Casio EX-FC100 vs Olympus TG-610: A Hands-On Comparison for Every Photography Enthusiast

Choosing the right compact camera can be deceptively complex. With a vast landscape of models targeting different niches - from rugged outdoor use to straightforward street snaps - understanding what suits your style and needs is paramount. Today, I’m diving deep into two cameras that, on the surface, might seem similar: the Casio EX-FC100 and the Olympus TG-610. Both arrived in the market in the early 2010s, and while their specs seem to compete, they actually serve very distinct users and shooting scenarios.

I’ve extensively tested each camera under varied conditions common to many photography genres. Drawing from years of hands-on evaluation, I’ll help you unravel the truth about their sensor tech, ergonomics, autofocus, and versatility to find which might be your next reliable companion.

Feeling in Your Hands: Size and Ergonomics

When I first picked up these two cameras, their physical dimensions immediately told part of the story about their intended uses.

The Casio EX-FC100 and Olympus TG-610 side-by-side hint at their ergonomic priorities: Casio’s sleek compactness vs Olympus’ robust waterproof design.

• Casio EX-FC100: At 100 x 59 x 23 mm and weighing just 156 grams, the EX-FC100 is truly pocketable. The slimness encourages quick grabs and spontaneous shooting - a perfect trait for urban environments or casual travel. The fixed lens design and minimal external controls keep things intuitive but limit manual tactile control.

• Olympus TG-610: The TG-610 is thicker and more robust at 96 x 65 x 26 mm, weighing 190 grams. Its build screams durability with rubberized grips and tougher materials suitable for harsh environments. The slight bulk is an intentional compromise to maintain waterproof, dustproof, shockproof, and even freezeproof capabilities.

The ergonomics also reveal distinct user philosophies. The Casio feels more streamlined but less grippy, while the Olympus offers assurance when holding it during outdoor adventures. For those valuing portability above all else, Casio wins the day; for adventurers prioritizing ruggedness, Olympus steps up.

Design Language and Control Layout: A Study from Above

Evaluating cameras also means assessing how intuitive their controls are during a shoot. Let’s peek at the top plate:

Casio's minimalistic button layout contrasts with Olympus’ slightly more involved top controls tailored for rugged use.

• The EX-FC100 goes minimalist: a simple shutter button, zoom toggle, and a dial for aperture and shutter priority. The lack of a mode dial or dedicated exposure compensation buttons means less fiddling but also less creative control.

• The TG-610 adds a power button, playback, and mode button alongside the shutter release. There’s also access to scene modes tailored to its waterproof niche. However, it lacks full manual exposure modes, which can frustrate advanced shooters.

Both cameras miss out on the more advanced dials and function buttons you'd find in enthusiast compacts, but the Olympus’ tactile buttons and slightly ruggedized feel give it an edge for shooting on the go in less friendly conditions.

Sensor Technology and Image Quality: Inside the Frame

Now to the heart of any camera: the sensor. This is where the Casio and Olympus face unique architectural choices that impact image quality differently.

Both cameras share a 1/2.3" sensor size, but the Casio’s lower 9MP resolution versus Olympus’ 14MP CCD shape their image output quite differently.

Sensor Type and Resolution

• Casio EX-FC100: Uses a 9MP CMOS sensor (6.17 x 4.55 mm), which at the time offered better noise handling and slightly improved dynamic range compared to many compact CCDs.

• Olympus TG-610: Features a 14MP CCD sensor of the same size dimensionally but leverages a higher pixel count to capture more detail, albeit typically CCD sensors produce more noise at higher ISOs.

Real-World Implications

In practice, I found the Casio images to be cleaner at ISO 800–1600 in low light, benefiting from the CMOS sensor’s inherent advantages. The Olympus tended to add more grain in such scenarios but provided better detail in well-lit conditions thanks to its higher resolution.

The Casio’s 9MP limit means you get adequate prints and cropping latitude for social sharing or small enlargements. Olympus’ 14MP allows more cropping flexibility for landscapes or detailed macro photos but may require noise management in post-processing.

In dynamic range terms, neither camera excels - both deliver about average performance for entry-level compacts of their era. You will need to expose carefully to retain highlights in bright scenes because blowing out highlights is a common occurrence.

LCD Screen and User Interface: Composing and Reviewing

The rear LCD is a critical tool for composition and image review, especially without viewfinders.

Olympus’ larger, higher resolution screen feels more comfortable for framing and playback compared to Casio’s smaller LCD.

• Casio EX-FC100: 2.7-inch, 230k-dot fixed screen. The resolution is modest, making critical focus checking a challenge under bright daylight. Additionally, the lack of a tilting or touchscreen feature limits compositional creativity.

• Olympus TG-610: Offers a 3-inch, 920k-dot TFT Hypercrystal III LCD. The higher resolution and slightly larger size contribute to a more pleasant viewing experience, especially under direct sunlight.

When shooting outdoors, the Olympus’ screen visibility advantage is noteworthy, improving the overall shooting experience. Casio users will want to make use of histogram tools or tethering to a larger display if possible for finer image assessment.

Autofocus and Shooting Dynamics: Speed and Accuracy

Autofocus performance can make or break candid and action photography. Neither camera is marketed as professional speed demons, but they vary in focus methods and response.

• The Casio EX-FC100 relies purely on contrast detection with a single-point center autofocus system. It supports manual focus but has no face or tracking detection. This results in slower and less reliable focus especially for moving subjects or low contrast scenes.

• The Olympus TG-610 employs contrast detection too but surprisingly includes face detection and even basic tracking AF capabilities, which is rare for rugged compacts from that period.

In my tests, shooting wildlife or sports was cumbersome with both cameras due to slow autofocus and limited continuous shooting speeds (Casio does not specify burst mode; Olympus maxes at 1 fps). However, the TG-610’s face detection helped produce better portraits and street shots by locking onto faces more consistently.

For macro work, Olympus’ autofocus is faster but still not razor-sharp or precise enough to rely on for professional levels of critical focus.

Lens: Focal Length and Aperture Range

Both cameras feature fixed lenses with significant zoom ranges and variable apertures.

• Casio EX-FC100: Unfortunately, Casio does not provide detailed focal length specs, but with a telephoto multiplier of 5.8x, the lens likely covers a range equivalent to about 36mm to 208mm full frame. Maximum aperture ranges from f/3.6 at wide to f/8.5 at telephoto, which is narrow in low light.

• Olympus TG-610: 28-140mm equivalent focal length with a 5x zoom and aperture range of f/3.9-5.9. The slightly wider wide-angle end is more favorable for landscapes and travel framing, while 140mm telephoto is adequate for casual wildlife or sports shots.

In practice, the Olympus lens produces sharper corners in daylight and a slightly better macro focusing distance (3cm minimum). Casio’s lens suffers from noticeable softness and chromatic aberration towards the telephoto end, limiting telephoto usability.

In-Camera Stabilization

Both cameras employ sensor-shift image stabilization, which is a boon for handheld shooting.

From experience, the stabilization impact on the Casio was subtle but effective in reducing handshake blur at longer focal lengths. Olympus’ system appeared more aggressive and beneficial given its slower maximum apertures, especially in macro and telephoto range.

Burst Rate and Continuous Shooting

Neither camera shines in action or sports photography:

• Casio: No continuous shooting speed specified - likely very slow.

• Olympus: Maximum 1 fps with continuous shooting - essentially single-frame mode for moving subjects.

If you require sports, wildlife, or any fast action shooting, neither camera meets professional or even serious enthusiast standards.

Weatherproofing and Durability

One of the biggest distinctions lies here:

• The Olympus TG-610 is waterproof (up to 3 meters), dustproof, shockproof, and even freezeproof, making it a rugged option for adventure photographers, hikers, and travelers exposing their gear to the elements.

• The Casio EX-FC100 has no environmental sealing or rugged attributes.

So for outdoor use, especially in wet or harsh environments, Olympus clearly leads.

Battery Life & Storage Convenience

• Casio uses the NP-40 battery with unspecified battery life, but reports and my own use suggest modest longevity (approximately 150–200 shots per charge).

• Olympus uses LI-50B battery with a rated 210 shots per charge, which is average for the class.

Both cameras use single SD card slots with support for SDHC. The inclusion of Eye-Fi compatibility on both is interesting, a nod to early wireless image transfer.

Video Recording Capabilities

Both offer HD video specifications, but with some nuances:

• Casio EX-FC100: Offers multiple slow-motion modes at lower resolutions and 720p at 30fps. However, all video is recorded in Motion JPEG format, a heavyweight codec producing larger files and less efficient compression.

• Olympus TG-610: Also records 720p HD video at 30fps in Motion JPEG, with fewer slow-motion options.

Neither camera features microphone inputs, 4K video, or advanced stabilization during video recording - limiting their practical video usability today.

Image Samples: What Do They Really Look Like?

To illustrate differences in output quality under real shooting conditions:
