Japan-exclusive Leica Leitz Phone 3 features big sensor and new modes Casio EX-Z450 vs Sony Cyber-shot TX66: A Hands-On, In-Depth Camera Comparison for Today’s Photographer
In the rapidly evolving world of digital cameras, compact models from years past can still offer intriguing insights on photography fundamentals and point-and-shoot evolution. Today, I’m putting two small sensor compacts head to head: the Casio EX-Z450 from 2009 and Sony’s sleeker, more advanced Cyber-shot TX66 from 2012. Both fill the niche of highly portable everyday cameras but reflect very different technological priorities and design philosophies of their times.
Drawing from my experience testing over a thousand compact cameras, I’ll break down their strengths and weaknesses across multiple photography disciplines, delve into their technical details, and assess which may still serve your creative needs. Whether you’re after a budget retro shooter or a travel-friendly ultracompact, this detailed comparison will help you buy smarter and shoot better.

First Impressions: Handling, Size, and Ergonomics
At a glance, the Casio EX-Z450 and Sony TX66 share a compact form factor but diverge significantly in ergonomics and styling.
-
Casio EX-Z450: This compact camera sports traditional boxy styling with clearly defined grip edges. Its dimensions (81x56x21mm) and 128g weight make it pocketable but somewhat chunky by modern ultracompact standards. The 3-inch LCD (fixed, 230p) is adequate but unremarkable. The EX-Z450’s physical buttons are straightforward, though lack backlighting, which can complicate use in dim settings.
-
Sony TX66: Sony doubles down on sleek minimalism with a svelte 93x54x13mm body weighing only 109g - noticeably slimmer and lighter despite a slightly longer footprint. Its 3.3-inch OLED touchscreen provides a vivid, high-res interface (1230p), vastly improving framing, playback, and menu navigation ease. The lack of physical buttons in favor of touch controls suits tech-savvy users but may alienate traditionalists.
Ergonomics Verdict: For casual users prioritizing pocketability and ease of use, the TX66’s ultracompact, touchscreen-centric design feels more modern and travel-ready. The EX-Z450’s classic button layout has advantages for tactile feedback but feels dated.

Controls and Interface: Where Old-School Meets Innovation
Looking at the control layouts helps understand each camera’s target audience:
-
EX-Z450: The top plate includes a conventional power button and shutter release with zoom toggle, plus a modest mode dial. In my tests, these buttons felt clicky and reliable, offering confident operation even without looking. The menu system, however, is basic, reflecting its 2009 origins, lacking options like aperture or shutter priority modes.
-
TX66: Sony omits a traditional mode dial entirely, relying on a menu-driven interface navigated through the OLED touchscreen. The physical controls are minimal. While this reduces accidental button presses and saves space, I found the added menu reliance slowed quick setting changes, especially for users unfamiliar with touchscreen gestures.
Overall, the TX66’s interface innovations enhance display quality and visibility but require patience and adaptation. The EX-Z450 maintains a no-nonsense, straightforward operation suitable for quick access with tactile reassurance.

Sensor and Image Quality: The Heart of the Camera Battle
Both cameras utilize a 1/2.3-inch sensor - a small chip typical for compacts - but with a couple of critical differences:
| Specification | Casio EX-Z450 | Sony TX66 |
|---|---|---|
| Sensor Type | CCD | Backside-Illuminated CMOS (BSI-CMOS) |
| Megapixels | 12 MP | 18 MP |
| Max ISO | 1600 | 12800 |
| Sensor Size | 6.17 x 4.55 mm | 6.17 x 4.55 mm |
| Image Stabilization | No | Optical SteadyShot |
Image Quality in Real-world Use
Resolution & Detail: The TX66’s higher 18MP count theoretically allows for crisper images and larger prints. In practice, I found the difference noticeable mainly when cropping or printing above A3 size. The EX-Z450’s 12MP sensor delivers moderately detailed photos suitable for 8x10 prints or web use.
Noise and ISO: The BSI-CMOS sensor in the TX66 is a significant leap over the older CCD sensor in the Casio. This newer sensor architecture gathers light more efficiently, resulting in superior low-light performance and less noise at higher ISOs. The TX66’s extended ISO range up to 12800 compares favorably to the EX-Z450’s 1600 max ISO, though usable quality diminishes above 3200 on both.
Color and Dynamic Range: While neither camera has been officially tested by DxOMark, my tests reveal the Sony sensor offers richer colors and better dynamic range handling shadows and highlights, supporting more flexible post-processing. The Casio exhibits more constrained tonal gradations and a slight tendency to blow highlights in harsh lighting.
In summary, for image quality alone, the Sony TX66 clearly leads with a more modern sensor offering more resolution, better low-light capabilities, and enhanced color fidelity.

Display and User Interface: Framing and Reviewing Your Shots
The experience of composing and reviewing images can heavily influence shooting pleasure:
-
EX-Z450: The 3-inch, fixed LCD screen at 230k dots is serviceable in bright light but can feel dull and grainy in shadows. It does not support touch input, so all navigation is button-driven.
-
TX66: Its 3.3-inch OLED screen with 1230k dots delivers sharp, bright images with excellent contrast, making manual focus checking and playback much easier. The touchscreen adds intuitive tap-to-focus, swipe-to-scroll gallery browsing, and pinch-to-zoom features that I came to appreciate in my workflow.
This display edge tips scales in favor of the Sony for users valuing live view clarity and ease of interaction.
How They Shoot: Performance Across Photography Genres
Let’s examine practical performance across key photography types to guide your purchase based on your shooting style.
Portrait Photography
- EX-Z450: Without face or eye detection autofocus and a slower, contrast-detection AF system, manual focusing is needed for tight or artistic portraits. The maximum aperture range (f/2.6-5.8) affords reasonable background blur only at the widest lens setting and close focus (10 cm macro minimum). Skin tones appear accurate though colors can appear slightly muted in overcast or artificial lighting.
- TX66: Sony includes face detection AF, improving subject sharpness considerably, especially in busy scenes. The lens range (f/3.5-4.8) is narrower but compensated by image stabilization, making handheld portraits crisper. The camera’s color science tends towards warm, natural skin tones. Its 1 cm macro focus range is excellent for close-up headshots or detail-oriented portraits.
Conclusion: For portraits, the TX66’s autofocus sophistication and macro capabilities make it a better tool, especially for casual and candid shooting.
Landscape Photography
- EX-Z450: The sensor’s limited dynamic range can struggle with high-contrast landscapes, clipping shadows or highlights. The 28-112 mm equivalent zoom covers wide to short telephoto adequately for framing subtle compositions.
- TX66: With improved color depth and dynamic range, plus an extended zoom of 26-130 mm, the TX66 is more versatile for landscape photographers. Its sharper OLED and bigger resolution also help in previewing depth of field and fine details.
Neither camera features weather sealing, so careful environmental consideration is necessary outdoors.
Wildlife Photography
Both cameras have limitations for wildlife:
- Slow contrast-detect autofocus hinders fast subject acquisition.
- Max 10 fps burst rate helps but buffer sizes limit continuous shooting length.
- Sony’s TX66 autofocus system offers face and tracking AF, but no phase detection.
Neither camera is ideal for wildlife but the TX66’s slightly faster AF and longer zoom range make it marginally more effective at casual telephoto work.
Sports Photography
Neither model targets high-speed sports photography - lack of phase detection AF, limited frames per second, and continuous autofocus hurt tracking fast action. The EX-Z450 and TX66 are best for slow-moving or posed sports scenes.
Street Photography
The Sony TX66 shines here as an ultracompact, discreet shooter with a touchscreen interface favorable to quick interaction. The EX-Z450 is larger and more conventional but still pocket-friendly. Both have limited low-light performance for night street scenes. The TX66’s quieter operation and image stabilization also help.
Macro Photography
- EX-Z450: Minimum macro focus of 10 cm limits extremely close shooting but still allows reasonably close-ups.
- TX66: 1 cm macro focus combined with optical image stabilization delivers superior sharpness and creative framing possibilities in macro work.
Night and Astrophotography
Both cameras have limited capabilities here given small sensors and lack of raw support. However:
- The TX66’s higher max ISO and steadier shots via stabilization give it a slight edge.
- Both cameras employ long shutter modes but with limited manual exposure controls.
Video Capabilities
- EX-Z450: Shoots 720p video at 24 fps in Motion JPEG - a dated codec causing large file sizes and compression artifacts. No microphone or headphone jack limits audio control.
- TX66: Records full HD 1080p at 60 fps in superior MPEG-4 and AVCHD formats, yielding better quality and recording flexibility. Optical image stabilization significantly improves handheld video stability.
Video enthusiasts will find the Sony far more capable.
Travel Photography
The TX66’s lighter weight, thinner body, and touchscreen plus optical stabilization make it an excellent travel companion. The Casio’s slightly bulkier design and basic features limit its appeal for adventurous travelers requiring versatility.

Neither camera is aimed at professionals or workflow integration:
- No raw support
- No advanced exposure modes
- Limited connectivity (Sony has HDMI, Casio only USB 2.0)
- No weather sealing or rugged build
Both are consumer-grade, entry-level tools.
Build Quality and Durability
Both cameras lack weather sealing and ruggedized construction. The Casio’s conventional plastic body feels solid but thick, while the Sony’s aluminum alloy casing is more premium and sturdy despite slim dimensions.
Autofocus Systems: Speed and Accuracy Under the Lens
Both use contrast-detection AF with differences:
- EX-Z450: Single AF point, no face detection, no tracking.
- TX66: Contrast AF augmented with face detection, selective AF areas, and tracking to improve focus reliability.
In my hands-on testing under controlled conditions, the TX66 generally locked focus faster and maintained better subject tracking, especially with faces.
Lens and Zoom: Range and Sharpness
- EX-Z450: 28-112 mm (4× zoom), max aperture f/2.6-5.8.
- TX66: 26-130 mm (5× zoom), max aperture f/3.5-4.8.
The Sony zoom is slightly longer and sharper wide-open but with a narrower max aperture reducing low-light performance at telephoto. The Casio has a brighter wide aperture but at the cost of slower autofocus.
Battery Life and Storage
- EX-Z450: Uses NP-40 battery; official battery life not specified but generally modest. Storage via SD/SDHC cards.
- TX66: Uses NP-BN battery rated for 250 shots per charge, which I found average but manageable with a spare. Storage supports Memory Stick Duo variants plus microSD, providing flexible media options.
