Casio EX-S5 vs Sony Alpha a3500: A Hands-On Deep Dive into Two Very Different Cameras

When you first glance at the Casio EX-S5 and the Sony Alpha a3500, it’s a bit like putting a vintage sports car next to a modern sedan. They’re designed in different eras for very different purposes. Yet, each has its own charms, quirks, and practical applications. After personally testing these two cameras extensively - spanning urban street shoots, portrait sessions, landscapes, and a smattering of video experiments - I’m here to guide you through their respective technical merits and performance realities.

Whether you’re an enthusiast eyeing a budget-friendly compact, a beginner dipping toes into interchangeable lens systems, or even a pro looking for a second, lightweight camera, this comparison should illuminate which fits your creative journey best. Buckle up, we’re about to explore these two cameras from their sensor pulse to their shoulder-feel ergonomics.

A Tale of Two Body Types: Ultra-Compact Pocketability vs. SLR-Style Mirrorless

Right off the bat, the physical differences are stark. The Casio EX-S5 fits snugly into the "ultra-compact" category - tiny, sleek, and designed to disappear effortlessly in your pocket or purse. Measuring a mere 102 x 35 x 22 mm and weighing just 100g, it’s almost like carrying a high-tech credit card camera. In contrast, the Sony a3500, being a classic entry-level mirrorless, has an SLR-style body clocking in at 128 x 91 x 85 mm and tipping the scales around 411g - quite a chunkier little fellow.

During my testing, the Casio's ultra-slim profile was perfect for those spontaneous street shots where discretion is key. However, that slimness comes at the cost of a smaller grip and controls that aren’t quite as comfortable during prolonged handheld sessions. The Sony's more substantial grip felt reassuring for extended shooting - I noticed less hand fatigue, particularly with longer lenses attached.

If you prize ultimate portability for casual snapshots - and occasionally macro - Casio’s design wins. But if you’re after a camera meant to be more of a serious daily driver, the Sony alone offers the rubber grips, custom buttons, and a heft that translates to stability.

Control and User Interface: Minimalist vs. Semi-Pro Flexibility

Moving to the camera tops and backs reveals the contrast between minimalism and more full-featured control.

The Casio EX-S5 is barebones: a fixed 2.7” LCD, no viewfinder (find me one in an ultra-compact of that vintage), and simple exposure controls limited to preset modes and no manual exposure. By contrast, the Sony a3500 sports a larger 3.0” fixed TFT LCD with much higher resolution and an electronic viewfinder offering 100% coverage and 0.47x magnification. This alone changed how I framed shots - the EVF improved visibility in bright sunlight dramatically, something Casio’s modest screen struggled with.

Sony’s control layout is more traditional with explicit dials for shutter priority, aperture priority, and full manual exposure modes. This means photographers who enjoy creative control will appreciate being able to dial in exact settings on the fly without digging through menus - a luxury the Casio lacks.

Both cameras lack touchscreen functionality, so navigation is via physical buttons and dials. Sony’s interface feels more thoughtful and responsive, as expected for a camera designed years later targeting enthusiast photographers. The Casio’s control simplicity is a trade-off: it’s easy for beginners but limiting for more advanced users.

Sensor Size and Image Quality: Tiny CCD vs. APS-C CMOS

At the heart of any camera is its sensor, and this is where the Sony a3500 makes a pronounced leap.

The Casio EX-S5 relies on a diminutive 1/2.3-inch CCD sensor with a 9-megapixel resolution, producing 3648 x 2736 images at a maximum ISO of 1600. Meanwhile, the Sony a3500 boasts a much larger APS-C CMOS sensor (23.5 x 15.6 mm) with 20 megapixels resolution (5456 x 3632) and a native ISO range stretching from 100 to 16,000. This sensor size difference - roughly 13x the surface area - is not a mere spec sheet footnote but profoundly impacts image quality.

Through side-by-side shooting tests under varied lighting:

• Dynamic range was markedly better on the Sony, pulling out shadow details delicately while preserving highlight textures. The Casio’s sensor exhibited rapid highlight clipping and muddy shadows.
• Noise performance at ISO 800 and above heavily favored the Sony. Casio’s images at ISO 800 started showing blotchy chroma noise and loss of detail, while Sony’s APS-C kept noise well suppressed up to ISO 3200.
• Color depth and subtle palate shifts were richer on the Sony, benefiting from the modern BIONZ processor, even if RAW support (absent on Casio) is key for best versatility.

In practical landscape and portrait shooting, the Sony’s image superiority is palpable, especially once you factor in larger sensor bokeh potential and better low light handling.

Screens and Viewfinders: How You See Your Shot Matters

Neither camera sports touchscreen capability, but their live view experience differs significantly.

The Casio’s 2.7-inch 115k-dot LCD lets you compose and review images but is dim in bright conditions. The Sony a3500’s 3.0-inch 230k-dot screen offers better brightness and clarity. More important for me was the Sony EVF - a must for tracking fast action or in tricky lighting situations where LCD glare can ruin compositions. The lack of any viewfinder on the Casio means you rely solely on the LCD, limiting compositional flexibility when shooting at arm’s length or in harsh direct sunlight.

For anyone serious about manual composition and prolonged shooting sessions, the Sony’s viewfinder experience is a game-changer.

Autofocus and Speed: Contrast Detection on Both, but Sony’s More Advanced

Both cameras use contrast-detection autofocus without phase detection - common for their respective releases and categories - but the Sony’s 25 AF points and face detection system represent a significant upgrade over Casio’s single center-point AF with no face or eye detection.

In real-world usage, the Sony a3500 focused noticeably faster and more reliably across a range of conditions including:

• Portraits: Sony’s face detection kept focusing locked on eyes more accurately.
• Street and wildlife: Casio struggled to track anything moving quickly, often hunting for focus with visible lag.
• Continuous AF: Only Sony supports AF tracking and continuous focus, enabling burst shooting of moving subjects better.

Maximum shutter speed on Sony is 1/4000s compared to 1/2000s on Casio - again a point favoring shooting fast action or wide apertures in bright light.

Flexibility with Lenses: Fixed and Limited vs. Vast Sony E-mount Ecosystem

Fixed-lens convenience is a Casio hallmark, and the EX-S5’s lens, while unspecified in focal length in official specs, operates with a digital zoom multiplier of 5.8x and max aperture from f/3.1 to f/5.6. No zoom stabilization, no manual aperture control. This makes it ideal for casual snapshots but limits creativity and reach.

The Sony a3500 shines with over 120 available native E-mount lenses, spanning everything from ultra-wide primes to telephoto beasts - crucial for wildlife, sports, or macro work with fast glass. This lens ecosystem opens up vast creative freedom, an area where the Casio simply cannot compete.

Battery Endurance and Storage: Essential Practicalities

The Casio EX-S5 uses a small NP-80 battery with no published battery life figures, but testing revealed modest endurance - about 150 shots per charge, typical for compacts from that era. The Sony a3500’s larger NP-FW50 battery provides approximately 470 shots per charge according to CIPA standards, which held true in my real-world tests with moderate LCD use.

Both rely on a single SD (or SDHC) card slot with USB 2.0 connectivity; however, Casio supports Eye-Fi wireless cards - a novelty but essentially outdated today. Sony’s inclusion of an HDMI output lets you offload or preview content easily - a boon if you want to review images on a larger screen quickly.

Video Capabilities: Basic vs. Full HD

No 4K here, but a big gulf in frame size and quality:

• Casio shoots max 848x480 video at 30fps (Motion JPEG), which is rather limited for modern uses.
• Sony can record Full HD 1920x1080 video at the same frame rate with better compression formats (AVCHD, H.264).

Sony’s video quality and file flexibility make it more desirable for casual vloggers or hybrid shooters, even if it lacks microphone inputs.

Durability and Weather Sealing: Neither Built for Ruggedness

Neither camera offers environmental sealing or rugged protections such as dustproofing or waterproofing, which isn’t surprising given Casio’s ultra-compact construction and Sony’s entry-level classification. Neither camera is shockproof, crushproof, or freezeproof.

If you shoot often outdoors or travel in adverse conditions, you’ll want to consider protective housing or alternative models.
