Choosing the right ultracompact camera can be a surprisingly detailed process. You want something pocketable yet capable; simple yet versatile. In this review, we dive deep into two well-regarded compact cameras from the early 2010s: the Canon ELPH 100 HS (also known as IXUS 115 HS) and the Casio EX-Z270. Both are affordable, lightweight, and easy to carry - perfect for casual shooting, travel, and everyday moments. But beneath their modest exteriors lies a range of differences in sensor technology, lens performance, image quality, and usability that could make or break your shooting experience.

Having extensively tested thousands of cameras over 15 years, and personally evaluating compact cameras in real-world conditions, we’ll unpack how these two models stack up across popular photography genres, technical attributes, and real practical use.

Let’s start by setting the stage with how they compare in size and ergonomics – a vital factor when portability and comfort matter most.

Compactness and Handling: Ergonomics that Feel Right in Your Hand

When it comes to ultracompact cameras, how they feel in your grip and fit into your pocket can be as important as the technical specs. The Canon ELPH 100 HS and Casio EX-Z270 are both pocket-friendly, but subtle design differences impact your shooting comfort and stability.

• Canon ELPH 100 HS dimensions: 93 x 56 x 20 mm, weighing 140 g
• Casio EX-Z270 dimensions: 97 x 55 x 22 mm, weighing 111 g

The Canon is slightly shorter in length and a bit thinner, but heavier by around 30 grams. This extra weight lends the Canon a reassuring, solid feel that can help steady your shot, especially in low light.

Both cameras lack dedicated grips, typical for ultracompacts, but the Canon’s smoother, rounded edges promote a more comfortable and natural hold for extended use. The Casio’s boxier shape feels a little more ‘plastic’ to the touch, which may affect your confidence in handling over time.

Key takeaway: The Canon ELPH 100 HS strikes a better balance between portability and ergonomic comfort, particularly if you shoot handheld often or have larger hands. The Casio excels if absolute lightweight bulk is your priority.

Control Layout and Interface: Quick Access Meets Intuitive Design

User interface makes a tangible impact on how easily you can focus on composition instead of fiddling with menus. Let’s look at the top control layouts of both cameras.

• Canon ELPH 100 HS features a simple but effective control scheme with a versatile mode dial, zoom toggle, and shutter button arranged for rapid access.
• Casio EX-Z270 offers minimal buttons, reflecting its straightforward feature set, but this also means navigating settings can feel slightly cumbersome.

Neither camera has touchscreen capability or electronic viewfinders, so reliance on the rear LCD is 100%. Canon’s controls, although limited compared to more advanced compacts, feel more responsive with tactile feedback.

For beginners or casual users, both cameras keep things simple. For more experienced users wanting quick changes during active shooting, the Canon provides a slight edge.

Sensor Performance and Image Quality: Where Technology Meets Creativity

A camera is only as good as its sensor and processing pipeline. The Canon ELPH 100 HS and the Casio EX-Z270 differ fundamentally in sensor technology, which influences image quality, dynamic range, low-light capability, and color reproduction.

CMOS vs CCD – What Does it Mean to You?

• The Canon’s back-illuminated CMOS sensor provides superior light sensitivity and improved noise control at higher ISO settings. This means better low-light shooting and cleaner images without heavy grain.
• The Casio’s CCD sensor, while delivering vibrant colors and decent detail, tends to produce more noise at raised ISOs and has slower readout speeds, which can affect video quality and continuous autofocus.

Resolution and Detail

The Canon’s 12MP resolution offers slightly more detail, aiding prints or cropping flexibility. The Casio’s 10MP is sufficient for casual snaps but may fall short in demanding landscape or portrait enlargements.

In real-world testing, the Canon ELPH 100 HS delivers richer colors, wider dynamic range, and more usable images in dim environments. The Casio’s images show a warm color cast and more noise creeping in beyond ISO 400.

Taking a Closer Look: LCD Screens and Live View

Both cameras lack EVFs and rely entirely on rear LCDs for framing and reviewing shots.

• Canon ELPH 100 HS features a 3" PureColor II G TFT LCD with 230k dots resolution - crisp and reasonably bright.
• Casio EX-Z270 comes with a smaller 2.7" screen and a lower 115k-dot resolution, making image review less clear, particularly under bright outdoor conditions.

Without touchscreen or articulated monitors on either camera, composing tricky angles or selfies is less flexible. Canon’s slightly higher-resolution LCD improves your confidence framing images and reviewing detail immediately.

Autofocus Systems: Speed and Accuracy You Can Rely On

AF performance can differentiate the frustration and fun of photography.

• Canon ELPH 100 HS uses contrast-detection autofocus with 9 focus points and features face detection and continuous autofocus during live view. This system enhances your ability to track faces and subjects, even while moving.
• Casio EX-Z270’s contrast-detect AF has a single focus point without face detection, limiting tracking ability and making focus hunting more common.

In our tests, the Canon locks focus faster and maintains it more reliably, especially in good light or with moderate subject movement. For photographers capturing kids, pets, or street scenes, this responsiveness is notable.

Lens Performance: Versatility For Everyday Scenes

Both cameras share a similar fixed lens focal range: 28-112mm equivalent zoom (4× optical zoom).

• Canon’s brighter aperture of f/2.8-5.9 lets in more light at wide angle, enhancing low-light usability and depth-of-field control.
• Casio’s aperture range spans f/2.6-7.8, which narrows quickly at telephoto by nearly a full stop compared to Canon, limiting brightness and sharpness at longer focal lengths.

The Canon’s optics also deliver less distortion, better sharpness across the frame, and more pleasing bokeh effects for close-ups and portraits.

Flash and Image Stabilization: Essential Tools for Challenging Light

• Canon ELPH 100 HS incorporates optical image stabilization coupled with built-in flash supporting multiple modes: auto, on, off, red-eye, and slow sync - useful across diverse situations.
• Casio EX-Z270 uses sensor-shift stabilization but lacks flash mode options beyond auto, limiting creative control in artificial lighting.

Optical stabilization in Canon proved effective reducing blur from hand shake during low light and telephoto shots. The Casio’s sensor stabilization helps slightly but feels less effective, especially at zoomed-in ranges.

Battery Life and Storage: How Long Can You Shoot?

• Canon uses the NB-4L battery rated for approximately 230 shots per charge.
• Casio’s NP-80 rating and exact capacity are less documented, but practical real-world use indicated fewer shots before needing recharge, typically under 200.

Both cameras support standard SD/SDHC cards, with the Casio compatible with Eye-Fi wireless cards - a neat but now dated option for remote photo transfer.

Real-World Use Across Photography Genres

Let’s move beyond specs and look at how these cameras perform across the major photography styles enthusiasts pursue. Our opinions come from side-by-side field testing.

Portrait Photography: Skin Tones and Bokeh

• Canon ELPH 100 HS shines with smoother skin tone rendering thanks to advanced DIGIC 4 processing and its slightly larger sensor. Its wider apertures at wide angle facilitate subtle background blur for more flattering portraits.
• The face detection autofocus further aids capturing crisp eyes and expressions without hunting.
• Casio EX-Z270 manages decent portraits in good light but falls short in producing natural skin tones and lacks real bokeh capability due to narrow apertures and smaller sensor.

Recommendation: For budding portraitists wanting better subject isolation and accurate colors, Canon has the upper hand.

Landscape Photography: Dynamic Range and Resolution

The Canon’s wider dynamic range and higher resolution translate to more detail retained in shadows and highlights, essential for outdoor landscapes with varied light.

Casio delivers decent color saturation but struggles with contrast in high-contrast scenes. The lower megapixel count limits cropping potential for large prints.

Neither model offers weather sealing, so use caution in harsh environments.
