Casio EX-Z90 vs Olympus FE-5020

Casio EX-Z90 vs Olympus FE-5020: A Deep Dive Into Two 2009 Compact Cameras

When you sift through the flood of digital cameras released each year, some models stand out not for cutting-edge innovation, but for carving distinct niches in the compact camera segment. The Casio EX-Z90 and Olympus FE-5020 - both announced in mid-2009 - offer a compelling snapshot (pun intended) of what small-sensor compacts aimed to deliver at the end of the last decade. In this hands-on comparison, I put these two cameras through their paces, assessing their core design philosophies, imaging performance, and usability - especially relevant now for photographers pondering affordable vintage tools or collectors looking into compact camera history.

Let’s dismantle these siblings from a similar era but different corporate mindsets, revealing which excels under real-world conditions and why.

First Impressions: Size, Shape, and Control Handling in Everyday Use

When you pick up a compact camera for the first time, the feel in the hand is an immediate make-or-break aspect. Fortunately, both the EX-Z90 and FE-5020 come packed with modest footprints that adhere to the small sensor compact archetype, but their ergonomics distinctively diverge.

The Casio EX-Z90 measures a sleek 90 x 52 x 19 mm and weighs in at a scant 121 g, making it feather-light - perfect for slipping into any pocket. Olympus FE-5020 is marginally bulkier at 93 x 56 x 25 mm and somewhat heftier at 137 g. The extra girth of the Olympus translates into a fuller grip and arguably a more confident feel in hand for those wary of too-frail compacts.

Looking at the top-down design, the EX-Z90 favors simplicity with minimal protrusions, while Olympus opts for a rounder silhouette accommodating basic controls without crowding.

Controls on both cameras are intentionally pared back - neither supports manual exposure, and both rely on single-button simplicity for shooting modes. Casio’s EX-Z90 stands out with a more confident shutter button and mode dial integration, allowing quicker mode shifts. Olympus’ button layout is a bit sparse; often nudging users to rely on menus instead of tactile shortcuts.

As a full disclosure, in my experience, Olympus’s slightly larger chassis with that deeper grip helped during longer shooting sessions, while Casio’s ultra-portability suits ‘grab-and-go’ casual shooters best.

Sensor Technology & Image Quality: Small Sensors, Big Expectations?

Despite being 12-megapixel shooters released within weeks of each other, the EX-Z90 and FE-5020 have notable differences under the hood.

Both cameras utilize a 1/2.3-inch CCD sensor - still common in 2009 compacts. This sensor size, measuring a mere 6.17 x 4.55 mm, comes with well-known limitations: noise at high ISOs, limited dynamic range, and modest resolution ceilings. Casio pushes 4000 x 3000 pixels, Olympus rounds to 3968 x 2976 pixels - practically indistinguishable in pixel count but the lens and image processing vary significantly.

Casio integrates Canon’s Digic 4 processor (somewhat surprising given Casio’s usual in-house chipsets), which at that time was known for decent noise reduction and color accuracy. Olympus FE-5020 employs the TruePic III processor - a slightly older engine that delivers warm, contrasty images but with more aggressive noise suppression resulting in subtle detail loss.

ISO performance tops out at ISO 1600 on both, but image quality starts degrading much earlier, around ISO 400 for usable shots in good lighting.

In daylight and well-lit scenarios, both cameras produce respectable colors and contrast, with Casio’s EX-Z90 yielding a bit more natural skin tone rendering - a subtle but important metric for portrait shooters. Olympus images are slightly punchier but can clip highlights more aggressively.

Sadly, neither camera supports RAW output, a major limitation for professional or advanced users wanting post-processing non-destructive flexibility.

LCD and Viewfinder: The Eyepiece and Interface Experience

Given their compact nature, neither camera sports an electronic viewfinder - a trend ubiquitous in small-sensor compacts of their time. Instead, photographers must rely fully on LCD feedback for composition.

Both have identical-sized 2.7-inch fixed LCDs with 230k-dot resolutions, adequate for framing but lacking crispness for in-depth focus inspection. Casio’s screen appeared slightly warmer in my tests, while Olympus tended towards cooler color balance. Neither offers touchscreen input, limiting modern ease-of-use standards.

That said, Casio’s user interface felt marginally more responsive and accessible; navigating exposure compensation (when available), white balance tweaks, and scene modes was less cumbersome than the Olympus, which requires more menu diving due to fewer assigned buttons.

Lens Performance: How Do Their Optics Stack Up?

Lens versatility often defines compact usability. Casio’s EX-Z90 offers a 35–105mm equivalent zoom, a modest 3× range with apertures from f/3.1 to f/5.9 (fair at the wide end, somewhat slow tele). Olympus FE-5020 boasts a broader 24–120mm equivalent zoom (5× optical zoom), with apertures staying slightly narrower at f/3.3 to f/5.8.

This difference matters across photography styles. The Olympus’s wider 24mm-ish lens is a boon for landscapes and interiors, capturing more of a scene without backing up. Casio’s more telephoto-friendly reach suits portraits and moderate zooming.

While neither lens includes image stabilization, the Olympus’ macro mode impresses with a very close focusing distance down to 1cm (compared to 10cm for Casio), allowing more creatively framed close-ups.

Autofocus and Burst Shooting: Tracking Moving Subjects

Both cameras utilize contrast-detection autofocus with single-shot AF options only - no continuous AF or tracking. Neither can match the responsiveness or precision demanded by contemporary standards or serious action photography.

In bright conditions, AF performance is quick - around half a second lag - but in low light or low contrast scenes, hunting becomes obvious and frustrating.

Both cameras lack fast continuous shooting modes; neither offers true burst shooting, limiting their capacity for capturing fast-moving subjects such as wildlife or sports.

Battery Life and Storage: Powering Up and Memory Capacity

Battery details are sparse for both, but the Casio EX-Z90 uses the NP-60 rechargeable lithium-ion battery, while Olympus FE-5020 employs the LI-42B - both standard compact camera batteries lasting roughly 150-200 shots per charge depending on usage.

Storage-wise, Casio accepts SD/SDHC cards plus has internal memory - a bonus for emergency shooting. Olympus uses xD-Picture Card or microSD cards, which reminds us of Olympus’s then-proprietary card format legacy alongside more common microSD support.

Connectivity and Extras: Wireless Features and Flash Systems

In the connectivity department, Casio’s EX-Z90 surprisingly includes Eye-Fi card compatibility - allowing wireless image transfer when paired with an Eye-Fi wireless SD card. Olympus FE-5020 lacks any wireless features.

Flash range slightly favors Olympus (4.1 m vs 3.0 m) with similar flash modes including red-eye reduction and fill-in.

Neither supports external flash units or microphone inputs for video.

Real-World Use Case: Photography Genre Suitability

To truly understand these cameras, we have to break down their performance per genre.

Portrait Photography: Skin Tones and Bokeh

Neither camera can contest DSLRs or mirrorless cameras with larger sensors for creamy bokeh or razor-sharp eye detection autofocus.

Casio’s EX-Z90 edges ahead with slightly better skin tone reproduction, avoiding the unnatural warmth Olympus sometimes pushes. Their fixed lenses’ shallow depth of field is limited, but Casio’s slightly longer tele lens helps isolate subjects a bit better.

No face detection AF, no eye focus - so manual focus or careful framing is essential.

Landscape Photography: Dynamic Range and Resolution

Both cameras’ CCD sensors inherently limit dynamic range - a known CCD trait that manifests as clipped highlights or shadows lacking detail.

Given the 12MP resolution and 1/2.3” sensor, the Olympus’s wider lens is preferable for landscapes, letting you capture expansive scenes with less lens distortion.

Both suffer in challenging lighting; strong sunlight or dusk scenes reveal noise and blocked shadows.

Wildlife and Sports Photography: Speed and Tracking

Neither camera suits serious wildlife or sports shooters:

• Autofocus speed is adequate for still or slow-moving subjects, but not fast.
• Burst rate is effectively non-existent.
• Lens zoom range: Casio’s 3× zoom is short for wildlife telephoto needs, while Olympus’s 5× zoom is better but soft at the longest focal lengths.

Street Photography: Discretion and Low Light Capability

Compact size and light weight suit street photography. Casio’s smaller size wins here for discreet shooting; Olympus’s larger build is more noticeable.

Low-light performance is poor on both - noise escalates quickly past ISO 400 making night street scenes challenging without flash.

Macro Photography: Close Focus Detailing

Olympus FE-5020 deserves kudos with an impressive 1cm macro focus distance - fantastic for extreme close-ups with decent detail capture.

Casio EX-Z90’s 10cm macro is more typical but less specialized.

Night and Astro Photography: High ISO and Exposure Modes

High ISO noise and limited exposure control mean neither camera excels in night or astrophotography:

• ISO performance peaks at 1600 but becomes unusable beyond 400 ISO.
• No manual shutter speed or aperture control.
• No RAW saving to recover shadows.

Video Capabilities: Recording Quality and Stabilization

Video on both is rudimentary:

• Casio EX-Z90 supports 720p HD at 24fps - unusual for 2009 compacts, albeit with limited codec support (Motion JPEG). Flicker under artificial lights is visible.
• Olympus maxes at VGA 640 × 480 at 30fps, less desirable in 2024 terms.

Neither camera offers image stabilization or external mic inputs, limiting versatility for video creators.

Travel and Versatility: Battery Life and Weight

For travel photography, I’ve found Casio’s lighter weight and smaller size more user-friendly. Olympus compensates with a wider zoom lens and better macro capability but at the cost of portability.

Neither offers weather sealing, though Olympus hints at some environmental sealing - a small plus for light inclement weather exposure.

Build Quality and Durability: Which Feels More Resilient?

Neither camera targets rugged use, but Olympus FE-5020 slightly edges Casio EX-Z90 in build robustness and environmental sealing. While not waterproof or shockproof, Olympus claims environmental sealing, a minor yet meaningful reassurance against dust or moisture ingress.

Casio’s ultra-light body feels more delicate in hand, susceptible to bending under pressure despite a solid plastic build.

Software Ecosystem and Workflow Integration

A major professional or advanced user pain point is lack of RAW support and limited manual control options, seen in both models. Neither camera plugs cleanly into professional workflows requiring color grading or detailed image adjustments.

JPEG-only shooting, coupled with older image processors, restricts post-processing flexibility.

Wrapping Up: Lessons From These Vintage Compacts

While neither the Casio EX-Z90 nor Olympus FE-5020 can rival modern mirrorless or even budget DSLRs today, their value lies in representing a no-nonsense, approachable photographic experience from an era transitioning from nostalgic simplicity to nascent digital sophistication.

They remind us that sensor size fundamentally defines image quality potential more than megapixel counts or zoom ranges. Both cameras’ CCD sensors, while capable of producing decent 12MP images, cope poorly with dynamic range and low light - a key lesson for anyone evaluating small sensor compacts today.

If I could ask either to evolve with the times, it would be for raw output support, faster and continuous autofocus modes, image stabilization, and finer exposure controls - all absent here and sorely missed.
