Comparing the Casio EX-Z90 and Nikon Coolpix P340: A Tale of Two Compacts for Enthusiasts

In the ever-evolving compact camera market, two contenders from different generations stand out for curious photographers exploring small sensor compacts: the Casio EX-Z90, released in 2009, and the Nikon Coolpix P340, launched half a decade later in 2014. At first glance, these cameras appear aimed at similar audiences - travelers, casual shooters, and enthusiasts wanting an easy-to-carry camera with some creative control. However, beneath their petite exteriors lie widely different technologies and performance capabilities that can significantly affect your shooting experience and image quality.

Having spent extensive hands-on hours testing these cameras across varied conditions, this article dives deep into their technical underpinnings, practical performance, and value proposition. Whether you’re after a trusty backup to a larger system, a pocketable travel companion, or a first step into manual controls, read on to unpack which compact better matches your photographic ambitions.

Taking Stock: Size, Handling, and Ergonomics

Before zooming into image quality and specs, the physical interaction with a camera often dictates whether it will become your favorite companion or just another gadget gathering dust. The Casio EX-Z90 and Nikon P340 represent distinct design philosophies almost a generation apart.

The Casio EX-Z90 boasts a notably slim and lightweight profile - only 90×52×19 mm and weighing 121 grams. It slips easily into a jacket pocket without notice, making it ideal for minimalists who prize convenience above all else. However, its narrow body and flat grip leave something to be desired in terms of physical comfort and stability during shooting, especially when using longer focal lengths.

By contrast, the Nikon P340 is larger and chunkier at 103×58×32 mm and 194 grams but feels substantially more purposeful in hand. The modestly extended grip area gives a reassuring hold, crucial during longer sessions or when tracking fast-moving subjects. At its higher price point, Nikon clearly invested in crafting a camera that supports longer creative interactions without hand fatigue.

Moving up to the top plates reveals a contrasting control layout between the two:

The Casio offers a simplified control scheme aimed at snap shooters - few dedicated dials, mostly relying on menus and buttons. Meanwhile, the Nikon incorporates dedicated mode dials, a rear command dial, and direct access to exposure compensation and shutter/aperture controls. For photographers who appreciate tactile feedback and quick adjustments without delving deep into menus, the P340’s design aids responsiveness and creative freedom.

Sensor Technology and Image Quality: Size Matters

Arguably the most critical determinant of image quality in compact cameras is the sensor - size, resolution, and underlying technology influence sharpness, noise, and dynamic range.

Both cameras stick to the 12MP resolution sweet spot, but the sensor sizes and types diverge considerably. The Casio EX-Z90 employs a 1/2.3" CCD sensor, measuring approximately 6.17×4.55 mm (28.07 mm²). In contrast, the Nikon P340 sports a larger 1/1.7" BSI-CMOS sensor at 7.44×5.58 mm (41.52 mm²). This seemingly minor jump in dimensions equates to roughly 50% more surface area gathering light.

What does this mean practically? The larger, backside-illuminated CMOS sensor of the P340 provides several advantages:

• Improved low-light performance with less noise and smoother tonal gradations
• Better dynamic range, preserving highlight and shadow details
• Higher native ISO ceiling (6400 vs. 1600) to maintain usable exposures in challenging conditions

The Casio’s older CCD technology struggles significantly as ISO climbs beyond 400, accompanied by visible grain and color degradation. Moreover, the smaller sensor limits depth of field control and low-light capability - factors that impact disciplines like portraiture and night photography.

Visual Experience: LCD Screens and Viewfinding

Because neither camera features an electronic viewfinder - a common omission in compact models - the LCD screen forms the primary framing and review interface.

The Casio EX-Z90 features a modest 2.7" fixed, non-touch LCD with a low 230k-dot resolution. Colors appear muted, and visibility under bright sunlight often presents a struggle. The absence of touchscreen input makes menu navigation slower and less intuitive.

The Nikon P340 counters this with a larger 3.0" TFT LCD at a much higher resolution of 921k dots. While non-touch, the screen’s clarity and brightness contribute to a more pleasant composing and reviewing experience. This difference is appreciable when evaluating images on location, especially given the P340’s improved sensor detail.

Both lack eye-level or electronic viewfinders, meaning outdoor photographers working in bright conditions may find framing challenging unless relying on an optional accessory or external monitor.

Practical Autonomy and Storage

Battery life and storage flexibility often get overlooked but can make or break an outing.

• Casio EX-Z90 uses an NP-60 rechargeable battery; official manufacturer life specs are unavailable. In practical tests, expect a modest frame count per charge (circa 150-200 shots), partly due to older wireless transfer features like Eye-Fi card compatibility, which, while innovative for its time, came clunky and was soon abandoned in favor of built-in Wi-Fi in newer cameras.

• Nikon P340 runs on an EN-EL12 battery and advertises approximately 220 shots per charge - typical for cameras in this category. It supports standard SD/SDHC/SDXC cards, allowing ample storage flexibility.

Connectivity-wise, the Casio relies on USB 2.0 and Eye-Fi compatibility, whereas the Nikon improves with built-in Wi-Fi and HDMI output - a boon for quick transfers and external display use.

Zoom Range, Aperture, and Lens Characteristics

Lens performance impacts sharpness, bokeh quality, and creative framing versatility.

The Nikon’s wider 24mm equivalent ultra-wide starting point dramatically increases compositional flexibility for landscapes, street scenes, and architecture. More impressively, the bright f/1.8 max aperture at the wide end facilitates shallow depth of field, superior low-light capture, and more pleasing bokeh - qualities the Casio cannot match with its f/3.1 at the wide end.

The Casio’s macro capability, at a minimum focus distance of 10 cm, is serviceable but does not offer the close-to-subject intimacy delivered by Nikon’s 2 cm macro range, which opens possibilities for detailed nature and product photography.

The lack of any image stabilization on the Casio limits steady handheld shooting, especially toward the telephoto end. The Nikon’s optical stabilization compensates well for small shakes and enables slower shutter speeds when the light dims.

Autofocus and Manual Controls: Where Control Meets Speed

Autofocus systems have matured considerably between these two cameras’ release dates.

• The Casio EX-Z90 uses contrast-detection AF only, with no face or tracking modes. There is no continuous autofocus; manual focus is available but limited in precision due to coarse adjustment steps and lack of focus aids.

• The Nikon P340 employs a more sophisticated contrast-detection AF incorporating face detection and tracking capabilities, benefitting fast-moving subjects and portraits. The presence of manual focus with a rear dial facilitates more deliberate focusing.

Exposure modes markedly contrast as well: the Casio offers no aperture or shutter priority, nor manual exposure modes, limiting creative control for enthusiasts. The Nikon includes full manual exposure, aperture priority, shutter priority, and exposure compensation, catering to photographers who want to shape images more thoughtfully.
