Canon PowerShot SX510 HS vs Casio Exilim EX-Z270: A Thorough Hands-On Comparison

When it comes to compact cameras, the market offers an intriguing spectrum - from pocket-sized ultracompacts to superzoom beasts promising everything but the kitchen sink. Today, we’re diving deep into two models that sit on opposite ends of that realm: the Canon PowerShot SX510 HS, a 2013 superzoom stalwart, and the 2009 Casio Exilim EX-Z270, an ultracompact designed for everyday snapshots. Both aim to serve casual shooters but from very different angles.

Having personally tested hundreds of compacts from various brands over the years, I find comparisons like this fascinating because they force us to weigh zoom range against portability, sensor size against processing power, and more. So, pull up a chair and let’s unpack what these cameras truly offer - beyond the spec sheets and marketing fluff.

Size and Handling: Superzoom vs. Pocket-Friendly

Right out of the gate, size is the elephant in the room. The Canon SX510 HS is notably larger and chunkier than the Casio EX-Z270, and this difference becomes stark once you hold both in hand.

Looking at the Canon’s 104 x 70 x 80mm footprint, it occupies more real estate in your hand and bag - but that bulk introduces some ergonomic benefits. The Canon sports a heftier 349g weight (battery included), which translates into a more stable shooting platform, especially at super telephoto settings. Grip comfort is enhanced by the pronounced handhold and physical buttons.

On the flip side, the Casio EX-Z270 is ultra-svelte at 97 x 55 x 22mm, practically slipping into a jeans pocket, weighing just 111g, making it an excellent companion for casual shooters who want a seriously portable device without the hassle of carrying a camera bag.

However, this compactness comes at the cost of ergonomics: the EX-Z270’s tiny size means fiddly buttons and less room for a comfortable grip, often leading to tentative handling, especially in variable shooting conditions.

So, in short: if your priority is size and stealth, Casio wins. If you want better ergonomics and more physical presence - especially for longer focal lengths - Canon is your buddy.

A Tour of Controls and Interface

Handling a camera is as much about how it feels as it is about what controls you have at your fingertips. Let’s get under the skin of these two with a look at their top layouts.

The Canon SX510 HS features a fairly traditional compact layout, with a mode dial offering PASM controls (shutter and aperture priority!), manual exposure control, and custom modes - a boon for enthusiasts wanting more creative input. The rear panel has a clear LCD with physical buttons for ISO, exposure compensation, menu, and playback.

The Casio EX-Z270, on the other hand, leans towards simplicity. Its top plate has fewer buttons, no dedicated mode dial, and lacks shutter or aperture priority modes entirely. Instead, it favors straightforward automatic shooting modes, appealing to those seeking simplicity over complexity.

No touchscreens here - both have non-touch TFT LCDs (a drawback in today’s touchscreen-driven world), though Canon’s screen is marginally larger and more resolute.

Sensor Technology and Image Quality: What the Numbers Reveal

For photographers - whether casual or serious - the sensor is kingdom. It largely governs image quality, noise control, dynamic range, and color rendition. Here are the key specs side by side:

Now, before you roll your eyes at the mere fractions-of-an-inch sensor sizes, let's remember these cameras are compact segment players designed for convenience and versatility, not for studio-grade performance.

Nonetheless, the Canon SX510 HS enjoys a clear advantage with a 1/2.3" CMOS sensor. Compared to the Casio’s 1/2.5" CCD sensor, this translates to better noise management at higher ISOs, quicker sensor readout speeds for video, and more power-efficient processing. The Canon's 12-megapixel resolution offers marginally increased detail but more importantly enables better interpolation for cropping and printing.

The Casio’s CCD sensor is dated technology at this point and tends to struggle more with noise beyond ISO 400–800, producing softer images overall. Its max ISO of 1600 rarely comes in handy because images degrade quickly.

Neither camera supports RAW output, which means you’re stuck with compressed JPEGs - a big limitation for enthusiasts wanting post-processing flexibility. Unfortunately, no surprises there given the era and market segment.

Lens and Zoom: Stretching the Focal Range

Arguably the Canon SX510 HS’s biggest selling point is its 30x optical zoom lens, ranging from 24mm wide-angle up to a whopping 720mm equivalent. That's a seriously versatile zoom for any small sensor camera.

The Casio EX-Z270 sports a more modest 4x zoom, spanning 28-112mm equivalent focal lengths - still adequate for everyday snapshots but nowhere near the reach of the Canon.

However, this extreme zoom stretch in the Canon comes with some optical compromises: maximum aperture narrows from F3.4 at the wide end down to F5.8 at telephoto, which means less light gathering and more reliance on stabilization at longer focal lengths. Still, the Canon offers optical image stabilization (OIS), which effectively counteracts handshake when zoomed in.

Casio, instead, employs sensor-shift stabilization, which also helps with handheld shots but typically can’t handle long telephoto shake as effectively as Canon’s OIS system.

Autofocus Performance: The Critical Detail Grabber

Focusing speed, accuracy, and tracking can make or break your shooting experience, especially when photographing moving subjects.

The Canon SX510 HS uses contrast-detection autofocus with face detection capabilities and a single focus point but includes continuous autofocus and tracking modes - meaning it can adjust focus tracking to a moving subject within reasonable speed limits.

Casio EX-Z270's autofocus system is decidedly simpler: contrast detection only, with no face or tracking AF support. Focus speed tends to be slower, with occasional hunting in low light or high contrast scenes.

For static subjects like portraits or landscapes, both cameras perform adequately. But when shooting wildlife or sports - where fast, reliable focus is paramount - the Canon’s system clearly edges ahead.

Photography Genre Suitability: How Do They Really Stack Up?

It’s helpful to think about which camera suits which photography discipline, so let’s walk through key genres and test these two in real-world suitability:

Portraits: Skin Tones and Bokeh

Portrait enthusiasts will appreciate that the Canon SX510 HS can shoot at a wide aperture of F3.4 - decent for some background separation but far from the creamy bokeh of bigger sensor mirrorless bodies.

Having face detection helps nail focus reliably on eyes, a boon for casual portraiture.

Casio’s narrower aperture (starting at F2.6 but quickly narrowing) and lack of face detection mean less control over the depth of field and focus reliability. Bokeh is minimal simply due to sensor and lens constraints.

Landscapes: Dynamic Range and Resolution

Landscape photography demands good resolution and dynamic range to capture details from shadows to highlights.

The Canon’s 12 MP CMOS sensor and Digic 4 processor deliver better dynamic range and slightly higher resolution than Casio’s 10 MP CCD sensor.

Neither camera sports weather sealing, so shooting in adverse conditions calls for caution.

Wildlife and Sports: Autofocus and Burst Rates

The Canon’s 30x zoom paired with continuous AF and a burst rate of 4 frames per second gives it reasonable capability for casual wildlife and sports shooters - though don’t expect professional grades here.

Casio lacks continuous AF and sports no burst shooting mode, making it unsuitable for fast action.

Street and Travel: Portability vs Versatility

Here’s where opinions split based on priorities. The Casio EX-Z270’s utterly tiny size and weight make it a discreet street shooter and an excellent travel companion.

The Canon SX510 HS is bulkier but offers more zoom versatility, better image quality, and more control options. It’s still pocketable, just about, but more noticeable.

Battery life favors Canon as well, rated around 250 shots per charge versus Casio’s unspecified but generally lower stamina, due to its small battery.

Macro and Night/Astro Photography

Neither is designed with specialized macro or astro imaging in mind, but the Canon’s minimum focus distance of zero centimeters (well, almost) gives it an edge for close-ups.

Night photography sees the Canon’s higher ISO ceiling of 3200 outperform Casio’s max ISO 1600, though both struggle with noise at higher settings.

Video Capabilities: Simple but Functional

Both cameras offer video recording but with notable differences:

• Canon SX510 HS records up to Full HD 1080p at 24 fps, along with 720p and VGA modes, using H.264 compression. The built-in optical IS helps stabilize footage.
• Casio EX-Z270 maxes out at 720p 24 fps with Motion JPEG format, which is less efficient and results in larger files.

Neither camera sports a microphone or headphone jack, which is no surprise given their compactness and era.

All told, Canon offers a modestly superior video experience thanks to higher resolution and better codec efficiency.

Build Quality and Weather Resistance

Neither camera offers serious weather sealing, splash proofing, or rugged durability, so users should be mindful of exposure to the elements.

Canon's SX510 HS’s more robust plastic body with textured grip feels more substantial and durable than Casio’s lightweight, shiny plastic shell, which feels fragile in hand.

Display and Viewfinder

Both cameras lack an electronic viewfinder, relying exclusively on LCD screens for composing shots.

The Canon’s LCD is a 3-inch 461k-dot TFT screen, fixed in place, offering a decent balance of resolution and size.

Casio’s smaller, lower-resolution 2.7-inch screen at 115k dots provides a more grainy preview.

Neither addresses glare well outdoors, a common weak point in compact cameras.

Connectivity and Storage: Modern Conveniences

Connectivity is primarily limited:

• Canon SX510 HS includes built-in Wi-Fi for wireless sharing and image transfer - a valuable convenience for casual social shooters.
• Casio EX-Z270 has no wireless features.

Both cameras use standard SD/SDHC/SDXC memory cards in a single slot.

Price and Value: What Are You Really Paying For?

At launch, the Canon SX510 HS retailed around $249, representing solid value for a superzoom compact with manual controls and Wi-Fi.

The Casio EX-Z270 is harder to price due to age and rarity but was initially a budget-focused ultracompact.

Given its features, image quality, and zoom range, the Canon clearly delivers more bang for your buck in today’s market - if you can handle the larger size.

Putting It All Together

When evaluating cameras like the Canon SX510 HS and Casio EX-Z270, it’s essential to remember their market positioning. The Canon is a 2013-era superzoom workhorse blending advanced controls and a versatile lens with a slightly dated sensor, while the Casio is more of a budget ultracompact for quick, easy snapshots.

If your photography aims involve more control, zoom range, or low light capability - and you don’t mind a bigger camera - the Canon is clearly the better choice. Yet if you want a near-invisible camera for casual snapshots, the Casio still holds some charm due to its minuscule size and simplicity.

In today’s fiercely competitive camera market - where smartphones have stepped up their game - these dedicated compacts face tough competition. But they still serve niches well and offer tactile shooting experiences that phones can’t match.

Whichever you pick, remember that the best camera ultimately is the one you have with you and enjoy using.

Happy shooting!
