Canon PowerShot SX740 HS vs Olympus SP-620 UZ: An Expert Hands-On Comparison of Compact Superzoom Cameras

Selecting a compact superzoom camera is often a balancing act between sensor quality, zoom reach, ergonomic design, and price. Today, I’m putting head-to-head two small sensor superzoom compacts from different eras and brands: the Canon PowerShot SX740 HS (2018) and the Olympus SP-620 UZ (2012). Despite both falling into the same “small sensor superzoom” category, their technology, features, and real-world usage reflect the camera industry’s evolution over the past decade.

I’ve put both cameras through extensive side-by-side use across various photography genres - from landscapes to wildlife, street to macro. This comparison will be your one-stop guide to understanding which model works best for your specific creative goals and budget.

Let’s unpack everything you need to know to make an informed choice.

First Impressions: Size, Controls, and Handling

When evaluating superzoom compacts, handling is often overlooked but critically impacts shooting experience, especially for travel or event photography.

Compact vs Bulky - Size and Ergonomics

Physically, the Canon SX740 HS impresses with a slimmer, more pocket-friendly profile at 110 x 64 x 40 mm and weighs a light 299 grams. This makes it highly portable - ideal if you want a grab-and-go setup that doesn’t demand a camera bag.

By contrast, the Olympus SP-620 UZ is significantly chunkier, measuring roughly 110 x 74 x 74 mm and tipping the scales at 435 grams. This heft comes with a larger grip area but makes it noticeably less pocketable. For users prioritizing a lightweight carry, Canon’s offering wins hands down.

User Interface and Controls

The Canon’s DIGIC 8 processor enables playback and menu navigation to feel snappier and more responsive. It offers dedicated mode dials including aperture and shutter priority, plus manual exposure modes - essentials for photographers craving creative control.

Olympus SP-620 UZ, powered by the older TruePic III+ processor, limits users to fully automatic modes without manual exposure options. The fixed LCD screen and less ergonomic button placement reflect its age.

If you like tactile control and customizable settings, the SX740 HS clearly caters better to enthusiasts, while the SP-620 UZ is more beginner-friendly but somewhat limiting.

Sensor Insights: Imaging Technology and Image Quality

Small sensor superzoom cameras are often challenged by noise and limited dynamic range, but sensor tech innovations can make a tangible difference.

Both cameras use 1/2.3” sensors sized 6.17x4.55 mm, translating to a sensor area of ~28 mm² - standard in compact zooms but much smaller than APS-C or full frame sensors.

Canon SX740 HS Sensor

• Type: Backside-Illuminated CMOS (BSI-CMOS)
• Resolution: 20.3 megapixels
• ISO Range: 100-3200 native
• Raw Support: No
• Anti-alias Filter: Yes

The Canon’s BSI-CMOS sensor architecture optimizes light gathering efficiency, improving noise control and image quality in low light. The 21 MP resolution delivers ample detail for prints and cropping flexibility.

In my tests, the SX740 HS images exhibited cleaner shadows and richer colors with better skin tone rendition in portraits compared to older models. While still prone to noise above ISO 1600, its noise reduction algorithms balanced detail retention well without over-smoothing.

Olympus SP-620 UZ Sensor

• Type: CCD
• Resolution: 16 megapixels
• ISO Range: 100-3200 native
• Raw Support: No
• Anti-alias Filter: Yes

The Olympus’s older CCD sensor yields adequate sharpness under good lighting but struggles with noise and dynamic range at higher ISOs. Images feel flatter with less vibrant color fidelity and evident graininess creeping in beyond ISO 400. Particularly in shadows, detail loss is noticeable.

Real-World Image Quality Takeaway:

• For casual snapshots in daylight, both cameras suffice.
• For portraits demanding accurate skin tones and cleaner background rendering, Canon’s newer sensor clearly outperforms.
• Low-light and night shooting strongly favor the Canon SX740 HS.

Lens and Zoom Performance: Range, Clarity, and Versatility

Superzoom cameras’ defining feature is their focal length reach combined with reasonably fast apertures across that range.

Zoom Reach and Flexibility

The SX740 HS’s staggering 40x optical zoom translates to 24-960mm in full-frame terms - excellent for wildlife, sports, or distant architectural details. I personally tested this zoom length on wildlife subjects and was impressed by the reach without significant loss in sharpness if shooting in good light.

The Olympus offers a narrower 21x zoom (25-525mm equiv), which is still respectable for everyday telephoto shooting but less versatile. Its advantage lies in a slightly larger maximum aperture at the telephoto end (f/5.8 vs f/6.9), allowing marginally better low-light telephoto captures.

Macro and Close-Up Ability

Both cameras impressively focus down to one centimeter, great for casual macro photography such as flowers or small objects, although be advised that the depth of field becomes razor-thin. The Canon’s longer zoom range doesn’t hinder close-up focus, which is convenient.

Image Stabilization

The Canon uses optical image stabilization built into the lens, which is highly effective at countering handshake, especially at extreme telephoto focal lengths.

Olympus applies sensor-shift stabilization. While useful, it tends to show limits at very long zooms. Subjects may still appear shaky at high focal lengths without tripod assistance.

Autofocus and Speed: Tracking Subjects in Real Life

Autofocus specs can seem dry, but in practice, accurate and swift AF makes or breaks fast shooting scenarios.

The Canon features a modern contrast detection AF system with face detection and tracking capable of continuous autofocus during bursts, ideal for wildlife and sports subjects. The 10 frames per second (fps) continuous shooting ability matches entry-level DSLRs and mirrorless cameras, impressively fast for a compact.

Olympus’s autofocus system is more basic, lacking continuous AF during burst shooting and manual focus capability, limiting control over critical focus. Its shutter speed tops out at 1/1500 sec, less accommodating for very fast action.

In wildlife and sports shooting tests, I found the Canon SX740 HS notably snappier at locking focus and tracking moving subjects, while the Olympus sometimes wavered, especially in low contrast or low light.

Screen, Viewfinder, and Interface: Framing and Reviewing Images

Both cameras rely entirely on LCD screens for composing and reviewing shots - no built-in viewfinders.

The Canon’s 3.0-inch, 922k-dot tilting LCD brings versatility for shooting from high or low angles, a real plus for creative composition. While not touch-enabled, the screen remained bright and legible even in strong daylight. The lack of an electronic viewfinder is a compromise but typical for this class.

The Olympus’s fixed 3.0-inch TFT LCD screen delivers a much lower resolution 230k dots, reducing clarity in playback and making it harder to evaluate focus and fine detail out in the field. Unfortunately, it’s fixed, limiting shooting flexibility.

If you prioritize composing in bright sun or prefer angle adjustments, Canon’s screen clearly wins.

Build Quality and Weather Resistance: Durability Factor

Both cameras are lightweight compacts with plastic construction and no environmental sealing. Neither offers dustproof, shockproof, waterproof, or freezeproof certifications.

While the SX740 HS feels more solidly built and refined, the Olympus’s bulk gives an impression of robustness but with added weight penalties.

For serious outdoor or adverse weather shooting, neither camera is ideal. I’d recommend weather-resistant mirrorless or DSLR models in such cases.

Video Performance: Moving Images on the Fly

Video recording shows one of the most striking leaps forward in the Canon model. The Canon SX740 HS shoots up to 4K UHD at 30fps, a boon for travel or event videographers needing high-res 4K footage in a superzoom body.

The Olympus lagged far behind with only 720p HD at 30fps - fine for casual clips but not appealing for anyone demanding modern video quality. Both cameras lack external microphone inputs, limiting audio quality options.

I tested handheld video shooting outdoors and appreciated the Canon’s optical stabilization reducing shake, while the Olympus’s sensor-shift stabilization was less effective in video mode.

Battery Life and Connectivity: Staying Powered and Connected

Battery endurance and ease of file transfer are critical in today’s connected workflow.

• Canon SX740 HS: uses proprietary rechargeable lithium-ion battery rated for about 265 shots per charge. It supports built-in Wi-Fi and Bluetooth plus NFC for instant file sharing to smartphones - perfect for social sharing or remote camera control.

• Olympus SP-620 UZ: runs on 4 AA batteries (alkaline or NiMH). Battery life varies greatly but typically fewer shots than modern lithium-ion packs. It supports Eye-Fi card Wi-Fi connectivity (via memory card), an older tech that requires specialized cards and setup.

The Canon’s integrated wireless features and longer battery life offer significant convenience over the Olympus, especially on longer trips when charging opportunities may be limited.
