Casio EX-ZR300 vs Fujifilm X-S1: A Hands-On Comparison of Two Small-Sensor Superzooms

As someone who’s handled everything from ultra-high-end full-frame mirrorless rigs to more modest compact cameras, I frequently encounter photographers on a budget who need versatile superzoom cameras for day-to-day shooting - be it for travel, wildlife, or just a reliable “one-and-done” camera. The Casio EX-ZR300 and the Fujifilm X-S1 target this niche: small-sensor superzoom cameras with fixed lenses, known for their convenience and zoom ranges.

Though both cameras emerged around 2011-2012 and share the “small sensor” stamp, they approach the superzoom concept quite differently. After spending quality time shooting with both, I’ve put together this detailed, candid comparison to help you understand which camera could be your trusted companion - and where compromises lie.

Let’s dig in.

How They Stack Up in the Hand: Ergonomics and Design

Right off the bat, you’ll notice a big physical difference. The Casio EX-ZR300 is a compact pocketable travel buddy, measuring a neat 105x59x29 mm and weighing 205 grams. It slips easily into a jacket pocket or a small purse, which is fantastic for casual strolls or grabbing candid street photos without drawing a crowd.

By contrast, the Fujifilm X-S1 is a hefty beast - nearly five times heavier at 920 grams, with dimensions resembling an SLR-style bridge camera (135x107x149 mm). This guy commands grip attention; it’s built to provide a comfortable, DSLR-like hold with a substantial handgrip and clubs for thumbs on the rear.

In real-world use, the X-S1 feels more like a serious camera, designed with prolonged shooting comfort in mind, while the EX-ZR300 is light and grab-and-go. For people prioritizing stealth and portability - think street photographers or light travelers - the Casio wins. But if you prefer a camera that feels substantial and all-business in the hand, Fujifilm’s design is a better fit.

Control Layout and User Interface: Intuition Vs. Function

Moving beyond size, the control schemes illustrate the different philosophies. The Fujifilm X-S1 offers a classic DSLR-esque top plate with dedicated dials for ISO, shutter speed, aperture, and exposure compensation - making manual exposure adjustments quick and tactile. Plus, it sports a tilting FX TFT LCD and a bright electronic viewfinder (EVF) with 100% coverage, an indispensable tool in bright daylight or precise framing situations.

The Casio EX-ZR300 keeps things simpler, opting for a minimalist, compact design. It features a fixed 3” Super Clear TFT screen with 461k dots but no EVF at all. While you get basic controls and modes, the EX-ZR300 lacks physical dials for direct exposure tweaks, pushing more reliance on menus and digital toggles.

This means Fuji’s X-S1 appeals more to enthusiasts who want fine control at their fingertips, especially when switching settings on the fly. Casio’s user interface suits beginners or casual shooters who want fewer clubs for thumbs and a straightforward experience.

Sensor Nuts and Bolts: Size, Resolution, and Image Quality

Let’s talk sensors - the heart of any camera’s image prowess. Both are “small sensor” superzooms but with distinct sensor formats:

• Casio EX-ZR300: 1/2.3-inch BSI-CMOS sensor (~28 mm² area), 16MP resolution
• Fujifilm X-S1: Larger 2/3-inch EXR CMOS sensor (~58 mm²), 12MP resolution, RAW support

The X-S1’s sensor nearly doubles the image area of the Casio, which is a significant advantage in image quality and high ISO performance. Moreover, the EXR CMOS sensor in the Fujifilm X-S1 incorporates Fuji’s well-regarded pixel-level signal processing that delivers a broader dynamic range - around 11.2 EV compared to Casio’s lack of official DxO testing but predictably more limited range. Also, Fuji’s camera has RAW file support, giving photographers serious post-processing flexibility, unlike Casio’s JPEG-only output.

In the lab and field tests, Fuji’s images exhibit cleaner shadows, better color depth (20.4 bits vs unknown for Casio), and less noise at higher ISOs. The Casio, while decent in daylight, struggles with noise and detail retention past ISO 800, with a max native ISO of 3200.

For pixel-peepers, landscape photographers, and those wanting to push their images in post, the Fujifilm clearly wins in sensor capability.

Display and Viewfinder: Framing Tools

The 3" rear LCDs on both are similar in resolution (~460k-461k dots), though the Casio’s Super Clear TFT is fixed and non-articulating, slightly limiting shooting angle flexibility. Fuji’s tilting TFT screen is more versatile, allowing comfortable framing from waist level or awkward positions.

Importantly, the X-S1 includes a built-in electronic viewfinder, which is absent on the EX-ZR300. The EVF is crucial for precise composition in bright sunlight, where LCD screens wash out completely. And with 100% coverage, what you see is exactly what you get.

Casio users may find the lack of viewfinder frustrating outdoors, while Fujifilm’s viewfinder capability is a real plus for field shooters.

Autofocus Systems: Speed and Accuracy in Action

Both cameras rely on contrast-detection autofocus, but implementation differs:

• Casio EX-ZR300: basic contrast detection, single-point and multi-area AF modes but no face or eye detection
• Fujifilm X-S1: 49 AF points, supports continuous AF and tracking, plus contrast detection with face detection

In real-world shooting, the EX-ZR300’s autofocus is slow to lock, especially in low light or when tracking moving subjects. It’s fine for static subjects and casual snapshots but not suited for action.

Conversely, the Fujifilm X-S1 AF system, while not phase-detection, is noticeably faster and more accurate, with continuous AF that tracks moving subjects fairly well for the class. The inclusion of face detection adds reliability to portrait shots.

If you regularly shoot wildlife, sports, or active kids - scenarios demanding quick AF - X-S1’s system will be more satisfying.

Zoom Reach and Lens Versatility

• Casio EX-ZR300: fixed 24-300mm (equivalent), aperture F3.0-5.9
• Fujifilm X-S1: fixed 24-624mm, aperture F2.8-5.6

Sporting a whopping 26x zoom and a brighter maximum aperture on the wide end, the Fuji clearly dominates zoom capabilities. Its fast 2.8 aperture at 24mm helps in lower light, and 624mm reach lets you get much closer to distant subjects.

Casio’s 12.5x zoom covers everyday needs but lacks the long reach or the wider aperture of the Fuji. Both offer macro capability down to 1cm, but X-S1’s lens quality feels more refined and sharp across the zoom range, partially due to its larger sensor and optical stabilization.

For wildlife, sports, or travel photographers needing extreme telephoto power, Fujifilm vastly outperforms Casio in this key category.

Image Stabilization and Low-Light Handling

Both cameras come with image stabilization, but the mechanisms vary:

• Casio EX-ZR300 uses sensor-shift stabilization, which is effective but limited compared to lens-based systems.
• Fujifilm X-S1 relies on optical image stabilization, generally better for longer focal lengths.

Testing reveals that Fuji’s stabilization allows steadier shots at slower shutter speeds, especially at the telephoto end, minimizing blur during handheld shooting.

Considering max native ISO is similar (both capped at 3200), Fuji’s better high-ISO noise control and wider aperture lens translate to superior low-light performance in practice. Casio’s images at night or indoor scenes show noticeably more grain and softer details.

Shutter Speeds, Burst Rates, and Video

• The Casio’s shutter speed caps at 1/2000s, while Fujifilm offers a max of 1/4000s, giving better control for bright conditions and action freezing.
• The X-S1 offers continuous burst shooting at 10fps, which is a boon for sports or wildlife shoots. Casio lacks continuous shooting details or fast frame rates, making it less suitable for action photography.
• Video-wise, both shoot Full HD 1080p at 30fps, using H.264 encoding. However, Fujifilm includes a microphone port, offering better audio input options - advantageous for content creators. Casio has none.

For anyone interested in dynamic subject photography or hybrid photo/video use, Fujifilm is the more complete package.

Build Quality and Weather Resistance

Neither camera boasts weather sealing or ruggedized construction, though Fujifilm’s solid build feels more robust, thanks to its substantial body materials. Casio is more prone to wear with lighter, plastic construction.

Weight differences also imply that the X-S1 is less discreet for street photography but holds up better in challenging conditions.

Battery Life and Storage

• Casio’s battery life rates about 500 shots per charge (NP-130 battery), significantly better than most compact cameras in the same era.
• Fujifilm’s NP-95 battery life isn’t specified officially, but anecdotal testing suggests it’s average (~300-350 shots), typical of larger bridge cameras.

Both accept SD/SDHC/SDXC cards in a single slot, but casual users targeting longevity might favor Casio for this reason.

Connectivity and Extras

• Casio uniquely supports Eye-Fi card wireless connectivity, letting you transfer images via Wi-Fi somewhat hassle-free, which was ahead of its time. Unfortunately, it lacks Bluetooth or NFC.
• Fujifilm has no wireless options but includes a mic input and a more complete exposure bracketing suite (AE and WB bracketing).

Neither provides GPS or modern smartphone integration, but the Casio’s Eye-Fi feature is a nice touch for quick shares.
