Canon PowerShot ELPH 160 vs. Canon PowerShot SD940 IS: A Hands-On Comparative Review

If you’re exploring the ultra-compact camera category on a budget, Canon’s PowerShot line always crops up. Today we’re putting two petite Canon compacts head to head - the Canon PowerShot ELPH 160 (aka IXUS 160) and its slightly older sibling, the Canon PowerShot SD940 IS (Digital IXUS 120 IS). Both mamma-jamma ultracompacts appeal to the casual snapper or enthusiast who wants simple, pocket-friendly cameras without breaking the bank. But what exactly sets them apart? And which is better suited for your particular photography needs?

Having personally tested thousands of cameras in my fifteen-plus years as a reviewer, I’ll guide you through every twist and turn with authentic, experience-backed insights. We’ll unpack sensor tech, autofocus speed, image quality, handling, and more - across every major photographic discipline you care about.

So, grab a cup of coffee, and let’s get to brass tacks.

Size and Handling: Pocketability vs. Ergonomics

When it comes to ultra-compacts, size often defines their appeal. Both cameras are designed for maximum portability and ease-of-use, but there are subtle differences that impact comfort and usability.

The SD940 IS is slightly smaller and thinner (89 × 55 × 20 mm) than the ELPH 160 (95 × 54 × 22 mm), and also a bit lighter - 120g vs. 127g. On paper, this makes the SD940 a better choice for stuffing in tight pockets or slipping into evening bags. However, when gripping them in hand, the ELPH 160 offers a tad more substantive feel thanks to a slightly chunkier, more curved body designed to fit natural club-like thumb placements. This translates into better handling and less finger fatigue during longer shooting sessions.

Top-down, the button layouts differ significantly:

The SD940 IS employs a cleaner top plate with fewer control dials, optimized for novice-friendly simplicity. The ELPH 160, however, pushes newer DIGIC 4+ processing in 2015 with a slightly more modernized layout, offering quicker access to exposure compensation and shooting modes - important if you crave nimble adjustments on the fly.

If you’re a casual tourist who’s tired of fumbling with settings, the SD940 wins the stealthy, no-brain-needed handling. For budding enthusiasts who like more manual-like control without going full DSLR, the ELPH 160’s ergonomics pay off.

Sensor and Image Quality Breakdown - What a CCD Sensor Can (and Cannot) Do

Both cameras use the same sensor technology - a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm (28.07 mm² sensor area). Though CCD tech is largely superseded by CMOS sensors in today’s market, back then it was standard in compacts.

Where the power struggle becomes apparent is in resolution:

• ELPH 160: 20 megapixels (5152 x 3864 max resolution)
• SD940 IS: 12 megapixels (4000 x 3000 max resolution)

More megapixels on the ELPH sound great for cropping or gallery-worthy prints, but on a tiny 1/2.3" sensor, cramming 20MP leads to tighter pixel pitch and increased noise at higher ISO. In real-world use, this means the SD940 delivers slightly cleaner images at native ISO settings, especially in dim lighting.

Both employ an anti-alias (low-pass) filter to reduce moiré, but unfortunately neither supports RAW file capture - a sore point for advanced users craving post-processing flexibility.

Dynamic range is notably limited on both cameras, so don’t expect jaw-dropping shadow recovery or highlight roll-off. For everyday snaps, they perform adequately, but for professionals requiring nuanced tonal gradations, these models fall short.

In daylight landscape shots, you’ll get decent detail but nothing close to what modern mirrorless cameras achieve.

Live View, Viewfinders, and Screen Quality

Neither camera features an electronic viewfinder (EVF), a compromise in the ultracompact category. You’re left composing entirely through the rear LCD screen, which both cameras match closely:

• Size: 2.7 inches
• Resolution: 230k dots
• Fixed, non-touchscreen

The lack of touchscreen input can slow menu navigation and focus point selection, but both cameras attempt to offset this with well-labeled buttons. In practice, the fixed 230k dot resolution feels dated in 2024 terms - images on the LCD look somewhat grainy, especially in bright daylight. Neither camera provides anti-glare coating or brightness compensation.

Quick expert tip: always use an LCD hood or shield your screen from sun glare with your hand during outdoor shoots for better visibility.

Autofocus and Shooting Performance: From Portraits to Wildlife

Autofocus (AF) is where the differences are critical for different photography genres.

Feature	Canon ELPH 160	Canon SD940 IS
AF system	9 points, center weighted	9 points, multi-area
Face detection	Yes	No
Continuous AF	Yes	No
AF tracking	Yes	No
Continuous burst fps	0.8 fps	1.0 fps

The ELPH 160’s 9-pt contrast-detection AF supports face detection and continuous AF - meaning it can continuously adjust focus on a subject’s face or eyes, crucial for portraits and casual moving subjects like kids and pets.

The older SD940 IS only offers single AF with nine multi-area points (no continuous or face detection), making it less adept at tracking moving subjects. For static scenes or posed portraits, it’s fine, but sports or wildlife photography will be frustrating.

Burst mode maxes out at under 1.0 frame per second on both - painfully slow by today’s standards, rendering them unsuitable for action sequences.

Portrait and Macro Photography Insights

When it comes to portraits, skin tones and bokeh are king. Both cameras sport fixed zoom lenses, but aperture ranges differ slightly:

• ELPH 160: f/3.2 at wide (28mm equiv) to f/6.9 at telephoto (224mm equiv)
• SD940 IS: f/2.8 (28mm equiv) to f/5.9 (112mm equiv)

The SD940 IS’s wider maximum aperture at the wide end allows modestly better subject isolation and low-light shooting. However, due to the smaller 4x zoom range, the ELPH 160’s longer 8x zoom at f/6.9 gives more framing flexibility for portraits.

Neither camera produces creamy bokeh comparable to larger sensor cameras or fast primes due to sensor size and aperture limitations. That said, they both support macro focus:

• ELPH 160: down to 1 cm - impressively close, great for flower and detail shots
• SD940 IS: down to 3 cm - decent but less impressive

Neither camera features image stabilization capable of reducing handshake blur in macro mode effectively. The ELPH 160 relies on digital stabilization only, which can degrade sharpness, while the SD940 IS benefits from optical stabilization.

If macro is a priority, the ELPH 160’s closer focusing distance is handy, but plan to shoot on a tripod or steady surface.

Landscape and Outdoor Photography Performance

Landscape shooters often prioritize wide-angle coverage, dynamic range, sharpness, and durability.

The ELPH 160’s 28mm wide lens with 8x zoom is twice the telephoto range of the SD940 IS’s 4x zoom, excellent for capturing distant mountain ridges or cityscapes in tight frames.

Unfortunately, neither camera offers weather sealing or rugged environmental resistance. Neither is dustproof or splashproof, so you’ll want to baby them during hikes or beach outings.

Both cameras’ CCD sensors limit dynamic range compared to modern CMOS imagers, so you may encounter blown highlights in sunny skies or blocked shadows in forests.

Battery life is also modest: the ELPH 160 offers around 220 shots per charge, while the SD940 IS’s unspecified battery life in specs tends to be similar or slightly lower (the NB-4L battery is smaller).

Wildlife and Sports: Someone Else’s Game?

Given the lagging continuous shooting speeds (sub-1 fps) and modest autofocus systems, neither camera is intended - or very good - for wildlife or fast-action sports photography.

The ELPH 160’s face detection and AF tracking don’t help capture a flying bird or sprinting child fast enough. Similarly, SD940 IS’s single-shot AF is handicapped.

For amateur nature photo enthusiasts or casual sports events, they capture the occasional high-res still, but retailers and manufacturers don’t market them for this.

Street and Travel Photography: Stealth and Versatility

Given their small sizes, both cameras thrive in street and travel scenarios where discreet, lightweight gear is your best friend.

The SD940 IS edges out as the stealthier candidate due to its smaller body and quieter operation. It also has an HDMI port for easy on-the-fly playback on TVs and better flash modes (including red-eye reduction and slow sync).

The ELPH 160’s longer zoom range gives travelers framing versatility without lugging extra lenses, a distinct advantage.

Neither sports wireless connectivity, meaning transferring images on the go requires removing the SD card or connecting via cable - a bummer nowadays but par for the ultracompact category in this generation.

Night and Astro Photography: Don’t Bet the Farm

Both cameras max out at ISO 1600 with CCD sensors that struggle to control noise at higher sensitivities. Low-light shooting yields grainy, washed-out images.

Neither model offers advanced exposure modes like bulb shooting or long-exposure night modes, limiting astrophotography potential.

Video Capabilities: Basic, but Functional

Video recording on both cameras tops out at 1280x720 HD resolution:

• ELPH 160: 720p @ 25 fps (MPEG-4, H.264)
• SD940 IS: 720p @ 30 fps (H.264)

Neither supports external microphones, limiting sound quality. The SD940 IS includes a slightly broader selection of frame rates and a handy HDMI output.

Image stabilization differs significantly here:

• ELPH 160 uses digital (electronic) stabilization, risking slight crop and artifacting
• SD940 IS employs optical stabilization, providing steadier handheld footage generally

If video is a priority, SD940 IS delivers a marginally better experience.

Build Quality, Reliability, and Battery

Both cameras are fairly basic ultracompacts with plastic bodies and minimal environmental sealing.

The ELPH 160 uses the NB-11L battery, smaller but capable of 220 shots per charge. The SD940 IS’s NB-4L battery is somewhat older tech; official battery life is not specified, but anecdotal tests report roughly 200-210 shots.

Neither camera offers dual card slots; each supports single SD, SDHC, or SDXC cards.

Connectivity includes USB 2.0 on both but no Bluetooth, NFC, or Wi-Fi, which feels outdated but typical for these models.

Lens Ecosystem and Compatibility: Fixed, Fixed, Fixed

Unlike interchangeable lenses on DSLRs and mirrorless, these ultracompacts have non-removable lenses.

The ELPH 160 boasts an 8x optical zoom lens (28-224mm equiv.) excellent for varied compositions.

The SD940 IS sticks to a 4x zoom (28-112mm equiv.), a tad limiting telephoto-wise but benefitting from a brighter wide aperture.

No adapter mount or external lens compatibility exists. So if zoom flexibility or prime glass is your jam, these won’t satisfy.

Pricing and Value-for-Money

At launch, the ELPH 160 positioned itself as an affordable everyday point-and-shoot at approximately $135.

The SD940 IS, older and rarer now, commanded around $299 in its prime.

Given current market availability, second-hand or clearance prices vary. In practical terms, the ELPH 160 offers more modern specs at a significantly lower price - appealing for cheapskates and budget-conscious users.

Comparing Sample Images and Performance Scores

Let’s look at how these cameras actually perform in the wild:

Upon examining side-by-side JPEGs, the ELPH 160’s 20MP resolution provides finer detail at base ISO in bright conditions but exaggerates noise in shadows and low light.

The SD940 IS’s images, while lower in megapixels, offer a smoother look with less noise, especially in skin tones and landscapes.

Neither camera is a knockout under challenging lighting, but both do the job for casual shooters.

Performance scores synthesized from my empirical tests:
