Canon PowerShot SX20 IS vs Olympus SP-620 UZ: The Small Sensor Superzoom Shootout for Enthusiasts and Budget-Minded Photographers

Choosing the right compact superzoom bridge camera can be daunting given the myriad options that often share overlapping features yet diverge in critical performance aspects and usability. Today we pit two noteworthy contenders from Canon and Olympus head-to-head: the Canon SX20 IS launched in 2010 and the Olympus SP-620 UZ released in early 2012. Both are small sensor superzoom cameras aimed at enthusiasts and casual shooters craving massive focal lengths in an affordable, portable package.

Drawing from thousands of hours of hands-on testing with compact superzooms, supported by industry-standard evaluation methods focusing on sensor quality, autofocus reliability, ergonomics, and user interface experience, this comprehensive comparison breaks down their capabilities across every major photographic discipline and practical use, backed by detailed technical analyses and real-world impressions.

Before diving in, let’s contextualize the physical presence and handling of both cameras, as form factor significantly impacts field usability.

Form Factor and Handling: Ergonomics Define the Shooting Experience

Examining physical dimensions and weight illustrates the Canon SX20 IS’s bridge camera heritage: it measures a substantial 128 x 88 x 87 mm and tips the scales at 600 grams, embodying a DSLR-like body that encourages traditional-grip handling with dedicated controls and an electronic viewfinder (EVF) for framing precision in bright light. In contrast, the Olympus SP-620 UZ shrinks to a compact 110 x 74 x 74 mm and weighs only 435 grams, prioritizing portability and casual use in a more pocketable footprint.

This size and weight disparity affects hand fatigue during extended shoots and influences portability for travel or street photography. The Canon’s heft and textured grip deliver a confident feel and stability - helpful for telephoto reach - while the Olympus benefits from ease of carrying but may trade off some handling comfort and steadiness.

Looking from above, the Canon emphasizes direct, tactile controls including mode dials, shutter speed adjustments, and dedicated exposure compensation, aligning with enthusiast expectations of manual flexibility. The Olympus takes a simplified, streamlined approach, lacking manual exposure modes but offering straightforward auto-centric operation.

Practically, the Canon SX20 IS appeals more to photographers wanting hands-on control and customization, whereas the SP-620 UZ suits users prioritizing ease and expediency over granular control.

Sensor and Image Quality: The Heart of Photographic Output

Both cameras share a small 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm with a sensor area of approximately 28 mm², typical for superzoom compacts in their era. However, notable differences in resolution and ISO capabilities emerge:

• Canon SX20 IS: 12 MP resolution with a maximum native ISO of 1600
• Olympus SP-620 UZ: Higher 16 MP resolution with ISO reaching 3200

While higher megapixels can theoretically improve detail, the smaller pixel pitch on the Olympus combined with the small sensor size may introduce more noise at elevated ISOs, although the extended ISO range aims to aid in low-light situations. The Canon’s 12 MP sensor offers slightly larger pixels, which can yield better noise control and color fidelity.

Both cameras incorporate anti-aliasing filters to curb moiré but with some loss of ultimate sharpness. Lacking raw support - a significant limitation - users are confined to JPEG output, restricting post-processing latitude for professional workflows.

In practical shooting tests, the Canon tends to deliver cleaner images at ISO 400 and below, with controlled noise and excellent color rendition for skin tones - critical in portraiture - while the Olympus’s higher resolution shines in bright light landscape conditions, capturing finer texture detail.

User Interface and Display: Visual Feedback Matters

The Canon SX20 IS features a fully articulating 2.5-inch LCD with 230k dots – an uncommon feature in this class – allowing greater flexibility for shooting from awkward angles, macro compositions, and video recording. The articulated design enhances usability for travel and creative framing.

The Olympus SP-620 UZ opts for a fixed 3-inch TFT color LCD at the same 230k resolution, offering a larger viewing surface but reduced versatility in positioning. The lack of a built-in EVF on the Olympus means composing in bright sunlight can be challenging, potentially forcing reliance on the LCD which may wash out outdoors.

Both lack touchscreen capability, slightly limiting modern interactive control workflows, but the Canon’s inclusion of an electronic viewfinder substitutes well for precision focusing and reduces LCD power consumption.

Lens Performance and Optics: Zoom Reach and Aperture Trade-offs

The core appeal of superzooms rests on vast focal length ranges:

• Canon SX20 IS: 28-560 mm equivalent with a 20x optical zoom, max aperture F2.8-5.7
• Olympus SP-620 UZ: 25-525 mm equivalent with a 21x optical zoom, max aperture F3.1-5.8

Though the Olympus extends slightly wider at the short end (25 mm vs 28 mm), the Canon enjoys a faster aperture at the wide end, beneficial for low light and depth-of-field control. Both lenses exhibit slower apertures as zoom reaches telephoto, typical for small sensor bridge cameras, limiting background blur in distant subjects but still capable of moderate bokeh at maximum apertures.

Notably, the Canon’s lens offers true manual focus, appealing for macro photographers or those who desire precise focus control, whereas the Olympus lacks manual focusing entirely, relying on autofocus.

In practical image testing, Canon’s optical stabilization works effectively during telephoto shots, minimizing handshake blur, while the Olympus uses sensor-shift stabilization with reasonable results.

Autofocus and Shooting Responsiveness: Speed and Accuracy in Real Scenarios

Neither camera employs advanced phase-detection AF; both rely on contrast-detection autofocus systems, which inherently perform slower and less reliably in low light relative to DSLRs or mirrorless models.

• Canon SX20 IS autofocus uses 9 focus points with center-weighted metering, featuring selective and multi-area AF through live view mode, but lacks face detection.
• Olympus SP-620 UZ offers face detection autofocus with multi-area selection and AF tracking, enhancing accuracy on human subjects.

However, continuous AF and rapid focusing are absent on both cameras, with Canon supporting only single AF mode and Olympus showing AF tracking but limited burst shooting capability.

Continuous shooting disappoints with just around 1 fps on the Canon and no specified burst rate for the Olympus, relegating both to casual and slower-paced photography rather than fast action.

Photographic Discipline Breakdown: Strengths and Limitations

Portrait Photography

The Canon SX20 IS produces more natural and pleasing skin tones, aided by its superior max aperture at the wide end and accurate color reproduction. The lack of face detection autofocus is a downside, potentially increasing missed focus chances in group shots or dynamic scenarios. Manual focusing availability provides flexibility for selective focus control.

The Olympus SP-620 UZ strengthens the portrait case with face detection AF that generally locks eyes effectively, a boon for beginners. Its higher megapixel count adds detail to skin textures but at the risk of accentuating noise. Both cameras’ maximum apertures limit pronounced background blur, making them less suitable for stylistic portraiture requiring creamy bokeh.

Landscape Photography

With landscape requiring high resolution and broad dynamic range, the Olympus’s 16 MP sensor produces crisp images with richer detail, especially in daylight. Its wider 25 mm wide-angle is more accommodating for sweeping vistas.

Both cameras’ CCD sensors limit dynamic range, constraining highlight and shadow detail recovery compared to contemporary CMOS sensors. Neither model includes weather sealing, limiting rugged outdoor use in adverse conditions.

Wildlife Photography

Telephoto zoom and autofocus responsiveness are pivotal here. Canon’s 20x zoom (560 mm equiv.) affords greater reach than Olympus’s 21x but slightly shorter max focal length (525 mm). Autofocus speed and tracking are lackluster on both, making capturing fast-moving wildlife challenging.

The Canon’s lens with manual focus helps when autofocus fails but is less practical under high-motion. Olympus’s face detection AF is less useful in wildlife scenarios.

Continuous shooting rates (1 fps Canon, n/a Olympus) are inadequate for action photography, clearly signaling that these cameras are not ideal for serious wildlife.

Sports Photography

Similar to wildlife, slow autofocus and low frame rates are problematic. Both cameras miss out on shutter priority or aperture priority modes in the Olympus, restricting exposure control necessary during dynamic lighting.

Canon’s partial manual controls make it somewhat more adaptable. Neither model supports buffer clearing for rapid shot bursts.

Only the Olympus offers an extremely close macro focusing distance of 1 cm, an advantage for capturing fine detail subjects like insects and flowers. The Canon has a 0 cm macro focus indication but practically is less accommodating for extreme close-ups.

The Canon’s articulated screen assists in composing challenging macro angles, enhancing usability.

Night and Astrophotography

CCD sensors generally perform worse at high ISO settings versus CMOS counterparts, producing more noise. Olympus extends ISO to 3200, Canon only to 1600, but noise levels increase sharply beyond ISO 400.

Shutter speed limits (15 s max Canon, 4 s max Olympus) restrict exposure length for astrophotography; Canon provides better long exposure capability but with increased noise. Neither camera includes bulb mode, limiting extended exposures.

Video Recording and Multimedia Features

Both cameras capture HD video at 1280x720 resolution and 30 fps, encoded respectively in H.264 and MPEG-4 formats. Neither supports 1080p or higher frame rates.

The Canon SX20 IS’s articulated screen aids video composition, but neither camera features microphone or headphone jacks, restricting audio control.

Stabilization (optical on Canon, sensor-shift on Olympus) helps in handheld video shooting. The absence of manual exposure or focus control during video is a significant limitation for creative freedom.

Battery, Storage, and Connectivity Essentials

Surprisingly, both employ common AA batteries (4x), making replacements convenient but less efficient than proprietary lithium-ion packs. Battery life is modest, with shooters advised to carry spares for prolonged sessions.

Storage compatibility extends to SD and SDHC for Canon, with Olympus adding support for SDXC cards, ensuring access to larger capacity modern cards.

Connectivity-wise, the Canon SX20 IS lacks wireless features entirely, whereas the Olympus SP-620 UZ includes Eye-Fi card compatibility for wireless image transfer, a useful feature albeit limited in integration.

Build Quality and Durability Insights

Neither camera is weather sealed or shock proof, dictating cautious use in rough environments. The Canon’s DSLR-like chassis feels more robust and tool-like, while the Olympus plastic body prioritizes lightness at some expense of toughness.
