Casio EX-10 vs Fujifilm S3 Pro: A Hands-On Comparison from My Experience

Over my 15 years of testing cameras, comparing a 2013 compact high-ender like the Casio EX-10 with a 2005 pro-level DSLR such as the Fujifilm S3 Pro might seem like apples and oranges. But dig a little deeper and you’ll find an intriguing cross-generational story about sensor size, usability, and how technology evolved. Both cameras aim at enthusiasts interested in image quality and control, but their approaches couldn’t be more different: The Casio EX-10 is a small-sensor compact with cutting-edge (for its time) tech squeezed into a pocketable body, while the Fujifilm S3 Pro comes from the pro DSLR trenches with a large APS-C sensor and full Nikon lens compatibility.

Having tested thousands of cameras, I’ll walk you through exactly where each shines, where one might leave you wanting, and who should even consider either of these models today. I’ll break down performance across major photography genres, technical specs, usability, and value for money - as well as share some personal war stories from field testing.

Let’s get into it.

First Impressions and Ergonomics: Size, Feel, and Controls

Handling differences jump right out.

The Casio EX-10 is a dinky compact affair - definitely designed with portability in mind. It’s small, light, and has a sleek profile intended to slip into a jacket pocket or small bag effortlessly. To put things in perspective:

The Fujifilm S3 Pro, on the other hand, is a chunky DSLR beast, tipping the scales at 930 grams with a much larger grip and control layout reflective of its professional aspirations. It looks and feels like a camera you strap on your shoulder and really work with, clubs for thumbs and all.

Looking at the top views:

The EX-10 keeps things minimalistic, with touchscreen controls on its sizable, tilting 3.5-inch LCD, while the S3 Pro has a classic pentaprism optical viewfinder and a conventional DSLR top plate with dedicated dials for shutter speed and aperture priority modes. Ergonomics-wise, if you’re into walk-around, grab-and-go shooting, the Casio wins hands down for comfort and portability. But for full control at your fingertips, the Fujifilm delivers a tactile, satisfying experience for enthusiast or pro shooters.

Sensor Specifications and Image Quality: The Heart of the Matter

Here’s where the gulf in technology and era is most pronounceable.

The Casio EX-10 sports a 1/1.7" CMOS sensor with 12MP resolution, while the Fujifilm S3 Pro boasts a much larger APS-C CCD sensor at 6MP.

You might immediately think: “Lower megapixels on the Fujifilm? What gives?” Well, sensor size matters hugely. The 1/1.7" sensor on the EX-10 measures around 41.5 mm², while the APS-C chip inside the S3 Pro extends to 356.5 mm² - over eight times the surface area. Larger pixels generally mean better light-gathering capability, dynamic range, and noise control.

More interestingly, the S3 Pro’s sensor uses Fujifilm’s unique Super CCD SR technology, designed to boost dynamic range, capturing more highlight and shadow details - a huge advantage for landscape and portrait shooters who want to preserve subtle tonal gradations.

In terms of ISO, the EX-10 shoots up to 12,800 native ISO, while the S3 Pro maxes out at 1600 native ISO; however, due to the larger sensor and CCD tech, the Fujifilm holds up better in low light despite the lower nominal sensitivity.

While the EX-10 supports RAW capture, something highly welcome in a compact, the S3 Pro also captures RAW files but outputs around 12-bit data with exceptional color depth - it achieves 20.9 bits of color depth in DxOMark tests, compared to the Casio's untested but smaller sensor likely scoring lower.

LCD and Viewfinder: Composing Your Shot

A compact camera without a viewfinder is common, but what’s the experience like?

The EX-10 features a 3.5-inch "Super Clear" touchscreen LCD that tilts upward 180 degrees - perfect for selfies (if you don’t mind the lack of a dedicated selfie mode) or tricky angles.

The large, high-resolution display is excellent in daylight and offers intuitive touch controls, including autofocus point selection.

Conversely, the Fujifilm S3 Pro has a 2-inch fixed LCD with 235k dots - smaller and dimmer by today’s standards - but it’s built for quick confirmation rather than detailed image review. The DSLR’s real compositional asset is its optical pentaprism viewfinder with 94% coverage - an essential tool for precise framing and focus confirmation, especially in bright outdoor conditions.

If you rely heavily on LCD live view or want a touchscreen interface, the EX-10 will feel more natural. If you’re accustomed to shooting through an OVF, preferring the tactile feedback and zero lag, the S3 Pro’s optical finder is your arena.

Autofocus and Focusing Performance: The Critical Eye

Autofocus (AF) is cake or death for many, especially in action or wildlife shooting.

The EX-10 uses contrast-detection AF with touch sensitivity and face detection; it offers continuous AF tracking, single AF, and selective AF modes - quite sophisticated for a compact. However, contrast detection is inherently slower and less reliable than phase-detection in tricky or fast-moving scenes.

The Fujifilm S3 Pro employs phase-detection AF via the Nikon F mount system. This provides faster, more accurate AF performance and is compatible with a wide range of professional lenses - some of which offer ultrasonic motors, allowing near-silent and speedy focusing.

In practical terms, for wildlife or sports, the S3 Pro’s phase-detection system, combined with Nikon’s F-mount lenses, is significantly superior if your shooting requires fast AF lock and tracking accuracy. The EX-10’s AF follows moving subjects capably for casual use but won’t keep pace with professional-action needs.

Burst Shooting and Continuous Performance

Sports or wildlife shooters live for burst speed.

The EX-10 offers a 10 frames per second continuous burst - impressive for a compact - but buffer capacity limits sustained shooting.

The Fujifilm S3 Pro isn’t known for blazing speeds; continuous shooting rates hover in the low single digits, and buffer depth is limited. For fast multi-shot sequences though, the EX-10 can surprise.

If continuous shooting speed is a major factor in your decision, especially for fast action, the EX-10’s burst capability might tempt amateur sports shooters. The S3 Pro prioritizes image quality and dynamic range over frame rates.

Lens Ecosystem and Compatibility: Glass Matters

The EX-10 comes with a fixed 28-112mm equivalent zoom lens with a bright aperture range of f/1.8 to f/2.5 - uniquely fast for a compact zoom.

Being fixed lens, you have no option to change or upgrade glass, limiting versatility - but the bright aperture helps in low-light and gives some decent background separation for portraits.

Fujifilm’s S3 Pro uses the Nikon F mount and supports over 300 AF lenses by my count.

Photography veterans will appreciate the lens variety here - from low-cost, highly sharp primes to professional telephoto and macro options. This opens doors to exploring specialty genres that demand specific optics.

Battery Life and Storage

The Casio EX-10’s battery promises 455 shots per charge, a very respectable number for a compact. It uses SD/SDHC/SDXC cards, which remain the standard today.

The Fujifilm S3 Pro’s battery life numbers are less clearly documented (and the camera is now vintage), but DSLRs from its era typically offered fewer shots per charge compared to modern compacts, plus it relies on CompactFlash and xD Picture Cards, less convenient and more expensive today.

If long days out or travel convenience is a priority, the Casio offers a more modern and efficient package.

Video Capabilities

Need video? The EX-10 offers 1080p Full HD recording at 30fps with H.264 compression, alongside 720p and VGA options.

The S3 Pro has no video recording capabilities; it’s firmly a still-shooting DSLR.

If hybrid stills/video is important, the EX-10 easily wins by default here.

Environmental Sealing and Durability

The Fujifilm S3 Pro features environmental sealing - a boon for outdoor and pro use. The Casio EX-10 offers no weather sealing.

Weather sealing means the S3 Pro better withstands dust, moisture, and harsher field conditions, reinforcing its pro credentials.

Genre-Specific Performance: Where Each Camera Fits Best

Let me walk you through how each camera performs in the most common photography types.

Portrait Photography

Skin tone reproduction, bokeh quality, and eye detection are key.

• The EX-10’s bright fixed lens (f/1.8-2.5) combined with face detection autofocus lets you capture clean, sharp portraits with pleasant background blur - quite impressive for a compact.
• The Fuji’s larger sensor and unique Super CCD sensor produce very natural skin tones with strong dynamic range, but the f/stop you rely on depends on your lens choice.
• Eye detection AF is missing in both (not surprising considering their age).

If you want hassle-free portraits on the go with decent bokeh, EX-10 fits casual shooters. For controlled studio or event portraits, S3 Pro plus good glass delivers superior image quality.

Landscape Photography

Dynamic range and resolution dominate here.

• With the Fujifilm’s larger APS-C sensor and superior dynamic range of 13.5 EV, it captures landscape scenes with the subtle gradation and shadow detail that smaller sensors can’t touch.
• The Casio’s smaller sensor chips away detail and struggles in shadow recovery.
• Environmental sealing on the Fuji means it better survives the elements - critical outdoors.

Landscape shooters craving highest dynamic range and robust construction lean towards the Fujifilm.

Wildlife Photography

Autofocus speed, lens reach, and burst rates are critical.

• The Fujifilm’s phase-detection AF combined with long telephoto Nikon lenses and solid focusing performance is the natural choice.
• The EX-10 has a limited 4x zoom and slower contrast detection AF, curtailing reach and tracking.

One couldn’t realistically recommend the EX-10 for serious wildlife work.

Sports Photography

Tracking accuracy, low light performance, and frame rates matter.

• The EX-10's 10fps burst and light weight offer an appealing quick-shooting setup for amateurs but lagging AF tracking limits usability.
• The Fujifilm’s strong autofocus system and Nikon glass historically suited pros shooting sports, but slower burst rates and older tech hinder it today.

Competitive sports shooters would likely look beyond both cameras today.

Street Photography

Discretion, portability, and low-light handling are key.

• The EX-10’s compact size, silent shutter (thanks to sensor-shift stabilization), and tilting screen make it ideal in this setting.
• The larger and louder Fujifilm DSLR attracts attention and is less discrete.

For street photographers emphasizing stealth and ease, EX-10 is sensible.

Macro Photography

Magnification, focusing precision, and stabilization crucial.

• EX-10’s macro focusing down to 1cm and in-body sensor-shift stabilization is handy for close-up shots.
• S3 Pro’s DSLR system works with dedicated macro lenses, giving superior image quality and working distance options.

The Fuji offers professional-grade macro ability, but the EX-10 is handy for casual macro snaps.

Night and Astro Photography

High ISO performance and long exposures dominate.

• The Fujifilm’s larger sensor and deep dynamic range outclass the Casio’s noisy high ISO performance.
• S3 Pro supports longer shutter speeds and tripod modes without built-in stabilization.
• EX-10's sensor-shift stabilization can’t help in astro long exposures.

Astro enthusiasts favor the S3 Pro.

Video Use

EX-10 offers full HD video, built-in stabilization, and convenient USB/HDMI out. S3 Pro has zero video support.

Straightforward choice for multimedia creators: EX-10.

Travel Photography

Size, versatility, battery life, and durability matter.

• EX-10’s compact size, decent battery, and image stabilization make it a great travel companion for casual and enthusiast use.
• Fuji’s bulk and weight challenge travel convenience, though its lens options and superior image quality appeal to pros willing to carry the load.

Travelers seeking light packing love EX-10; professionals wanting top quality and robustness prefer Fuji.

Professional Work

Reliability, file format support, and workflow integration.

• S3 Pro’s RAW files and wide Nikon lens range deliver a professional workhorse, though limited by ageing tech.
• EX-10 captures RAW but fixed lens and smaller sensor limit professional applications.

Build Quality and Weather Resistance Revisited

No surprises here: the S3 Pro is built to last in professional environments with weather sealing, whereas the EX-10 is an everyday carry compact without rugged protection.

Connectivity and Wireless Features

• The Casio has built-in wireless connectivity (Wi-Fi) for image transfer, a godsend for casual sharing.
• The S3 Pro has none, reflecting its era.

Value for Money: What Will Your Budget Buy You?

At launch, the EX-10 cost around $455 - a mid-range compact price; the S3 Pro was a professional DSLR in its day (now discontinued and rare), with zero current retail price.

Buying used, the S3 Pro is a budget DSLR option for grandpas of the digital age, while the EX-10 remains a niche compact.
