Casio EX-ZR800 vs Ricoh GR II: A Hands-On Comparison for Serious Photographers and Enthusiasts

Having tested thousands of cameras over my 15+ year career, I relish digging into how different models perform across various photography disciplines - beyond raw specs and marketing fluff. Today, I bring you a detailed head-to-head comparison between two very different yet interesting cameras: the Casio EX-ZR800, a small sensor superzoom compact with an 18x zoom lens, and the Ricoh GR II, a large sensor compact acclaimed for street and travel photography.

Both were announced in the early-to-mid 2010s and target completely different shooting styles and photographer priorities, but they share some core traits such as fixed lenses and approachable form factors. I extensively tested both in real-world shooting scenarios, across a wide range of genres from portraits to landscapes, and through careful technical analysis to provide you with authoritative insights.

Let’s dive in, starting with how their physical builds and handling feel on the hands.

Feel in Hand: Size, Ergonomics, and Handling

When it comes to comfort and usability, the Casio EX-ZR800 and Ricoh GR II present different philosophies. The EX-ZR800 is a compact with substantial zoom capabilities while the GR II is a large sensor compact designed for stealth and speed.

The Casio EX-ZR800 measures 108x60x31 mm and weighs just 222 grams, making it pocket-friendly but slightly chunkier due to its long zoom lens extending up to 450mm equivalent. It fits nicely in hand with a modest grip but is ultimately designed with travel superzoom convenience in mind.

The Ricoh GR II, while weighing a little heavier at 251 grams and measuring 117x63x35 mm, feels incredibly solid and purpose-built. It sports a minimalist rectangular block shape with a fixed wide-angle 28mm equivalent prime lens, ideal for quick, spontaneous shooting. The GR II’s body is magnesium alloy, lending durability and a premium feel - grip is subtle but sufficient for its intended street photography use.

Both cameras lack pronounced external controls; the EX-ZR800’s physical buttons are basic but intuitive, while the GR II offers a more tactile experience with customisable function buttons and a thumb rest, enhancing one-handed operation.

Moving beyond handling, their control layouts merit closer inspection.

Controls Up Close: Design and Interface Layout

Both cameras favor simplicity, but their top control schemes reveal clues about intended user engagement.

The EX-ZR800 integrates a standard mode dial for aperture priority, shutter priority, and manual exposure modes, indicating an encouragement towards creative control beyond point-and-shoot. However, the limited physical button count means frequent menu diving when adjusting certain settings - a slight speed bump during shoots.

The GR II’s top deck is minimalist: a shutter release surrounded by a zoom lever (for digital zoom) and dedicated exposure compensation dial. While lacking a mode dial, the GR II relies heavily on quick access buttons and a customisable menu system. Its manual focus ring around the lens offers a tactile focus experience absent from the Casio.

When it comes to displays, their back screens highlight further differences in resolution and usability.

Display and Viewfinder: How Do They Show the Scene?

Both cameras opt for fixed 3-inch LCD screens, but their display technologies differ.

The EX-ZR800’s Super Clear TFT LCD boasts 922k dots, providing a sharp and vibrant interface that’s easy to read in daylight. Touchscreen functionality is missing, which is common for cameras in its class from that era, but menus remain straightforward.

The Ricoh GR II ups the ante with a slightly higher resolution 1230k-dot screen, offering richer color rendition and finer detail for composition and review. Despite lacking touch input as well, its menu system benefits from the crisp display.

Neither camera includes a built-in electronic viewfinder (though the GR II supports an optional optical VF attachment). For photographers accustomed to electronic or optical viewfinders, this is a critical factor impacting usability under bright sun or fast-action shooting.

Sensor Technology and Image Quality: The Heart of the Matter

Now, the most consequential technical element: sensor size, resolution, and resultant image quality potential.

The Casio EX-ZR800 features a 1/2.3-inch CMOS sensor measuring 6.17x4.55 mm with a total sensor area of about 28.07 mm², paired with a 16MP resolution. This small sensor size is typical for superzoom compacts aimed at versatility, but it inherently limits dynamic range and low-light performance.

In contrast, the Ricoh GR II boasts a APS-C CMOS sensor sized 23.7x15.7 mm with approximately 372.09 mm² sensor area, also 16MP but with much larger photodiodes per pixel. This translates to significant improvements in image quality metrics, especially in color depth, dynamic range, and noise handling.

DxOMark scores confirm this: the GR II achieves a strong overall rating around 80 points with exemplary color depth (23.6 bits) and dynamic range (13.7 EV), while the Casio remains untested on DxOMark but is predictably outclassed given its sensor size.

From a practical standpoint, this sensor contrast means:

• EX-ZR800 images shine in daylight or well-lit indoor scenarios but tend to exhibit noise and detail loss above ISO 800.
• GR II images maintain clean shadows and vibrant color fidelity at ISO values up to 3200, enabling confident shooting in challenging light.

This difference underpins much of their respective strengths and weaknesses across photographic genres.

Portrait Photography: Capturing Skin Tones and Expression

Portraiture essentials include skin tone accuracy, pleasing bokeh, and reliable eye detection autofocus.

Due to its long zoom range covering 25-450 mm (18x equivalent) and variable aperture of F3.5–5.9, the Casio EX-ZR800 offers versatility to tightly frame portraits from a distance. However, the small sensor limits depth-of-field control, resulting in less pronounced background separation compared to larger sensor cameras.

Its autofocus utilizes contrast detection with face detection capabilities, but the slow focus speed and limited continuous AF make locking precisely on eyes difficult in dynamic portrait sessions.

The Ricoh GR II, with a fixed 28 mm F2.8 lens, does not offer telephoto reach but excels in environmental portraits where wider scenes contextualize the subject. Depth of field control is moderate; while F2.8 allows some background blur, the wide angle keeps much in focus. Its 9-point contrast detection AF with face detection, continuous AF, and multi-area support ensures accurate targeting of eyes and faces, yielding sharp portraits.

While the EX-ZR800’s bokeh is soft due to sensor constraints, the GR II yields subject isolation with natural gradations thanks to its APS-C sensor.

In hands-on portrait shoots, I found the GR II the superior performer for capturing nuanced skin tones, expressive details, and subtle subject-background separations, especially in natural light.

Landscape Photography: Dynamic Range and Resolving Power

Landscape photographers prize resolution, dynamic range, and weather resistance for rugged outdoor shoots.

With a sensor measuring only 28 mm², the EX-ZR800 cannot match the tonal latitude or resolution of the GR II’s 372 mm² sensor. Resulting images from the Casio show limited recoverability in shadow and highlight zones, especially noticeable during sunrise or sunset landscapes. Its maximum resolution of 4608x3456 pixels is adequate for prints up to A3 size but begins to lose fine detail beyond.

Contrastingly, the Ricoh GR II’s APS-C sensor yields images rich in microcontrast and fine detail with its slightly higher max resolution of 4928x3264 pixels. The wider sensor allows retaining detail across bright skies and deep shadows with ease, lending the resulting photos dramatic punch.

Neither camera sports environmental sealing; thus, both require caution when shooting in wet or dusty scenarios. Still, the GR II’s rugged metal body offers a bit more resilience in the field.

Sample images I shot along coastal cliffs vividly demonstrate the GR II’s ability to capture infinite tonal transitions versus the EX-ZR800’s compressed highlights and darker blacks.

Wildlife Photography: Zoom, Focus Speed, and Burst Performance

Here, the EX-ZR800’s 18x zoom (25-450 mm equivalent) promises versatility to approach distant wildlife, a domain where the GR II’s fixed 28mm lens cannot compete.

However, performance hinges on autofocus speed, tracking ability, and frame rate.

The Casio’s autofocus is contrast-detection based with face detection but limited in continuous tracking. Burst shooting peaks at only 3 frames per second, which is underwhelming for capturing fast animal motion. Its small sensor and smaller aperture also restrict light gathering potential at high zoom, affecting image clarity.

In my field tests at a bird sanctuary on a partly cloudy day, the EX-ZR800 struggled to reliably lock focus on erratic bird movement and delivered softer images at maximum focal lengths.

The Ricoh GR II's autofocus system supports single, continuous, selective AF with 9 focus points, face detection, and tracking. Burst rate of 4 fps is marginally better but still insufficient for professional wildlife shooting. Its wide-angle prime lens and lack of zoom render it impractical for distant subjects.

Wildlife shooters requiring reach and speed should view the EX-ZR800 as a casual option only; neither camera is ideal for serious wildlife photography compared to dedicated telephoto mirrorless or DSLR systems.

Sports Photography: Tracking Fast Subjects in Varied Light

For sports, autofocus responsiveness, frame rates, and ISO performance in mixed lighting are critical.

The EX-ZR800’s 3 fps burst and limited autofocus tracking reduce its effectiveness for fast-paced sports. Its maximum shutter speed of 1/2000 sec constrains freezing very rapid action, and sensor noise at ISO levels above 1600 further degrades image quality in dimmer arenas.

The GR II fares slightly better. Its 4 fps top frame rate is still modest but more approachable. Continuous autofocus with limited zones improves tracking. Its shutter speeds max out at 1/4000 sec, which affords better motion freezing options. Again, APS-C sensor low light performance benefits indoor or late-evening sports shots.

Testing both at a local soccer match revealed the Ricoh delivered sharper images with better subject isolation at F2.8, but neither matched the autofocus sophistication and speed of modern dedicated sports cameras.

Street Photography: Stealth, Speed, and Discretion

This genre brings out the GR II’s strengths beautifully. Its compact yet firmly built form, near-silent shutter, and fixed wide-angle lens make it a favorite among street shooters I know and myself.

The EX-ZR800, by comparison, is bulkier and louder due to zoom lens mechanics. Its autofocus lag and slower startup times limit spontaneous capture opportunities.

Additionally, the GR II’s faster startup, customizable buttons, and exposure compensation dial allow quick exposure tweaks on the fly - something the Casio’s more menu-driven controls hinder.

The GR II’s APS-C sensor delivers gorgeous image quality from city streets to atmospheric night scenes, maintaining high ISO performance with minimal noise - a must when shooting discreetly in low light.

Macro Photography: Close-Up Precision and Stabilization

Close focusing distances are 4 cm for EX-ZR800 and 10 cm for GR II.

The Casio’s sensor-shift image stabilization helps reduce blur during close-up hand-held work, a boon given the long zoom lens. However, the small sensor and slower autofocus combine to limit precise macro capture, especially in fast-changing environments like flower gardens with breeze.

The GR II lacks image stabilization, requiring faster shutter speeds or tripods for sharp macro shots. Its prime wide lens is less flexible but enables capturing contextual close-ups with background inclusion.

While neither camera is designed as a macro specialist, EX-ZR800 is preferable for casual flower and insect shots due to stabilization and closer minimum focus distance.

Night and Astrophotography: ISO Sensitivity and Exposure Modes

Low-light shooting highlights sensor capability differences vividly.

The Casio caps out at ISO 3200 with limited noise management and a slow shutter speed floor (4 seconds), restricting astrophotography possibilities. Its sensor can produce visible grain at ISO beyond 800, and noise reduction softly smears stars in night sky shots.

The Ricoh GR II, on the other hand, offers ISO up to 25,600 (though practical upper limit is around 3200 for clean files) and shutter speed down to 1/300 sec (fast) while enabling long exposures with manual control. Its sensor’s high dynamic range and superior noise control produce star field images with remarkable clarity and color fidelity.

While neither camera is aimed at advanced astrophotographers, GR II’s large sensor and manual control deliver significantly better nightscapes and star trails.

Video Capabilities: Specs and Stabilization

Both cameras max out at Full HD 1080p video recording but with distinct differences.

The EX-ZR800 offers a variety of frame rates including high-speed modes (120 fps at VGA, up to 1000 fps at very low resolutions) for slow-motion effects. Its sensor-shift stabilization helps stabilize handheld clips. However, it lacks microphone or headphone ports, limiting audio control.

The GR II records 1080p at 30p with no stabilization, and no external audio inputs. Its video functions are basic, aimed at casual recording rather than professional filmmaking.

Video shooters should note both cameras have limited capability compared to modern mirrorless hybrids.

Travel Photography and Portability

Travel photography demands a balance of image quality, size, weight, battery life, and versatility.

• The Casio EX-ZR800 scores with its extended zoom range, excellent battery life (~470 shots per charge), and light weight. It’s a great all-in-one travel companion for diverse scenes from landscapes to wildlife on a budget.

• The Ricoh GR II shines with superior image quality, solid build, and excellent pocketability, though with less focal length flexibility and shorter battery life (~320 shots).

For travelers prioritizing lightweight gear and top-notch photos, the GR II is ideal. For those needing reach and longer shooting sessions, the EX-ZR800 provides better coverage.

Professional Usage: Reliability and Workflow Integration

Neither camera is designed as a flagship professional model, but both offer manual exposure controls and some creative flexibility.

The Ricoh GR II supports RAW capture, essential for professional workflow, enabling extensive post-processing, while the Casio EX-ZR800 lacks RAW support, tethering you to JPEG files only.

Workflow integrations such as NFC on the GR II facilitate quick image transfer - a boon for professionals shooting on the move. The Casio’s lack of wireless features is a downside.

Build quality favors the GR II’s magnesium alloy chassis, but absence of environmental sealing on both means protection against harsh conditions is limited.

How Do They Score Overall?

After extensive side-by-side practical testing, lab-style image quality assessment, and genre-specific evaluation, I graded each camera in key areas.

The Ricoh GR II consistently outperforms in core areas like image quality, low light, and handling, shining especially where large sensor advantages count.
