Canon SX20 IS vs Olympus SZ-16 iHS

Canon SX20 IS vs Olympus SZ-16 iHS: A Deep Dive Into Two Small Sensor Superzooms

Choosing between the Canon PowerShot SX20 IS and the Olympus SZ-16 iHS is no straightforward task, especially when both fall into the small sensor superzoom category yet appeal to different priorities and shooting styles. Having spent countless hours testing compact and bridge cameras, I’m keen to walk you through every angle of these two models - not just their spec sheets but how they behave when you raise them to your eye, how they respond in various lighting conditions, and how well they handle the demands of different photography genres.

Let’s explore the Canon and Olympus through a seasoned enthusiast’s lens, so you come away confident about which camera suits your photographic ambitions and budget.

The Physical Feel: Ergonomics and Handling

First impressions matter, and that starts with how these cameras sit in your hand and interact with your shooting style.

Canon’s SX20 IS sports a classic bridge camera design - somewhat SLR-like in appearance and ergonomics - with a solid grip and a relatively heavy body at 600 grams. Its physical size measures 128x88x87 mm. Olympus SZ-16 iHS, meanwhile, is a more traditional compact, lighter and pocketable, weighing just 226 grams and measuring 108x70x40 mm.

I personally appreciate the heft of the SX20 IS for longer shooting sessions, especially when attached to its lengthy 28–560mm lens. The SX20 IS feels like a sturdy workhorse, with plenty of manual control dials for quick adjustments - a boon when shooting action or wildlife.

The Olympus SZ-16 iHS, by contrast, charms with its straightforward, pocketable form factor. Though it lacks a viewfinder and some manual control options, it’s eminently travel-friendly and less conspicuous for street or travel photography. Its slimmer profile makes it easier to slip into casual daily carry.

Top Controls: Mastering Exposure and Focus

Looking top-down reveals some thoughtful differences in design philosophy.

The Canon SX20 IS places emphasis on manual exposure - shutter priority, aperture priority, and full manual modes are all there, accessible via dedicated buttons and dials. This reflects Canon’s heritage of catering to users who want creative control.

Olympus drops manual exposure entirely. The SZ-16 iHS runs mostly in full auto or scene modes, more of a point-and-shoot mindset, with no dedicated knobs for ISO or shutter speed. For enthusiasts who crave deeper exposure control, the Olympus will likely frustrate.

But Olympus counters with easy scene selections and pet auto shutter for capturing furry subjects - a cute albeit niche feature. Canon’s external flash compatibility also gives it an edge in controlled lighting scenarios - Olympus forgoes this option.

Sensor Technology and Image Quality: Where Fundamentals Lie

Both models pack a 1/2.3-inch sensor - typical for bridge and compact superzooms of their generations - but their sensor technology and resolution differ substantially.

Canon’s SX20 IS uses a 12-megapixel CCD sensor, with a maximum ISO of 1600. Olympus pushes this further with a 16-megapixel CMOS sensor that extends sensitivity up to ISO 6400.

From my experience with CCD sensors, Canon tends to deliver pleasing color rendition and contrast, especially in good light. However, CCDs generally underperform at higher ISOs compared to CMOS sensors, which handle noise better.

Olympus’s CMOS sensor thus offers a more modern advantage: cleaner images at elevated ISO settings and better battery efficiency. The increased resolution means you get more detail, but also more demands on lens sharpness and image stabilization.

In side-by-side testing, Olympus produces crisper landscapes and more detailed wildlife shots, especially when cropping tight at the long end of the zoom. The downside is the slower maximum shutter speed (1/2000s vs Canon’s 1/3200s), which may marginally impact fast action freezing.

The Screens: Reviewing Your Work and Composing Shots

Neither camera has a touchscreen, which you might find limiting compared to modern standards, but their display technology takes notably different approaches.

Canon’s fully articulating 2.5-inch, 230k-dot LCD grants you considerable compositional flexibility - especially useful for low or high-angle shots. However, the resolution is modest, making preview images somewhat coarse.

Olympus offers a larger 3-inch, 460k-dot fixed screen. It’s sharper and brighter, lending itself to easier photo review and composition in bright daylight. The lack of articulation restricts angles, but the increased clarity somewhat compensates.

For live view autofocus, Canon’s articulated screen and dedicated manual focus ring combine to provide better manual focus precision in tough situations like macro or low light.

Autofocus Systems: Catching the Decisive Moment

Speed and accuracy in autofocus (AF) truly separate capable cameras from those that struggle in unpredictable environments.

Canon’s SX20 IS relies on contrast detection with 9 AF points but no face or eye detection support. It lacks continuous autofocus and tracking modes, locking focus only in single-shot.

Olympus steps up with contrast detection AF as well, but adds face detection and even rudimentary tracking, according to specifications. In real-world tests, I found Olympus’s AF more willing to lock onto faces and maintain focus on moving subjects, particularly useful for street and casual portrait shooting.

Neither model is lightning-fast compared to today’s mirrorless hybrids or DSLRs, but Olympus’s implementation feels more refined and user-friendly.

Image Stabilization: Holding Steady at Telephoto Distances

Superzooms demand effective stabilization - those long focal lengths amplify vibration, easily resulting in blurry shots.

Canon implements optical Image Stabilization (IS) in the lens assembly, while Olympus employs sensor-shift stabilization.

Optical IS generally excels at compensating for handshake during zoom-in telephoto shots, which I found Canon SX20 IS handled well, reducing camera shake effectively up to the 20x zoom reach.

Olympus’s sensor-shift stabilization offers a more general-purpose approach beneficial in macro mode and video as well. However, with the SZ-16’s narrower maximum aperture and slower shutter speed ceiling, image stabilization struggles a bit to compensate fully in dimmer lighting.

Lens Characteristics: Zoom Range and Aperture Flexibility

Lens specifications often define what you can capture - here’s where these cameras show their true differences.

Canon’s 28-560mm equivalent (a 20x zoom) spans wide-angle walk-around to strong telephoto reach with a relatively bright maximum aperture range of f/2.8-5.7. Such a fast wide aperture is a huge bonus for low light and controlling depth of field.

Olympus’s 25-600mm equivalent (24x zoom) offers a slightly wider field upfront and even longer reach at telephoto, but with a slower aperture range of f/3.0-6.9, which limits light gathering and bokeh potential.

Having personally tested both lenses, I can confirm Canon’s lens delivers richer background separation at wide apertures, making portraits with creamy bokeh more achievable. Olympus requires more light or higher ISO to compensate, which can introduce noise.

Video: Capturing Moving Moments

Both cameras provide HD video capture but with some caveats.

Canon SX20 IS records 720p at 30fps in H.264 format, but lacks microphone and headphone ports. Its video is serviceable but not designed for videographers, largely due to its sluggish continuous AF and limited video resolution.

Olympus SZ-16 iHS matches the 720p/30fps capability but supports MPEG-4 and H.264 codecs. While it also lacks external mic input, its sensor-shift image stabilization aids smoother handheld footage, a small but notable advantage.

Neither camera is suitable for pro-standard video work, but their video modes cover casual filmmaking or family moments well.

Battery and Storage: Power for the Long Haul

Sony surprises often come in unexpected packages, but here the basic numbers speak for themselves.

Canon SX20 uses 4 AA batteries - convenient if you’re traveling in areas without frequent charging options; you can buy alkalines or rechargeables widely. However, AA batteries add bulk and weight. Battery life varies widely with usage pattern; heavy use may necessitate spares.

Olympus SZ-16 iHS uses a proprietary LI-50B lithium-ion battery pack rated for approximately 220 shots, which is modest for modern expectations.

In terms of storage, Canon supports SD, SDHC, and MMC cards, while Olympus further supports SDXC. Both have a single card slot.

What the Samples Say: Quality in Practice

I’ve captured a series of test images to showcase their practical output.

Look closely and you’ll notice Canon’s images produce warmer skin tones and smoother gradients in highlights and shadows, thanks partly to the CCD sensor and Digic 4 processor. Meanwhile, Olympus images show finer detail in foliage and landscapes with less noise at ISO 400-800, attributable to its modern CMOS sensor and higher megapixel count.

In macro shots, Canon’s brighter aperture provides easier focusing in darker scenes, but Olympus’s stabilization helps achieve sharper handheld captures.

Genre-Specific Performance: Finding Your Fit

Now let’s break down each camera’s merit in popular photography genres, so you can match strengths to your interests.
