Canon PowerShot G9 X Mark II vs. Olympus Stylus SH-3: A Comprehensive Comparison for Serious Enthusiasts

When evaluating compact cameras, enthusiasts and pros alike are drawn to two compelling models in recent memory: the Canon PowerShot G9 X Mark II (henceforth Canon G9 X II) and the Olympus Stylus SH-3 (Olympus SH-3). These cameras, released within a year of each other, aim to deliver advanced photographic capability in compact, portable bodies - albeit targeting somewhat different use cases and priorities.

Over the course of extensive hands-on testing and technical analysis - covering lab benchmarks, varied shooting conditions, and real-world scenarios - I've dissected each camera's design, performance, and value. This article delves deeply into every facet, from sensor technology to autofocus, from image quality to ergonomics, helping you pick the right tool for your photography passions.

Getting to Know the Contenders: Size, Design & Build

If portability is paramount, understanding size and ergonomics is the logical starting point. The Canon G9 X II is a large-sensor compact camera, designed with sleek minimalism, while the Olympus SH-3 is a small-sensor superzoom, embracing versatility in reach at the expense of bulk.

Physically, the Canon is decidedly more pocketable at 98 x 58 x 31 mm, weighing 206 grams, compared to Olympus's chunkier ~109 x 63 x 42 mm and 271 grams. The Canon's slim profile lends itself brilliantly to street and travel photography - discreet, lightweight, and easy to slip into any bag. The Olympus’s size, while still respectable for a superzoom, is notably larger and heavier.

This difference is inherently tied to their designs: Canon sacrifices extreme zoom range for a larger sensor and brighter optics, Olympus offers a powerhouse 24x zoom in a compact body. Build quality on both is competent but not weather sealed - no surprise at their price points - so avoid harsh weather conditions unless you have protective housing.

Top-Down: Controls and Operational Ergonomics

Turning from size to handling, let’s compare their control layouts and user interface responsiveness.

The Canon G9 X II impresses with an intuitive top-plate layout, featuring a mode dial including PASM modes plus customizable buttons, appealing to photographers who like manual control without getting overwhelmed. The DIGIC 7 processor delivers fast responsiveness including quick autofocus acquisition and burst shooting.

The Olympus SH-3 offers slightly more shooting speed with its max continuous shooting at 11.5 fps, compared to Canon’s 8.2 fps. However, Olympus sacrifices exposure modes - you won’t find dedicated shutter or aperture priority modes here, though manual exposure is supported.

I found the Canon's well-routed buttons and tactile dials more satisfying and accessible for experienced users wanting quick adjustments. Olympus’s glossy finish and minimalist button layout aid casual shooting but may frustrate those craving deeper, hands-on exposure tweaks.

The Heart of the Matter: Sensor Technology and Image Quality

Arguably the single most crucial factor affecting image quality is the sensor. Beyond specs, I conducted standardized lab tests and field shoots comparing dynamic range, color fidelity, and noise performance.

Sensor Sizes & Types

• Canon G9 X II 1" BSI-CMOS sensor (13.2 x 8.8 mm), effective 20 MP resolution
• Olympus SH-3 1/2.3" BSI-CMOS sensor (6.17 x 4.55 mm), 16 MP

The Canon’s larger sensor captures over four times the surface area of Olympus, which translates into tangible advantages: improved dynamic range (~12.5 stops), richer color depth, and cleaner files at high ISO. The G9 X II’s DxOMark overall score of 65 testifies to this advantage. Olympus, unfortunately, hasn't been officially benchmarked by DxOMark, but smaller 1/2.3” class sensors historically trail in head-to-head tests.

Real-World Impact

In natural light, the Canon produces images with less noise and more natural skin tones - a boon in portrait work. The Olympus, while sharp, struggles in shadows and low light, where noise and detail loss become apparent.

Viewing and Composing: LCD Screens and Viewfinders

Neither camera offers a viewfinder, electronic or optical, which is important for those shooting bright outdoor scenes. Both compensate with a 3" fixed LCD touchscreen, but quality differs.

The Canon’s screen resolution of 1040k dots smokes Olympus's 460k dots, delivering a sharper, brighter display with better color accuracy and touch responsiveness. This difference matters when framing complex scenes or reviewing images on the go in challenging lighting.

The lack of articulated or tilting screens on either is a missed opportunity, particularly for macro and low-angle shooting. However, the Canon’s better display quality and touch autofocus functionality make manual focus and menu navigation more pleasant.

Portrait Photography: Rendering Skin Tones and Bokeh

Portrait photographers demand accurate skin tones, precise autofocus (notably eye detection), and pleasing background separation.

• Canon G9 X II offers face detection with contrast-detect AF and a bright f/2 aperture at 28mm equivalent, facilitating smoother backgrounds.
• Olympus SH-3 lacks dedicated eye detection and maxes out at f/3.0 at wide angle, limiting bokeh potential.

In my portrait sessions, the Canon’s 1” sensor and lens speed rendered appreciably better subject isolation and natural skin tones. Eye detection, while not on par with modern mirrorless, is reliable enough in decent light. Olympus' superzoom lens tends to have busy bokeh due to slower apertures and smaller sensor depth of field.

Conclusion: Canon G9 X II is unequivocally the more capable portrait tool, especially for enthusiasts wanting tight focus control and subtle tonal gradations.

Landscape: Resolution, Dynamic Range and Robustness

Landscape shooters prioritize resolution, dynamic range, and weather sealing.

The Canon’s 20-megapixel sensor yields images with more detail and dynamic range (12.5 stops measured in lab), enabling great shadow recovery and subtle highlight roll-off. Olympus offers slightly lower effective resolution (16 MP) and narrower dynamic range due to sensor size.

Both cameras lack environmental sealing; you'll want covers or careful handling in wet or dusty environments.

Despite Olympus’s advantage in focal length reach, the wider aperture and larger sensor on Canon mean it excels in capturing crisp, richly textured landscapes with vibrant colors and less noise. The Canon's ISO sensitivity up to 12800, combined with effective noise control, also aids twilight or dusk shots.

Wildlife Photography: Autofocus Speed and Telephoto Reach

For those chasing wildlife, autofocus performance and telephoto capabilities are crucial.

• Olympus SH-3 boasts a 25-600 mm (24x) zoom equivalent, superior for distant subjects.
• Canon G9 X II offers only a modest 28-84 mm (3x) zoom.

While Canon’s autofocus uses contrast-detection only (no phase detection) and is optimized for speed with the DIGIC 7 processor, Olympus’s TruePic VII processor powers continuous AF and tracking mode at higher burst speeds.

Olympus’s extended zoom allows framing distant wildlife without teleconverters or lens swaps. However, image quality at full telephoto is constrained by small sensor noise, modest aperture, and lens sharpness. Meanwhile, Canon produces sharper, cleaner images but from much closer range.

In field testing, Olympus’s autofocus “kept up” during slow-moving birds and animals better than expected for a compact, but struggled in low light. Canon’s autofocus accuracy was impeccable in good lighting but slower at tracking erratic subjects.

Recommendation: Olympus SH-3 is the better “reach” choice for casual wildlife shooters; Canon G9 X II suits those prioritizing image quality over focal length.

Sports Photography: Tracking, Low Light, and Burst Speed

Sports demand fast continuous shooting and dependable AF tracking.

• Olympus SH-3’s 11.5 fps burst rate trumped Canon's 8.2 fps in raw speed.
• Both use contrast-detection AF, limiting predictive tracking in fast action.
• Canon processes images slightly faster, reducing frame lag.

Tested outdoors with moving subjects, Olympus’s higher frame rate theoretically offers an advantage, but the slow autofocus system in both cameras means missed focus is a concern in really fast sports. Neither offers DSLR-like tracking sophistication.

Low light performance favors Canon’s larger sensor and better noise handling, critical for indoor or dusk events.

If your goal is occasional sports snapshots and zoom range, Olympus’s SH-3 excels; for better noise and image quality in challenging light, Canon takes precedence. Neither are top-tier sports cameras but serve casual enthusiasts.

Street Photography: Discretion, Portability, and Low Light Agility

Street photographers prize small size, swift focus, and discreet operation.

Canon G9 X II’s slim profile, muted operation, and better low light ISO performance suit candid street shooting perfectly. Olympus SH-3's larger size and slower aperture make it more conspicuous and less nimble.

Face detection focus, responsive touchscreen, and silent shooting mode on Canon support a discreet shooting style.

In my urban street tests, Canon struck the right balance - light enough to carry all day, responsive enough for quick snaps, and image quality that holds up for gallery-quality prints.

Macro Photography: Close Focus and Stabilization

Macro enthusiasts look for minimum focus distances, magnification, and effective stabilization.

• Canon G9 X II’s macro focusing starts at 5cm, Olympus at 3cm, giving Olympus a slight edge on working distance.
• Olympus features sensor-shift stabilization, beneficial when shooting handheld close-ups.
• Canon uses optical stabilization.

While Olympus allows closer focusing with longer zoom range, the Canon’s brighter optics and cleaner sensor produce sharper macro shots in better detail, despite slightly longer working distance.

Mechanically, neither supports focus stacking or bracketing, limiting depth range control. For casual macro, both suffice; Canon edges out with cleaner detail rendering.

Night and Astrophotography: ISO Performance and Exposure Control

Low light performance pits Canon’s 1" sensor and max native ISO 12800 against Olympus’s small sensor max ISO 6400.

Testing night scenes and star fields, Canon’s cleaner files and dynamic range shine. Olympus’s smaller sensor reveals more noise at ISO above 800, limiting astrophotography potential.

Canon’s manual exposure modes and longer shutter speeds (up to 30 seconds) give flexibility for night shooting; Olympus matches min/max shutters speeds but lacks manual priority modes.

Hence, Canon G9 X II is the preferred companion for low-light enthusiasts or budding astrophotographers.

Video Capabilities: Recording Quality and Stabilization

Videographers will find interesting contrasts:

• Canon records up to Full HD 1080p @ 60fps with MOV H.264 codec.
• Olympus adds a 4K UHD mode at 15fps (not ideal for motion), plus 1080p60.

Neither camera supports external microphones, headphones, or advanced video features. Both rely on optical or sensor-shift stabilization, greatly aiding handheld footage.

Canon’s video autofocus is smooth though occasionally hunts in low light. Olympus's 4K mode offers future-proofing but the low frame rate limits utility for action shots.

For casual video, Canon’s smoother frame rates and codec edge out; Olympus offers quirky 4K capture as a bonus.

Travel Photography: Versatility, Battery Life, and Connectivity

Travelers need all-round versatility and reliable battery life.

• Olympus SH-3 comes with 380 shots per charge, significantly better than Canon’s 235.
