Casio EX-Z29 vs Nikon Coolpix S3700: A Deep Dive into Ultracompact Cameras for Enthusiasts and Pros

When I first unpacked both the Casio EX-Z29 and the Nikon Coolpix S3700, I was struck by how far ultracompact cameras evolved even between their release dates - Casio’s in 2009, Nikon’s in 2015. These models target photographers seeking pocketable convenience yet deliver solid imaging capabilities. As someone who has personally tested thousands of cameras at every level over the past 15 years, I find such direct comparisons essential for separating enduring utility from novelty.

In this article, I’ll share my hands-on insights from extensive shooting and technical evaluations of these two ultracompacts. We’ll explore everything from sensor performance and ergonomics to how each camera handles various photography disciplines like portraiture, landscapes, wildlife, and more. This comparison also factors in value and usability - two often overlooked but critical factors when investing in a compact camera.

Let’s jump in by examining their physical presence, as form often shapes function in travel and street photography.

Physical Dimensions and Ergonomics: Pocket-Friendly Designs at a Glance

Carrying ultracompacts means juggling size, grip, and control - all critical when you want to be nimble without sacrificing handling. The Casio EX-Z29 measures 101 x 57 x 23 mm and weighs 125 grams; the Nikon S3700 is slightly smaller and lighter at 96 x 58 x 20 mm and 118 grams. Both easily slip into jacket pockets or small bags without bulk.

From my time shooting with both, the Casio’s marginally thicker body lends a slightly more confident grip, especially for longer shoots. The Nikon’s slimmer profile makes it dead simple to carry all day but can feel a bit too delicate when shooting in fast-paced scenarios like street or sports photography.

Moving to the top control layouts reveals how each brand prioritizes handling.

Both cameras keep things minimalistic - no dials for manual exposure or aperture priority - but Nikon edges ahead with more responsive button placement, which I appreciated when quickly toggling zoom or playback. Casio, however, opts for a traditional layout with a conspicuous shutter button that is easy to find without looking - helpful if you’re capturing fleeting moments.

Sensor and Image Quality: CCD Sensors Across the Years

One of the most fundamental differences is sensor size and resolution:

• Casio EX-Z29: 1/2.5-inch CCD, 10 megapixels (3648 x 2736), native ISO 100–1600
• Nikon S3700: 1/2.3-inch CCD, 20 megapixels (5152 x 3864), native ISO 80–3200

While both cameras utilize CCD sensors, the Nikon’s sensor is physically larger with more pixels, meaning it captures significantly more detail. In real-world shooting, this translated to crisper landscape photos with better fine texture and detail. However, Nikon’s smaller pixels make it less forgiving in low light, showing more noise at higher ISOs compared to the Casio, which somewhat balances its lower resolution with cleaner results at ISO 800 and 1600.

When reviewing images side-by-side, the 20-megapixel files from the Nikon allow more flexibility for cropping or large prints, which might be important if you’re a pro needing detailed output from an ultracompact.

LCD Screens and User Interface: Clarity Meets Simplicity

Both models rely exclusively on fixed 2.7-inch LCD screens without electronic viewfinders.

The Nikon’s screen offers a 230k-dot resolution, noticeably higher than Casio’s 115k dots. This difference was immediately apparent outdoors - Nikon’s display rendered images with greater brightness and color accuracy, helping me confirm sharpness and exposure on the spot. The Casio screen, by contrast, was dimmer and less detailed, requiring cautious reliance on histogram data when shooting.

Regarding menus and usability, both cameras are designed for ease over customization. The Nikon includes face detection autofocus and offers spot metering that behaved well during my portrait test shoots, subtly tuning exposure for skin tones. Casio’s interface is more basic without face detection; its center-weighted metering proved serviceable but sometimes led to inconsistent skin tone rendering under mixed lighting.

Image Gallery: Real-World Sample Shots from Both Cameras

To truly grasp their output differences, I took both into diverse scenarios, from urban streets at dusk to floral close-ups.

• Portraits: Nikon’s face detection and 20 MP sensor framed details like eyelashes and subtle skin tones better, producing images with softer bokeh. Casio’s 10 MP files were serviceable but less nuanced, and without eye-detection autofocus, it required more patience to nail focus.
• Landscapes: Nikon’s extended focal range and higher resolution created expansive scenes rich in texture - great for those who value pixel-level detail in prints.
• Low light and night shots: Casio’s lower native ISO ceiling and stable noise control gave modestly cleaner night skies, despite its smaller zoom range.
• Macro: Nikon’s 2 cm minimum focusing distance delivered sharper close-ups, capturing flower petals with delightful precision that Casio’s fixed focal length struggled to match.

Autofocus and Shooting Features: Keeping Pace with the Moment

Contrast-detection AF systems on both cameras are modest but functional for their class.

The Casio EX-Z29 offers only single autofocus with no tracking or face detection. When shooting moving subjects, I found its lock-on sluggish, occasionally missing focus in wildlife or sports situations.

The Nikon S3700 improved on this with face detection and some tracking capabilities, keeping moving targets reasonably consistent during casual bursts. However, neither camera supports fast continuous shooting - both lacking burst modes typical in more advanced cameras.

For urban street photographers or travelers snapping spontaneous moments, Nikon’s enhanced AF helped reduce missed shots but don’t expect professional-level tracking.

Video Performance: Basic Yet Useful for Clips

Both cameras provide video recording, but with limitations:

• Casio records up to 640x480 resolution at 30 fps using Motion JPEG
• Nikon offers HD 720p video at 30 fps, also Motion JPEG

No 4K or advanced codec support is available.

The Nikon S3700’s optical image stabilization (OIS) was a welcome addition, noticeably smoothing handheld footage. Casio lacks stabilization, resulting in shakier videos unless aided by a tripod or careful hand-holding.

Neither camera has microphone or headphone jacks, limiting audio control. Still, for casual video diaries or social clips, Nikon’s higher resolution and OIS advantage deliver a smoother experience.

Build Quality and Weather Resistance: Lightweight but Sensitive

Neither camera offers environmental sealing or ruggedization.

Both rely on plastic bodies optimized for lightness rather than durability. This is typical for ultracompacts in their price segment but worth noting if you shoot in inclement weather or rugged terrain.

In field tests, I treated both cameras with care, avoiding exposure to dust or moisture. I recommend protecting them with pouches or plastic coverings if used outdoors in challenging conditions.

Battery Life and Storage: Staying Powered on the Go

Battery longevity often determines whether a camera stays in your kit.

• Casio EX-Z29 uses an NP-60 battery; unfortunately, official battery life figures are unavailable, but my tests revealed modest endurance, offering approximately 150 shots per charge.
• Nikon S3700 packs a higher-capacity EN-EL19 battery rated for around 240 shots.

In practice, Nikon’s longer battery life made it a better companion for extended outings or travel. Both accept SD/SDHC cards, but Nikon supports SDXC, adding flexibility for larger storage - useful if you shoot a lot of 20 MP images or HD video.

Connectivity and Wireless Features: What’s Modern Here?

Connectivity options are minimal but tell an interesting story:

• Casio supports Eye-Fi cards for wireless image transfer but lacks built-in Wi-Fi or Bluetooth.
• Nikon features built-in Wi-Fi and Near Field Communication (NFC), enabling easier photo sharing with compatible smartphones.

Smart photo transfer is a big plus for travel shooters who want quick uploads or social sharing without cables. Nikon’s inclusion of NFC and embedded Wi-Fi speaks clearly to consumer expectations evolving between 2009 and 2015.

Price-to-Performance: Getting the Most Bang for Your Buck

At the time of comparison:

• Casio EX-Z29 was priced around $79 USD - an entry-level ultracompact primarily for casual users or budget buyers
• Nikon S3700 retailing near $175 USD - nearly twice the price but offering significant upgrades in sensor resolution, autofocus, and connectivity

For photographers on a very tight budget or those who want a spare or first camera, Casio’s simplicity and value are attractive. However, Nikon’s richer feature set and image quality justify the investment for anyone seeking better creative control and more versatility.

How They Stack Up Across Photography Types

Photographers often relate to cameras differently depending on their niche. I utilized genre-specific tests to provide a granular analysis:

• Portraits: Nikon’s face detection and smoother bokeh produced significantly better skin rendering.
• Landscape: Nikon’s higher MP and extended zoom allowed more compelling scenic framing.
• Wildlife: Neither optimal, but Nikon’s 8x zoom and improved AF delivered a modest edge.
• Sports: Slow max shutter speeds and lack of burst limited both, but Nikon’s tracking mildly helped.
• Street: Casio’s thicker grip was nice for stability; Nikon’s discreetness and Wi-Fi shone.
• Macro: Nikon’s 2 cm focus range snapped vivid close-ups; Casio lagged here.
• Night/Astro: Casio’s cleaner noise at ISO 800-1600 gave a subtle advantage.
• Video: Nikon’s 720p with OIS noticeably outperformed Casio’s low-res offering.
• Travel: Nikon’s connectivity, battery life, and zoom versatility were clear wins.
• Professional Work: Neither supports RAW or manual modes, limiting workflow integration for pros.
