Canon SX420 IS vs Olympus SP-800 UZ: A Deep Dive into Small-Sensor Superzoom Bridge Cameras

When selecting a superzoom bridge camera with a small sensor, it’s easy to feel overwhelmed by the sheer number of options - especially models that look strikingly similar at first glance. Today, I’m putting two notable contenders head-to-head: the Canon PowerShot SX420 IS and the Olympus SP-800 UZ. Both cameras cater to enthusiasts wanting high reach zoom lenses in an all-in-one package, but they approach key photography needs with different strengths and quirks. Having spent hands-on time testing their features and image output across diverse shooting scenarios, I’m excited to guide you through a detailed comparison.

By the end, you’ll have a clear grasp of how these cameras stack up in real-world use, and which might be the better fit for your photography style and budget.

Getting to Know the Contenders: Design, Size, and Ergonomics

Both cameras embrace the popular bridge camera form factor - offering DSLR-like handling with fixed lenses delivering very long zoom ranges. But their physical builds and ergonomics differ in subtle yet significant ways.

The Canon SX420 IS opts for a more compact and lightweight body, weighing in at just 325g and measuring 104x69x85mm. Contrast that with the bulkier Olympus SP-800 UZ, which tips the scales at 455g and measures 110x90x91mm. If portability and on-the-go comfort are high on your priority list, Canon definitely has the edge here.

Holding them side-by-side, the Canon feels nimble, especially for extended handheld shooting sessions like street or travel photography. The Olympus, by comparison, projects a more robust presence but may fatigue smaller hands faster.

Looking at the top view, the Canon’s control layout is simplified, stripping out advanced dials in favor of a more streamlined approach - which makes for approachable shooting if you’re new to superzooms or want point-and-shoot ease.

Olympus offers a more traditional compact design but with more buttons and a slightly less intuitive grip. Neither camera features an electronic viewfinder - a real downside if you prefer composing with your eye to the camera, especially under bright daylight.

In summary, Canon SX420 IS wins the ergonomics race for casual, travel-oriented shooters looking for ultra-zoom in a tidy package, while the Olympus SP-800 UZ’s larger body lends itself to the stability that longer focal lengths demand.

The Sensor Battle: How Image Quality Stacks Up

Both cameras use a 1/2.3” CCD sensor with identical dimensions of 6.17x4.55 mm, yielding an active sensor area of roughly 28.07 square millimeters. It’s the classic “small sensor” size commonly found in superzoom cameras, but it inevitably restricts certain image quality aspects like noise performance and dynamic range.

However, here’s where things vary:

• Canon SX420 IS sports a 20-megapixel resolution sensor.
• Olympus SP-800 UZ offers 14 megapixels.

While more megapixels might initially sound like a win for Canon, bear in mind that cramming more pixels into the same sensor size tends to increase noise and reduce pixel-level sharpness - especially in low light.

Testing images side-by-side, the Olympus’s lower megapixel count actually translates into slightly better high ISO performance and smoother gradations, although both cameras max out around ISO 1600-3200 with visible noise creeping in. Neither produces RAW files, limiting post-processing flexibility - a major caveat if you want the highest quality output.

Canon felt marginally better at resolving detail in bright daylight thanks to that higher resolution, but Olympus snatched back points with generally cleaner mid-tone rendering. Neither sensor can match the quality of APS-C or full-frame models, but within the small sensor superzoom realm, these are pretty typical results.

Viewing and Composing: LCD Screens and Interface

Neither camera offers an electronic viewfinder, which places all emphasis on the rear LCD for framing and reviewing shots.

Both feature a 3-inch fixed type LCD with 230k-dot resolution - rather standard and not very high-res by modern standards, which means images may appear less sharp or detailed on the screen compared to actual results.

In daily use, the Canon’s menu system felt noticeably cleaner and faster to navigate, despite lacking touchscreen capabilities. Olympus’s menu layout, on the other hand, was a bit more cluttered and less intuitive.

Absent touch control on both cameras - something increasingly common and convenient today - means you’ll have to rely on buttons for focus selection and settings changes, which is fine but not speedy.

My honest take here is, neither camera excels in this department, but Canon makes the user experience smoother. If you often shoot outdoors in bright light, both LCDs can tend toward glare which impairs visibility.

Autofocus and Zoom: Reach, Speed, and Accuracy in Real Use

This is crucial because superzoom cameras pride themselves on covering ultra-wide to extreme telephoto focal lengths.

• Canon SX420 IS boasts a 24-1008mm equivalent zoom range (42x optical zoom).
• Olympus SP-800 UZ offers 28-840mm (30x optical zoom).

Canon clearly wins the zoom race by a considerable margin, letting you capture distant wildlife or architectural details with more reach.

However, how does autofocus hold up?

Olympus uses contrast-detection autofocus across 143 focus points, which sounds promising on paper, but in practice, it struggles to lock quickly in low contrast scenes or fast action. It supports AF tracking but no face detection.

Canon employs a simpler AF system with face detection, but no AF tracking, and only a handful of selectable points.

In testing continuous AF for action photography, the Canon’s 0.5 fps burst rate (yes, half a frame per second!) felt frustratingly slow and impractical for sports or wildlife. Olympus vastly outperforms here with 10 fps continuous shooting, though its AF sustains only single-shot mode, requiring manual adjustments between frames.

So, for fast-moving subjects like sports or birds, Olympus’s higher frame rate and broader AF coverage shine despite slower AF response. Canon’s longer zoom loses ground due to sluggish shooting speed.

Image Stabilization: Is Your Long Lens Controlled?

When you zoom way out, image stabilization matters more than ever to avoid blurry shots.

• Canon implements optical image stabilization, leveraging lens-shift technology.
• Olympus opts for sensor-shift (sensor-shift stabilization).

My practical tests revealed both handled typical hand-shake well up to mid-telephoto range. At extreme zoom, Canon’s optical system had a slight edge in steadiness and responsiveness, minimizing obvious shakes. Olympus’s sensor stabilization is solid but less effective beyond moderate focal lengths.

If you plan to shoot handheld at full zoom frequently, I’d lean slightly toward Canon here.

Flash and Low Light Usage

Both cameras include built-in flashes - Canon with a range close to 5.0 meters, Olympus about 3.1 meters.

Canon offers several flash modes including slow sync, which can be handy for balancing flash with ambient light creatively - a feature absent in the Olympus system. However, neither supports external flash units, restricting lighting options.

Low light performance overall is modest for both, given small sensors and limited max apertures (Canon f/3.5-6.6; Olympus f/2.8-5.6).

Interestingly, Olympus starts at ISO 64 (vs Canon’s ISO 100), theoretically allowing for cleaner base shots in bright conditions. But ISO boost limitations and lack of RAW dampen low light flexibility.

Video Features: What Can You Capture Beyond Stills?

A quick glance at video specs shows both cameras top out at 720p HD recording at 30fps (Olympus) and 25fps (Canon) with no 4K options.

Amongst enthusiasts and pros, this is definitely a disappointment - 720p is relatively low resolution by today’s standard where even budget smartphones shoot Full HD or 4K.

Neither offers external microphone or headphone jacks, so audio options are limited, and neither supports continuous AF during video.

Canon’s video uses MPEG-4 and H.264 encoding; Olympus uses H.264. Both rely on built-in stabilization for video - Canon’s optical IS again gives a slight advantage in smoother handheld footage.

If video is a strong priority for you, neither camera excels, but again Canon just edges Olympus in quality.

Battery Life and Storage

Real-world endurance is often overlooked but critical.

Canon’s NB-11LH battery claims about 195 shots per charge, which is on the low side for a camera without power-hungry video or fast burst shooting.

Olympus lacks an official figure, but third-party reports suggest around 250-300 shots, slightly better due to less aggressive continuous shooting modes.

Storage-wise, both accept SD, SDHC, and SDXC cards, and Olympus includes a small amount of internal storage - a neat fallback if you forget your card.

Connectivity differs sharply: Canon includes built-in wireless with NFC pairing, useful for quick sharing or remote control via smartphone apps. Olympus doesn’t support wireless, only basic wired connections via USB and HDMI out.

This built-in WiFi is a big convenience edge for Canon.

Durability and Environmental Resistance

Neither camera offers weather sealing, dust, shock, crush, or freeze protection. Both are strictly indoor or fair-weather options.

If you want ruggedness for outdoor adventures, you’d have to look elsewhere.

Practical Photography Use Cases and Recommendations

Let me break down how these cameras perform across different photography types, based on field testing:
