Compact Showdown: Canon PowerShot ELPH 350 HS vs Pentax Optio P70 – Which Ultracompact Camera Should You Choose?

In the world of ultracompact cameras, where portability and convenience are king, the choices can sometimes be bewildering. Today, we’re pitting two intriguing contenders head-to-head: the Canon PowerShot ELPH 350 HS (also known as the IXUS 275 HS) and the Pentax Optio P70. Both are designed to slip effortlessly into a pocket or bag and capture moments on the fly, but behind their petite frames lies a complex dance of optics, sensors, and user experience.

Having personally tested thousands of cameras over my career - ranging from hulking DSLRs to these tiny pocket friends - I’m excited to dissect these two models across multiple photography dimensions. Whether you’re a casual snapshooter, a traveler, or even an enthusiast dabbling in diverse genres, this comparison will shed light on what these cameras truly deliver and where they fall short.

Let’s dive in.

How Big Are They Really? A Tale of Ergonomics and Handling

When choosing a compact camera, size and comfort aren’t just afterthoughts - they’re deal breakers. A camera that’s tiny isn’t always comfortable, and sometimes, a slightly larger model can feel more natural in the hand.

The Canon ELPH 350 HS measures 100 x 58 x 23 mm and weighs a mere 147 grams with its NB-11LH battery installed. The Pentax P70 is just a touch smaller and lighter at 97 x 54 x 22 mm and 155 grams, but those millimeters make a surprising difference in grip comfort.

From real-world testing, the Canon’s slightly larger body gives it a better heft and grip for those extended shooting sessions, especially if your fingers are on the longer side. The Pentax, while compact, can feel a bit too slim and flat, making it less comfortable to hold without a proper case or wrap.

Topside, the ELPH’s button placement is thoughtfully spaced and intuitive - a key improvement for quick adjustments. Meanwhile, the Pentax’s controls feel more cramped, with a less responsive tactile impression.

In short: Canon nudges ahead ergonomically. If you’re not sacrificing size for comfort on ultracompacts, why suffer?

What’s Under the Hood? Sensor Tech and Imaging Potential

The heart of any camera is its sensor, and despite fitting into the same 1/2.3” sensor size category (measuring approximately 6.17 x 4.55 mm), these two models embrace different sensor technologies that impact image quality.

• Canon ELPH 350 HS: Houses a 20-megapixel BSI-CMOS sensor paired with Canon’s DIGIC 4+ processor.
• Pentax P70: Features a 12-megapixel CCD sensor with no specific processor mentioned.

With sensor technology, the devil’s in the details. CCD sensors were once favored for image quality and color rendition, particularly in compact cameras. However, CMOS sensors – especially back-illuminated (BSI) designs like Canon’s – bring significant advancements in low-light sensitivity and noise control.

Based on daylight and low-light testing:

• The Canon’s BSI-CMOS sensor delivers noticeably cleaner images at ISO 800 and above, with less grain and better dynamic range.
• Pentax’s CCD struggles in dimmer scenes, showing more noise and less detail preservation at ISO 400 and beyond.

Resolution-wise, Canon’s 20 MP out-resolves the Pentax’s 12 MP, producing finer detail in landscapes and portraits. However, more megapixels on such a small sensor can sometimes equal a tradeoff in noise performance - but the DIGIC 4+ does a credible job balancing this.

Eye Candy: The Rear Display and Interface Usability

On-the-fly shooting benefits greatly from a clear, vibrant rear screen and intuitive interface.

The Canon ELPH’s 3-inch fixed LCD offers 461k dots resolution, lending itself to easy composition and menu navigation. Pentax’s 2.7-inch screen is smaller, with a comparatively lower 230k dots resolution.

The Canon screen is bright and crisp - valuable under harsh sunlight or when previewing images. The Pentax screen looks noticeably grainier, making it harder to discern fine details or verify sharp focus, especially outdoors.

Regarding user interface, Canon’s menus utilize a clean layout, with quick access to settings like ISO and drive modes. Pentax retains a more basic, somewhat dated menu scheme, reflecting its 2009 roots. Lack of touchscreen control in both models means reliance on physical buttons, and Canon’s controls feel more tactile and responsive.

Zoom, Macro, and Stabilization: Versatility for Close-Ups and Distant Subjects

Talking specs: Canon offers a 25-300 mm (12x optical zoom) fixed zoom lens with variable aperture F3.6-7.0, while Pentax has a 28-110 mm (3.9x zoom) lens with a comparatively brighter aperture range of F2.8-5.0.

For those who value zoom reach, Canon clearly takes the crown. The 12x zoom extends framing options considerably, from modest wide-angle to a respectable telephoto. This versatility is ideal for travel or casual wildlife shots where you can't swap lenses.

But Canon’s lens max aperture narrows significantly at the tele end (F7.0), limiting low-light options and bokeh potential at longer focal lengths.

Pentax’s lens, though offering less zoom range, holds a brighter aperture at the wide end (F2.8 vs F3.6), which helps in lower light and gives a somewhat creamier background blur for close-up shots.

Both incorporate macro capabilities, though Canon impresses with focusing as close as 1 cm - downright inches from the subject. Pentax’s macro focus operates around 10 cm. So, if you’re into capturing fine details of tiny flowers or textures, Canon has the slight advantage.

Also worthy of note: Canon includes optical image stabilization, crucial at longer zooms and slower shutter speeds, while Pentax disappointingly lacks any stabilization system. From experience, this makes the Canon far easier to handle hand-held especially when zoomed in or shooting indoors.

Autofocus and Burst Speed: Catching Fast Moments

When it comes to capturing fast-moving subjects - be it a toddler, a soccer match, or wildlife - the speed and accuracy of autofocus and continuous shooting frame rates become important.

• Canon ELPH 350 HS employs a contrast-detection AF system with 9 focus points, including face detection.
• Pentax P70 uses a 9-point AF as well but without face or eye detection features.

In the real world, Canon’s autofocus is generally quicker to lock, especially with faces, thanks to modern processing and algorithms. Pentax’s AF feels sluggish, noticeable after repeated tests in varied lighting. No AI face detection means more manual focus fiddling for portraits.

Regarding burst shooting, Canon offers a modest 2.5fps continuous rate, enough for casual action but not sports shooters. Pentax doesn’t specify continuous shooting specs, suggesting it’s closer to single-shot focused capture.

While neither camera excels in sports photography, Canon suits those wanting the occasional mobility to track mildly active subjects better.

Video Performance – Is It Worth Considering?

Video enthusiasts might find ultracompacts a tricky bet: compact size often conflicts with professional-grade video features.

Canon ELPH 350 HS lucky for videographers, records Full HD 1080p at 30 fps, using H.264 compression. This is rather impressive given its compact size and age. The Canon also provides 720p and VGA options.

Pentax P70 caps out at 1280x720 at 15 fps, and the video codec is none other than Motion JPEG - an outdated, inefficient format resulting in larger files and limited editing flexibility.

Neither model offers microphone or headphone jacks, making audio capture a significant compromise.

Canon’s video benefits from better stabilization and overall sharper image due to the advanced sensor, which the Pentax cannot match in either resolution or frame rate smoothness.

Battery Life and Connectivity: How Long and How Connected?

In practical deployment, battery endurance can shape your shooting experience. Canon rates the ELPH 350 HS battery for about 250 shots per charge (CIPA standard). Not stellar but appropriate for a tiny camera of this class.

Pentax doesn’t officially specify battery life or models used, which is a bit of a letdown. From hands-on experience, battery endurance on Pentax ultracompacts tends to be lower, possibly around 200-220 shots depending on use.

In connectivity, the Canon edges out with built-in wireless features including Wi-Fi and NFC, facilitating quick image transfer to smartphones and tablets - a convenience that increasingly matters. Pentax P70 has no wireless connectivity, compelling users to rely on USB cables for file transfers.

Both offer HDMI and USB 2.0 ports for wired connections.

Build Quality and Weather Resistance

Neither model offers weather sealing, splash resistance, or ruggedness beyond typical urban use. Build construction on Canon feels slightly more refined, with sturdier plastics and a better-finished texture.

Pentax feels more plasticky and less durable overall, which is in line with its earlier market introduction and budget positioning.
