Casio’s notably slimmer profile stems from reduced lens zoom range and internal architecture optimized for portability versus extended reach.

Considering build quality, neither camera includes formal weather sealing or ruggedization, limiting outdoor use in adverse conditions. However, the SX510 HS features a more substantial grip and sculpted handholds offering greater in-hand stability during longer telephoto shots. Casio’s streamlined design favors discrete street shooting but sacrifices some ergonomic comfort for users with larger hands or extended operation sessions.

Control layouts further distinguish the two: Canon’s top view reveals clearly delineated mode dials and customizable settings buttons conducive to contextual manual overrides, including aperture/shutter priority modes. Casio’s controls are more limited, focusing on ease of use rather than advanced customization, which could frustrate users seeking extensive exposure control. Neither camera possesses an articulated touchscreen or electronic viewfinder.

Sensor Technology and Image Quality Fundamentals

A critical differentiator lies in sensor type and resulting image quality. The SX510 HS employs a 1/2.3-inch CMOS sensor with 12MP resolution, recognized for cleaner high-ISO performance and more agile responsiveness compared to CCDs, especially in challenging lighting. Conversely, the EX-H20G uses a 14MP CCD sensor of matching physical size, potentially offering slightly higher native resolution but with increased noise and slower readout speeds typical of CCDs.

Measured sensor areas are identical at approximately 28.07 square mm, resulting in the same crop factor of 5.8x relative to full frame. Both share a 3:2 or 4:3 aspect ratio option, but Canon also includes 1:1 and 16:9. Canon’s CMOS sensor favors improved dynamic range and color fidelity, while Casio’s CCD may introduce more color smearing and banding at elevated ISOs. Notably, neither model supports raw capture, necessitating JPEG-only workflows, limiting post-processing control.

Practical real-world tests confirm Canon consistently delivers cleaner results above ISO 800, with more retainable shadow detail and less aggressive noise reduction. Casio’s images exhibit somewhat more detail resolution at base ISO but degrade faster in low-light settings.

LCD and User Interface: Reviewing the Composition Experience

Both cameras provide fixed 3-inch LCDs with identical 461k dot resolution. However, differences in screen technology affect usability. Canon utilizes a TFT Color LCD, which delivers vibrant color reproduction and adequate outdoor visibility though limited viewing angles. Casio’s screen type is unspecified but less vivid, struggling under direct sunlight.

Neither incorporates touch interfaces, requiring reliance on physical buttons and controls. Canon’s interface design emphasizes clarity and quicker access to exposure parameters. Casio’s menus tend to be more basic, reflecting a consumer-oriented approach.

The lack of electronic viewfinders directs composition entirely via LCDs, which may challenge users in bright environments or with eyeglass wearers. Overall, Canon's screen and UI are more accommodating for extended shooting and manual adjustments.

Zoom Range and Lens Characteristics: Reach Versus Versatility

An area where the Canon SX510 HS excels is in its impressive 30x optical zoom lens covering an equivalent 24-720mm focal length range. This enables photographers to capture expansive landscapes, distant wildlife, or detailed sports action without swapping lenses - a significant asset in travel or fieldwork.

In contrast, Casio limits zoom to 10x optical coverage (24-240mm equivalent), still sufficient for general-purpose shooting but less capable of tight framing at long distances. For enthusiasts prioritizing telephoto reach, Canon clearly leads.

Aperture performance is comparable, with SX510 at f/3.4-5.8 and EX-H20G at f/3.2-5.7, both slow in telephoto but adequate in the wide end for moderate depth-of-field control. Neither lens includes fast apertures suitable for advanced low-light or bokeh effects.

Macro focus ranges reveal Casio’s advantage with minimum focusing distance of 7 cm, while Canon SX510 HS can focus to 0 cm nominally, but with less sharpness due to lens design. Casio probably offers a better macro experience for close-up shooters.

Autofocus Mechanisms and Shooting Speed: Precision Under Pressure

Canon’s SX510 HS uses a contrast detection AF with a single central focus point but also offers face detection and a rudimentary tracking system. This combination enhances focus accuracy on human subjects and enables slight object tracking, suited for casual portraits and some wildlife.

Casio's EX-H20G is limited to basic contrast detection AF with no face detection or tracking support, resulting in slower and potentially less reliable focus acquisition. This shortfall impacts action and wildlife photography more severely.

Continuous shooting speed of 4 frames per second on Canon supports better capture of fleeting moments compared to Casio, which does not specify continuous burst rates, indicative of modest capabilities. Sports photography demands precise, rapid AF and higher frame rates, a domain neither camera fully satisfies but Canon holds an edge.
