Canon G9 X vs Olympus SZ-11: Compact Cameras Put Through Their Paces

In my fifteen years as a camera tester and photographer, I’ve used countless compacts - both large sensor and superzoom varieties. Today, I’m diving deep into two intriguing representatives of the compact realm: the Canon PowerShot G9 X and the Olympus SZ-11. They cater to different user priorities and budgets but are often considered by enthusiasts seeking a pocketable yet competent camera.

I’ve spent extensive hands-on time with both these cameras across diverse photography situations, applying rigorous technical and real-world tests. This comparison doesn’t just regurgitate specs but weaves experience, industry-standard measures, and practical impressions into a thorough narrative. Whether you’re hunting for portrait quality, travel versatility, or wildlife reach, I’ll help you find the best fit.

Let’s start by putting their physical sizes under the microscope.

Size and Handling: Pocket-Friendly or Bulky Companion?

Both cameras emphasize portability, but they approach size and ergonomics differently. The Canon G9 X sports a slim, minimalist body, designed more like a large sensor compact aimed at enthusiasts craving quality and discretion. On the other hand, the Olympus SZ-11 leans into the superzoom compact niche, packing an impressively long 20x zoom into a slightly bigger chassis.

Looking side-by-side:

At just 98 × 58 × 31 mm and weighing 209 grams, the Canon is notably more pocketable. Its sleek and modern design fits snugly in most jacket pockets, making it an ideal grab-and-go solution. The Olympus, measuring 106 × 69 × 40 mm and weighing 226 grams, feels noticeably chunkier but offers an obvious trade-off with its extended zoom capabilities.

The G9 X’s smaller footprint comes with a robust metal construction which feels reassuringly solid in hand, despite limited grip protuberances. Its minimalist button layout emphasizes simplicity but may require menu diving for less frequent controls. Olympus SZ-11 opts for a more traditional compact shape with a slight grip bump, though its plastic build feels less premium.

In practice, if the camera’s to accompany you on casual street walks or social settings where a discreet, light setup is preferred, the Canon G9 X shines. If your priority tilts towards nature or travel where zoom reach is paramount, you might forgive the Olympus’s size penalty.

Top Controls and Interface: Who Wins the Usability Race?

Handling extends beyond physical size to how intuitive controlling the camera feels while shooting. In many of my tests, I observe first whether buttons, dials, and screens feel well laid-out for swift adjustments - essential for seizing decisive moments.

Examining their top views:

The Canon G9 X boasts a clean top deck with an intuitive mode dial supporting manual exposure modes such as aperture priority, shutter priority, and fully manual control. This is a rare advantage in compact cameras under $500 and places the G9 X closer to enthusiast-level shooting experiences.

The Olympus SZ-11, conversely, lacks dedicated mode dials or manual exposure. The shooter is restricted to fully automatic modes or scene presets. For beginners prioritizing ease over control, SZ-11’s simplicity can be an asset, yet for those accustomed to adjusting settings on the fly, it’s limiting.

Neither camera has an electronic viewfinder, but I find the G9 X compensates with a higher-resolution touchscreen on the rear.

Sensor and Image Quality: Large Sensor vs Superzoom Compromise

At the heart of image quality lies the sensor technology. Canon fitted the G9 X with a 1-inch backside-illuminated (BSI) CMOS sensor measuring 13.2 x 8.8 mm, with a resolution of 20 megapixels. Olympus, in contrast, employs a smaller 1/2.3" CCD sensor (6.17 x 4.55 mm) at 14 megapixels.

The G9 X’s sensor area is over four times larger than the SZ-11’s, and this matters greatly when battling noise, attaining dynamic range, and achieving shallow depth of field.

The following comparative diagram elaborates on sensor sizes and quality expectations:

In controlled lab tests and real-world shooting, the G9 X delivers markedly better color depth (DxOMark score: 21.5 bits vs not tested but expected less for SZ-11) and dynamic range of 12.3 stops, compared to what I observed as comparatively compressed tonal gradation on the SZ-11.

The G9 X’s 1-inch sensor enables cleaner images at ISO 125 through 12800, making it far more adept in dim conditions. Olympus tops out at ISO 1600 and is prone to noise intrusion beyond ISO 400. This is a huge factor for photographers shooting indoors, nighttime scenes, or low-light portraits.

In landscape photography, the higher resolution of the Canon combined with its sensor's dynamic range preserves highlight and shadow detail with superior fidelity.

Putting the Displays in Context

Although neither camera sports an electronic viewfinder, reviewing images and composing shots relies heavily on rear LCD quality and usability.

Here’s what I noted comparing both:

The Canon G9 X’s three-inch touchscreen is sharp at 1040k dots. The touch interface allows quick focus point selection and menu navigation, which is fluid during field shooting. This greatly enhances the shooting experience for photographers who appreciate tactile immediacy.

Olympus SZ-11’s fixed 3-inch TFT LCD, while adequate in daylight, has a lower resolution (460k dots) and no touch capability. This can make framing and reviewing images feel less crisp and slower to navigate.

In bright outdoor environments, the G9 X’s display holds up better to glare, improving compositional accuracy and interaction.

Autofocus and Shooting Speeds: Capturing Fleeting Moments

I took both cameras out to wildlife preserves and urban parks to test autofocus locking, tracking, and burst shooting - a trial I routinely run during field evaluations.

The Canon G9 X features contrast-detection autofocus with face detection, touch AF, continuous AF, and AF tracking modes. Despite lacking phase detection, its AF response is smooth and reliable in good light. The 6 fps continuous burst rate is respectable for its class.

Olympus SZ-11 uses contrast detection too but without advanced AF tracking. The 7 fps burst is slightly faster, but buffer limitations mean continuous shooting quickly slows down. The SZ-11 focuses slower, especially at telephoto zoom extremes, which can result in missed shots.

Neither camera supports eye detection or animal eye-af, as expected in this budget/compact category.

In low light, the Canon maintains better AF accuracy, thanks partly to its larger sensor and superior image processor (DIGIC 6 vs TruePic III+). The Olympus tends to hunt more and struggles with telephoto subjects.

Versatility Across Photography Styles

Portrait Photography

The G9 X’s f/2.0 wide-end aperture combined with its larger sensor allows more natural background blur or bokeh, giving portraits a more professional, model-like separation. Skin tones are rendered with better accuracy; I detected less noise and more subtle gradations in midtones when testing in mixed indoor lighting.

The Olympus SZ-11’s smaller sensor, slower lens (f/3.0–6.9), and limited control restrict creative portraiture possibilities, often resulting in evenly sharp but flatter images with less subject-background separation and heavier noise.

For portraits, the G9 X is a clear winner, especially paired with its manual controls that allow you to finesse depth of field and exposure.

Landscape Photography

Both cameras cover aspect ratios 4:3 and 16:9, allowing classic landscape framing. The G9 X’s higher resolution (20MP vs 14MP) and better dynamic range capture more detail in skies and shadows. Although the SZ-11’s 20x zoom seems tempting, landscapes usually benefit more from edge-to-edge image quality and wide-angle sharpness.

Neither camera has weather sealing; caution is advised in damp conditions.

Wildlife and Telephoto Use

This is where the Olympus shines. Its 25-500mm equivalent lens offers incredible reach in a pocketable form. For casual wildlife and bird photography, it's attractive.

Yet, AF speed and image quality at higher focal lengths lag noticeably. Telephoto images often exhibit softness and noise if lighting is suboptimal. The G9 X’s modest 28-84mm equivalent zoom limits framing diversity for wildlife.

Sports Photography

Given no dedicated phase detection AF or rapid burst buffer, neither camera is optimal here. The Olympus SZ-11’s 7 fps burst gives it a slight edge on sports action, but slow AF tracking and limited exposure controls hamper success.

The G9 X’s manual exposure and exposure compensation are helpful but burst rate of 6 fps is not competitive for fast-moving subjects.

Street Photography

The G9 X’s slim form, high image quality, and quiet mechanical shutter make it more suited to street and candid photography than the SZ-11, which feels heavier and more conspicuous.

The touchscreen focusing and quick ISO access on the Canon promote spontaneity, while Olympus lacks these refinements.

Macro Photography

With a 5 cm macro focus range, Canon has an edge here despite not being a dedicated macro camera. The SZ-11 reaches 1 cm, which is impressive for close subjects, but image softness at maximum zoom limits sharp results.

Neither offers focus stacking or bracketing.

Night and Astro

The Canon G9 X’s high ISO performance and 30-second minimum shutter speed allow more versatility for night and astrophotography with appropriate tripod use. The Olympus SZ-11’s max shutter speed is 2 seconds - too short for serious night work.

Video Features: Which is More Capable?

The Canon G9 X shoots Full HD 1080p up to 60 fps with H.264 compression, giving good quality video for social and casual use. Its touch AF in video mode assists with smooth refocusing.

Olympus SZ-11 maxes out at 720p video at 30 fps in Motion JPEG format, resulting in larger files and poorer compression efficiency.

Neither camera has microphone or headphone jacks, limiting audio quality or monitoring options.

Battery Life and Connectivity

The Canon G9 X manages approximately 220 shots per charge using the NB-13L battery. Connectivity includes built-in Wi-Fi and NFC, allowing instant image sharing - a valuable feature in today’s connected world.

Olympus SZ-11’s battery life is slightly lower at 200 shots, using the LI-50B battery. No wireless connectivity is onboard.

Both cameras accept SD/SDHC/SDXC cards in a single slot.

Durability and Build: Will They Last?

Neither camera offers weather sealing, dustproofing, or ruggedization. Both should be treated as delicate equipment with care in adverse conditions.

The Canon’s more metal-heavy construction offers longer-term confidence, while Olympus’s plastic body is less robust feeling.

What You Can Expect from the Lens Ecosystem

Both cameras use fixed-kits lenses but serve different philosophies.

The Canon G9 X’s 3x zoom (28-84mm equivalent) covers most everyday focal lengths with a wide, fast aperture at the short end, making it versatile for portraits and street shooting.

Olympus SZ-11’s 20x zoom (25-500mm equivalent) is a zoom king in this class, ideal if reach matters most, though with some trade-offs in speed and clarity at extremes.

My Full Performance Scores: Breaking It Down Numerically

Here’s a holistic view from my combined lab tests and field observations, translated into a normalized score out of 100:
