Casio EX-ZR300 vs. Olympus Stylus 550WP: A Detailed Comparison for Enthusiasts and Professionals

When selecting a compact digital camera, photographers often navigate a landscape of seemingly similar specs with vastly different real-world implications. The Casio EX-ZR300 and the Olympus Stylus 550WP - two small sensor compacts released in the early 2010s - offer interesting points of contrast. While neither is recent or designed to rival mirrorless or DSLR systems, thoroughly testing these cameras reveals lessons on sensor technology, ergonomics, and photographic versatility that remain relevant.

Having spent hours testing hundreds of compacts and small sensor superzooms across all photography disciplines, I’m excited to share my firsthand insights into how these two models stack up for various use cases - from landscapes to wildlife to video work. Beyond mere specs, this review highlights my hands-on experience assessing image quality, autofocus responsiveness, and handling to give you a genuine, practical guide. Let’s dive in.

Physical Design and Ergonomics: Big Differences in Compact Bodies

At first glance, the Casio EX-ZR300 appears more substantial - its body measuring 105 x 59 x 29 mm and weighing 205 grams - while the Olympus 550WP is smaller and lighter at 94 x 62 x 22 mm and 167 grams. This difference may seem trivial, but in prolonged shooting situations, it greatly affects comfort and stability.

The Casio’s larger frame accommodates a more pronounced grip area, which I found beneficial during extended hand-held landscape shoots or burst exposures in wildlife photography. Its fixed lens extends appreciably in telephoto reach, necessitating steadier handling. The Olympus, on the other hand, is markedly pocketable, embodying true compactness, ideal for street photography or travel scenarios where discretion and minimal bulk matter.

Control layout reviews from my hands-on sessions show the Casio features a thoughtful top and rear button arrangement with dedicated dial controls for shutter and aperture priority modes. Olympus leans towards simplicity - fewer physical controls, more automation - which fits casual use but limits professional manual exposure adjustments.

The Casio’s buttons feel tactile and responsive; however, its lack of a swivel or articulating screen is a missed opportunity for creative angles, especially low-to-the-ground macros. The Olympus offers a fixed 2.5-inch screen with modest resolution, less crisp than Casio’s 3-inch Super Clear TFT LCD, limiting preview fidelity.

Overall, if ergonomics and manual control accessibility impact your workflow, the EX-ZR300 clearly has the edge. But for those prioritizing pocket-friendliness and quick snapshots, the Olympus remains appealing.

Sensor Technology and Image Quality: The Heart of the Matter

Looking deeper, both cameras share the common compact sensor size of 1/2.3 inch, but their sensor types and megapixel counts differ sharply - a divergence with major practical repercussions.

Casio EX-ZR300 Sensor Details

• Sensor: BSI-CMOS
• Resolution: 16 MP (4608 x 3456 pixels)
• ISO Range: 80–3200
• Antialias Filter: Yes

Olympus Stylus 550WP Sensor Details

• Sensor: CCD
• Resolution: 10 MP (3648 x 2736 pixels)
• ISO Range: 64–1600
• Antialias Filter: Yes

The Casio sports a backside-illuminated CMOS sensor - a modern approach that improves light sensitivity and noise performance over traditional CCDs like the Olympus’s sensor. In extensive testing, this difference manifests most strongly in low-light and high-ISO scenarios. I captured test sequences shooting ISO 800 and above under dusk conditions, and the Casio files showed notably cleaner shadows, reduced chroma noise, and better detail retention.

In landscape shoots requiring wide dynamic range, the Casio slightly outperformed the Olympus by capturing richer shadow information and handling bright highlights with more grace - a reflection of the CMOS sensor’s superior bit-depth and readout efficiencies. However, the Olympus sensor’s 10 megapixels paired with lower resolution screens rendered images that appear softer but often more “film-like,” appreciated by some portrait photographers valuing gentle gradations.

Both cameras incorporate anti-aliasing filters, so sharpness edges are comparable when stopped down, but the Casio’s higher native resolution gives the advantage in cropping flexibility or producing large prints.

In sum, if absolute image quality - especially in challenging lighting - is your priority, the Casio EX-ZR300’s sensor technology is the more future-proof choice.

Autofocus and Exposure Controls: Precision vs. Simplicity

Autofocus (AF) is a critical aspect of any camera’s usability. The Casio EX-ZR300 features a hybrid contrast-detection system with multi-area AF, face detection, and tracking capabilities - though it lacks phase detection or eye/animal tracking technologies we expect in modern models. It also supports manual focusing, a boon for macro and creative control.

The Olympus Stylus 550WP relies exclusively on contrast-detection AF with a single center AF point and lacks face tracking or continuous autofocus modes. Manual focus is also unavailable.

When photographing wildlife or sports under variable light, I found the Casio’s AF more reliable and faster in locking focus, reducing missed shots during rapid action bursts. The EX-ZR300’s burst shooting capabilities are limited but still more flexible than the Olympus, which offers virtually none.

Exposure-wise, Casio wins hands down with shutter priority, aperture priority, and full manual exposure modes - a rare feature set among compacts of its era. Olympus defaults mostly to program mode with fewer compensations or bracketing options.

This level of manual control on the Casio complements the enthusiast photographer’s need for nuanced exposure decisions, especially in portraiture where skin tone rendition demands careful aperture selection, or landscape where exposure bracketing might capture a wider dynamic range.

Optical Versatility and Macro: Telephoto Reach vs. Close-Up Prowess

The lens focal ranges tell a big story:

• Casio EX-ZR300: 24-300 mm equivalent (12.5x zoom), F3.0-5.9
• Olympus Stylus 550WP: 38-114 mm equivalent (3x zoom), F3.5-5.0

The Casio’s superzoom lens is undoubtedly the more versatile tool - great for travel and wildlife photography, where reaching distant subjects matters. I managed to photograph birds in local parks and details in architecture without swapping lenses or changing position. Although image quality softens somewhat at the long end, the built-in sensor-shift stabilization helps maintain image sharpness.

Conversely, the Olympus’s shorter zoom range constrains framing options but benefits street photographers who prioritize quicker, less conspicuous shooting without lens extension.

Both cameras excel in macro photography differently. The Casio’s incredible 1 cm minimum focus distance lets you capture extreme close-ups of flora or small objects, an advantage that some macro photographers craving detail will appreciate. The Olympus offers a 7 cm close-focus distance, still adequate for most casual macro needs but without the same dramatic magnification ability.

Performance in Photography Genres - Which Excels Where?

Having extensively photographed with these cameras across disciplines, here’s how each fares in core genres:

Portrait Photography

The Casio’s wider lens, broader manual control, and superior sensor deliver noticeably better skin tone accuracy and subject isolation via decent bokeh at 24 mm focal length (when shooting at full aperture). Its face detection and focus tracking improve keeping subjects sharp. The Olympus’s lack of face detection and lower resolution sensor make it less reliable for consistent portraits.

Landscape Photography

Dynamic range and resolution matter here. Casio’s CMOS sensor shines, capturing greater tonal range and allowing the creation of large prints without losing fine detail. Olympus’s environmental sealing adds durability in unpredictable outdoor conditions - a plus for rugged landscape shooters. However, Olympus’s narrower zoom limits composition flexibility.

Wildlife Photography

Casio’s long zoom (300 mm equivalent) and better autofocus responsiveness provide clear advantages. Burst shooting rates are slow by modern standards but surpass Olympus’s negligible continuous shooting capabilities. Due to the Olympus’s shorter zoom and slower AF, I found it frustrating to capture decisive wildlife moments.

Sports Photography

Neither camera is truly suited, but the Casio’s wider ISO range and faster shutter speeds offer a slight edge for indoor or low-light sports shooting. Olympus’s slower shutter ceiling (1/1000s) and lower ISO max (1600) constrain its performance here.

Street Photography

Olympus’s smaller, lighter body and muted zoom extension make it great for candid street shooting, blending in unobtrusively. Casio’s larger size and lens extension can draw attention. However, Casio’s superior low-light ISO capabilities help in dim urban environments.

Macro Photography

Casio’s extreme close focusing distance (1 cm) beats Olympus comfortably. Paired with stabilization, macro shooters will find more creative opportunities on the EX-ZR300.

Night and Astro Photography

With Casio’s superior high ISO and longer shutter speeds (up to 15 seconds), night and astrophotographers get more flexibility for capturing starscapes and night scenes. Olympus’s maximum 4-second shutter limits exposure lengths, and digital stabilization cannot substitute for sensor sensitivity.

Video Capabilities

The Casio shoots Full HD 1080p at 30fps, also providing high-frame rates up to 1000 fps for slow-motion effects - a feature unique and fun to experiment with. Olympus maxes out at VGA 640x480 resolution, which feels obsolete today. Casio’s HDMI output and Eye-Fi wireless connectivity enhance workflow, enabling easier on-the-go video sharing.

Build Quality, Weather Sealing, and Durability

While neither camera is fully ruggedized, the Olympus Stylus 550WP touts water-resistant sealing, a rarity in its class. This feature makes it attractive for beach or outdoor activities with some exposure to elements.

Casio EX-ZR300 lacks environmental sealing but compensates with solid build quality. Its sensor-shift stabilization and lens construction are commendable given the price range.

If durability in adverse conditions ranks high on your priority list, Olympus holds an advantage - though at the cost of performance and sensor technology.

Connectivity, Storage, and Battery Life

Connectivity-wise, the Casio features Eye-Fi card support, offering reliable wireless image transfer workflows - a highly practical feature for event photographers or travelers wanting rapid sharing. It also supports HDMI output for external display. Olympus offers no wireless features and lacks HDMI, limiting connection options.

The Casio uses SD/SDHC/SDXC cards - the industry standard - while the Olympus employs xD-Picture Card and microSD, the former being a fading proprietary format with less prevalent availability. This might constrain long-term expandability.

Battery life rankings favor Casio as well - it offers approximately 500 shots per charge, comparatively longer than Olympus (no official rating, but generally lower due to smaller body capacity).

Value Assessment: Pricing and Overall Recommendations

At launch, Casio EX-ZR300 retailed around $329 and Olympus Stylus 550WP near $399. Given both are older models, prices fluctuate on second-hand markets, but the value hierarchies remain instructive.
