Canon SD940 IS vs Sony DSC-W380: The Ultimate Ultracompact Showdown

Choosing the right compact camera is a bit like finding the perfect pocket knife - portable, versatile, dependable, and just the right blend of features. In this head-to-head, we're pitting two classic ultracompacts from the tail end of the 2000s against each other: Canon’s PowerShot SD940 IS (also known as the Digital IXUS 120 IS) and Sony’s Cyber-shot DSC-W380.

Both claim to deliver impressive images in tiny packages, but the devil's in the details. What makes one better suited for your travel escapades, or your next family portrait, or even your first timid foray into wildlife photography? I’ve spent ample time with both cameras, pushing them beyond the specs sheet, so buckle up for an experienced, candid look at which ultraportable might earn your cash.

Pocket-Sized Powerhouses: First Impressions and Ergonomics

Ultra-compact cameras are all about balance - cramming decent optics and sensors into a body you barely notice. Let’s start with their physicality.

Canon’s SD940 is trim and sleek, measuring 89 x 55 x 20mm and weighing 120 grams with battery - ideal for slipping into a jacket pocket. Sony is slightly longer but narrower (91 x 52 x 20 mm) and lighter at 117 grams, skimming the scales by 3 grams.

Handling these two feels distinctly different. The Canon’s curved, polished metal body offers a more premium sensation, while the Sony embraces a flat slab design with a glossy finish. Controls on both are minimalistic - befitting ultracompacts - but Canon’s buttons have a firmer, more tactile feel, something I appreciated when shooting outdoors with gloves.

Examining the top controls...

Canon’s layout keeps the power and shutter buttons nicely separated, reducing accidental shutdowns. Sony’s zoom toggle doubles as the shutter trigger, a design that feels a bit cramped, especially if you have larger hands. Neither camera offers manual dials, unsurprisingly, but both benefit from a clean, user-friendly button setup. For quick snaps and on-the-go shooting, Canon’s ergonomics slightly edge out Sony’s more minimalist approach.

Sensor Showdown: What’s Under the Hood?

A camera’s sensor is its beating heart, dictating image quality, dynamic range, and noise performance. Here, both cameras sport a 1/2.3-inch CCD sensor, measuring 6.17 x 4.55 mm - quite standard for ultra-compact cameras of their era.

But Sony’s W380 pushes ahead on resolution with 14 megapixels over Canon’s 12. It might look attractive on paper, promising slightly larger 4320 x 3240 pixel shots versus Canon’s 4000 x 3000. However, more megapixels crammed into a small sensor often lead to noisier images at higher ISOs, a critical consideration for low-light and night photography.

Both sensors include anti-aliasing filters, which reduce moiré patterns but soften fine detail marginally.

Real-World Image Quality: What You’ll Actually Get

Pixel count aside, the quality of photos boils down to the image processor and sensor efficiency. Canon’s Digic 4 processor is renowned for balanced color reproduction and clean images. Sony’s Bionz processor, running the W380, delivers punchy colors but can sometimes oversaturate - a style some might love, though purists might balk.

I conducted side-by-side tests indoors and in landscapes under varying lighting. Canon’s images tend to favor natural skin tones - great for portraits and family shots - with gentle, pleasing color rendition. Sony takes a punchier route, lending itself well to lively scenes if you don’t mind a splash of vibrancy.

Another noticeable difference: Canon’s maximum ISO tops out at 1600, while Sony can climb to ISO 3200 - we’ll revisit the implications for noisy images shortly.

The Lens Battle: Zoom, Clarity, and Versatility

Both cameras come with fixed zoom lenses, a standard for ultracompacts.

• Canon SD940 IS: 28-112mm equivalent (4x zoom), f/2.8-5.9
• Sony W380: 24-120mm equivalent (5x zoom), f/2.4-5.9

Sony’s edge in zoom and wider focal length at the short end makes it a more versatile travel companion, letting you squeeze in wider scenes or zoom in farther on subjects.

Optically, both lenses perform commendably in their class. However, Canon’s optics give slightly sharper results at the wider settings, particularly noticeable when shooting landscapes or architecture. Sony’s lens exhibits mild chromatic aberration (color fringing around high-contrast edges) during telephoto shots, but this is manageable.

When it comes to macro, Canon impresses with a focusing distance down to 3cm, versus Sony’s 5cm. In my tests, that translates into more intimate close-ups with Canon, perfect for budding macro enthusiasts.

Autofocus and Speed: Catching Moments in a Blink

Ultracompacts are rarely fast beasts, but autofocus (AF) performance can mean the difference between capturing or missing the shot.

Both sport a contrast-detect AF system with 9 focus points. Interestingly, Sony’s W380 offers “center-weighted” AF selection, giving you more control to pinpoint focus; Canon relies on a more generalized multi-area focusing.

I found Sony’s AF locks slightly faster in good light and holds focus reliably for static subjects, but struggles more in dimmer conditions, sometimes hunting persistently before settling. Canon’s AF is consistently reliable but slower overall, and it lacks face detection, which both cameras miss (a plus in some situations, and a drawback in others).

Continuous shooting speeds are limited - Sony maxes out at 2 fps, Canon at 1 fps - so high-action sports photography is off the table for either.

Composition and User Interface: How You See Your Shot Matters

Both cameras rely solely on their rear LCD for composition; no viewfinders here.

Each has a 2.7-inch fixed screen with a resolution of 230k dots - not flashy, but adequate. Sony’s interface is clean but can feel sluggish, especially when zoomed in live view. Canon’s live view is more responsive, likely benefiting from its Digic 4 processor, which improves both display smoothing and shutter lag.

I particularly appreciate Canon’s provision to set a custom white balance and easily access exposure adjustments, even if shooting modes are automatic or scene-based only. Sony is a bit more rigid with its defaults. Neither offers touchscreens, which is a notable omission for modern standard, but typical for their launch periods.

Video Capabilities: Casual Clips Made Easy

For ultracompacts, video is mostly a bonus, not a replacement for dedicated camcorders. Both cameras offer 720p HD recording at 30fps - Canon uses the efficient H.264 codec, while Sony records Motion JPEG files.

H.264 means significantly better compression, smaller file sizes, and fewer dropped frames, translating into smoother video with Canon. Sony’s Motion JPEG videos are larger, clunkier files, with noticeable compression artifacts.

Neither model supports external microphones or headphones, limiting audio quality options. Stabilization aids both slightly to reduce handheld shakiness.

Bottom line: if video quality matters, Canon’s approach is more modern and usable.

Battery Life and Storage: Are You Going to Run Out of Juice?

Both cameras use proprietary rechargeable lithium-ion batteries:

• Canon SD940 IS: NB-4L
• Sony W380: NP-BN1

Battery life figures aren’t widely documented, but real-world usage suggests both manage around 200-250 shots per charge under typical mixed-use. Neither will wow power users without backups.

Storage-wise, Canon supports SD, SDHC, MMC formats; Sony is slightly more versatile, also accepting Memory Stick Duo formats alongside SD/SDHC cards. That could be a tipping factor if you already own compatible cards.

Connectivity and Additional Features

Neither camera supports wireless (Wi-Fi, Bluetooth) or GPS, unsurprising for their time but worth noting if you hoped to skip cables.

Both cameras feature HDMI and USB 2.0 ports - adequate for transferring images or hooking up to TVs.

Canon shines with slightly more varied flash modes, including red-eye reduction and slow sync, whereas Sony offers basic auto, on, off, and slow syncro.

Who Wins at What? Photography Genre Performance

No ultracompact will replace a high-end DSLR or mirrorless camera for demanding pro work - but each can shine in specific roles.

• Portraits: Canon’s skin tone rendering and gentle bokeh help it shine here. Its f/2.8 wide aperture edges out Sony’s f/2.4-a bit, but the subtle color profile is a big plus. Neither has face detection, so composition discipline is key.

• Landscapes: Sony’s wider 24mm equivalent and 14MP resolution lend it a slight advantage for expansive vistas. But Canon’s edge in sharpness and contrast keeps images punchy.

• Wildlife: Both struggle due to limited zoom speed and autofocus tracking; for casual closer subjects, Sony's greater zoom range helps with framing.

• Sports: Slow burst rates and AF make both unsuitable, but Sony’s slightly faster 2fps is better if you must.

• Street Photography: Canon’s ergonomic grip and quieter operation earn it more points; Sony's flatter body is discreet but feels less confidence-inspiring.

• Macro: Canon’s better close-focus distance lets you explore this area more seriously.

• Night & Astro: Sony’s higher ISO ceiling (3200 vs 1600) exists mostly in theory; both show strong noise past ISO 400, so neither is great for astro without a tripod.

• Travel: Sony’s wider lens and lighter weight make it an appealing travel companion, but Canon’s more reliable autofocus and better processing make it a steadier shooter.

• Professional Workflows: Neither supports RAW files - a dealbreaker for pros. Both shoot JPEG only.

Final Thoughts: A Walk Down Ultracompact Memory Lane

Reflecting on these two cameras, I’m reminded how far compact cameras have come - yet how much these reliable performers still hold up for quick everyday shooting without fuss. They balance portability and decent image quality in ways smartphones of their day couldn’t match, often still outperforming today’s phone cameras in optical zoom and sensor control.

If your photography goals find you nodding along with their limitations and strengths, either Canon’s SD940 IS or Sony’s W380 can still carve out a happy niche, especially for casual shooters who occasionally want better quality than a phone.

But if you want a camera that keeps pace with today’s demands - autofocus tracking, RAW files, bigger sensors, 4K video - it’s time to graduate into mirrorless or advanced compacts like the Canon G series or Sony RX100 line.
