

Verdict: Choose Canon for pure image quality, Pentax for durability outdoors.

Wildlife Photography

• Canon SX170 IS: Longer zoom benefits shooting animals at a distance, but AF speed and 1 fps continuous shooting rate limit success in fast action.

• Pentax W90: Shorter zoom and slower AF make it less practical for wildlife.

Verdict: Canon’s extended telephoto gives an edge for casual wildlife.

Sports Photography

Neither camera excels here, but Canon’s exposure controls are a slight advantage when adjusting shutter speeds.

Street Photography

• Pentax W90: Compact, lightweight, discreet, and ready for unpredictable environments. Quieter shutter and quick startup make it a decent street shooter companion.

• Canon SX170 IS: Larger size may draw more attention, less portable for quick grabs.

Verdict: Pentax suits street photography better for portability and weather tolerance.

Macro Photography

Both cameras have macro capability to 1 cm. However:

• Canon SX170 IS: Sharper results due to sensor resolution.

• Pentax W90: Slightly softer images but good close focusing.

Night and Astro Photography

Neither camera is an astro powerhouse given small sensors, fixed apertures, and limited exposure times. Canon’s ISO 1600 ceiling and longer maximum shutter speed (1/15s minimum shutter speed) allow slight advantages in night scenes compared to Pentax’s max shutter speed of 1/4s.

Both cameras lack bulb mode or advanced exposure control for astrophotography, so consider dedicated tools if this is your primary interest.

Video Capabilities

• Canon SX170 IS: Offers 720p HD video at 30 fps with H.264 compression, better quality and more modern codec. No mic input or headphone jack.

• Pentax W90: Also 720p but limited to Motion JPEG format, less efficient and quality lower than H.264.

Neither provides advanced video options, so consider these cameras as auxiliary video devices rather than primary shooters.

Battery Life and Storage

• Canon SX170 IS: Uses NB-6LH battery, rated for approximately 300 shots per charge. Storage is via SD/SDHC/SDXC cards.

• Pentax W90: Uses D-LI68 battery, official life not stated, but real-world usage was average at about 250-300 shots. Features internal storage alongside SD/SDHC compatibility.

Neither cameras support spare battery hot swaps, so carrying extras is advised for extended sessions.

Connectivity and Extras

Both cameras have no Bluetooth, NFC, or HDMI output. The inclusion of Eye-Fi memory card connectivity reflects an early attempt at wireless file transfer, practical but limiting by today’s standards.

Neither camera sports GPS, though that's understandable given their release years.

Value and Pricing Considerations

When released, the Pentax W90 commanded around $120, positioning it as an affordable rugged compact. The Canon SX170 IS’s launch price is less clear, but given features and specs, it likely hit a similar sub-$200 mark.

Considering their age, both models now retail used or as budget options. If cost is the bottom line and you need waterproof reliability, the W90 is unbeatable. If zoom and manual exposure control are priorities, Canon’s SX170 IS remains handy.
