Canon ELPH 510 HS vs Casio EX-100: An In-Depth Comparison for Enthusiasts and Professionals

In the ever-evolving world of compact superzoom cameras, two models catch the eye for their intriguing balance of portability and feature set: Canon’s ELPH 510 HS and Casio’s EX-100. Although both belong to the small sensor superzoom category, these models, unveiled two years apart (2012 and 2014 respectively), present distinct approaches to image-making that deserve a thorough appraisal - especially for photographers seeking solid performance in compact bodies.

Having extensively tested both cameras across multiple photography genres, I will provide an honest, data-driven comparison. We’ll unpack their sensor technologies, autofocus systems, usability, and real-world outcomes to help you decide which might best suit your photographic endeavors, be it travel, street, portraits, or more specialized use cases.

Carrying Convenience and Handling: Size Matters

First impressions count, especially when size and ergonomics affect how often you’ll actually bring the camera along. The Canon ELPH 510 HS is featherlight and slim at just 206g and 99x59x22mm. The Casio EX-100 is notably bulkier and heavier at 389g and 119x67x50mm - nearly double the weight and nearly triple in thickness.

The Canon feels slim and pocketable, ideal for street and travel photography where discretion and mobility matter. I found its rounded edges and minimalist button layout facilitate quick grabs and one-handed operation. However, its smaller footprint sacrifices some tactile controls and grip comfort.

Conversely, the Casio EX-100’s larger chassis offers a firmer grip and more substantial control layout - advantageous for longer shooting sessions and precision manual focusing. The heft and size, though, make it less convenient for casual carry but still bearable in a jacket pocket or small camera bag.

Design, Controls, and User Interface: Balancing Simplicity and Versatility

A camera’s top and rear control architecture significantly influence how effectively you can exploit its features. Let’s look at their design philosophies side by side.

Canon’s ELPH 510 HS opts for streamlined simplicity. Its top panel sports a minimalistic shutter and zoom rocker, with a single mode dial absent - highlighting its beginner-focused orientation. The back features a 3.2-inch PureColor II TFT touchscreen with a modest resolution of 461k dots. Touch-enabled autofocus and menu navigation give it a contemporary feel, but lack of an electronic viewfinder (EVF) and physical dials limit versatility.

On the other hand, Casio’s EX-100 brings traditional enthusiast controls into a compact package: dedicated dials for shutter speed and aperture afford full manual exposure control - rare for compacts in this class. Its 3.5-inch Super Clear LCD tilts upward and boasts a dense 922k dot resolution, significantly aiding composition and focus accuracy in varied shooting angles though it lacks touchscreen capability. The button layout is more extensive but intuitive once you familiarize yourself.

The EX-100’s more tactile experience rewards photographers who prefer manual tweaking, while the ELPH 510 HS targets ease of use for point-and-shoot convenience.

Sensor Technology and Image Quality: Punching Above Their Weight?

Sensor performance is pivotal, especially in small sensor superzooms where size limits light gathering. Here, the Casio edges ahead with a larger sensor.

Canon ELPH 510 HS:

• 1/2.3" BSI-CMOS sensor (6.17 x 4.55mm)
• 12MP resolution (4000 x 3000 max)
• Max native ISO 3200
• No RAW support
• Antialias filter enabled

Casio EX-100:

• Larger 1/1.7" CMOS sensor (7.44 x 5.58mm)
• Same 12MP resolution (4000 x 3000 max)
• Much higher ISO range, 80 to 12800 native, with boosted ISO 25600
• RAW capture enabled
• Antialias filter present

That nearly 50% larger sensor area of the EX-100 provides a stronger foundation for image quality, particularly in noise control and dynamic range. In controlled tests, I noticed the Casio delivers cleaner shadows and richer color gradations under subdued lighting, thanks in part to sensor-shift image stabilization and wider aperture (f/2.8 vs f/3.4-5.9 on the Canon).

The Canon's smaller sensor with a narrower aperture makes it less adept in low light and more prone to noise when pushed toward ISO 3200. Also, lacking RAW file output restricts post-processing latitude - an important consideration for serious shooters.

In daylight conditions, both cameras capture sharp details, but the Casio’s slight advantage in optical quality and sensor size results in subtle edge-to-edge sharpness improvements and smoother tonal transitions.

Autofocus Systems: Speed and Accuracy in Real Use

Autofocus (AF) is critical in many photography styles. Both cameras utilize contrast-detection AF systems typical for their class, but implementation differs.

Canon’s ELPH 510 HS uses a face detection system with continuous AF available during live view, complemented by touch AF on its LCD. The focal range 28-336mm equivalence (12x zoom) affords good reach albeit with lens aperture narrowing at telephoto. AF speed is moderate; in my testing, subjects under steady light lock quickly, but the system struggles in low light and moving subjects.

Casio EX-100 improves with 25 focus points, center-weighted metering, and competitive continuous AF tracking. Moreover, its manual focus ring and shutter/aperture dials empower deliberate focus and exposure control - a rare find here. In wildlife or sports shooting scenarios, the EX-100 achieves a faster, more reliable focus lock and better tracking of moving subjects, especially with consistent ambient light.

While neither is a professional-grade AF powerhouse, the Casio is clearly superior for action or dynamic shooting given its 30 fps burst mode (versus 3 fps on Canon), facilitating sharper sequences of fast action.

Display and Live View: Composition Confidence

The rear LCD is your window into the scene and critical for framing and reviewing shots - especially on compact cameras without viewfinders.

Canon’s ELPH 510 HS sports a 3.2-inch fixed touchscreen with decent color reproduction and brightness but limited resolution. It’s responsive for taps and swipes, easing AF point selection, but fixed angle means awkward shooting positions may force guesswork.

The Casio EX-100’s 3.5-inch LCD is brighter and nearly twice as sharp. Although non-touchscreen, its tilt mechanism and display clarity provide tremendous flexibility when shooting at low or high angles - a compelling advantage for macro, street, or landscape photography.

I found the Casio’s display vastly improves live view focusing accuracy and manual control efficacy, a nod to its enthusiast orientation.

Versatility Across Photography Genres: Who Wins Where?

Let’s analyze how these cameras perform in practical photographic scenarios, based on extensive real-world field testing.

Portrait Photography: Rendering Skin and Background Blur

Canon’s limited aperture range (f/3.4-5.9) combined with a small sensor restricts bokeh potential. Face detection AF enhances subject sharpness but eye-detection or animal eye AF is absent.

Casio’s faster f/2.8 lens aperture at wide angle delivers noticeably better subject-background separation, even with the small sensor. The EX-100’s 25-point AF and face detection achieve precise focus on eyes, enhancing portrait quality.

Verdict: Casio EX-100 edges ahead for portraits thanks to faster aperture, better focusing, and superior detail resolution.

Landscape Photography: Detail, Dynamic Range, and Weather Readiness

Small sensors typically limit dynamic range, but the Casio’s larger sensor and RAW support give it a clear advantage when capturing nuanced shadows and highlights in landscapes. Its longer minimum shutter speed (up to 1/20000s) and manual exposure modes allow precise control in bright daylight.

Canon’s ELPH 510 HS is less flexible, lacking manual modes and with a narrower dynamic range. Both lack weather sealing, so landscape outings in harsh conditions require caution.

Wildlife and Sports: Tracking, Speed, and Reach in the Field

With a 12x (28-336mm equivalent) zoom range, the Canon ELPH 510 HS superficially seems ideal for distant subjects. However, the slower burst rate (3 fps) and modest AF tracking performance limit its suitability for fast action. Its narrower aperture also reduces light intake at longer focal lengths, challenging autofocus and image quality.

The Casio EX-100 has a slightly shorter zoom (10.7x, 28-300mm equivalent) but faster burst shooting at 30 fps, alongside more aggressive AF tracking and manual focus controls allowing for jugging shots and deliberate framing.

For wildlife or sports shooters reliant on swift responsiveness, the Casio is clearly the stronger candidate.

Street Photography: Discretion, Reactivity, and Mobility

Here, the Canon ELPH 510 HS shines with its compactness, light weight, and quiet operation. Its touchscreen makes swift changes to exposure and focus straightforward, and the fixed lens zoom covers common street focal lengths.

The Casio EX-100 is bulkier with louder button clicks and slower startup times. Its manual control dials add complexity where speed and stealth might be preferred.

Thus, for candid street photographers valuing discretion and ease of use, the Canon remains the better fit.

Macro and Close-Up: Focusing Precision and Magnification

With a minimum focus distance of 1cm, the Canon ELPH 510 HS impresses for macro photography, allowing subjects to be captured with extreme proximity. Image stabilization further aids handheld close-ups.

Casio’s minimum focus of 5cm, although good, restricts ultimate magnification slightly. However, its manual focus ring and image stabilization offer refined control and sharpness improvements.

Both are capable macro performers for casual experimentation, but Canon’s closer focus edge gives it a slight advantage.

Night and Astrophotography: High ISO and Shutter Speeds

Astro enthusiasts or night shooters will appreciate Casio’s ISO sensitivity ceiling of 12800 (boosted 25600) paired with a max shutter speed of 1/15s on the Canon vs 1/20000s on the Casio. The EX-100’s higher native ISO range and manual exposure modes empower creative long exposures and noise balancing.

Lacking RAW on the Canon reduces post-processability of noisy images.

For low-light or night shooting, Casio’s EX-100 is the recommended tool.
