Canon PowerShot SX160 IS vs Pentax Optio E90: A Detailed Comparative Review for Photography Enthusiasts

Choosing the right compact camera can be surprisingly challenging when you start stacking technical specifications against real-world use cases. Today, I’m diving deep into a head-to-head comparison of two long-ago-released but still interesting models for budget-minded photographers or collectors: the Canon PowerShot SX160 IS and the Pentax Optio E90.

Drawing on my experience testing cameras over the past 15 years - including numerous compact superzooms and point-and-shoots - I’ll analyze how these two fare across a broad spectrum of photographic disciplines and highlight their strengths and shortcomings.

Let’s unpack this step-by-step, always focusing on the practical realities of photography, not just specs on paper.

Getting to Know the Cameras: Design and Ergonomics

Initial impressions shape user enthusiasm, and ergonomics profoundly impact shooting comfort during long sessions.

The Canon SX160 IS sports a chunkier, superzoom style body typical of the early 2010s bridge cameras, built to offer a grip even for larger hands. At 111 x 73 x 44 mm and weighing in at 291g, it’s noticeably more substantial than the Pentax, which measures 102 x 59 x 25 mm and weighs a mere 145g.

This size difference translates to two distinct approaches: the Canon leans into a comfortable hold and physical dials, while the Pentax caters to ultra-portability and pocketability. Handling the SX160 IS feels sturdy, with controls accessible to the index finger and thumb, but the lack of a dedicated viewfinder means reliance on the fixed 3-inch LCD.

The Pentax E90’s compact and slender body favours quick grab-and-go usage - ideal for street and casual shooting. However, its minimal grip and smaller control buttons can detract from stable handling during longer shoots or when using zoom extensively.

From the top-down perspective, the Canon’s array of buttons and mode dial outnumbers the Pentax’s minimalist layout, offering more immediate control options.

For photographers who prefer manual tweaks at their fingertips, the Canon wins. The Pentax E90 feels simpler but less tactile, aimed at novices or casual users.

Sensor and Image Quality: Behind the Pixels

Both cameras use a 1/2.3-inch CCD sensor, a staple in compact cameras of their time, but there are crucial differences.

The Canon SX160 offers a 16MP resolution against the Pentax’s 10MP, naturally giving the Canon an edge in pixel count. But resolution is only the start of image quality discussions.

In my lab testing, I observed that while both sensors’ size is nearly identical, the Canon’s Digic 4 image processor manages noise reduction and color interpretation with slightly more sophistication. This manifests in cleaner images at base ISO and better color saturation, especially noticeable in skin tones and outdoor scenes.

Pentax’s Prime processor works well but tends to produce more muted colors and less dynamic range. Its maximum ISO 3200 sounds promising on paper, but practical use beyond ISO 400 introduces quite a bit of noise and detail loss, limiting low-light usability.

Neither camera supports RAW, restricting advanced post-processing, though the Canon allows custom white balance and exposure compensation, benefiting photographers who want finer control over image outputs.

Overall, the Canon’s sensor and processor pairing creates more versatile and vibrant images in daylight and moderate lighting.

LCD Screen and Viewfinder Experience

Neither camera has an optical or electronic viewfinder - a notable drawback for certain photography styles, such as outdoor bright sunlight shooting or sports.

The Canon features a 3.0-inch fixed TFT LCD screen with 230K dots, while the Pentax offers a 2.7-inch screen with the same 230K resolution.

The Canon’s larger display translates to easier framing and reviewing images, though the relatively low pixel density means the image preview isn’t crisply detailed. The screen’s fixed position limits compositional flexibility, but the screen technology is bright enough for outdoor use with some shade.

The Pentax’s smaller screen, also fixed, struggles more in bright conditions and makes manual focusing or fine detail assessments tricky.

Neither touchscreen nor tilting features are present on either camera, a reminder of their era. Live view autofocus is contrast-detection only on both, implying slower AF performance compared to modern phase-detect or hybrid autofocus.

Autofocus, Zoom, and Optics: Performance in the Field

The Canon SX160 IS boasts a superzoom lens covering an impressive 28-448mm equivalent focal length at 16x optical zoom. The maximum aperture ranges from f/3.5 to 5.9, typical for superzoom compacts, but giving flexibility from wide-angle landscapes to distant subjects.

In contrast, the Pentax E90 has a more modest zoom range of 32-95mm equivalent (3x zoom) with aperture from f/3.1 to 5.9, better suited for casual snapshots and portraits but limiting reach.

Thanks to its lens stabilization system, the Canon SX160 also provides optical image stabilization (OIS), helping to tame camera shake at long focal lengths or slower shutter speeds. The Pentax offers no stabilization, increasing the likelihood of blur without a tripod, especially zoomed-in.

Autofocus-wise, the Canon supports face detection and has multi-area AF points, albeit based on contrast detection (common in compact cameras of this era). Pentax relies on three AF points without face detection and notably no continuous AF tracking.

The Canon’s autofocus is generally faster and more reliable, an essential factor in shooting moving subjects, wildlife, or candid moments where time is fleeting.

Burst mode performance is limited on both, with the Canon capable of only about 1 frame per second continuous shooting - slow even by entry-level standards. Pentax doesn’t specify continuous mode speed, which usually indicates it’s not designed for action photography.

Real-world Photography Disciplines: How They Stack Up

Let’s translate the technical specs into uses across photography genres.

Portrait Photography

Skin tones and bokeh quality hinge on sensor performance and lens aperture. The Canon SX160, with higher resolution and face detection autofocus, handles portraits better, producing reasonably accurate flesh tones and modest background blur at the telephoto end.

The Pentax, with its shorter zoom and no face detection, feels less suited for flattering portraits. Its inability to focus closer than 6cm also limits close-up framing for headshots.

For hobbyist portraits under controlled lighting, Canon is preferable, but neither camera can replace a DSLR or mirrorless with prime lenses when serious bokeh and skin tone fidelity matter.

Landscape Photography

High resolution and dynamic range matter here. The Canon’s 16MP resolution serves detail better than Pentax’s 10MP. Both lack RAW, which means limited shadow recovery in post.

Long exposures and weather resistance influence landscape versatility. Unfortunately, neither camera includes any environmental sealing, so caution is necessary outdoors in inclement weather.

The Canon’s slower shutter speed range extends to 15 seconds vs. 4 seconds on the Pentax, aiding in low light or nightscape shots with a tripod.

Wildlife Photography

Wildlife demands fast autofocus and long reach. Canon’s 448mm equivalent superzoom unquestionably wins, both for framing distant animals and image stabilization.

Pentax’s 95mm equivalent lens leaves you wanting more reach, though the lighter body is easier to tote in hidden ambushes.

The Canon autofocus’s face detection and multi-area AF offer better subject acquisition, essential when shooting skittish wildlife.

Burst speed on both is lacking, precluding high-frame-rate capture of fast movements.

Sports Photography

Similar story here: Canon’s slower 1fps frame rate and contrast detection AF system limit capture of fast-paced action, making both cameras suboptimal for serious sports use.

Pentax falls short further with no burst mode or tracking AF.

Sports photographers would outgrow both quickly.

Street Photography

Pentax E90’s compact, lightweight frame and discreet outline make it more suited for street photography compared to the chunky Canon SX160.

Both suffer from no viewfinder and fixed LCD, which hinders composition in bright light, but the smaller size aids concealment.

Low light capabilities are comparable but limited - Pentax’s ISO 3200 is noisy, and Canon tops at ISO 1600.

Macro Photography

Canon offers a macro focus range down to 1 cm, which is impressive for a compact. Pentax starts at 6 cm, less ideal for extreme close-ups.

Manual focus on the Canon is supported, giving photographers more control over fine focusing in macro scenarios, while Pentax lacks manual focusing altogether.

Optical stabilization also supports steadier macro shots on the Canon.

Night and Astro Photography

Canon’s slower shutter speeds and ISO up to 1600 allow some low-light shooting but still constrained by sensor noise and lack of RAW.

Pentax’s ISO up to 3200 is theoretically better but so noisy that long exposure purity suffers.

Neither supports special astro modes or bulb exposures, so astrophotography is limited to very basic star trails or cityscapes on a tripod.

Video Capabilities

Both cameras max out at 720p HD resolution, but the Canon SX160 offers 30fps and 25fps at this resolution, while the Pentax records just 15fps at 720p - choppy compared to modern standards.

The Canon encodes with modern H.264, giving better compression and quality versus Pentax's Motion JPEG format, which eats storage rapidly.

Neither has microphone inputs or headphone jacks, ruling out serious audio recording.

Electronic image stabilization in video is absent on both, so handheld clips can get shaky at zoom or walking pace.

Travel Photography

Travel photogs seek versatility, battery life, and compactness.

The Pentax E90’s super-light, slim body is a joy for carry-on ease, but limited zoom can cramp framing options.

The Canon’s superzoom lens and image stabilization enable broad shooting styles from wide landscapes to distant landmarks, at the cost of larger size.

Battery life favors Canon slightly with 380 shots per charge using AA batteries commonly available worldwide. Pentax’s battery life isn’t broadly documented but likely similar given same battery type.

Professional Work

Both cameras are firmly consumer grade, lacking RAW capture, advanced exposure modes (Pentax lacks shutter/aperture priority), and rugged build.

For professional workflows requiring reliable color profiles, tethering, and robust weather sealing, neither fits well.

Build Quality, Weather Resistance, and Durability

Neither camera has weather sealing, dustproofing, shockproofing, or freezeproofing, so outdoor photographers must be cautious.

Canon’s larger, chunkier body feels more robust to daily wear, while Pentax’s slim shell is more vulnerable to accidental knocks.

No cameras have environmental certifications to safeguard against rain or dirt.

Storage, Connectivity, and Battery Life

Both cameras use SD/SDHC/SDXC memory cards, with a single card slot each.

Connectivity-wise, the Canon SX160 supports Eye-Fi wireless cards for Wi-Fi transfer, a handy feature for 2013-era devices. Pentax E90 has no wireless options.

Both utilize USB 2.0 for data transfer and charge/disconnect.

Battery-wise, both run on 2 x AA batteries, ideal for travelers due to ubiquity but adding weight compared with proprietary lithium cells.

Canon’s documented battery life is around 380 shots per battery set, a respectable number. Pentax doesn’t provide official figures, but expect similar endurance.

Price-to-Performance Ratio: Value Summary

As of original launch, the Canon SX160 IS retailed near $199, while the Pentax E90 was about $99, reflecting a significant budget difference.

For the price, Canon offers more substantial features: higher zoom capability, larger sensor resolution, image stabilization, and richer exposure modes.

Pentax’s cost benefits come with tradeoffs - lower resolution, no stabilization, limited zoom.

Sample Image Comparison: Visual Evidence

To ground this analysis, I compiled a gallery of sample images captured under identical lighting and shooting conditions with both cameras.
