Casio EX-S12 vs Panasonic LX5: The Compact Camera Duel That Defines Value and Versatility

In the realm of compact cameras, where pocketability often punches above specs, choosing the right model can be as tricky as nailing sharp focus in low light. Today, I’m diving deep into two contenders separated by a couple of years but united by the small sensor compact category: the budget-friendly Casio EX-S12 announced in early 2009, and the feature-rich Panasonic LX5 launched towards the close of 2011. Both appeal to photography enthusiasts seeking a lightweight, easy-to-carry camera with better image quality than your average smartphone - but which one holds up under serious scrutiny?

Having put both through their paces in the studio and in the wild, this comprehensive comparison highlights what each camera brings to the table for different photography disciplines, along with hard-hitting technical analysis. Grab a coffee, maybe your favorite lens, and let’s unpack this compact camera showdown.

Taking the Cameras in Hand: Size, Ergonomics and Design

Before clacking off shots, you want a camera that feels natural in your grips, intuitively arranged buttons, and ideally, doesn’t scream “amateur” when you pull it out in public.

Let’s talk measurements first, and I’m showing this side-by-side so the scale sinks in clearly.

The Casio EX-S12 boasts a slender, almost pocket-friendly 95 x 60 x 23 mm body weighing in at a featherweight 111 grams (without battery). It’s minimalist to a fault - no viewfinder, rear screen is fairly modest at 2.7 inches with a low-resolution 230k dots.

On the other hand, the Panasonic LX5 is chunkier: 110 x 65 x 43 mm and 271 grams, more than double the weight. It favors photographic control over slimness. The ergonomics are well thought out, with a pinch of a retro aesthetic, and a comparatively roomy 3-inch LCD screen sporting 460k dots. The LX5 also offers an optional electronic viewfinder (an add-on, mind you), appealing to those craving traditional composition tools - a clear advantage for enthusiasts who prefer shooting with their eye to the viewfinder.

Looking down at the top plates, the LX5 presents a more serious control setup - shutter speed dial, PASM (Program, Aperture, Shutter, Manual) modes, and customizable buttons. The EX-S12 sacrifices manual modes entirely, offering only a basic exposure compensation and no shutter or aperture priority. In my testing, this meant that alongside casual snapshots, creative exposure control was impossible on the Casio.

Ergonomics verdict: If you’re after quick grab-and-go ease, the EX-S12 wins hearts. But for photographers who want some creative control without lugging a DSLR, the LX5’s design is leagues ahead.

The Heart of Image Quality: Sensor and Optics

If you’re after good photos beyond point-and-shoot snapshots, sensor size and lens quality usually make or break the deal.

Both cameras sport CCD sensors, but the Panasonic LX5’s sensor is significantly larger at 1/1.63” (about 44.87 mm²) compared to the Casio EX-S12’s 1/2.3” (28.07 mm²). That difference translates to improved light gathering capability, better noise control, and richer colors on the LX5. While neither sensor matches APS-C or full-frame beasts, the LX5’s larger sensor pushes the image quality needle forward noticeably.

As for resolution, the Casio offers 12MP (4000 x 3000) while the Panasonic stands at 10MP (3648 x 2736). You might assume the Casio’s higher megapixels mean sharper shots - but in reality, bigger pixels on the LX5 generally deliver cleaner low light performance and better dynamic range. Raw support on the LX5 gives another leg up for serious post-processing, whereas the Casio offers only JPEG output.

Lens-wise, the LX5 sports a versatile Leica-branded 24-90mm equivalent with a bright F2.0-3.3 aperture. This wide aperture facilitates superior low light capture and creamy backgrounds. The Casio’s 36-108mm (F2.8-7.9) lens starts narrower and gets noticeably darker when zooming, limiting its shallow depth-of-field capabilities.

The LX5’s macro focus distance is an impressive 1cm, which combined with precise manual focusing, shines in close-up scenarios. The Casio doesn’t specify macro range and lacks manual focus control, which constrains creative shot composition.

Taken together, the Panasonic LX5 offers a larger sensor and brighter, sharper optics - essential for photographers serious about image quality.

Real-World Shooting: Focusing and Exposure

A key consideration for enthusiasts is how quickly and accurately a camera locks focus, especially in varied lighting and subject conditions.

Both cameras rely on contrast-detection autofocus systems without phase detection, but the LX5 boasts 23 focus points versus Casio’s unspecified single center-weighted AF point.

The Casio EX-S12’s focusing speed is acceptable in daylight but noticeably slow in dimmer conditions and prone to hunting. Its lack of continuous autofocus and tracking makes it a poor choice for moving subjects.

Conversely, the Panasonic LX5 offers snappy single AF and manual focus rings that lend control and speed. In my field tests involving street and portrait work, the LX5 locked focus quickly, allowing me to catch fleeting expressions without digital frustration.

Neither model offers face detection or advanced AI-driven autofocus, which today’s cameras often pack. But the LX5’s higher AF point count and manual override provide more dependable exposure control and framing precision.

For exposure, the LX5 supports shutter and aperture priority and full manual modes, plus exposure compensation, empowering photographers to shape their images dramatically. The Casio EX-S12’s restricted exposure modes make it much less flexible.

Display and Interface: Your Window to the World

A useful LCD screen is invaluable for image composition and review, especially in bright outdoor conditions.

On paper, the LX5’s 3-inch, 460k-dot LCD screen is nearly twice as sharp as the Casio’s 2.7-inch 230k. During real-world usage, the LX5’s display delivered more accurate previews and better visibility under sunlight. The interface menus were thoughtfully organized, with direct access to critical settings and the option to toggle grid lines, histogram, and highlight warnings.

Sadly, neither camera offers a touchscreen interface, which feels a little archaic by modern standards, and the Casio’s interface felt basic and less responsive.

Outdoor Durability and Handling in the Field

Neither camera is weather-sealed, splash-proof, or ruggedized to any significant degree, which restricts their use in harsher conditions out of the box.

However, the Panasonic LX5’s more substantial build and grip provide a better feel when shooting outdoors for extended sessions, while the Casio, being ultralight, invites a more ephemeral use-case - a casual snap-and-go but not a trusty daily companion under rigorous shooting conditions.

Battery life details are sparse in specs, but based on long-term use, the smaller battery and compact size of the Casio tend to demand frequent changes or spare batteries for longer shoots, whereas the LX5 holds up better, befitting its enthusiast-level intent.

Multi-Discipline Shooting: Which Excels Where?

Let’s break down their performance across photographic genres with a mix of technical notes and field experience. I’ve also included sample images so you can see each camera’s character in action.

Portrait Photography

Portraits demand beautiful skin tones and smooth bokeh. The LX5’s fast F2.0 lens at 24mm and ability to shoot raw give portraits a warmth and detail the Casio can’t match. The Casio’s narrower zoom range and no raw output limit post-processing options and subtle tonal rendition.

Neither offers face or eye detection autofocus, meaning you have to be more patient and attentive when focusing, which is fine for deliberate portraits but less so with moving subjects.

Landscape Photography

For landscapes, resolution and dynamic range reign supreme. Thanks to its slightly larger sensor and respectable dynamic range score, the LX5 produces richer color gradations and better shadow detail.

The Casio’s 12MP sensor seems promising on paper, but pixel size and lens diffraction slightly blunt its peak sharpness. Neither model is weather-sealed, so caution is needed when shooting outdoors in inclement weather.

Wildlife and Sports Photography

Burst rates and tracking AF define success here. The LX5 provides a modest continuous shooting rate (3 fps) with no tracking autofocus, making it suitable only for slow action or casual wildlife shots. The Casio lacks continuous AF entirely and doesn’t list a burst shooting mode.

Neither are designed for fast sports, so if shooting erratic movement is your thing, better look elsewhere.

Street Photography

Discretion and portability favor the Casio - ultra-light, quiet, and pocket-friendly. The LX5’s more substantial size and shutter noise make it less subtle but it rewards with superior image quality and manual control.

Low light street shooting benefits from LX5’s wider aperture and higher ISO ceiling, though autofocus can struggle in very dim scenes.

Macro Photography

The LX5 shines with a 1cm minimum focus distance and manual focus ring - ideal for detailed close-ups and experimentation. The Casio’s lack of macro specs and manual focus limit opportunities here.

Night and Astrophotography

Neither is perfect for astrophotography, but LX5’s higher ISO capability and raw support deliver cleaner results in night scenes with available light. Casio’s max ISO of 1600 and limited sensor size restrict image quality in this realm.

Video Capabilities: The Moving Picture Section

Both cameras shoot HD video but with differing approaches.

• Casio EX-S12 shoots HD (1280x720) at 24 fps using Motion JPEG, a large and less efficient codec, limiting recording times and editing options.
• Panasonic LX5 records 720p up to 60 fps in AVCHD Lite, a more compressed format providing smoother footage and better workflow.

Neither camera offers microphone or headphone jacks, so audio quality is basic. The LX5’s optical image stabilization helps reduce shaky footage, an advantage over the Casio’s lack of any stabilization feature.

Connectivity and Storage

The Casio EX-S12 supports wireless transfer with Eye-Fi card compatibility, a neat albeit outdated tech trick for instant uploads (though Eye-Fi itself is discontinued). Panasonic LX5 lacks wireless connectivity but supports SDXC cards, beneficial for longer shoots. Both cameras have USB 2.0 and HDMI outputs for data transfer and viewing.

The Verdict Summed Up in Scores and Use Cases

It’s crunch time. Here’s a detailed performance overview rated from my hundreds of hours with these cameras.

The Panasonic LX5 clearly dominates in most photographic disciplines, especially where image quality, manual control, and versatility count. The Casio EX-S12’s appeal is its extreme portability, simplicity, and budget-friendly price tag but at the expense of creativity and technical performance.
