Gesture-driven interfaces and button placement significantly influence the speed and ease of operation during critical shooting moments.

• On the ELPH 510 HS, you’ll find a simplified control scheme with a mode dial and a ring control around the zoom lever, designed with casual users in mind. It lacks dedicated buttons for manual exposure modes.
• The G9 X II includes a manual control dial, exposure compensation button, and customizable function buttons. These additions empower photographers to react swiftly in more demanding situations.

I found the G9 X II's layout beneficial when rapidly adjusting aperture or shutter speed during dynamic scenes - a distinct advantage if you want creative exposure control on the fly.

Sensor Technology and Image Quality

Arguably the most fundamental aspect when choosing a camera is sensor size and quality, as these dictate detail rendering, noise performance, and dynamic range.

• The ELPH 510 HS sports a 1/2.3" BSI-CMOS sensor measuring 6.17x4.55 mm (approximately 28.07 mm² area) with 12-megapixel resolution. While this sensor size is standard for budget compact superzooms, it limits low-light performance and dynamic range.
• The G9 X Mark II boasts a much larger 1" BSI-CMOS sensor of 13.2x8.8 mm (about 116.16 mm²), packing 20 megapixels. This sensor size is a leap forward in image quality - delivering superior color depth, less noise at higher ISOs, and better tonal gradation.

During my testing in controlled studio and outdoor lighting, the G9 X II revealed finer details, richer colors, and less visible grain at ISO 800 and above compared to the ELPH 510 HS. The G9 X II recorded a DxO Mark overall score of 65, emphasizing its advantage in image quality.

Display and Interface

Image review and touchscreen usability are crucial, especially for on-the-go shooting and framing complicated compositions.

• Both cameras offer fixed, non-articulating LCDs - Canon sticking with a standard 3.2" display at 461k-dot resolution on the ELPH 510 HS, and a slightly smaller 3" but much sharper 1040k-dot screen on the G9 X II.
• Both use touch technology. The G9 X II's display is noticeably more responsive and vivid, which I appreciated in bright outdoor conditions - making menu navigation and touch focus more fluid.

Neither includes an electronic viewfinder (EVF), which potentially limits usability in direct sunlight. However, this is typical for their compact class.

Autofocus Systems and Manual Control

Autofocus speed, accuracy, and the option for manual focus can decisively affect photography outcomes.

• The ELPH 510 HS employs a contrast-detection AF system, with touch AF and basic face detection. It supports continuous AF and tracking but lacks any advanced focus area selection.
• The G9 X II also uses contrast detection but refines it with Canon’s DIGIC 7 processor, enabling faster and more precise focusing, plus selective AF area setting and touch focus.

In practice, I found the G9 X II much faster in locking focus, especially in low light and moving subjects. Manual focus is only available on the G9 X II, granting fine control in macro and creative shooting scenarios.

Lens Versatility and Optical Characteristics

Though both have fixed lenses, their focal ranges and apertures cater to different photographic priorities.

• Canon ELPH 510 HS features a 12x superzoom lens spanning 28-336mm equivalent (f/3.4-5.9). This massive zoom range is excellent for travel and casual wildlife attempts but suffers from limited sharpness and slow aperture at the telephoto end.
• Canon G9 X II offers a shorter 3x zoom (28-84mm equivalent) with a brighter aperture range of f/2.0-4.9, advantageous for low light and shallow depth of field.

In my hands-on shooting, the ELPH made long-distance subjects accessible, though image softness beyond 200mm required steadier hands or tripod support. The G9 X II, though limited in reach, excelled in portrait and street photography due to its wider aperture and finer optics.
