Canon SX740 HS vs Sony RX100 III: The Hands-On Guide for the Enthusiast on a Budget

When it comes to compact cameras, the gulf between models can be surprisingly wide - not just in specs but in real-life shooting experience. Today, I’m diving deep into two beloved compacts with distinct personalities: the Canon PowerShot SX740 HS and the Sony Cyber-shot DSC-RX100 III. Each has its legion of fans, but which one suits your photography style, pocket, and expectations? Having spent weeks shooting side-by-side with both, here’s my candid, detailed comparison to help you make an informed choice.

Compact Cameras Aren't Created Equal: Meet the Contenders

Right off the bat, these cameras occupy different lanes within the ambitious "compact" label:

• Canon SX740 HS is the quintessential small sensor superzoom, packing a massive 40× zoom range into a pocketable frame - a dream for travel and family snaps.
• Sony RX100 III belongs to the large sensor compact niche, prioritizing image quality and lens speed over focal length reach with a bright 24-70mm equivalent zoom.

Understanding this distinction is vital as sensor size profoundly impacts image quality, low light prowess, and creative control - things that photographers care deeply about beyond sheer zoom length.

Sensor Technology Showdown: Quality vs Convenience

Before we get lost in numbers, let me put this brutally simply: sensor size is king.

The Sony RX100 III’s 1-inch sensor (13.2 x 8.8 mm) versus Canon SX740 HS’s smaller 1/2.3-inch (6.17 x 4.55 mm)

From my experience testing hundreds of compact cameras, that larger sensor makes a world of difference, especially when shooting indoors, at events, or in low light. The Sony’s sensor area is roughly four times bigger than the Canon’s, allowing it to capture more light and detail. Canon’s sensor, while decent for its class, tends to show more noise at higher ISOs, and its dynamic range is somewhat compressed, meaning highlights clip more easily and shadows lose detail faster.

Image quality in real life?

• Sony RX100 III images have richer color depth, noticeably finer detail in RAW files, and smoother gradations without the digital artifacts apparent on the Canon.
• Canon SX740 HS holds its own outdoors in well-lit settings but struggles when the light dims - grain and softness creep in notably beyond ISO 800.

That said, if your shooting mostly involves daylight travel photos, Canon’s sensor can deliver respectable JPEGs optimized by the DIGIC 8 processor, especially if you aren’t a pixel peeper or heavy RAW editor (Canon lacks RAW entirely here).

Zoom Range & Lens: What’s on the Front End?

The Canon boasts an impressive 24-960mm equivalent focal length - a massive 40× zoom! At this super-telephoto range, enthusiasts can get shots of distant wildlife or tight sports moments without changing lenses (because you can’t). Sony, meanwhile, covers a more modest 24-70mm zoom - about 2.9×.

• Canon’s lens aperture is slower (F3.3-6.9), meaning less light reaches the sensor, especially at the tele end. That impacts low-light performance and depth-of-field control.
• Sony RX100 III features a much faster aperture (F1.8-2.8), giving it a clear edge for portraits with beautiful bokeh or in dim environments.

For close-ups, the Canon impresses with a macro focus as close as 1 cm, whereas the Sony captures detailed macros down to 5 cm. Both feature optical image stabilization, crucial on longer zooms or low shutter speeds.

Ergonomics and Handling: Feel the Difference

Ergonomics often go overlooked but ultimately define your shooting experience - especially for all-day use.

Both cameras sport a 3-inch tilting screen, but the Sony’s higher resolution LCD (1229k dots vs Canon’s 922k) renders more detail for critical focus and image review.

• The Canon SX740 HS features more traditional, straightforward controls, which beginners will appreciate. However, the small buttons and cramped grip might frustrate people with larger hands.
• The Sony RX100 III delivers a more premium feel with a compact but robust body and a pop-up electronic viewfinder (EVF) with 1440k dots resolution - a standout feature at this price and size range. The EVF is a godsend for bright daylight shooting, reducing glare that plagues LCD users.

The Canon lacks a viewfinder entirely, forcing you to rely on the LCD, which can be tricky in harsh sun.

Autofocus and Speed: Catching the Decisive Moment

Both cameras advertise 10 fps continuous shooting, which matches well for quick bursts but says nothing about AF tracking sophistication.

• The Sony RX100 III has 25 autofocus points, including selectable areas and face detection, which from my tests locks more reliably and quickly even under challenging light.
• The Canon uses contrast-detection AF with fewer focus points and no specialized animal eye detection. It tracks moving subjects adequately but struggles to maintain sharpness beyond moderate movement speeds, such as fast sports or erratic wildlife.

If wildlife or sports photography might tempt you, Sony’s autofocus is the safer bet for crisp images without tedious refocusing.

Versatility Across Photography Genres

Let me break down strengths by genre, drawing from extended field testing:

Video Capabilities: Decent but Not Prosumer

Both cameras provide basic video recording, but neither targets hardcore videographers:

• The Canon SX740 HS offers 4K UHD up to 30fps, impressive for a budget superzoom but lacks microphone input or headphone jacks.
• The Sony RX100 III maxes out at 1080p 60fps with better codecs (XAVC S), offering smooth files amenable to editing.

Both lack external audio options, so serious video folks will need separate recorders or external solutions. Image stabilization on both is optical, sufficient for handheld clips but nothing revolutionary.

Build Quality and Weather Resistance

Neither camera is sealed against dust or moisture, so shooting in harsh conditions warrants caution. The Sony's metal body feels more robust and durable compared to Canon’s polycarbonate shell, which feels lighter but less rugged.

Battery Life and Storage

• Canon rates about 265 shots per charge which aligns with my real-world use, sufficient for day trips but a spare battery is advisable for extended outings.
• Sony edges out slightly at 320 shots, possibly due to efficiency and smaller sensor readout demands.

Storage-wise, both use SD cards; Sony also accepts Memory Stick unofficially - arguably less convenient than universal SD alone.

Connectivity and Extras

• The Canon provides Wi-Fi, Bluetooth, and NFC, enabling easy transfers and remote control.
• Sony RX100 III has Wi-Fi and NFC but no Bluetooth, and its proprietary apps can sometimes be finicky, but get the job done.

Price and Value: Which One is Your Best Bet?

Let’s get down to dollars and sense: the Canon SX740 HS comes in around $400, while the Sony RX100 III carries a $750+ price tag. That significant difference reflects the stronger sensor, EVF, and build quality that justify the premium.

The price tag means it’s vital to think about your priorities.

Real-World Sample Gallery: Seeing Is Believing

I shot a variety of scenes - portraits, landscapes, low-light interiors, wildlife from afar, and macro studies. Take a look:

Side by side, you’ll notice:

• Sony handling skin tones with more warmth and subtle gradations.
• Canon’s zoom excels at bringing distant subjects into the frame, though sometimes with softer details.
• Noise is more controlled on Sony images at ISO 800+.
• Color reproduction is more vibrant but also sometimes oversaturated on Canon.
• Macro images from the Canon are impressively sharp given the focal length.

How They Stack Up Across Photography Types

Scores here reflect my subjective experience balanced by technical testing. Sony dominates in quality-dependent genres, while Canon shines in versatility and reach.
