Canon PowerShot A1100 IS vs Canon PowerShot G7 X: A Hands-On Expert Comparison

Choosing a compact camera that fits your photography style is an intensely personal experience. Over the past 15 years of testing hundreds of Canon PowerShot models across genres, I’ve developed a keen sense of how subtle differences in sensor size, lens quality, and controls shape the results you capture. Today, I’m excited to compare two Canon compacts from different eras and segments: the entry-level Canon PowerShot A1100 IS (2009) and the enthusiast-oriented Canon PowerShot G7 X (2014). Through extensive real-world shooting and lab tests, I'll help you uncover which camera best suits your needs, whether you’re capturing family moments, landscapes, or street scenes.

First Impressions and Handling: Compact vs. Pocketable Powerhouse

At first glance, both cameras project the “compact” label, but their designs manifest different philosophies in size and ergonomics.

The A1100 IS is delightfully small and light (95x62x31mm, 150g, using AA batteries), making it a perfect pocket companion on casual outings. It feels straightforward with a fixed lens and minimal manual controls, inviting snapshooters to point and shoot without fuss. Its smaller footprint also means fewer grip contours - a tradeoff between portability and handling comfort.

In contrast, the G7 X definitely commands more presence in the hand (103x60x40mm, 304g). Despite not being dramatically larger, the added thickness and weight make for better stability, especially when composing images with manual focus or longer exposures. Its magnesium alloy build feels reassuringly solid, though it lacks any official weather sealing. The thoughtfully contoured grip and physical control dials provide tactile feedback I often found essential for quick adjustments in dynamic environments.

The top plate of the G7 X reveals a more sophisticated control layout: dedicated mode dial, exposure compensation dial, custom function buttons, and a responsive shutter with a two-stage focus/release. The A1100’s top controls are pared back, focusing largely on a mode dial and shutter button - perfectly fine for beginner shooters but limiting when creative manual control is preferred.

Verdict: If pocketability and ease of use are your priority - perfect for street, travel, and casual snapshots - the A1100 IS excels. For those craving more manual control, confidence in grip, and a robust professional feel without bulk, the G7 X offers a clear edge.

Sensor Technology and Image Quality: Small Sensor vs One-Inch BSI-CMOS

Image quality is where these cameras diverge radically, largely due to their sensor technology.

The Canon A1100 IS features a conventional 1/2.3-inch CCD sensor with 12 megapixels, common for the era and small sensor compacts. This sensor measures roughly 6.17 x 4.55mm, offering a sensor area of 28.07 mm². While fine for daylight and casual shooting, it inevitably struggles in low-light situations, resulting in noise and limited dynamic range. The older CCD tech also translates to slower readouts and less efficient power consumption.

The Canon G7 X steps up in a meaningful way with its 1-inch BSI-CMOS sensor, measuring 13.2 x 8.8mm (116.16 mm²) at 20 megapixels, almost four times the sensor area of the A1100. The back-illuminated design allows the sensor to capture light more efficiently, boosting high ISO performance and dynamic range substantially. According to DxO Mark, the G7 X scores 71 overall, ranking it well within the enthusiast compact segment - even today delivering excellent image quality at ISO levels up to ISO 800 and usable beyond that.

I tested both cameras under identical conditions, shooting an early morning street scene and interior low light portrait:

• The A1100 IS images are noticeably softer, with muddied shadow detail and visible noise creeping in at ISO 400 and above. Skin tones appear flatter, and fine patterns like fabrics lack texture.
• The G7 X produces cleaner, sharper images with vibrant yet natural skin tones and superior separation of highlights and shadows. At ISO 800 and even ISO 1600, noise is controlled well enough to produce usable prints.

Practical tip: If image quality is paramount - especially in challenging lighting - investing in a larger sensor camera like the G7 X will pay dividends.

Lens and Focal Range: Bright Zoom vs. Flexible Zoom

Lens specs tell an important part of the story.

• A1100 IS: 35-140mm equivalent (4x zoom), max aperture F2.7-5.6
• G7 X: 24-100mm equivalent (4.2x zoom), max aperture F1.8-2.8

The A1100’s lens is serviceable with a modest zoom range geared towards general snapshots. Its aperture range closes down significantly at longer focal lengths, limiting depth of field control and low-light ability.

The G7 X’s faster aperture lens is a watchword for low-light capability and creative control. The wide F1.8 together with a slightly wider 24mm equivalent gives flexibility - from sweeping landscapes and environmental portraits to detail-rich street shots. Sharpness across the frame from wide to telephoto is excellent, especially centrally, with minimal distortion or chromatic aberration.

From my testing: The bright lens on the G7 X shines in shallow depth of field portraits, producing beautifully creamy bokeh that helps isolate subjects (eyes are rendered crisply, aided by the camera’s face detection autofocus). The A1100 IS’s slower lens yields flatter images with less background separation.

Autofocus Systems: Contrast Detection Meets Modern Flexibility

Autofocus can make or break your shooting experience, particularly with moving subjects.

The A1100 IS employs a basic contrast-detection system with 9 focus points but no continuous AF or advanced tracking. It performs adequately in good light but can be sluggish or “hunt” under dim conditions. Face detection helps for casual portraits but lacks sophistication.

The G7 X advances with a 31-point contrast-detect AF system, incorporating touch-to-focus on the LCD and improved AF accuracy. While it does not feature phase-detection pixels, AF speed and reliability are markedly better in my hands, locking focus quickly on static and moderately moving subjects. It supports AF continuous mode for stills, which benefits event or street photography.

In wildlife or sports, neither camera is a top choice, but the G7 X’s faster AF helps capture fleeting moments with higher keeper rates. The A1100 IS’s single-shot AF and 1 frame per second burst rate significantly hamper action shooting.

Display and User Interface: From Fixed View to Tilt and Touch

The rear LCD is your main compositional aid, especially without electronic viewfinders.

The A1100 IS has a small 2.5-inch fixed LCD with 115k-dot resolution, which often felt underwhelming in bright sunlight due to its limited brightness and lack of tilting or touch input. The optical tunnel viewfinder is basic and unhelpful in tricky lighting.

The G7 X sports a larger 3-inch tilting touchscreen with 1.04 million dots, allowing flexible framing from awkward angles - very handy for low or high shots on the street or macro work. The touch interface made selecting AF points and navigating menus refreshingly convenient during my tests. The lack of any EVF may dissuade some, but the bright responsive LCD compensates well.

Video Features: Basic VGA vs Full HD with Stabilization

If video matters, it’s another area where the G7 X outperforms.

• The A1100 IS only offers VGA 640x480@30fps capture using Motion JPEG compression - adequate for rudimentary clips but not serious video. No mic input or HDMI out limits post-production options.

• The G7 X records Full HD 1080p video at 60 fps in H.264/MPEG-4, delivering smooth, detailed footage. Optical image stabilization reduces camera shake effectively for handheld shooting. It also supports time-lapse video, a bonus for creative projects. However, it lacks microphone/headphone jacks, constraining audio quality unless you use indirect solutions.

For casual video combined with stills, the G7 X’s capabilities are clearly superior, matching the demands of modern social media creators and vloggers.

Battery Life and Storage: Convenience vs Efficiency

Both cameras share a single card slot compatible with standard SD cards, though the G7 X supports faster UHS-I speeds for rapid write times.

The A1100 IS uses easily replaceable AA batteries, a practical choice for travel in remote locations. However, battery life varies significantly based on brand and capacity, and performance is often modest when compared to lithium-ion options.

The G7 X has a proprietary NB-13L battery pack, rated for about 210 shots per charge in my testing - a moderate rating for a compact enthusiast camera. Carrying spares is advisable for full-day shoots. The Samsung or Panasonic batteries of the era have improved over time, but extended use intensifies the need for recharge planning.

Connectivity: From None to Basic Wireless Features

Connectivity is another area reflecting their time gap.

• The A1100 IS offers no wireless options; USB 2.0 is the sole means to transfer images. This adds friction for today’s instant sharing culture.

• The G7 X includes built-in Wi-Fi and NFC, enabling remote control via smartphone and seamless image transfers without cables. HDMI output is also provided for viewing images or video on TVs, a feature absent in the A1100 IS.

Durability and Weather Resistance

Neither camera has environmental sealing, dustproofing, or waterproofing features. The G7 X’s metal chassis does offer a durable shell, while the A1100 IS’s plastic body is more vulnerable to impacts and wear. For outdoor photography in challenging weather, an additional protective case or bag is recommended for both.
