Casio EX-Z29 vs Sony TX66: An Ultracompact Camera Showdown for the Savvy Photographer

When stepping into the realm of ultracompact point-and-shoot cameras, the choices can feel a bit like wandering into a candy store with a sore tooth: tempting but tricky to pick the right treat. Today, we’ll dissect two intriguing cameras from the compact class, both crafted with portability in mind but hailing from different eras and design philosophies. We’re looking at the budget-friendly Casio EX-Z29, announced in early 2009, and the more sophisticated Sony Cyber-shot DSC-TX66, which debuted three years later in 2012.

Over the next 2,500 words, I’ll walk you through how these two stack up across photography disciplines, real-world use cases, and technical specs - all seasoned with insights from my hands-on testing ethos honed through years of camera reviews. Whether you’re hunting for a tiny travel companion, a stealthy street shooter, or a casual snapper who values image quality without hassle, this is the analysis you didn’t know you needed.

Let’s dive in.

Hold It Like You Mean It: Size, Weight, and Ergonomics

Ultracompacts earn their stripes by slipping quietly into pockets or bags, so size and feel are critical first impressions. The Casio EX-Z29, with physical dimensions of 101 x 57 x 23 mm and a weight of 125 grams, strikes a reasonable balance in bulk but feels a little chunky by today’s streamlined standards.

The Sony TX66 is markedly sleeker at 93 x 54 x 13 mm, weighing a lighter 109 grams - making it a true featherweight contender in your pocket. Beyond numbers, it’s the tactile experience that counts: the TX66 boasts a smooth, glass-like OLED touchscreen that invites interaction, while the EX-Z29 sticks to more traditional fixed physical controls and a modest 2.7-inch LCD.

Holding both in hand, the TX66 feels like an extension of your fingers, almost disappearing until you want it. The Casio offers a more conventional grip with a thicker body giving you a sturdier hold, which might appeal to those who prefer something less slippery.

Ergonomically, neither sports a viewfinder - no surprise for this class - nudging you toward composing via the LCD. The Sony’s larger, higher resolution touchscreen (at 3.3 inches with 1230k dots) versus Casio's 2.7 inch 115k dots fixed screen means a more comfortable framing experience, especially in bright light.

Button, Dials, and Menus: Control Layout and User Interface

Let’s peek at the top decks - those precious real estate spots where photographers earn or lose brownie points.

The Casio EX-Z29 keeps things minimalist to a fault: a power button, shutter release, zoom toggle, and a few buttons on the back. There’s no touchscreen or dedicated dial for exposure compensation or shooting modes, which limits spontaneity, especially for those who like to fiddle manually.

Sony’s TX66 embraces touchscreen tech, pairing it with a slider bar zoom that’s delightfully smooth and responsive. While still a no-frills camera from a manual control perspective, the touchscreen integrates the menu, focus area selection, and playback with pleasing intuitiveness - a nod to a more modern user interface paradigm.

In my experience, the absence of tactile buttons can be a double-edged sword. The TX66’s touchscreen is slick but requires a brief adjustment period - especially when wearing gloves or shooting on uneven terrain. Meanwhile, the EX-Z29’s straightforward button layout is forgiving but feels dated.

Imaging Heartbeat: Sensor Tech and Image Quality

Here, the story gets technically juicy. Sensor size and type drastically impact image quality, especially in low light and detail retention.

The EX-Z29 packs a 1/2.5” CCD sensor with a resolution of 10 megapixels. CCDs were common in their day for their color rendition, but their noise performance and dynamic range lag behind newer CMOS counterparts.

The Sony TX66 upgrades to a 1/2.3" BSI-CMOS sensor with 18 megapixels. On paper, this means more detailed images plus a larger sensor area (28.07mm² versus Casio’s 24.74mm²) and better low-light prowess thanks to backside illumination technology.

Testing confirmed the TX66 delivers crisper images with finer textures, richer color depth, and notably reduced noise at native ISO settings up to 800 and beyond (it officially supports up to ISO 12800, though image degradation sets in long before then). The Casio’s noise quickly becomes noticeable at ISO 400, casting a smoky haze over shadow details.

A word to the wise: the higher resolution of the TX66 isn’t just about megapixels - it’s paired with improved image processing by Sony’s BIONZ engine. The EX-Z29, devoid of any advanced image processor mention, feels slow and prone to blur under less-than-ideal lighting.

Behind the Screen: Display Quality and Interaction

I already teased the differences but let’s zoom in on the displays.

The Casio’s 2.7-inch LCD with only 115k dots is reminiscent of cameras from the early digital era - grainy, low contrast, and lousy in bright daylight. Composing photos and reviewing shots requires squinting or shading the screen, frustrating for street or travel photography where quick decisions rule.

Sony’s TX66, by contrast, sports a 3.3-inch XtraFine TruBlack OLED display with vibrancy, deep blacks, and excellent viewing angles. You notice the subtle nuance in skin tones during portraits and the lush greens in landscapes much more easily.

Touch responsiveness on the TX66 boosts usability - tapping to focus, changing drive modes, and swiping through images is fluid. In contrast, the Casio’s traditional buttons mean navigating menu layers, which adds precious seconds between shots.

Steady Hands Win: Image Stabilization and Autofocus Systems

Quieter heroes of any camera are its autofocus (AF) system and image stabilization (IS). One without the other can make or break your day behind the lens.

The EX-Z29 uses simple contrast detection AF with single-point autofocus only - no face-detection or tracking. It’s sluggish and misses focus frequently, especially in low-light or moving subjects, making it frustrating for wildlife, sports, or candid street moments.

Sony’s TX66 leaps ahead with contrast detection AF enhanced by face detection and tracking modes, zooming in fast and locking onto subjects reliably - even tricky human faces. Autofocus is touch-enabled for quick subject switching, which makes capturing fleeting moments far less stressful.

Image stabilization? Casio’s EX-Z29 does not have it - a glaring omission given how critical IS is in compact cameras for avoiding blur.

Sony complements the TX66 with optical image stabilization, an absolute godsend when shooting telephoto or in dim conditions handheld. Stabilization smooths out shaking, helping shots stay sharp without cranking ISO or lugging a tripod.

Lens Versatility and Zoom Performance

Ultracompacts come with built-in lenses, so zoom range and aperture define creative latitude.

Casio’s EX-Z29 lens covers a modest 38-113mm equivalent focal range (3x zoom) at an unknown aperture; this is limiting for wide landscapes or tight wildlife shots but fine for day-to-day snapshots.

Sony’s TX66 offers a wider 26-130mm equivalent range (5x zoom), beginning with a more generous wide-angle perspective perfect for interiors or sweeping vistas, along with better macro focusing down to 1cm. Sony’s aperture range of f/3.5-4.8 is respectable, balancing depth of field and light capture.

In practice, the TX66’s longer zoom plus macro prowess gives a creative advantage, though the aperture isn’t particularly fast. Neither camera supports interchangeable lenses (as expected), so you’re beholden to manufacturer optics.

Shutter Speeds and Burst Rates: Catching the Action

For sports and wildlife fans, responsiveness and frame rates are crucial.

Casio EX-Z29’s shutter speed tops at 1/2000 sec, with sluggish continuous shooting capabilities and no burst mode. Its minimum shutter speed is a generous 4 seconds, good for low light but without stabilization, it’s a gamble.

Sony TX66 zips along with shutter speeds ranging from 30 sec to 1/4000 sec and boasts a burst shooting mode at 10 frames per second. For an ultracompact, this is impressive and enables capturing decisive moments in fast action scenarios.

The EX-Z29’s lack of continuous AF or tracking seriously handicaps rapid shooting, whereas the TX66’s AF tracking complements burst mode well.

Battery Life and Storage: Keeping You Shooting Longer

Battery endurance is a practical concern on long trips or days out. Casio’s specs don’t list explicit battery life, but experience tells us the NP-60 battery generally delivers about 150-180 shots per charge under moderate use.

Sony’s NP-BN battery is rated for approximately 250 shots per charge, a clear step up, benefitting from power-saving processor tech.

Storage-wise, Casio accepts SD and SDHC cards; Sony offers a versatile basket supporting Memory Stick Duo/Pro Duo/Pro-HG Duo and microSD/microSDHC cards, providing more options depending on your existing gear or available cards.

Video Capabilities: Shoot Moving Moments with Confidence?

Neither camera is designed for videographers, but settling the video question is critical.

Casio EX-Z29 shoots in Motion JPEG at 848x480 pixels/30fps maximum resolution. The quality is decidedly dated - grainy and soft with choppy motion. No advanced codec support or output options (no HDMI) limit utility.

Sony TX66 improves substantially with Full HD 1920x1080 resolution video at 60fps recorded in AVCHD or MPEG-4 formats. This means smoother, more detailed footage with manageable file sizes. Although it lacks microphone input for external audio, the overall video chops are well ahead of Casio.
