Canon SX730 HS vs. Casio EX-Z270: An Expert's Take on Two Compact Cameras from Different Eras

In the sprawling universe of compact cameras, the choices can be dizzying - especially when you pit an accomplished small-sensor superzoom against a more modest ultracompact point-and-shoot from a previous generation. Today, we’re taking a deep dive into the Canon PowerShot SX730 HS and the Casio Exilim EX-Z270, two cameras that, on paper, couldn’t be more different in spec or intent. Yet, both have their place - and their fans.

Having personally tested thousands of cameras over the last 15 years, I’ve learned that specs never tell the full story. So, I’m bringing my experience (and a hint of well-earned skepticism) to help you understand how these two devices hold up in the trenches of real-world shooting - across portraits, landscapes, wildlife, sports, street, macro, night photography, video, travel, and professional contexts. Plus, I’ll share practical, no-nonsense advice about who should consider each camera and why.

Ready to meet the contenders? Let’s jump in.

Getting a Feel for Size, Weight, and Handling

Before pressing shutter or diving into menus, how a camera feels in your hand often makes or breaks an enjoyable experience.

Here’s where our two begin to diverge impressively:

• Canon SX730 HS: Measuring 110 x 64 x 40 mm and weighing in at 300 grams, this is a compact but confidently substantial camera. It’s typical of Canon’s small-sensor superzoom class and feels reassuringly solid - and yes, I’ve held it long enough to call it more than just pocketable: think jacket pocket or compact bag friendly.

• Casio EX-Z270: Now this one’s a nimble featherweight: just 97 x 55 x 22 mm and 111 grams, it fits snugly in a coat or jeans pocket - without weighing down your gear. Truly an ultracompact joy for when you want minimalism.

Ergonomically, the SX730 HS offers a better grip and more robust physical controls. The Casio, in contrast, is charmingly bare-bones, offering neither a viewfinder nor significant tactile controls. This matters more than you’d expect - especially if you shoot often or in demanding scenarios. The Canon’s bulk provides confidence; the Casio’s tiny frame forces you to be gentle and deliberate.

Design and Button Layout: Where Controls Meet Convenience

The SX730 HS’s top-deck is designed with the enthusiast in mind, albeit in a compact package. You get a mode dial, exposure compensation control, zoom lever wrapped around the shutter button, and a pop-up flash button - all carefully balanced.

The Casio, grippingly simple, spills out minimal controls on its top plate. The exposure compensation and shutter priority modes? Forget about those - they don’t exist here. The entire user interface is meant for the absolute casual snapper.

Personally, I found the Canon’s control layout more inviting for explorative shooting. If you like fiddling with aperture priority or manual exposure to shape your image, the SX730 HS is simply a no-brainer over the Casio. The EX-Z270’s approach will work if you want a straightforward “point and shoot” workflow - and nothing wrong with that.

Under the Hood: Sensor Size, Resolution, and Image Quality

Here’s where technology - and age - show their marks most obviously.

• Canon SX730 HS: Features a 1/2.3-inch BSI-CMOS sensor measuring 6.17 x 4.55 mm, giving an area around 28.07 mm². Resolution clocks at a respectable 20.3 megapixels (5184x3888). The modern backside-illuminated (BSI) design aids low-light sensitivity; maximum ISO is 3200, with a base ISO of 80.

• Casio EX-Z270: Has a smaller 1/2.5-inch CCD sensor (5.744 x 4.308 mm, about 24.74 mm²) bearing only 10 megapixels (3648x2736). ISO caps at a modest 1600 and starts at 100.

From my hands-on testing, the Canon’s sensor outperforms the Casio in every measurable way - dynamic range, noise control, and color depth. The SX730 HS delivers sharper images with less chroma noise at ISO 800, whereas the EX-Z270’s images start to suffer from noise and loss of detail as soon as ISO 400 is surpassed.

I ran side-by-side landscape and indoor portrait tests: The Canon’s images boast more faithful skin tones and richer tonal gradations, promising better results from cropping or post-processing.

Simply put, the SX730 HS sensor is more capable in diverse shooting conditions - anticipate cleaner files and more editing headroom.

The Tale of the Lenses: Zoom, Aperture, and Versatility

What stresses me most in compact cameras? Limited zoom ranges or slow lenses, so the Canon truly shines:

• Canon’s lens zooms from 24mm wide angle (ideal for sweeping landscapes) all the way to 960mm telephoto - that’s a massive 40x optical zoom. Aperture ranges from f/3.3 (wide angle) to f/6.9 (telephoto).

• Casio’s lens is a modest 28-112mm (4x zoom) with an aperture range of f/2.6-7.8.

In practical terms, Canon’s zoom lets you get close to distant wildlife or sports subjects without swapping lenses or hassling with teleconverters, while Casio essentially covers only walking-around focal lengths.

The Canon’s f/3.3 aperture at wide-end performs decently in low light; the Casio’s faster f/2.6 gives it a slight edge for ambient-lit close-ups, but then the narrow 4x zoom hampers composition flexibility.

Neither camera offers interchangeable lenses (fixed lens mount), so what you see is what you get. But the Canon’s lens is a dramatic leap in versatility.

Autofocus and Manual Focusing: Hunting Speed and Precision

When it comes to autofocus (AF), the Canon employs contrast-detection autofocus with face detection and continuous tracking. It features center and multi-area AF modes, giving it flexibility. The SX730 HS can shoot continuously at 5.9 fps while maintaining AF.

The Casio EX-Z270, on the other hand, has a very basic contrast-detection AF system without face detection or tracking. Continuous AF and selective AF modes are absent, and burst shooting isn't specified.

In practice, the Canon can lock focus quicker and more accurately in various lighting situations. Moving subjects are easier to track - even fleeting wildlife or kids at play. The Casio tends to hunt more and often locks focus sluggishly in lower light or higher zoom levels.

For manual focus aficionados, only the Canon offers manual focus. The Casio strictly adheres to auto-focus, limiting creative focus control.

Display, Interface, and User Experience: How You See and Interact

Both cameras lack an electronic viewfinder (EVF), which isn’t surprising for their classes, but the Canon offers a 3-inch tilting LCD at 922k dots - bright, reasonably sharp, and flexible for selfie or awkward angle shots.

The Casio sports a fixed 2.7-inch LCD with a paltry 115k dots of resolution - an outdated panel by any standard, making it harder to judge focus and exposure on the fly.

Navigating menus and settings on the Canon feels far less frustrating; you get exposure compensation, manual modes, and a logical layout inspired by Canon’s established UI. The Casio is minimal, which may please absolute beginners but frustrate enthusiasts craving more.

Real-World Photography: Use Case Deep Dive

Now, let's dissect their performance across photography genres that matter.

Portraits: Skin Tones, Bokeh, and Eye Detection

The Canon’s 20.3 MP sensor combined with its lens yields pleasing portraits with smooth skin tones and nice background separation when zoomed (or shot wide open). The face-detection autofocus is reliable enough to keep eyes tack sharp, but no eye AF (no surprise).

The Casio’s 10 MP sensor and limited lens zoom restrict portrait framing. Skin tones are flatter, and lack of face detection makes focus a guessing game sometimes.

Verdict: Canon takes this by a mile.

Landscapes: Dynamic Range, Resolution, Weather Sealing

Neither camera is weather-sealed, so DSLR-level ruggedness is off the table.

For landscapes, the Canon’s higher resolution and better dynamic range excel. Details pop, and shadow recovery is smoother.

The Casio’s tiny sensor can’t capture the same tonal range; its lower resolution limits large prints or heavy cropping.

Wildlife: Autofocus Speed, Telephoto Reach, Burst Shooting

If you enjoy wildlife, the Canon’s 40x zoom, continuous AF tracking, and near 6 fps burst frame rate make it a decent “pocket wildlife shooter.” It can capture birds from a distance well enough.

The Casio’s 4x max zoom and non-tracking AF render it unsuitable for most wildlife shots beyond stationary animals in close proximity.

Sports: Tracking, Frame Rates, Low Light Response

The Canon edges in sports shooting with AF tracking and 5.9 fps shooting, sufficient for casual sports events.

The Casio’s lack of burst mode and AF tracking make it a poor choice.

Street Photography: Discretion, Portability, Low Light

The Casio’s small size and unobtrusiveness make street shooting easy - perfect if you want to blend in (though the image quality will be limited).

The Canon is slightly bulkier, but still compact enough for street photography, with better low-light capabilities due to its sensor and stabilizer.

Macro: Magnification, Focus Precision, Stabilization

Both cameras have macro modes. The Canon focuses as close as 1 cm (super close!), while Casio lacks a specified macro focus range.

Canon’s optical image stabilization helps handheld macro shots stay sharp.

Night and Astro Photography: ISO Performance, Exposure Modes

Canon supports ISO up to 3200, offering usable images up to ISO 800 in my experience, while Casio maxes at 1600 and struggles with noise beyond 400.

Neither has specialized astro or bulb exposure modes - in fact, Canon’s 15s to 1/3200s shutter speed range is limited for long exposures, but is typical of compact cameras here.

Video Capabilities: Who Wins the Moving Pictures?

Canon SX730 HS offers Full HD 1080p @ 60 fps with H.264 encoding and AAC audio. It includes optical stabilization beneficial for smooth hand-held footage.

The Casio provides HD 720p at 24fps using Motion JPEG, an older and less efficient codec, leading to larger files and poorer quality in motion.

Neither includes microphone or headphone jacks, so external audio options are zero.

Winner? Canon by a clear margin.

Travel Friendliness: Versatility, Battery Life, and Size

Canon packs a bigger battery rated at ~250 shots per charge, which is adequate for day trips. The Casio’s battery life isn’t officially specified but generally smaller due to size.

Canon’s zoom lens versatility means fewer lenses or gear are needed on a trip. Casio’s smaller size wins ease of carry, but compromises flexibility.

Professional Use: Reliability, Formats, and Workflow

Neither camera supports RAW capture - a major drawback for professionals craving maximum post-processing control (typical in cameras of these classes).

Canon supports manual exposure modes and offers more control, edge it slightly for semi-pro or enthusiast use.

Casio feels very constrained for workflow integration.

Build Quality and Weather Resistance

Both cameras lack weather sealing or rugged protections. Canon feels better constructed with more robust plastics and mechanical buttons.

Casio’s light, thin shell is susceptible to damage if mishandled.

Connectivity: Wireless and Ports

Canon SX730 HS boasts Wi-Fi, Bluetooth, NFC, HDMI, and USB 2.0.

Casio offers HDMI and USB but no wireless.

Wireless is convenient for instant sharing or remote control - a clear advantage of the Canon.

Price and Value: What Are You Getting for Your Money?

The Canon SX730 HS retails around $399 - a reasonable choice for a superzoom compact. Its feature set and performance justify this mid-range price.

Casio EX-Z270 is discontinued, often found only secondhand or at low cost, reflecting its lower capabilities and dated tech.
