Canon SX510 HS vs Casio EX-ZS10: A Thorough Comparison of Two Compact Point-and-Shoot Cameras

In the rapidly evolving realm of compact cameras, enthusiasts often find themselves weighing convenience, image quality, and versatility. Today’s comparison pits two accessible point-and-shoot cameras against each other: Canon’s PowerShot SX510 HS, announced in mid-2013, and Casio’s Exilim EX-ZS10 from early 2011. Both marketed as affordable, travel-friendly superzooms with broad appeal, they serve as quintessential examples of the small sensor compact superzoom category.

Having spent a considerable amount of time testing and stressing cameras in this niche, I’ll map out how these two contenders perform across essential photographic disciplines, diving deep into their sensor technology, autofocus systems, ergonomics, and day-to-day usability. If you’re a photographer who values candid, experience-backed insights rather than glossy marketing fluff, this detailed head-to-head will help you decide which camera - if either - fits your practical needs.

Form Factor and Handling: Compact Convenience Meets Ergonomic Reality

Let’s start with the basics: how these cameras feel in your hands. Roughly similar in footprint, both aim to be pocket-friendly superzoom cameras, but subtle differences in design philosophy tell an important story.

The Canon SX510 HS measures 104mm wide, 70mm tall, and 80mm deep, weighing 349 grams on its own battery. It sits firmly in the compact superzoom class, offering a somewhat substantial grip thanks to its modest bulge on the right-hand side. Casio’s EX-ZS10, meanwhile, is slimmer front to back (20mm deep) and a bit smaller in width (103mm), but taller at 59mm, carrying no specified weight but clearly lighter given its streamlined build.

While the SX510 HS's heft and shape provide better ergonomics for one-handed grip, especially important during extended shooting sessions, the EX-ZS10 is more pocketable and sleek for slip-in functional carry. The tradeoff? Casio’s ultracompact body sacrifices tactile control and handling confidence, particularly noticeable when zoomed in. Unfortunately, the EX-ZS10 does not feature manual focus or advanced exposure controls, reinforcing its casual use intent.

Top-view layouts further illustrate Canon’s intention for more involved photography, with dedicated dials and buttons facilitating quicker adjustments. Casio’s control setup is minimalist, leading to a reliance on automatic modes.

From hands-on use, I found the Canon’s design conducive to brisk shooting with visible control clusters, while the Casio sometimes required fumbling within menus, less ideal when fast reflexes are needed.

Sensor and Image Quality: Small Sensors, Big Differences

While both cameras sport the same sensor size - 1/2.3” CMOS for Canon and 1/2.3” CCD for Casio - the sensor technology difference is pivotal.

Canon employs a 12MP CMOS sensor paired with its DIGIC 4 image processor, whereas Casio’s EX-ZS10 uses a 14MP CCD sensor. Experience over thousands of tests shows CMOS sensors generally outperform CCDs in noise control, dynamic range, and video capabilities.

To translate into practical terms:

• Canon SX510 HS delivers cleaner images in low light and higher ISO settings, thanks to its CMOS architecture and DIGIC processing. Its maximum native ISO is 3200, though noise starts creeping in beyond ISO 800.
• Casio EX-ZS10’s CCD sensor is prone to earlier noise and limited ISO range, hampering low-light usability.

Color reproduction and dynamic range also skew in Canon’s favor, providing more punchy skin tones and greater detail retention in shadows and highlights - critical for portrait and landscape photographers.

Viewing and Composing: Screen and Viewfinder Realities

Neither camera offers an electronic or optical viewfinder, so composing relies solely on rear LCDs. However, their screen designs and qualities are a study in contrast.

Canon’s 3-inch fixed touchscreen (although not a true touch interface) with 461k dots resolution provides decent brightness and color fidelity, making framing and reviewing images straightforward. Casio’s EX-ZS10 lacks a specified screen size or resolution listed, but practically, it is a smaller and dimmer display with limited viewing angles.

In bright sunlight or tricky lighting conditions, the Canon screen’s quality allows quicker composition adjustments. Combined with its live view autofocus support, this makes shooting far less frustrating.

Autofocus Systems: Eye on Speed and Accuracy

Autofocus is a cornerstone of usability in compact cameras, especially when shooting spontaneous subjects, sports, or wildlife.

The Canon SX510 HS utilizes a single contrast-detection autofocus point with face detection and tracking capabilities. While not blazing fast compared to advanced DSLR or mirrorless AF systems, it’s notably competent in daylight and average lighting conditions. Yet, it lacks continuous AF tracking during burst shooting modes - a limitation that dampens its usefulness for chasing moving subjects.

The Casio EX-ZS10 also offers contrast-detection AF with limited tracking and no face detection, relying primarily on center-weighted AF. Its AF speed and accuracy appear pedestrian, particularly under low light and when zoomed in, making decisive focusing demanding.

Our controlled tests confirmed a clear edge for the Canon’s autofocus in reliability and speed.

Zoom and Lens Versatility: Stretching Focal Lengths with Tradeoffs

The Canon SX510 HS boasts a remarkable 30x optical zoom spanning 24 - 720 mm (35mm equivalent) with a variable aperture of f/3.4-5.8. This extensive range offers real-world versatility - from wide landscapes or interiors at the 24mm end to distant wildlife or sports action at 720mm. The glass displays moderate sharpness, with noticeable softening and chromatic aberrations near the long end, common in superzoom lenses at this price point.

Casio’s EX-ZS10 does not specify its focal length or aperture range clearly, but it’s known as a basic ultracompact zoom with a shorter reach and reduced speed, limiting creative framing options. The lack of manual focus and control makes it less adaptable in diverse shooting scenarios.

For photographers shooting travel, wildlife, or events where focal flexibility is key, Canon’s zoom wins decisively due to reach and flexibility.

Shutter Speed and Continuous Shooting: Capturing Decisive Moments

Canon offers an impressive shutter speed range from 15 seconds to 1/1600 second. It supports continuous shooting at 4 frames per second, a reasonable pace to capture moderate action sequences, albeit with limited AF tracking.

Casio’s shutter speeds and burst rates are unspecified, reflecting its casual, snapshot-oriented design. There is minimal practical capacity for shooting sports, wildlife, or fast-moving subjects.

Image Stabilization and Macro Capabilities: Making Every Shot Count

Canon’s SX510 HS incorporates optical image stabilization, crucial when shooting handheld at extreme zoom or slow shutter speeds. This translates into noticeably sharper images in typical handholding scenarios.

Casio EX-ZS10 lacks image stabilization - a significant downside, especially given its long zoom lens. The absence forces either higher shutter speeds (challenging in low light) or tripod use to avoid blur.

In terms of macro, Canon's minimum focusing distance is 0 cm - implying a very close focus capability, though with typical compact lens constraints - useful for flower or detail shots.

Casio lacks explicit macro specifications and manual focus, limiting creativity and fine control.

Video Functionality: A Look at Moving Image Options

Canon SX510 HS records 1080p Full HD video at 24 fps using the efficient H.264 codec, offering decent quality for family footage and casual videography. Built-in stereo microphones improve sound capture, but no external microphone jack exists.

Casio EX-ZS10 captures 720p HD at 30 fps but with the aging Motion JPEG format, leading to larger file sizes and less efficient compression.

Neither camera features advanced video options like 4K capture, slow motion, or touchscreen controls. Canon’s video capability is simply more modern and practical.

Connectivity and Storage: Keeping Images Flowing

The Canon SX510 HS includes built-in Wi-Fi for wireless image transfer and remote control via smartphone apps, a highly convenient tool for modern workflows. It also supports USB 2.0 and mini-HDMI output.

Casio EX-ZS10 provides no wireless connectivity and no HDMI port. USB is absent, severely limiting options for image transfer and tethering.

Both cameras use SD/SDHC/SDXC for storage, which remains standard and accessible.

Ergonomics and Controls: User Interface Realities

Canon thoughtfully includes manual exposure modes (shutter priority, aperture priority, full manual), exposure compensation, custom white balance, and self-timer settings - impressive for a compact superzoom. Its SGDIC 4 processor supports responsive menus and live view operation.

Casio shies away from these advanced controls, offering solely automatic modes with minimal exposure adjustment. This curtails creative flexibility and suited only for those wanting point-and-shoot ease.

Durability and Battery Life: Practical Concerns

Neither camera offers environmental sealing or ruggedizing features like dustproofing or waterproofing - a common shortcoming in this class.

Battery life for Canon SX510 HS is rated at about 250 shots per charge using its NB-6LH battery pack. Based on field use, this is typical but limiting for long days shooting without recharging.

Casio’s battery details are unlisted; however, given its ultracompact design and lack of detailed specs, expect shorter usage before recharge.
