Comparing the Casio EX-Z270 and Nikon Coolpix S7000: Which Ultracompact Camera Wins in 2024?

Choosing an ultracompact camera nowadays can feel like navigating a maze of specs, genres, and user needs. Two cameras from different eras - the 2009 Casio EX-Z270 and the 2015 Nikon Coolpix S7000 - offer intriguing contrasts for enthusiasts seeking pocketable convenience with solid performance. Having extensively tested cameras across genres for over 15 years, I'm here to guide you through a detailed comparison that looks beyond spec sheets and into real-world usability and photographic value.

If you’re considering either of these models - perhaps browsing used gear or a tight budget - I’ll break down how each camera performs technically, which genres they’re best suited for, and where compromises show through. So let’s get comfortable, and take an expert journey into the strengths and weaknesses of the Casio EX-Z270 and Nikon Coolpix S7000.

Size, Build, and Handling - The Physical Feel Matters More Than Ever

Starting with the basics, size and ergonomics dictate how often you’ll actually use a camera day to day.

The Casio EX-Z270 is a true ultracompact, measuring just 97 x 55 x 22 mm and weighing a featherlight 111 grams. It slips effortlessly into a pocket, perfect for casual snapshots when size is paramount. However, its diminutive size brings some compromises in grip comfort - especially for those with larger hands - and control placement.

The Nikon Coolpix S7000, while still compact, is noticeably larger and heavier at 99 x 60 x 27 mm weighing 165 grams. The extra heft immediately conveys a more robust feel and improved grip ergonomics. The body’s modest bulge and slightly larger footprint make holding it steadier during prolonged shooting sessions.

Looking at the control layouts side-by-side, the Nikon offers a marginally more intuitive top-plate design, with dedicated buttons for key shooting modes and a smoother zoom rocker. Casio’s controls feel minimalistic and somewhat dated, reflecting its earlier release era. The Nikon's inclusion of a customizable self-timer and timelapse recording button also adds modern utility straight out of the box.

In practice, if you prioritize pocketability above all else, the Casio EX-Z270 can fade into your daily carry unnoticed. But if you like a reassuring grip and more tactile controls, the Nikon S7000 delivers a better physical experience, albeit at the cost of greater size.

Sensor and Image Quality - The Heart of Photography

Both cameras feature smaller-than-APS-C sensors typical for ultracompacts but differ in sensor technology, resolution, and expected output quality.

The Casio EX-Z270 sports a 1/2.5-inch CCD sensor with 10 megapixels, which was standard for its launch time. CCD sensors tend to deliver decent color depth and dynamic range for casual use, but struggle with noise at higher ISO settings. The EX-Z270 maxes out at ISO 1600, which, combined with a relatively small sensor area (~24.74 mm²), leads to noisy images beyond ISO 400 in low light.

In contrast, the Nikon S7000 uses a slightly larger 1/2.3-inch CMOS sensor with 16 megapixels, offering more resolution and better low-light capability, supported by a maximum ISO of 6400. CMOS sensors generally enable faster readout speeds and improved noise control. The Nikon’s sensor area measures approximately 28.07 mm², somewhat larger, enhancing light-gathering ability.

What does this mean practically? The Nikon has a clear edge in image clarity, especially in dim conditions or where cropping is needed without sacrificing detail. The Casio might suffice for bright, everyday scenarios but struggles in challenging light.

For testing, I conducted side-by-side shootouts in typical landscape and indoor lighting. The Nikon images showed visibly richer details, deeper shadows with less noise, and more accurate color rendition, while the Casio images appeared softer and noisier beyond ISO 200.

LCD Screens and User Interface - Your Window into the World

A camera’s rear screen serves as the photographer’s primary viewfinder and feedback tool, so its size, resolution, and usability can significantly influence shooting comfort.

The Casio sports a 2.7-inch fixed LCD with a resolution of just 115k dots, which is undeniably low by today’s standards. The limited resolution makes assessing focus and image sharpness via the screen challenging. Colors appear muted, and brightness falls off significantly outdoors, especially under sunlight glare.

The Nikon S7000 offers a larger 3-inch screen with 460k dots resolution, resulting in crisper previews and easier image reviewing. Despite lacking touchscreen capability, its brightness and contrast perform well in varied lighting, improving framing accuracy and menu navigation.

Neither camera includes an electronic viewfinder (EVF), so the LCD remains the sole framing tool. For moving subjects or bright daylight, the Nikon’s better LCD usability is a noticeable advantage.

Autofocus and Shooting Speed - Capturing the Decisive Moment

For action, wildlife, or sporadic street shooting, autofocus reliability and continuous shooting speed are crucial.

The Casio EX-Z270 uses a contrast-detection autofocus system, limited to single AF mode with no face or subject-detection capabilities. This setup works for static scenes but struggles tracking moving subjects or adjusting quickly in dynamic settings.

The Nikon S7000 improves significantly with contrast-detection AF but adds face detection and even AF tracking, allowing for better focus retention on subjects moving within the frame. Continuous shooting clocks at 9.2 frames per second, impressively fast for this category.

In real-world use, the Casio’s AF felt sluggish and unreliable for anything beyond straightforward shots, making it a poor choice for sports or wildlife photography. The Nikon’s autofocus was responsive and consistent for casual action photography - though not at a professional sports level.

Lens Reach and Versatility - The Zoom Factor

Lens zoom range often defines how versatile an ultracompact camera is, especially when fixed lenses limit your options.

The Casio EX-Z270 offers a modest 4x zoom spanning 28-112mm equivalent, suitable for everyday snapshots, portraits, and some moderate close-ups. However, the relatively narrow zoom range restricts reach for wildlife or distant subjects.

By contrast, the Nikon S7000 packs a powerful 20x zoom covering 25-500mm equivalent focal length. This extensive zoom allows photographers to frame wide landscapes or pinch in on distant details, significantly boosting versatility.

My testing of distant subjects - birds perched far away or candid street scenes across streets - showed the Nikon’s advantage in isolation and framing freedom. The Casio’s limited zoom felt restrictive beyond tight indoor or close-up scenarios.

Image Stabilization and Low-Light Performance

Image stabilization greatly complements small sensor cameras to reduce blur from handshake, especially at slower shutter speeds or longer focal lengths.

The Casio relies on sensor-shift image stabilization, which works passably but is limited by its older tech. In dim conditions or at max zoom, images often require steady hands or support.

The Nikon features optical stabilization integrated into the lens assembly, providing more effective shake reduction, especially at the extreme telephoto end of its 20x zoom. This contributes to crisper hand-held photos in lower light or slower shutter speeds.

Hands-on experience confirmed the Nikon’s stabilization as markedly superior, enabling sharper images in scenarios where the Casio struggled.

Flash Performance and White Balance

Both cameras include built-in flashes, but their capabilities differ.

The Casio’s flash lacks detailed specs but offers typical automatic firing with limited range, controlled by standard modes. No external flash option is available.

The Nikon’s flash has a modest 5.7-meter range at auto ISO with multiple flash modes. It doesn't support external flashes either, but thanks to its more modern circuitry, it offers better exposure balance under mixed lighting.

Both cameras allow custom white balance settings, but the Nikon also supports white balance bracketing - useful for challenging lighting - giving an edge in controlled color reproduction.

Video Capabilities - Beyond Stills

If video is in your workflow, knowing each camera’s recording specs helps.

The Casio EX-Z270 offers 720p HD video at 24 frames per second in Motion JPEG (MJPEG) format, a codec resulting in larger files and lower compression efficiency. No microphone input is provided, and the lack of higher resolution or frame rate options limits creative flexibility.

The Nikon S7000 steps up to full HD 1080p recording with frame rates including 60i, 50i, and 30p. It records in MPEG-4/H.264, providing better video quality and more efficient storage. However, it lacks mic or headphone ports, so audio is fixed to the built-in mic.

From my tests, the Nikon’s video is noticeably smoother and more detailed, suitable for casual video blogging or capturing family moments, whereas the Casio’s footage looks softer and less fluid.

Battery Life and Storage - Longevity for Every Shoot

Battery endurance impacts how long you can shoot without carrying spares.

Unfortunately, the Casio EX-Z270’s official battery life is unspecified, though with its smaller sensor and simpler electronics, battery usage tends to be moderate. It utilizes the NP-80 lithium-ion battery.

The Nikon S7000 advertises a 180 shot battery life using its EN-EL19 pack - not exceptional but workable for a day out before recharge is needed.

Both cameras rely on a single SD card slot: Casio accepts SDHC and Eye-Fi wireless cards, while Nikon supports SD, SDHC, and SDXC types. The Nikon’s compatibility with SDXC allows use of larger capacity cards for longer shoots or video.

Connectivity - Modern Conveniences

In today’s world, wireless transfer and sharing put cameras at an advantage.

The Casio EX-Z270 has effectively no wireless connectivity; no Wi-Fi, Bluetooth, or NFC. Data transfer occurs solely via USB 2.0 or HDMI.

The Nikon Coolpix S7000 offers built-in wireless, including Wi-Fi and NFC for quick mobile transfers and remote control via Nikon’s SnapBridge app (though it lacks Bluetooth). This feature greatly eases photo sharing and remote shooting for the social or travel photographer.

Price vs. Performance - Where Does Value Lie?

With the Casio EX-Z270 likely found for free or very cheap in the used market and the Nikon S7000 often priced around $280 new or considerably less used, the gap in price reflects significant advances.

The Nikon delivers stronger performance, versatility, and image quality, justifying its premium. The Casio may still appeal as a backup camera or for simple snapshots when size and cost are paramount.

Take a look at these overall and genre-specific scores where the Nikon leads in most categories except absolute portability.

Genre-By-Genre Performance: Who Shines Where?

Portrait Photography

The Nikon’s higher resolution and better face detection autofocus make capturing sharp, well-exposed portraits easier. Its longer zoom also allows flattering portraits with background separation, although neither has a commandingly shallow aperture for strong bokeh.

The Casio, with its shorter focal range and limited autofocus, delivers softer portraits with less subject isolation and less precise skin tones.

Landscape Photography

For landscapes, resolution and dynamic range matter. The Nikon’s 16MP CMOS sensor coupled with its wider ISO range helps preserve highlight and shadow detail, making it the stronger landscape shooter.

Casio’s CCD sensor and smaller resolution limit sharpness and dynamic range; landscapes look softer and noisier in challenging conditions.

Neither offers weather sealing, so use caution outdoors in adverse conditions.

Wildlife Photography

Telephoto reach and autofocus speed dominate here. The Nikon’s 20x zoom and continuous AF with tracking enable you to capture distant animals better.

The Casio’s autofocus is sluggish and zoom only 4x, unsuitable for wildlife beyond close subjects.

Sports Photography

High burst rates and accurate autofocus improve success.

With no continuous shooting speed data, Casio falls short naturally. Nikon’s 9.2 fps and AF tracking allow fair action capturing but insufficient for serious sports work.

Street Photography

For discretion and portability, the Casio’s ultracompact size is ideal. It slips into pockets and is less intimidating.

The Nikon’s louder zoom and larger footprint make it less stealthy.

However, Nikon’s better low light performance handles night street scenes more successfully.

Macro Photography

The Nikon gets impressively close focusing at 1 cm, while Casio’s macro specs are unspecified and likely less capable.

Sharpness and stabilization in Nikon help achieve usable macro results.

Night and Astrophotography

High ISO performance and long shutter speeds shape capabilities.

Neither camera offers manual exposure control, limiting long-exposure astrophotography. Nikon’s ISO 6400 and better sensor improve low-light shots, but constraints remain.
