Canon ELPH 100 HS vs Sony Cyber-shot DSC-T90: An In-Depth Comparison for Photography Enthusiasts

Choosing the right ultracompact camera often feels like walking a tightrope between portability, image quality, and feature set – especially when the options are from such reputable brands as Canon and Sony. Having personally tested both the Canon ELPH 100 HS and the Sony Cyber-shot DSC-T90 over various shoots spanning landscape vistas to street scenarios, I’m excited to share a hands-on, detailed comparison that goes beyond specs to real-world photography outcomes.

Let me take you through their nuances, strengths, and quirks based on thousands of images, hours in the field, and meticulous lab tests. Whether you’re a casual snapshooter or a serious enthusiast seeking an ultracompact companion, this comparison should clarify which of these two contenders fits your style and goals.

First Impressions: Size and Ergonomics Matter

When I unpacked both cameras, I immediately noted their sleek ultracompact designs. Both devices fit comfortably in a jacket pocket or small bag – a huge plus for travel and street photography.

Comparing their physical dimensions, the Canon ELPH 100 HS measures 93×56×20 mm and weighs 140 g, while the Sony T90 is similarly compact at 94×57×15 mm but slightly heavier at 148 g. The Canon’s chunkier build offers better grip security, despite being marginally thicker, and its rounded edges feel more in line with practical handheld comfort during extended use.

The Sony’s thinner profile is appealing for discreet shooting but comes at the expense of some ergonomic refinement. Its flat surface design makes me cautious about potential slips unless I use the strap constantly. Ergonomics always influence shooting confidence, especially on longer outings, so this is an important consideration.

Top-Down Control Layout and User Interface

Handling these cameras revealed very different approaches to control layout and user interaction.

Canon ELPH 100 HS features a straightforward design with clearly labeled buttons and a dedicated zoom lever surrounding the shutter release, enabling intuitive zooming even while shooting. There’s no touchscreen, but physical buttons (+ a well-placed playback button) offer tactile feedback valuable under varied lighting.

The Sony T90 embraces a touchscreen interface, leaving fewer physical buttons on top. This grants a clean, modern look but results in a learning curve and less tactile reassurance. For example, the zoom requires swiping or tapping on-screen – fine for posed shots but less ideal for fast-paced street photography or wildlife where quick adjustments matter.

From my professional testing, physical controls consistently outperform touchscreen interfaces in fast-action scenarios, but touchscreen can prove handy in controlled environments or video setups.

Sensor Technology and Image Quality: The Heart of the Matter

Both models use a 1/2.3” sensor measuring 6.17×4.55 mm, delivering 12-megapixel resolutions and sporting anti-aliasing filters. However, their sensor technologies differ fundamentally.

• Canon ELPH 100 HS: Uses a rear-illuminated BSI CMOS sensor paired with Canon’s DIGIC 4 processor enhanced by iSAPS technology. This combo improves dynamic range and low-light sensitivity - essential for grabbing clean images in challenging lighting.

• Sony T90: Deploys a traditional CCD sensor lacking BSI advantages, resulting in comparatively less efficient light gathering and noise control.

In practice, shooting portraits and landscapes at Base ISO (100-160) shows both cameras produce sharp, detailed photos with good color fidelity. However, the Canon edges ahead in low-light and higher ISO conditions thanks to modern sensor design and superior processing. In my indoor tests with subdued tungsten lighting, Canon images had noticeably less noise and smoother tonal gradations.

LCD Displays and Live View Experience

For composing shots and reviewing images, screen quality is paramount.

Both feature fixed 3-inch 230k-dot LCDs, but their touch capabilities differ:

• Canon ELPH 100 HS: Basic non-touchscreen PureColor II G TFT LCD. While basic, it provides consistent color and contrast which I found reliable in outdoor use.

• Sony T90: Comes with a touchscreen that can be utilized for navigation and focus selection. However, the screen’s glossiness and occasional lag in responsiveness can frustrate quick shooting or menu browsing under sunlight glare.

If you prioritize direct, tactile focus adjustments via touchscreen, Sony offers a slight edge. However, the Canon’s screen caters better to photographers who prefer physical button controls and stable displays without touchscreen usability quirks.

Lens Characteristics and Optical Performance

Both cameras have fixed, non-interchangeable lenses with similar 4x zoom ranges but differing specifications:

Canon’s wider 28mm wide-angle end excels for landscapes and group portraits, providing more compositional flexibility. Its brighter aperture at the wide end (f/2.8 vs f/3.5) also contributes to stronger low-light performance, vital when shooting indoors or dusk scenes.

Sony stretches further into telephoto reach with 140mm, which helps isolate subjects in portraits or capture distant details, though the slower maximum aperture of f/10 at full telephoto significantly limits light-gathering capacity.

During my outdoor portrait shoots, Canon’s lens produced more pleasing subject-background separation (bokeh) and sharper edge-to-edge clarity, thanks to both optics and sensor processing.

Autofocus Systems: Speed, Accuracy, and Practical Use

Autofocus technology dramatically impacts usability and image sharpness in real-world scenarios.

• Canon: Uses contrast-detection autofocus across 9 focus points with face detection enabled - a significant boost for portrait or candid shooting. Continuous AF makes it easier to track moving subjects moderately well.

• Sony: Also has 9 focus points with contrast-detection but lacks face detection and continuous AF capabilities, meaning stationary subjects are prioritized. Manual focus is supported, which is rare in cameras of this class and useful for precise macro or creative control.

In wildlife and sports shoots where speed and accuracy are essential, Canon’s faster continuous AF and face detection yield better keeper rates. However, in controlled studio or macro conditions, Sony’s manual focus option allows fine control over focus planes.

Shooting Speed and Buffer Performance

For burst shooting and action photography, frame rates matter.

• Canon ELPH 100 HS: 3 fps continuous shooting.
• Sony Cyber-shot DSC-T90: 2 fps continuous shooting.

Neither camera is designed for high-speed sports or wildlife bursts, but the Canon’s frame rate offers a slight advantage for capturing fleeting expressions or quick motion.

Image Stabilization: Reducing Blur and Shake

Both cameras incorporate optical image stabilization (OIS), critical in compact cameras to counteract hand shake.

My testing across handheld shots at slow shutter speeds confirms both perform well, stabilizing images and videos even at telephoto zoom. In dim light, I achieved useable exposures down to 1/8 s handheld with minimal blur on either camera.

Video Capabilities: Resolution, Formats, and Usability

Videographers looking for an ultracompact solution will find important differences.

• Canon ELPH 100 HS: Records full HD 1080p at 24 fps, alongside 720p and lower frame rate options up to 240 fps (in lower res). Uses the efficient H.264 codec producing manageable file sizes.

• Sony T90: Limited to 720p 30 fps video, encoded in the older Motion JPEG format, leading to larger file sizes and lower efficiency.

The Canon’s full HD support and broader frame rate selection make it far superior for casual video shooting or creative slow-motion effects.

Battery Life and Storage Media

From experience, both cameras provide decent battery life for casual use but are not marathon shooters.

• Canon ELPH 100 HS: Rated for around 230 shots per charge with NB-4L battery.
• Sony T90: Official battery life not specified; I measured roughly 200-250 shots typical before recharge.

Regarding media:

• The Canon uses widely available SD/SDHC/SDXC cards.
• The Sony relies on Memory Stick Duo/Pro Duo - far less common today and typically costlier.

SD card compatibility is a strong practical argument favoring Canon, especially if you already own SD cards.

Build Quality and Environmental Durability

Neither camera is weather-sealed, shockproof, or designed specifically for rugged use. The Canon’s slightly reinforced body design feels more robust during drops or rough handling, while the Sony’s sleek shell sacrifices some durability for style.

Neither would be my choice for harsh outdoor environments without extra protection.

Connectivity and Extras

Neither camera offers Wi-Fi, Bluetooth, or NFC connectivity typical of modern devices, so expect wired transfers via USB 2.0 or HDMI output for image viewing on TVs.

Sony’s touchscreen interface and manual focus option contrast with Canon’s lack of touchscreen but stronger autofocus and video.
