When it comes to compact digital cameras, the market in the late 2000s to early 2010s was flooded with options catering to casual shooters and enthusiasts alike. Two contenders standing out in a crowded field are the Casio EX-Z90 and the FujiFilm FinePix Z70 - both offering 12-megapixel CCD sensors, fixed zoom lenses, and a suite of appealing features. But which of these ultraportables truly delivers superior performance, image quality, and value for today’s photographers seeking a small, versatile companion?

I’ve spent extensive hours testing and comparing these models head-to-head, scrutinizing everything from sensor characteristics and autofocus response to ergonomics and real-world shooting results across diverse genres. Whether you’re a portrait lover, landscape aficionado, or seeking a reliable travel buddy, this detailed analysis aims to bring clarity and confidence to your decision.

Let’s dive in.

First Impressions: The Physical Realm Where Feeling Matters

Before pixel peeping or tech talk, the camera must feel right in your hands. Ergonomics can make or break an experience, especially for prolonged shooting sessions.

Upon hold, the Casio EX-Z90 exhibits a truly compact, lightweight frame measuring just 90×52×19mm and weighing 121 grams. Its streamlined profile fits comfortably in the palm, with a traditional rectangular shape lending familiar grip contours despite the absence of pronounced handholds.

In contrast, the FujiFilm FinePix Z70 is only marginally larger (91×57×20mm) and slightly heavier at 124 grams but opts for a rounded, softer design intended to exude elegance and pocketability. The Z70’s curved edges imbue a stylish ultra-compact feel, though arguably at the expense of straightforward ergonomics. For photographers accustomed to more defined grips or tactile buttons, this can feel a bit slippery or less secure.

While neither camera offers physical dials or extensive manual controls, the EX-Z90’s modestly sized but well-placed buttons afford more immediate tactile feedback - especially important when shooting quickly on the go.

Ergonomics verdict: For pure comfort and handling, I lean slightly toward the Casio EX-Z90. The Fuji’s sleek style is attractive but may sacrifice grip security during vigorous shooting.

Controls at a Glance: Which Layout Speaks Photographer?

Examining the top control layouts reveals the design philosophies at play. Both cameras eschew advanced control wheels or manual exposure modes, opting for simplicity suited to casual shooters. Interestingly, the EX-Z90 features a slightly more intuitive shutter button placement paired with a modest zoom toggle ring - facilitating swift framing adjustments.

Meanwhile, the Z70’s top plate is cleaner but offers fewer physical controls, relying more on menu navigation. This is a crucial distinction: photographers who desire quick access to exposure settings or flash modes may find the EX-Z90’s hardware keys more efficient during real-world use.

Neither camera sports an electronic viewfinder, compelling reliance on the rear LCD for composing, which itself reveals deeper differences.

Sensor Technology & Image Quality: The Heart of the Matter

Both the Casio EX-Z90 and FujiFilm Z70 employ a 1/2.3” CCD sensor measuring approximately 6.17 x 4.55mm, offering a 12-megapixel resolution capable of producing 4000x3000-pixel images. A glaring omission is RAW capture - neither camera supports it - meaning photographers are locked into JPEG output with limited post-processing leverage.

Despite similar sensor sizes and pixel counts, subtle differences emerge:

• EX-Z90's sensor max ISO is officially 1600, and it supports a native starting ISO of 64.
• Z70 max ISO is also 1600, but its minimum native ISO is 100.

This translates into a modest dynamic range and color depth typical of CCD sensors from this era. Both cameras include anti-alias filters, reducing moiré but slightly softening detail.

From my on-location image testing under daylight and mixed lighting, the two cameras deliver comparable sharpness and color rendition, although FujiFilm’s processing tends to produce slightly warmer tones and more vivid saturation - a trait often favored by casual shooters for punchier output.

The EX-Z90’s images appear more neutral but provide a faithful rendering of skin tones, which could be essential for portrait work.

Live View and LCD Screen: Composing Without a Viewfinder

Both models incorporate a 2.7” fixed LCD with a resolution of 230,000 dots. This modest pixel count feels dated by modern standards yet remains functional for framing and reviewing shots.

The Casio EX-Z90’s screen exhibits natural color balance and decent brightness, contributing to reliable framing in average lighting. However, its fixed screen lacks any articulation, limiting creative angles.

The FujiFilm Z70 shares similar specifications but leans toward a slightly glossy display that may reflect ambient light more, potentially hampering usability in bright outdoor environments.

Neither camera offers touchscreen capabilities, which limits ease of navigation and speed of AF point selection - though, to be frank, the limited focus functionality (single-point contrast detect autofocus) means touch focus isn’t missed much.

Autofocus Performance: Swift, Precise, or Sluggish?

A compact camera’s autofocus system dictates its effectiveness across genres - especially for action, wildlife, and candid street photography.

Both cameras utilize contrast-detection autofocus, inherently slower and less predictable than phase-detection used in mid-to-high-end cameras. Neither supports manual focusing except for the Casio, which allows limited manual focus adjustment (helpful for macro or creative control).

• The EX-Z90 autofocus is single-point only, lacking any tracking capabilities.
• The Z70 adds rudimentary AF tracking but lacks face or eye detection.

In my real-world testing, both systems achieve moderate success in well-lit conditions but struggle significantly in dimmer environments. Subjects with low contrast or fast movement often challenge focusing accuracy and speed.

Still, the Z70’s AF tracking showed sporadic improvements when following moving subjects, suggesting a somewhat more advanced algorithm underpinning its focus system.

Lens and Zoom Capabilities: Comfort vs Extended Reach

When inspecting the fixed lenses, we observe:

The FujiFilm Z70’s 5x zoom range impresses, extending into telephoto territory useful for casual wildlife or sports snapshots without additional glass. The more modest 3x zoom of the Casio caps at short telephoto, favoring wide-angle shots and portraits more.

Both lenses have relatively slow apertures, limiting low light capabilities and bokeh potential. Personally, I find the Fuji’s longer reach suits photographers needing versatility in framing. The Casio’s lens is arguably better suited for everyday scenes and environmental portraits.

Both cameras offer macro focusing under 10cm, with the FujiFilm finessing a slightly tighter minimum focus distance for close-up exploration.
