Casio EX-Z29 vs Sony W320: A Deep Dive into Two Ultracompacts from the Late 2000s

When you start poking around the vintage ultracompact cameras circa late 2000s, the market was filled with enigmatic models vying for your pocket and your wallet. Today, I’m turning the spotlight on two distinct contenders: the Casio EX-Z29 and the Sony Cyber-shot DSC-W320 (hereafter “Sony W320”). Both occupy that niche ultracompact category but cater to quite different user expectations when you zoom beyond marketing buzzwords.

Having personally handled and tested thousands of cameras of every stripe, I’m going to unpack these two pocket cameras from multiple angles. We’ll look at their real-world usability across photo genres, technical merits, ergonomics, sensor performance, and even value proposition - no stone unturned. Ready to geek out on some classic pocket digicams? Let’s dig in.

The Ultracompact Physical Showdown: Size, Weight, and Handling

Ultracompacts aim to slip easily into pockets and avoid causing any wrist strain by the end of a day’s shooting. Neither of these models were heavyweights - far from it.

The Casio EX-Z29 measures roughly 101 x 57 x 23 mm and weighs about 125 grams. The Sony W320, slightly more petite at 93 x 52 x 17 mm and 117 grams, puts a good inch less on every dimension and shaves off a few grams. This Sony’s slightly slimmer body lends itself better to discreet street photography or travel scenarios where every millimeter counts.

Both cameras lack the grip protrusions that make larger compacts more comfortable in hand, so the smaller, slimmer Sony does feel less awkward to grasp for extended periods.

Those figures don’t tell the full ergonomic tale - you’ll notice the difference in button layout and top controls in the next section, which impacts how quickly you can operate the camera spontaneously (spoiler: Sony’s layout feels a bit more polished).

Design Elegance and Usability: The Top-Down View on Control Layout

The user interface and physical controls on ultracompacts often make or break their usability since menus alone can be clunky during fast shooting.

Here’s the top view of both cameras for a hands-on perspective:

Sony W320 shines here with a more balanced button placement and inclusion of a zoom lever around the shutter button, supporting intuitive framing adjustments without awkward hand shifts. Meanwhile, Casio’s EX-Z29 has a simpler, somewhat sparse control layout. This minimalism might frustrate enthusiasts wanting quick access to exposure compensation or mode dials - which, spoiler alert, neither offers.

Neither camera supports manual exposure modes or shutter/aperture priority - so you’re firmly in auto or program territory, which can be a sticking point for enthusiasts used to more control. However, the Sony edges out slightly by including a selective autofocus mode with multiple focus points, making it easier to lock focus on your preferred subject rather than relying on fixed-center focus.

Sensor Specs and Image Quality Battle: The Heart of Each Camera

Here’s where the rubber meets the road - sensor technology and resulting image quality.

• Casio EX-Z29 packs a 1/2.5-inch CCD sensor measuring about 5.74 x 4.30 mm with 10 megapixels and a 3x optical zoom lens covering roughly 38-113 mm (35mm equivalent). The sensor area is about 24.74 mm², which is quite small compared to modern standards, and the lens is modest but sharp for casual snapshots.

• Sony W320 uses a slightly larger 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm, 14 megapixels, and a wider 4x zoom lens from 26-105 mm equivalent, aperture f/2.7-5.7. This sensor area of about 28.07 mm² combined with the higher pixel count gives it a technical edge in resolution and potentially better detail retention.

In practical terms, the Sony’s smaller minimum focal length (26 mm vs. Casio’s 38 mm equivalent) means wider framing without cropping - handy in tight interiors or landscapes. The Casio’s lens doesn’t open particularly wide, limiting low-light performance and depth-of-field control.

Now, I must caveat here: neither camera shoots RAW or offers extensive manual controls, which is typical for early ultracompacts but a notable limitation for those seeking creative flexibility or post-processing latitude.

Viewing and Interface: Reliability Beyond the Viewfinder

With no electronic viewfinders on either camera - typical for their class in that period - the rear LCD becomes your eye.

Both models offer 2.7-inch fixed LCD screens, but here the Sony W320 boasts double the resolution (230k vs. Casio’s paltry 115k dots), translating to a sharper, more detailed live view and review experience.

From personal experience, a clearer screen makes a surprisingly big difference - not just for composing but for verifying critical focus and exposure. The Casio’s duller display feels frustratingly coarse, particularly in bright sunlight.

Neither camera offers touchscreen interfaces, which is no surprise at their release dates but perhaps a mild inconvenience by today’s standards.

Still Images and Video: What Do These Cameras Capture?

Let’s look at the core deliverables - photos and video.

With maximum resolutions of 10 MP (Casio) versus 14 MP (Sony), the Sony gives you bigger image files with finer detail potential. This reflects in sample images I grabbed during field tests.

Here’s a gallery of sample shots - set exposure to auto and handheld:

Portraits: Both cameras struggle with bokeh due to their small sensors and relatively high f-numbers at the telephoto end. Eye detection or face priority AF is nowhere to be found. The Sony’s autofocus with multiple AF points is more reliable locking focus on faces, which helps avert typical early fixed-point focusing miss-shots. Skin tone reproduction is neutral on both, though the Sony tends to render slightly warmer tones, which some may prefer for casual portraiture.

Landscape: The Sony's wider lens (26 mm vs. 38 mm) and higher resolution give more framing flexibility and better detail preservation in landscape scenarios. Both cameras exhibit limited dynamic range, with highlights prone to blowing out and shadows losing detail in high contrast scenes - typical for small CCD sensors lacking HDR features.

Video: Neither camera is a video powerhouse. Both max out at 640x480 resolution at 30 fps, encoded in Motion JPEG - a format notorious for bulky file sizes and low compression efficiency. Serious video shooters will instantly unlock new iPhones or entry-level DSLRs instead, but as grab-and-go casual options, they suffice.

Autofocus Performance and Burst Shooting: Speed & Accuracy in the Field

Autofocus (AF) often defines user satisfaction but is an area where basic ultracompacts historically stuttered.

The Casio EX-Z29 uses contrast-detection AF with a single, fixed focus point - meaning if your subject isn’t near the center, good luck. There’s no tracking or face detection. Focus speed can also feel sluggish, especially in low light.

The Sony W320, while still contrast-detection based, offers nine focus points with center-weighted and multi-area AF options. It lacks face detection, but the additional points translate into faster locking and less hunting in decent light.

Neither camera supports continuous autofocus during burst shots.

Speaking of bursts, both cameras are underwhelming here - Sony claims about 1 frame per second continuous shooting speed, more a modest snap-them-one-after-another scenario than serious action work.

Construction and Weather Sealing: The Durability Check

Both cameras share similar construction quality typical for affordable ultracompacts of their day - plastic bodies with no significant weather or shock sealing.

Neither cameras are waterproof, dustproof, freezeproof, or crushproof - meaning you’ll want to keep them out of harsh environments.

If durability is a priority for rugged fieldwork, neither camera ranks high here.

Battery Life and Storage: How Many Shots Can You Take on the Road?

Both use proprietary lithium-ion batteries: Casio’s NP-60 and Sony’s NP-BN1 models. Unfortunately, official CIPA ratings for battery life are absent. From personal use and general experience with cameras of this generation, you can expect around 150-200 shots per charge under average use.

Both cameras accept SDHC memory cards, but Sony supports Memory Stick Duo variants as well - adding flexible storage options back in the day.

Connectivity and Modern Features: Wireless and Ports

In connectivity, the Casio offers Eye-Fi compatibility, which allowed wireless photo transfer via special SD cards before Wi-Fi became ubiquitous - a neat early innovation but largely obsolete now.

Sony lacks wireless transfer, but benefits from an HDMI port for direct TV connection.

Both cameras carry USB 2.0 for data transfer, but no microphone or headphone jacks for video work.

So, Which Camera Dominates? Overall Ratings and Performance Analysis

To synthesize the above findings, here’s a comparative performance rating I developed based on field tests, handling, and image quality:

Sony W320 leads comfortably in image resolution, autofocus capability, user interface, and video output, making it the more versatile of the two. Casio EX-Z29 holds its own as a simple point-and-shoot for ultra-budget buyers needing no-frills snapshots.

Specialized Photography Disciplines: Who Fits Which Niche?

While both cameras are consumer-grade compacts, it’s useful to consider their fit for specific photographic genres:

• Portrait Photography: Sony edges ahead due to wider zoom range and better AF flexibility, though neither model can deliver creamy bokeh or eye detection.

• Landscape Photography: Sony’s wider angle and higher resolution again pay dividends.

• Wildlife Photography: Neither is fit for long-range telephoto or fast AF required - small sensor and zoom optically limited.

• Sports Photography: Burst rates too slow, autofocus too basic for action.

• Street Photography: Sony’s compactness is a virtue, with discrete size and faster autofocus, suitable for quick candid shots.

• Macro Photography: Sony’s 4 cm closest focus beats the Casio’s more conventional macro capabilities.

• Night/Astro Photography: Both falter due to small sensors and limited ISO ranges; no long exposure controls.

• Video Capabilities: Both provide VGA resolution video only; Sony holds a slight edge with HDMI output.

• Travel Photography: Sony’s smaller size, better zoom range, and higher image quality win here.

• Professional Work: Neither camera meets pro needs for RAW, manual control, weather sealing, or compatible lenses.

Final Verdict: Who Should Buy Which Camera?

For budget-conscious beginners or absolute casual shooters, the Casio EX-Z29 offers decent automatic shooting in a simple package for around $80 used today. It’s good for snapshots in well-lit environments but lacks modern usability comforts.

For enthusiasts seeking greater image quality, wider zoom flexibility, better autofocus, and a sharper screen, the Sony W320, with an approximate used price around $270, is the clear choice. It’s a more polished ultracompact with features offering a tangible upgrade in many scenarios.

Still, both cameras represent an era when ultracompacts were in rapid transition - pre-smartphone domination but pre-mirrorless sophistication. For anyone serious about photography beyond casual memory keeping, investing in more modern equipment is well worth it.

Reflecting on Ultracompacts Then and Now

Handling the Casio EX-Z29 and Sony W320 reminds me how far camera technology has advanced in just over a decade. Today’s smartphones deliver higher-resolution images in more varied lighting with computational magic, while entry-level mirrorless cameras afford the creativity and control.

Yet, there’s nostalgic charm in these classic ultracompacts - simple, point-and-shoot machines that let you concentrate on framing and timing rather than settings menus. They were gateways for many into the photographic world.

If you have the chance, try shooting with both and enjoy the quirks each brings. Just don’t expect miracles for wildlife or sports. For casual use, either will provide smiles - if not spectacular images.

Happy shooting and informed choosing!
