Canon SX740 HS vs Olympus SP-820UZ

Canon SX740 HS vs Olympus SP-820UZ: A Hands-On Comparison of Two Compact Superzoom Cameras

If you’re in the market for a compact superzoom camera, chances are you’ve come across the Canon PowerShot SX740 HS and the Olympus Stylus SP-820UZ. Both pack impressive zoom ranges around 40x and aim to deliver versatility in a small package. But how do they really stack up against each other in practical, everyday shooting? After spending time testing both across multiple disciplines - from portraiture to wildlife, landscape to macro, and even video - I’m sharing a comprehensive breakdown so you can decide which suits your style and needs best.

Let’s dive in.

A Tale of Two Compacts: Size, Handling & Design Matter

When choosing a superzoom compact, ergonomics and portability often weigh as heavily as image quality.

Starting with physical dimensions and build, the Canon SX740 HS feels distinctly petite and modern at 110 x 64 x 40 mm and 299g, whereas the Olympus SP-820UZ is noticeably chunkier and heavier at 117 x 78 x 93 mm and 485g - almost 60% heavier! This weight difference is quite palpable when carrying either in hand or stowed away for travel.

The SX740’s slim profile and rounded edges favor a comfortable grip without feeling bulky. Olympus’s SP-820UZ, while solidly built, comes across as a bit clunkier. This impacts not just pocketability but also fatigue during longer shoots or hikes.

A closer look at the top control layout shows Canon packing modern conveniences like a tilting 3-inch LCD screen and intuitive dial for shutter and aperture priority modes, while Olympus sticks to a fixed, more basic 3-inch screen and fewer dedicated controls.

The Canon also benefits from the Digic 8 processor, giving smoother menu navigation and responsiveness. Olympus’s older design feels a step behind in UI fluidity.

If you prize a lightweight, pocket-friendly camera you can confidently carry all day, the Canon SX740 HS earns points here. Meanwhile, the Olympus SP-820UZ leans towards those who don’t mind added heft and prefer a more traditional button layout.

Sensor & Image Quality: What Does the Small Sensor Superzoom Trade-Off Look Like?

Both cameras stick to the small 1/2.3-inch sensor format common in superzoom compacts, so their native image quality will reflect sensor size limitations, but there are notable differences.

Despite sharing sensor dimensions, the Canon steps ahead in resolution by over 6 megapixels, which can translate into more detail capture especially useful for landscape shots or cropping. The back-illuminated design on Canon’s sensor aids low-light performance by improving light-gathering efficiency, whereas Olympus’s older CMOS sensor lacks this advantage.

However, Olympus offers a higher max ISO setting of 6400. In real-world use, though, both cameras show similar noise characteristics due to sensor size constraints - anything beyond ISO 800 introduces noticeable grain. Neither is ideal for demanding low-light portraiture or astro photography, but Canon’s Digic 8 processing slightly better suppresses noise and preserves color.

Don’t expect RAW shooting on either; both output only JPEGs, reducing flexibility for professional photographers who want post-capture raw adjustments.

In summary, the Canon SX740 HS pulls ahead with slightly sharper images and cleaner high-ISO performance, though the differences aren’t night and day considering sensor size limits.

LCD Screen and Electronic Viewfinder: Essential for Composing with Confidence

When shooting a travelogue or candid moments, your viewfinder experience shapes both speed and comfort.

Neither camera features an electronic viewfinder (EVF), which is a drawback if you’re accustomed to eye-level composition and stability. You’ll rely entirely on their LCD screens.

The Canon SX740 HS sports a 3-inch tilting LCD with 922k dots resolution - bright, crisp, and flexible for shooting at awkward angles or selfies (yes, it’s advertised as selfie-friendly). The tilt mechanism works smoothly and is a practical asset for vloggers and street photographers alike.

The Olympus SP-820UZ’s 3-inch fixed TFT LCD at 460k dots feels comparatively dull and less sharp. Lack of tilt reduces compositional freedom, especially in bright sunlight or low angles.

For both, touchscreen capability is absent, which may disappoint users who prefer tap-to-focus or menu navigation through direct screen interaction.

From my hands-on tests, the Canon’s screen outperforms for clarity and ergonomics, supporting more confident framing under various lighting and shooting conditions. Olympus lags behind in this category.

Zoom Range & Optical Performance: Extending Reach with Limits

Both cameras advertise around 40x optical zoom - Canon at 24-960mm equivalent and Olympus at 22-896mm equivalent.

While such focal length ranges sound enticing, the trade-off to tiny sensors and variable max apertures plays a strong role in image quality especially when zoomed in:

• The Canon SX740 HS lens aperture varies from f/3.3 at wide to f/6.9 at telephoto
• The Olympus SP-820UZ offers f/3.4 to f/5.7

At full zoom, Olympus’s lens is brighter, which aids somewhat in handheld shooting. But Canon’s more modern optics produce sharper images with less chromatic aberration and distortion across the zoom range, likely thanks to newer lens coatings and digital correction.

For subjects like wildlife or distant buildings, both struggle with image softness and stabilization at maximum zoom, but Canon’s optical image stabilization is a critical advantage:

• Canon uses optical stabilization, greatly improving handheld sharpness at long focal lengths.
• Olympus offers no image stabilization in the SP-820UZ, which is a glaring omission for a superzoom and complicates sharp telephoto shooting without a tripod.

In burst mode, Canon also beats Olympus handily - 10 fps vs 2 fps, essential when capturing sports or wildlife action.

This is the kind of performance difference I underscore when testing real-world use: a 40x zoom is only useful if you can hold steady and capture at a fast enough frame rate.

Autofocus System: Accuracy, Speed, and Face Detection

Autofocus (AF) can make or break your experience in spontaneous shooting scenarios.

Both cameras feature basic contrast-detection AF systems with face detection, but behave quite differently:

• Canon SX740 HS offers single, continuous, and tracking AF modes with face detection. It also includes multi-area and center spot focusing, aiding composure and focus accuracy.
• Olympus SP-820UZ has only contrast-detection AF, no continuous or tracking modes, and limited AF area selection. It does support face detection, but AF is sluggish and prone to hunting indoors or at low light.

I tested both cameras in challenging light and fast-paced scenarios. Canon’s AF locks rapidly and maintains tracking better, while Olympus requires a reassuring half-second or more to focus, sometimes missing shots.

Neither has eye detection or animal eye AF, which are now standard in many cameras but rare in budget compacts.

If capturing kids or pets in motion matters, Canon’s AF system is significantly more reliable and user-friendly.

Video Capabilities: What Can These Cameras Shoot and How?

Videographers, take note: these cameras offer basic video but with important usability differences.

Canon’s 4K video recording is a clear leader here, opening creative opportunities for detailed video and extracting 8MP stills from clips. The optical stabilization smooths handheld footage impressively well.

Olympus maxes out at 1080p, but adds slow-motion capture at reduced resolution - a nice feature for fun effects, though of limited professional use.

Neither camera supports microphone inputs or headphone monitoring, limiting sound control.

If video is part of your workflow - even casual - it’s hard to overlook Canon’s superior codec support, resolution, and stabilization. Olympus’s video functions feel dated in comparison.

Battery Life, Storage, and Connectivity

Battery performance is often overlooked, yet key on longer shoots or travel.

• Canon SX740 HS uses a rechargeable lithium-ion battery with approximately 265 shots per charge per manufacturer specs.
• Olympus SP-820UZ details are vague, but generally expect fewer shots due to older battery tech and added weight.

In my tests, Canon’s camera lasted comfortably through a full day of mixed shooting. Olympus demanded more frequent charging, especially when zoom and flash were actively used.

For storage, both utilize a single SD/SDHC/SDXC slot compatible with UHS-I cards. Canon supports faster UHS-I throughput, beneficial for 4K video and burst shooting.

Connectivity is another differentiator:

• Canon offers built-in WiFi, Bluetooth, and NFC for easy image transfer and remote control via smartphone apps.
• Olympus SP-820UZ has no wireless connectivity, requiring cables for data transfer.

In today’s connected world, Canon’s wireless features are a significant convenience, enabling instant sharing and seamless backup.

To crystallize this comparison, I’ve tested both cameras across multiple photography types. Below is a summary chart based on hands-on scoring I conducted considering technical specs, real-world effectiveness, and user experience.

Portraits: The Canon’s sharper sensor and better face detection make skin tones more natural and focus more reliable. Olympus tends to overexpose skin highlights and struggles with subtle AF.

Landscapes: Canon’s higher resolution and dynamic range edge Olympus for landscapes - image detail is crisper, though both have limited high dynamic range capture due to sensor constraints.

Wildlife: Canon’s faster burst rate, superior AF tracking, and stabilized lens greatly outperform Olympus’s slow focusing and lack of image stabilization.

Sports: Again, Canon leads with tracking AF and burst speed. Olympus’s 2 fps is too slow for decisive moments.

Street Photography: Canon’s smaller size and tilting screen offer compositional flexibility, but Olympus’s larger form factor and fixed screen make discreet shooting tougher.

Macro: Both achieve 1cm minimum focus distances, but Canon’s stabilization and more responsive AF provide a better macro shooting experience.

Night / Astro: Neither excels here due to sensor size. Canon’s higher ISO performance is modestly better, but long exposure noise remains prominent on both.

Video: Canon’s 4K and stabilization set it apart. Olympus offers slow-motion but at the expense of resolution.

Travel: Canon’s lighter weight, smaller size, wireless connectivity, and battery life make it the obvious choice.

Professional Use: Neither camera targets professionals - lack of RAW, limited manual controls on Olympus, and no external mic inputs limit serious work. Canon’s manual exposure modes and better image quality offer more creative control.

Lens Ecosystem & Expandability

Both these cameras are fixed lens models, meaning you cannot swap lenses or upgrade optics. This inherently limits versatility compared to interchangeable lens systems but contributes to their compact size and convenience.

Canon’s 24-960mm equivalent lens offers slightly better starting focal length and stabilization. Olympus’s zoom opens marginally wider at the shortest end (22mm), which is nice for landscapes or interiors but less impactful on the whole.

Because neither supports RAW or interchangeable lenses, serious enthusiasts looking for growth potential should consider mirrorless or DSLR options.

Environmental Durability and Build Quality

Neither camera claims weather sealing or ruggedness - both should be kept away from rain and dust. The Canon’s modern construction feels sturdier, with minimal body flex. Olympus’s bulk makes it less fragile but also bulkier to protect in adverse conditions.

If you want a compact tough camera for rough outdoor conditions, you’d need to look elsewhere.
