Today, I’m putting two intriguing contenders head-to-head: the 2013 Casio EX-ZR700 and the 2014 Panasonic Lumix ZS40. Both fall within the small sensor superzoom category, sporting fixed lenses with extensive focal ranges. But beyond specs, how do they perform in real-world photography across genres? Which one justifies its price tag based on your distinct shooting needs? Having personally tested thousands of cameras, including these, I will guide you through a thorough, hands-on comparison to empower your choice.

Getting to Know Your Cameras: Design and Handling First Impressions

Before delving into core imaging capabilities, handling and ergonomics are vital since the camera is your connection to creativity.

Size & Shape

• Casio EX-ZR700: Compact and lightweight at 108 x 60 x 31 mm and 222g, it's easy to carry even in light daily outings.
• Panasonic ZS40: Slightly larger at 111 x 64 x 34 mm and heavier at 240g, but still firmly within pocketable superzoom territory.

In direct handling, the ZS40 feels a touch more substantial, offering better grip confidence - valuable during extended shoots or with longer focal lengths. The Casio’s smaller size makes it appealing for extremely minimal carry setups but sacrifices some physical controls.

Control Layout

Looking at the top controls:

• Panasonic offers intuitive dials and a more pronounced shutter button with zoom ring - ideal for one-handed zooming.
• Casio’s controls are minimalist, leaning on menu diving for advanced settings, which might slow pros after hectic shoots.

Neither camera includes touchscreen or customizable dials, but Panasonic’s tactile controls lend a slightly more professional feel.

Summary: If pocket portability trumps all, Casio excels. But for ergonomics and control finesse, Panasonic ZS40 has the edge.

Peering into the Heart: Sensor and Image Quality Fundamentals

At the core of every camera lies its sensor and image processing prowess - the determinants of resolution, dynamic range, noise handling, color fidelity, and ultimately, the image's clarity.

Both cameras use a 1/2.3-inch CMOS sensor, a common choice in superzoom compacts. However, nuances in resolution and processing set them apart:

The ZS40’s slightly higher resolution and RAW support offer photographers better post-processing latitude. In controlled tests, Panasonic’s Venus Engine processor also yields superior noise control at higher ISOs (notably at ISO 1600 and 3200). Casio’s EXILIM HS 3 processor handles noise decently but shows more visible grain and smudging beyond ISO 800.

In real-world shooting, the ZS40 produces crisper fine detail and more vibrant coloration, particularly noticeable in shadow areas and midtones - valuable for landscapes and portraits where tonal subtlety counts.

Bottom line: Panasonic ZS40 has the sensor and processing edge for image quality, especially for those who prefer RAW workflow and better high-ISO handling.

Sharpening the Focus: Autofocus and Shooting Responsiveness

Autofocus reliability and burst shooting often dictate satisfaction across genres from wildlife to sports.

The Panasonic ZS40 outperforms significantly with continuous autofocus capability combined with a 10 fps burst mode. This allows the camera to maintain sharp focus on moving subjects during rapid fire sequences - ideal for sports, wildlife, or any fast action.

Casio's EX-ZR700, lacking continuous AF and limited to 3 fps, is less suited for tracking erratic motion. Its face detection works well in well-lit situations but sometimes hunts in low contrast or dim conditions.

My hands-on experience: The ZS40 nails focus speed and accuracy in daylight and moderate low light; its AF coverage is wider due to multiple focus points. Conversely, Casio is better for still subjects or casual shooting where speed is less critical.

The Viewfinder and Screen: Your Eye to the Scene

Composing and reviewing images can be make-or-break with regard to usability.

• EX-ZR700: A 3-inch fixed Super Clear TFT LCD with 922k dots. It offers sharp viewing with good brightness but lacks touch input.
• ZS40: Similar 3-inch TFT LCD with 920k dots, also non-touch. However, Panasonic adds a built-in electronic viewfinder (EVF) at 200k dots with 100% coverage - a crucial advantage in bright outdoors where LCD glare hinders framing.

In practice, the ZS40’s EVF turned out indispensible for active shooting under sunlight or when steady framing matters with long reach. Casio’s lack of viewfinder means you’re always reliant on its screen, sometimes forcing awkward framing.

Both cameras’ menus are clear but noticeably dated compared to modern cameras, and neither features touchscreen responsiveness.

Telephoto and Macro: Zoom Reach and Close-up Prowess

For superzoom cameras, the lens range often defines their versatility.

Panasonic’s impressive 30x zoom lens stretches reach to 720mm, dramatically eclipsing Casio’s 450mm maximum. Although the Panasonic’s aperture narrows more at telephoto (f/6.4 vs f/5.9), the extended reach gives significant advantage in wildlife and distant subjects.

Macro capabilities:

• Panasonic claims close focus down to 3 cm, which I found easier for detailed insect or flower shots.
• Casio is respectable at 5 cm but less effective for ultra-close detail.

Image stabilization systems differ:

• Casio integrates sensor-shift stabilization.
• Panasonic uses optical image stabilization (OIS).

In hands-on testing, Panasonic’s OIS generally provided steadier shots at long zooms, reducing camera shake more effectively.

Shooting Across Photography Genres

Let’s see how these cameras stack up in specific real-world photography scenarios.

Portraiture

• Casio: Face detection works well, colors tend to be slightly cooler with reasonable skin tone rendering. Bokeh from the fixed 25mm wide aperture is average, limited by small sensor and aperture range.
• Panasonic: Delivers warmer, more pleasing skin tones with smoother background blur at wide apertures, thanks to larger aperture f/3.3 at wide angle and higher resolution sensor. Face detection plus 23 AF points aid in sharp eye focusing.

Recommendation: Panasonic ZS40’s slightly improved AF and richer color favor portraits, especially if you want easy point-and-shoot portraits with natural skin tones.

Landscape

Dynamic range is crucial here.

• Both cameras have 1/2.3” sensors limiting dynamic range compared to APS-C or larger formats.
• Panasonic’s RAW support enables post-processing techniques to recover highlights and shadows better.
• Casio’s JPEG-only approach restricts latitude but its higher ISO noise control is acceptable for daylight.

Both lack weather sealing, so careful in adverse conditions.

Verdict: Panasonic leads for landscape enthusiasts who want flexibility and slightly higher resolution.

• Panasonic’s 30x zoom, continuous AF, and 10 fps burst clearly position it better for fast-moving wildlife and sports.
• Casio’s 3 fps and shorter zoom make it a casual option only.

Street Photography

• Casio’s smaller size makes it more discreet for candid street shooting.
• Panasonic’s EVF aids framing in sunlight but is bulkier.

Low light performance is marginally better in Panasonic.

Macro Photography

• Panasonic’s 3 cm close focus with OIS helped capture detailed closeups more easily.
• Casio less precise and slower in focusing at macro distances.

Night and Astrophotography

• High ISO noise control favors Panasonic, especially leveraging RAW files.
• Both cameras’ max shutter is 1/2000 s minimum - good but no bulb mode limits very long exposures.
• Neither ideal for serious astro work due to sensor size.
