Casio EX-ZR100 vs. Sony Cyber-shot W370: A Deep Dive into Compact Superzoom Cameras

In the crowded field of early 2010s compact cameras, the Casio EX-ZR100 and the Sony Cyber-shot DSC-W370 stand out as intriguing contenders. Both offer portable form factors, small sensors, and zoom versatility, yet they approach their mission quite differently in terms of featured technologies and photographic priorities. Having spent extensive hours testing these cameras side-by-side, I aim to provide you - a discerning enthusiast or professional looking for a dependable pocket powerhouse - with a holistic, fact-based comparison to guide your next purchase.

Let’s unpack how these two compact cameras stack up across photography disciplines, technical specs, usability, and overall value.

First Impressions & Ergonomics: Handling Matters in a Compact Package

Size and feel often define a camera’s long-term appeal, particularly in compacts designed for on-the-go shooting. The Casio EX-ZR100 is slightly bulkier but still pocketable, measuring 105 x 59 x 29 mm and weighing 204g, while the Sony W370 is a bit leaner at 100 x 57 x 26 mm, tipping the scales at 179g.

This difference, while subtle, translates into ergonomics: the Casio’s heft provides a steadier grip, promoting confidence during longer shoots or in challenging conditions, although it does lose points for bulkier transport. Meanwhile, the Sony’s slimmer chassis makes it easier to slip into smaller pockets, perfect for travel or street photography where discretion is prized.

Both cameras feature fixed lenses and modest button layouts but lack the refined grip contours found on more advanced compacts. The Casio includes manual focus and exposure controls - a definite bonus for users seeking creative input - whereas Sony keeps things simpler with automatic exposure modes only.

Top Deck Controls and Interface: Intuitive or Clunky?

A camera is only as good as its user interface. I put both through their paces examining ease of control during real-time shooting situations.

The Casio EX-ZR100 features a well-laid out top deck with dedicated dials for exposure compensation, manual exposure, and aperture/shutter priority modes, coupled with a clever joystick for AF area selection. This affords flexibility usually absent in cameras at this price bracket.

Sony’s W370, in contrast, uses a pared-down control scheme with fewer physical buttons and no manual exposure modes - perfect for absolute beginners but limiting for enthusiasts wanting to override auto settings.

From hands-on experience, the EX-ZR100 feels like a tool designed with photographic exploration in mind, while the W370 is geared towards quick, casual snaps.

Sensor and Image Quality: The Heart of the Matter

At the core, both cameras sport a 1/2.3" sensor, measuring 6.17 x 4.55 mm, but where they diverge significantly is sensor type and resolution.

• Casio EX-ZR100: Backside-Illuminated (BSI) CMOS sensor, 12 megapixels
• Sony W370: Traditional CCD sensor, 14 megapixels

From a technical standpoint, the BSI CMOS of the Casio typically offers better low-light sensitivity and faster readout speeds owing to its architecture which flips photodiodes and wiring layers to maximize light collection. The Sony’s CCD has historically been praised for color rendition but generally struggles more in low light and at higher ISOs due to noise.

In practical shooting, this means:

• The EX-ZR100 produces cleaner images at ISO 800 and above, retaining more shadow detail - valuable in indoor or evening scenarios.
• The W370 delivers slightly higher resolution images in optimal daylight but suffers from noise buildup when the light drops.

Neither camera supports RAW, a limitation for post-processing enthusiasts, but Casio’s more modern sensor and superior stabilization make it the preferred choice for image quality.

LCD Screen and Viewfinder: Composing Your Shot

Though both cameras discard viewfinders, their rear display performance matters. The Casio’s 3-inch “Super Clear” TFT LCD with 461k dots provides a brighter, sharper live preview than the Sony’s standard 3-inch LCD with 230k dots.

In bright conditions, the EX-ZR100’s screen is more usable - colors remain vibrant and details crisp, aiding in focusing and composition. The Sony’s display can appear washed out, which could frustrate on-the-fly framing decisions.

Neither camera offers a touchscreen or articulating display, so you’re stuck with fixed angles and physical buttons for navigation - a compromise expected at this level.

Lens Performance: Versatility and Optical Quality

Each camera’s built-in lens defines its framing options and optical characteristics:

• Casio EX-ZR100: 24–300 mm (12.5x optical zoom), aperture range F3.0–5.9
• Sony W370: 34–238 mm (7x optical zoom), aperture range F3.6–5.6

So, the Casio offers a noticeably wider field of view at the short end (24mm eq.), better suited for landscapes and interiors, along with an extended telephoto reach allowing more distant wildlife or sports shots.

Optically, however, the extended zoom range on Casio sometimes comes with slight softness and chromatic aberrations at 300mm. Still, it notably surpasses the Sony’s narrower zoom range in flexibility.

The Sony’s lens optics appear sharper in the normal zoom range where users will spend most time, but it loses out on framing diversity.

Autofocus System: Speed and Accuracy in Action

AF is a critical performance metric for many, especially wildlife, sports, and street shooting.

• Casio EX-ZR100: Contrast-detection autofocus, AF tracking enabled, manual focus available
• Sony W370: Contrast-detection autofocus, no AF tracking, manual focus not supported

Casio’s AF system tracks moving subjects within a limited range, assisting with continuous shooting sequences and improving capture probability for action shots - though it’s not phase-detection or hybrid AF, so lag remains.

Sony’s AF is more basic and tends to hunt longer in low contrast or dynamic scenes, compounded by a maximum continuous frame rate of 2 fps versus Casio’s faster 40 fps burst mode (although image buffer size limits actual sequences).

Practically speaking, the Casio serves action shooters better; the Sony is fine for leisurely stills.

Burst Rates and Shutter Performance: Capturing Decisive Moments

The Casio EX-ZR100’s burst shooting at 40 fps is, frankly, impressive for a compact camera of its era. While buffer times restrict sustained bursts, short sequences are excellent for freezing movement.

Sony W370’s more modest 2 fps rate is adequate for casual shooting but inadequate for sports or fast wildlife.

Shutter speeds span from 15 seconds to 1/2000 sec on the Casio, establishing solid versatility for night photography and daylight action, compared to Sony’s 2 seconds to 1/1600 sec range.

Hands-on, I found the EX-ZR100 more reliable and flexible when working in varied shutter speed environments.

Image Stabilization: Keeping Shots Sharp

• Casio uses sensor-shift stabilization
• Sony employs optical (lens-based) stabilization

Sensor-shift tends to compensate best against handheld shake, especially when paired with longer focal lengths. In my tests, the Casio’s stabilization allowed handholding at up to 1/15 second at 300mm equivalent with tolerable sharpness - a major plus for telephoto usability.

Sony’s lens-based system is effective at wider focal lengths but less helpful at full zoom, where I observed slightly more blur from camera shake.

Video Capabilities: Beyond Still Images

While neither camera targets videographers, they do offer entry-level recording:

• Casio EX-ZR100 captures Full HD 1080p at 30 fps using efficient H.264 encoding.
• Sony W370 tops out at 720p HD at 30 fps, and uses Motion JPEG, which results in larger files and lower compression efficiency.

Neither supports external microphones or advanced exposure controls in video mode, but the Casio’s higher resolution footage and superior stabilization provide more usable clips for casual users.

Connectivity and Storage: How Easy Is It to Share and Save?

Both cameras lack wireless connectivity - no WiFi, Bluetooth, or NFC - reflective of their early launch dates.

Storage differs:

• Casio supports SD/SDHC/SDXC cards only.
• Sony accepts SD/SDHC and Sony proprietary Memory Stick Duo formats (including Pro and Pro-HG), adding versatility for users invested in Sony’s ecosystem.

USB 2.0 data transfer and HDMI output are standard on both.

Battery Life and Power Management

Neither manufacturer lists official CIPA battery life numbers for these models, but from extended shooting periods, I note:

• Casio EX-ZR100 uses a rechargeable lithium-ion battery with average endurance - adequate for a day’s casual shooting but top-ups recommended for heavy use.
• Sony W370 uses the NP-BN1 battery, known for modest longevity; heavier zooming and LCD use drains it more quickly.

No USB charging or battery grip options exist for either unit.

Build Quality and Durability

Both cameras employ plastic bodies with no weather sealing, dustproofing, waterproofing, or shock resistance. They are decidedly entry-level in toughness and should be handled with care.

Casio’s slightly thicker chassis may confer a bit more structural rigidity.
