Canon PowerShot SX120 IS vs Casio Exilim EX-Z450: A Deep Dive into Compact Camera Classics

The world of small sensor compacts in the late 2000s brimmed with a diverse range of affordable, pocketable cameras, each vying for a slice of enthusiast attention with varying degrees of manual control, zoom versatility, and feature sets. Two such models - Canon’s PowerShot SX120 IS and Casio’s Exilim EX-Z450, both released in August 2009 - appeal to users seeking modest yet competent shooters in a travel-friendly form factor. Having personally tested thousands of compacts across decades, I find these two cameras particularly interesting as they embody different philosophies beneath similar shells.

In this article, I will walk through an authoritative comparison of the SX120 IS and EX-Z450, focusing on build, sensor performance, handling, optics, and how each fares across photography disciplines from portraits to wildlife, plus video capabilities and real-world usability. Whether you’re a casual traveler needing a step up from a phone or a photography enthusiast hunting for faithfulness in a pocket camera, this hands-on evaluation will clarify which legacy gem fits your needs best.

Size, Handling, and Ergonomics: Comfort in Your Hands

Despite both being 'compact' cameras, the two models vary significantly in size and presence.

The Canon SX120 IS hovers on the larger side for compacts with physical dimensions of 111 x 71 x 45 mm and a weight of approximately 285 grams (excluding battery), lending it a more substantial, reassuring grip. The pronounced handgrip, albeit modest, aids steadiness - important for telephoto shots given its 10x zoom lens. The Canon uses AA batteries, which add some heft and give the option for easy replacements on the road, but bulk up the profile.

Meanwhile, the Casio EX-Z450 is markedly smaller and lighter at 81 x 56 x 21 mm and 128 grams, making it pocket-flashlight slim. Its diminutive size is a double-edged sword: excellent for discreet street or travel shooting, but presents challenges for steady handling and ergonomic comfort during prolonged use or using manual focus.

The Canon’s tactile buttons and modestly sized mode dial offer a more conventional layout. In contrast, Casio takes a minimalist approach with fewer controls and smaller buttons, which may frustrate photographers with bigger fingers or those seeking quick access to settings.

Design Language and Control Layout: Readiness on Top

A bird’s eye view confirms the Canon’s focus on manual operability versus Casio’s simplicity.

The SX120 IS sports a dedicated mode dial with PASM (Program, Aperture priority, Shutter priority, Manual) modes - valuable for enthusiasts who want creative control. It also includes exposure compensation and manual focus rings via the menu, though no dedicated ring on the lens.

The EX-Z450, by contrast, lacks PASM modes and offers only program automatic exposure. Its shutter speed caps at 1/1000s and aperture control is absent, restricting creative flexibility - potentially a limiting factor for more serious photographers or those wanting to experiment.

From extensive hands-on time, the Canon’s layout feels more inviting to users wishing to grow their skills, while the Casio is tailored for snapshot simplicity. Neither camera has touchscreen functionality, common for the era.

Sensor Size and Image Quality: CCD at Play

Both cameras sport small CCD sensors, but with subtle differences in resolution and dimensions.

The Canon SX120 IS uses a 1/2.5” CCD sensor with 10MP resolution, translating to 3648x2736 pixels. Its sensor area measures approximately 24.74 mm², a typical size for compacts of this vintage.

The Casio EX-Z450 slightly ups the ante with a 1/2.3” CCD sensor at 12MP (4000x3000 pixels), with a sensor area of 28.07 mm² - indicating a marginally larger sensor surface and tighter pixels.

This sensor size affects noise performance and dynamic range. Neither camera was subjected to DxOmark testing, but based on controlled lab exposures and field shooting, both cameras perform adequately in good light but struggle above ISO 400. The Canon, benefiting from the DIGIC 4 processor, delivers slightly better noise control and color fidelity overall. The Casio’s increased pixel count however delivers marginally better detail when shooting static scenes at base ISO.

Both cameras employ anti-aliasing filters to prevent moiré, which slightly softens fine detail - typical for CCD compacts of this era.

Screen and User Interface: What You See Is What You Get

A camera’s rear screen is your window to composition and review.

Both the Canon and Casio have 3-inch fixed rear LCD displays with 230k-dot resolution, standard enough in 2009. Neither offers touchscreen or articulated screens, limiting shooting angles especially for street or low shots.

The SX120 IS’s screen shows marginally warmer color tones and better contrast, improving visibility in direct sunlight. The Canon’s menu system is more comprehensive with PASM controls and manual focus assist options, whereas the Casio’s UI is simplified, designed mainly for casual users.

Live view focus confirmation works reliably on both, though manual focus is only moderately precise due to lack of focus peaking.

Lens and Zoom Capability: Telephoto versus Versatility

This pair differs significantly in optical reach and aperture range.

The PowerShot SX120 IS features a 10x optical zoom lens spanning a 36–360 mm equivalent focal length with a bright-ish max aperture range of f/2.8-4.3. This long telephoto reach is useful for wildlife, sports, and portraits, offering background compression and subject isolation potential.

The Casio EX-Z450, conversely, sports a shorter 4x zoom covering 28–112 mm equivalent, with an aperture range of f/2.6-5.8. Wider at the short end for landscapes and street, but lacking telephoto reach that the Canon boasts.

From my testing:

• The Canon’s longer zoom, paired with optical image stabilization, delivers surprisingly steady telephoto handheld shots. This is a plus for travel and wildlife photography, where a tripod is not always feasible.

• The Casio’s lens is physically smaller and lighter but doesn’t curb chromatic aberrations as well, especially towards the edges at wide apertures. It performs well at wide angles for landscapes and indoor shots.

Macro-wise, the Canon’s minimum focus distance is impressively close - down to 1 cm, enabling true close-up captures with fine detail, aided by image stabilization. The Casio, in contrast, requires 10 cm or more, limiting macro flexibility.

Autofocus and Burst Performance: Catching the Moment

Both lack sophisticated AF point arrays, relying on contrast detection AF systems with center-weighted focus. Neither offers face or eye detection.

The Canon SX120 IS autofocus is reasonably quick for its class, locking accurately in good light with minimal hunting. It falters in low contrast or dim indoor scenes.

The Casio EX-Z450’s AF is somewhat slower, especially zoomed in or low light, attributed partially to its smaller motorized lens mechanism. However, it supports a higher burst shooting rate of 10 fps at a reduced resolution, compared to Canon’s 1 fps continuous shooting. This can be handy for capturing fleeting expressions or action, margin for error large.

Neither is ideal for fast-moving subjects like sports or wildlife, but with patience, the Canon edges ahead in focus reliability.

Photography Genre Performance: Where Does Each Shine?

Portrait Photography

Accurate skin tones and pleasing bokeh are paramount here.

The Canon, with its longer lens and brighter apertures, allows decent subject-background separation in close second and telephoto range - an advantage for flattering portraits. The image stabilization aids sharpness at moderate telephoto focal lengths without excessive ISO.

The Casio’s shorter zoom and slower lens limit bokeh effect; portraits tend to be more “flat” with less subject isolation.

Neither camera offers face or eye-detection autofocus, a feature absent from compacts of this era.

Landscape Photography

Landscape demands high resolution, dynamic range, and wide-angle capability.

Casio’s wider 28mm equivalent lens is better suited for sprawling vistas and architectural interiors than Canon’s narrower 36mm.

Resolution favors Casio’s 12MP sensor, delivering slightly crisper images with more cropping latitude.

Dynamic range between the two is modest but comparable, both struggling in harsh contrast scenes with blown highlights.

Neither camera has weather sealing, making caution necessary in rough conditions.

Wildlife Photography

Canon’s substantial 10x zoom and image stabilization represent a clear edge here. The EX-Z450’s telephoto reach is simply insufficient for impactful wildlife closeups.

That said, neither camera features advanced tracking autofocus or rapid frame rates to effortlessly capture fast-moving animals.

Sports Photography

Canon’s slower burst rate and lack of continuous AF limit its competence for dynamic sports. Casio’s rapid 10 fps burst helps but focus hunting remains an issue.

Low light sports capture is a shared weakness; both max out at ISO 1600 with noticeable noise.

Street Photography

Casio’s pocket-friendly size and discreet shutter operation make it appealing for street shooters valuing subtlety.

Canon feels more noticeable in hand but manual exposure controls benefit creative shooters.

Low-light performance is limited on both; fast primes on interchangeable lens cameras still dominate here.

Macro Photography

Canon’s close minimum focus distance and optical IS enable detailed, sharp macros of flowers or insects. Casio lags with a 10 cm focusing limit.

Manual focus is clumsy on both; neither supports focus stacking or post-focus options to extend depth of field.

Night / Astro Photography

Limited by small sensors and lack of bulb mode or long exposures.

Canon’s slower max shutter speed of 1/15 s (minimum shutter exposure not optimized for bulb) restricts its utility for starscapes, while Casio offers 1/2 s but no interchangeability or manual ISO control.

High ISO noise is a barrier for low-light sessions on both.

Video Capabilities

Both shoot video in Motion JPEG. Canon maxes at VGA (640x480) 30 fps, while Casio offers HD 720p at 24 fps.

Neither offers microphone inputs, headphone jacks, or in-body stabilization dedicated for video.

Canon stabilizes somewhat via lens IS, delivering less shaky clips.

Build Quality and Weather Sealing: Reliability in the Field

Neither camera is weather-sealed, waterproof, or ruggedized - typical for their class and price point.

Canon’s plastic but firm chassis conveys better durability thanks to its heftier build. Casio feels more delicate with thin plastic panels.

Neither are freezeproof or shockproof.

Battery and Storage: Practicalities of Shooting Time

Canon runs on two AA batteries (niMH recommended for best performance). This offers convenience worldwide but adds weight and bulk. Users can swap batteries easily on extended trips.

Casio uses proprietary NP-40 lithium-ion battery, lighter and longer lasting in theory but riskier to replace on the go without spares.

Both cameras use standard SD/SDHC cards. Casio added internal storage, handy as a backup but modest in capacity.

Connectivity and Wireless Features

The Canon SX120 IS lacks wireless features entirely, reflecting its 2009 tech constraints.

The Casio EX-Z450 supports Eye-Fi wireless card compatibility for direct image transfer - forward-thinking at the time, though now largely obsolete.

Neither supports Bluetooth, Wi-Fi, NFC, or GPS.

Price and Value: What’s Your Investment?

At launch, the Canon listed for ~$249, Casio for ~$229. Both represent budget entry compacts.

Given Canon’s broader versatility and stronger feature set for creative control and telephoto reach, it offers better value for enthusiasts willing to manage increased size and weight.

Casio suits more casual snapshots prioritizing portability over creative flexibility.
