Today, I’m diving deep into a hands-on comparison between the Casio EX-Z280, a compact camera from 2009 aimed at casual shooters, and the Sigma Quattro H, an advanced mirrorless camera announced in 2016 with a unique Foveon sensor designed for discerning photographers.

With over 15 years of experience testing cameras from budget compacts to professional-grade mirrorless beasts, I'll walk you through a practical, no-nonsense examination of what these cameras deliver - covering everything from sensor technology and autofocus to real-world usability across photography genres. Whether you’re a beginner looking for a simple shooter or a pro in need of a specialized medium-format option, this side-by-side will help clarify who each camera suits best.

Let’s get started.

Seeing is Believing: Physical Size and Handling

The first noticeable difference is in their design philosophy and size. The Casio EX-Z280 is a truly pocketable compact measuring 97 x 53 x 20 mm and weighing only 133 grams. Its minimalistic body is designed for everyday portability and straightforward point-and-shoot use.

Conversely, the Sigma Quattro H sports a much larger rangefinder-style mirrorless body at 147 x 95 x 91 mm - clearly aimed at pros or enthusiasts who prioritize image quality and manual control. The Quattro H’s heftier size correlates with added grip comfort and robust construction, including environmental sealing (rain and dust resistance), that the Casio lacks.

From my tests, the Casio feels light and nimble but rather plasticky and cramped for extended use, especially for users with large hands. The Sigma’s body offers reassuring solidity; its larger handgrip and button placements are thoughtfully spaced, lending themselves well to deliberate, manual shooting sessions.

Ergonomics and Handling Summary

• Casio EX-Z280: Ultra-compact and ultra-light, great for casual snapshots on the go but limited tactile control.
• Sigma Quattro H: Bulky but comfortable for long shoots. Weather sealed, better durability, and controls aimed at serious photographers.

Designing for Control: Top-View Layout and Interface

For photographers who value physical controls, the Sigma Quattro H outshines with dedicated dials for shutter speed, aperture, and exposure compensation. The top control layout shows robust, professional-grade customization options, including an articulating top LCD for quick readouts.

The Casio keeps things simple with a fixed-type interface and limited buttons - ideal if you want to point and shoot without fuss but frustrating if you want creative exposure control.

I've found the EX-Z280’s interface smooth enough for beginner use but lacking tactile feedback or dedicated manual exposure modes. The Sigma, however, satisfies the hands-on tinkerer - but without a touchscreen, it takes some time getting used to navigating menus.

Interface Takeaway

• Casio: Simple, limited controls suitable for beginners or casual users.
• Sigma: Professional-style controls with manual overrides; a learning curve but rewarding for fine-tuned shooting.

The Heart of the Image: Sensor Technology and Image Quality

The true differentiation begins with sensor design and imaging performance.

• Casio EX-Z280: Uses a small 1/2.3" CCD sensor, just 28.1 mm² in area, with a 12 MP resolution. It’s typical for compact cameras of its era, capable of acceptable results for casual snapshots but limited in low light, dynamic range, and fine detail.
• Sigma Quattro H: Features a large APS-H size Foveon X3 CMOS sensor, measuring 476.1 mm² - an enormous jump in sensor surface area (17x larger). The sensor boasts an effective 45 MP resolution by capturing red, green, and blue light at every pixel site, yielding extraordinary color fidelity and sharpness.

In hands-on testing under controlled lighting, the Sigma’s images show stunning detail retention and smooth tonal gradations, particularly notable for portrait skin tones and landscapes. The Casio’s images appear soft and less nuanced, with evident noise kicking in above ISO 400.

Technical Insights:

• The Casio’s CCD sensor, while historically excellent for color accuracy, can’t match modern sensor designs in noise control or dynamic range.
• The Sigma’s Foveon sensor captures color differently from conventional Bayer sensors, resulting in vibrant, true-to-life colors and superb resolution without the need for an anti-aliasing filter.

Image Quality Summary

• Casio EX-Z280: Functional for snapshots and daylight, limited for serious work.
• Sigma Quattro H: Elite image quality with expansive resolution and natural color, ideal for fine art and professional use.

Seeing Your Shot: LCD Screen and Viewfinder Usability

The viewing experience further accentuates their target audiences.

• Casio EX-Z280: Comes with a fixed 2.7-inch LCD screen at just 115k dots, offering a basic preview with no touchscreen or articulating capability, and no viewfinder at all. You compose purely on screen.
• Sigma Quattro H: Equipped with a 3-inch fixed screen of 1.62 million dots for a sharp and color-accurate live view. It includes a high-res electronic viewfinder (EVF) with 2.36 million dots and 0.73x magnification, offering coverage close to 100% for precise framing.

In my experience, the Casio’s screen is serviceable but too low-resolution to critically judge focus or exposure in outdoor light. The Quattro H’s EVF is a joy for manual focusing and exposure adjustments, providing the confidence needed for professional work. The LCD’s image preview is crisp enough for assessing shots on the fly.

Viewing Experience Summary

• Casio: Basic LCD-only setup, limited for critical shooting.
• Sigma: Dual viewing options with a high-quality EVF, suitable for demanding compositions.

Capturing Life: Autofocus and Speed

Autofocus systems separate casual convenience cameras from serious tools.

• The Casio EX-Z280 relies on contrast-detection AF with a fixed autofocus point and no tracking, face or eye detection capabilities. Focus speed is slow, and the lack of continuous AF makes capturing moving subjects challenging.
• The Sigma Quattro H gets a hybrid AF system combining phase detection with contrast detection across 9 focus points, featuring face detection and AF tracking that delivers responsive focusing on subjects.

For wildlife and sports, the Casio’s autofocus is quite inadequate, with slow locking and lack of burst shooting. The Sigma, while not a sports-centric speed demon, performs reasonably well for slower-moving subjects and manual selective focus.

Shooting Speed:

• Casio EX-Z280: No continuous shooting; shutter speeds max at 1/2000s.
• Sigma Quattro H: Burst shooting at 3.8 fps, shutter speeds up to 1/4000s.

Given my tests in outdoor action sequences, the Sigma handled focus and frame rate gracefully, while the Casio struggled with any motion.

Lens Ecosystem and Compatibility

• Casio EX-Z280 has a fixed 26-104mm (4x zoom) lens with an f/2.6–5.9 aperture range and a macro focus down to 5cm, making it a simple all-in-one solution with no interchangeable lens option.
• Sigma Quattro H uses the proprietary Sigma SA mount, boasting compatibility with over 70 native lenses across wide-angle, telephoto, and specialty optics, delivering supreme creative flexibility.

Having tested various Sigma lenses paired with the Quattro H, including macro and telephoto primes, I can affirm the optical quality and versatility outperform any fixed-lens compact.
