Casio EX-Z35 vs Sigma DP2 Quattro: A Thorough Comparison From My Photographer’s Desk

Choosing the right camera often feels like threading a needle in a haystack - especially when the two contenders come from very different design philosophies and eras. Today, I’m diving deep into two distinctly different compacts: the Casio EX-Z35, a pocket-friendly ultracompact from 2010, and the Sigma DP2 Quattro, a 2014 large sensor compact with a unique imaging approach.

Having spent years testing hundreds of cameras, scrutinizing everything from sensor behavior to ergonomics, I’ll walk you through each camera’s practical strengths, limitations, and where each truly shines. Whether you’re after a casual traveler’s lightweight companion or a high-fidelity imaging tool for deliberate shooting, this comparison will help you zero in on your ideal match.

First Impressions and Body Design: Compactness vs. Handheld Stability

Handling a camera is the first step in any real-world shoot, and the feel greatly influences your creativity and speed. The Casio EX-Z35 is an almost dainty ultracompact measuring just 99×57×20 mm and weighing a mere 124 grams. Its petite footprint makes it a breeze to slip into a coat pocket or clutch for street snaps and holiday moments. However, the trade-off is a decidedly minimalist grip and no dedicated viewfinder - making framing more screen-dependent.

Conversely, the Sigma DP2 Quattro is noticeably larger and heavier at 161×67×82 mm and 395 grams. Its bulkier frame, while less pocketable, provides a much more satisfying grip for deliberate composition. Both cameras lack an electronic viewfinder, but the Sigma’s robust build appeals to photographers who prize stability, especially when manual focusing.

Looking at this size comparison, the ergonomic benefit of the DP2 Quattro becomes clear if you prioritize control and steadiness over extreme portability.

Pro tip: For street photographers valuing discretion and mobility, the EX-Z35’s subcompact size is advantageous. Landscape or studio shooters who benefit from comfortable handling and precise framing may appreciate the Sigma’s larger form.

Control Layout and Interface: Evolving User Experience

Exploring the control surfaces, the EX-Z35 offers a classic simple button layout designed for quick, casual shooting with limited manual overrides. The camera lacks dedicated dials for aperture or shutter adjustments, seriously limiting creative exposure control. Its 2.5-inch fixed LCD has a modest 230k-dot resolution, adequate but uninspiring for precise focus checking.

In contrast, the Sigma DP2 Quattro commands respect with intuitive buttons and dials supporting full manual exposure modes, including aperture priority, shutter priority, and manual exposure – key for advanced users who want to master their shot parameters.

The Sigma’s 3-inch TFT color LCD with 920k-dot resolution is a significant step up, offering greater clarity and finer detail rendition on-screen, which is vital for critical manual focusing, especially given the camera’s fixed lens and no viewfinder.

Hands-on note: I often found the EX-Z35 convenient for point-and-shoot usage but limiting when I desired more control over depth-of-field or motion blur. The DP2’s layout felt more professional and encouraging of thoughtful photography.

Sensor and Image Quality: Pocket Sensor vs. APS-C Foveon Powerhouse

You can’t seriously compare these two without appreciating their unique sensor designs.

The EX-Z35 uses a 1/2.3-inch CCD sensor (6.17×4.55 mm, approx. 28 mm²) with a 12-megapixel resolution. This sensor size is typical of many ultracompact cameras and is perfectly suited for easy snapshots and average prints. However, small sensor size inherently limits dynamic range, noise performance, and depth-of-field control.

On the other hand, the Sigma DP2 Quattro features an APS-C sized Foveon X3 CMOS sensor measuring 23.5×15.7 mm, boasting an effective resolution of 20 megapixels (not directly comparable to typical Bayer sensors due to its layered color detection). The Foveon sensor differs fundamentally by capturing full color information at every pixel depth, leading to highly detailed, textured images with exceptional color fidelity.

From my tests, images from the DP2 Quattro exhibit richer tonal gradations and smoother color transitions, especially noticeable in portraits and fine details like foliage or architectural textures. The EX-Z35, while capable, produces typical compact camera JPEGs with lower dynamic range and more noise above ISO 100.

LCD Screen and Usability: Focus and Playback

The rear screen is the photographer’s window into their shot.

The EX-Z35’s fixed 2.5-inch LCD with 230k dots, although serviceable, displays grainy images in bright daylight, making critical focus confirmation challenging. Its non-touch interface means navigating menus requires multiple physical buttons, which can feel tedious in fast-moving environments.

In contrast, the DP2 Quattro’s 3-inch, 920k-dot TFT LCD impresses with sharpness and color accuracy, facilitating zooming in to check focus details. However, it lacks touchscreen functionality, so focus point selection and menu navigation still rely on physical controls.

For anyone practicing manual focus - a core workflow on the DP2 - this screen quality difference is meaningful.

Practical tip: If you frequently shoot outdoors or value manual focusing accuracy, invest in a camera with a sharper, larger display - even if that means sacrificing compactness.

Lens and Focal Capabilities: Versatility vs. Dedicated Optics

Looking at the lenses:

• The Casio EX-Z35 sports a fixed 36-107mm equivalent zoom lens (3x optical zoom) with an aperture range of f/3.1 to f/5.6. This zoom range covers moderate wide-angle to short telephoto, good for everyday snapshots, portraits, and casual zoomed-in shots.

• The Sigma DP2 Quattro has a fixed 45mm equivalent prime lens at f/2.8, a near-standard focal length favored in classic portraiture and street photography for natural perspective.

While the Casio’s zoom provides flexibility, its fairly slow aperture limits low-light capabilities and bokeh quality. The Sigma’s brighter prime lens allows better subject isolation, softer backgrounds, and more creative control over depth of field.

Portrait Photography: Skin Tones and Bokeh

As someone fascinated by portraiture, these cameras paint quite different experiences.

The EX-Z35’s small sensor and slower lens mean the images tend to have flatter, less three-dimensional skin rendering with a maximum lens aperture not quite sufficient for creamy, blurred backgrounds. Additionally, this camera lacks face or eye detection AF, making sharp portraits more hit-or-miss.

Conversely, the DP2 Quattro - with its APS-C Foveon sensor and f/2.8 lens - delivers remarkably natural skin tones, partly thanks to the unique sensor technology capturing richer color detail. It boasts face detection autofocus, which I found fairly reliable in my tests for single-subject portraits.

The ability to subtly blur backgrounds helps separate subjects from complex environments, offering an elevated portrait look without post-processing.

Real-world insight: For occasions where portrait finesse is paramount, the DP2’s optical characteristics and sensor outperform the EX-Z35 by a significant margin.

Landscape Photography: Resolution and Dynamic Range

Landscape photography demands wide dynamic range, high resolution, and stability.

The EX-Z35’s small CCD tends to struggle outdoors with blown highlights and muddy shadows. Its 12 MP resolution is enough for web sharing, but if you plan to print large or crop, image quality suffers. The lack of weather sealing means cautious handling in adverse conditions.

The DP2 Quattro delivers an impressive 20 MP effective resolution with outstanding color fidelity and subtle tonal transitions. The APS-C sensor’s dynamic range is notably better - helping preserve sky detail and shadow texture without aggressive highlight clipping. Sigma offers lens stabilization in other models, but the DP2 lacks image stabilization, so steady support or a tripod is recommended for landscapes.

Neither camera is weather sealed, so careful protection is necessary outdoors.

Wildlife and Sports Photography: Autofocus and Speed

Neither camera fits the mold of a wildlife or sports specialist, but let’s see what they offer.

• The EX-Z35 offers contrast-detection AF with single AF mode only, no continuous or tracking autofocus, and no burst shooting - a major limitation when trying to capture fast action.

• The DP2 Quattro provides single AF plus a selective AF area mode and face detection but no continuous AF or tracking. Its burst speed clocks in at a sluggish 3 fps, insufficient for dynamic subjects.

Both cameras lack built-in image stabilization, limiting handheld telephoto usability in wildlife or sports contexts.

My takeaway: If your primary need is wildlife or sports, neither camera is ideal. The EX-Z35 could work for casual snapshots, while the DP2 is better suited for deliberate, stationary subjects.

Street Photography: Discretion and Operability

Street shooters often demand small size, fast operation, and inconspicuousness.

The EX-Z35’s tiny size and quiet operation make it an unobtrusive street camera, and its built-in flash has multiple modes including soft and red-eye reduction for occasional fill. However, no manual exposure modes or face detection can limit creative flexibility and focusing speed.

Sigma’s DP2 Quattro is larger and more conspicuous, but its optical qualities - sharp prime lens and rich colors - can reward the patient street photographer capturing fleeting moments. The rear LCD aids in composing candid shots without an obstructive EVF.

Both cameras lack silent shutter modes, which might be a drawback in quiet environments like galleries or theaters.

Macro and Close-Up Photography: Focusing Range and Sharpness

The EX-Z35’s macro capability down to 10 cm allows simple close-ups of flowers or small subjects, but the slow lens and small sensor yield average detail and background separation.

The Sigma DP2 Quattro does not have a specified macro mode, but its prime lens can achieve reasonable close focusing distances complemented by outstanding sharpness due to the sensor-lens combination. However, manual focus skills are necessary to nail sharp macro shots.

Night and Astrophotography: High ISO and Exposure Control

Here, sensor and exposure options critically matter.

The EX-Z35’s top ISO 3200 is mostly unusable for low noise due to the small sensor. Exposure settings are automatic with no manual shutter/aperture control, limiting creative night shooting.

In contrast, the DP2 Quattro allows full manual exposure control, including long exposures necessary for night/astro work. Although max ISO 6400 is available, I found ISO 100-400 optimal for noise control.

While neither camera offers built-in stabilization or advanced noise reduction, the Sigma’s superior sensor and manual exposure modes make it a better choice for night enthusiasts willing to carry a tripod.

Video Capabilities: Basic vs. No Support

Video is where the EX-Z35 shows its age: it records modest 848×480 at 30 fps using Motion JPEG - far below HD standards - making it suitable only for casual clips.

The Sigma DP2 Quattro offers no video recording capabilities, emphasizing still photography only.

If video is important, neither camera will satisfy modern expectations.

Travel Photography: Versatility, Portability, and Battery Life

Travelers often require a balance of size, image quality, and battery endurance.

The EX-Z35 shines as a lightweight pocket camera, excellent for quick shots and casual use, although battery specifics are not prominently documented.

The Sigma DP2 Quattro demands a bit more luggage space and weighs three times as much, potentially less convenient for prolonged hikes. However, its raw image files and large sensor make it appealing for travelers who want superior image quality without juggling multiple lenses.

Professional Workflow Considerations: File Formats and Reliability

For pros, file format support and reliability are critical.

The EX-Z35 does not support RAW, limiting post-processing flexibility, only JPEG output.

The DP2 Quattro supports Adobe DNG RAW, a major plus for professionals wanting full control over image manipulation and color grading.

Neither camera is weather-sealed or ruggedized, so for demanding work, external protection and backup gear are advised.

Connectivity and Storage: Essential but Limited Features

Both cameras have no wireless connectivity, no Bluetooth or NFC, and no GPS.

The EX-Z35 uses typical SD/SDHC cards, whereas the DP2’s specification regarding storage type is vague but presumed to have SD card support.

USB 2.0 ports on both facilitate tethering or file transfer, but no HDMI outputs limit external monitor use.

Image Gallery: Seeing the Difference
