Casio EX-ZR700 vs. Leica V-Lux 20: An Expert’s Take on Two Small Sensor Superzoom Compacts

Choosing the right superzoom compact camera is a nuanced decision - for enthusiasts and even professionals looking for a lightweight, versatile companion. Today, I put two intriguing contenders head-to-head: the Casio EX-ZR700 (announced 2013) and the Leica V-Lux 20 (2010 model). Both tout small sensors smack dab in the 1/2.3” category, fixed superzoom lenses, and a compact form factor, yet they diverge significantly in design philosophy, image output, and user experience.

Having spent dozens of hands-on hours testing and comparing these models across multiple photography disciplines, I’ll break down their capabilities from sensor technology to real-world versatility. The goal? To give you an authoritative, objective assessment so you can find the camera that fits your style, budget, and performance needs.

Putting Size and Handling Under the Microscope

When choosing a camera, size and ergonomics often set the tone for your shooting experience over months or years. Both cameras are designed for portability yet impact how confidently you hold and operate them is world apart.

Starting with the Casio EX-ZR700: its dimensions (108 × 60 × 31 mm) and weight (222 g) place it firmly in pocketable territory. Its super clear TFT LCD is a bright 3” fixed screen with 922k-dot resolution - a real boon when framing shots in tricky light. I was impressed by the EX-ZR700's somewhat angular grip, which provides decent hold despite the compact body, though the absence of a viewfinder nudges you to rely solely on the backside screen.

The Leica V-Lux 20, similarly compact (103 × 60 × 33 mm) and marginally lighter (218 g), offers a slightly smaller 3” screen but with only 461k-dot resolution. You can feel Leica’s premium intentions in the metal finish and robust build quality, though its fixed lens means ergonomic comfort depends on personal hand size. Neither camera has an electronic or optical viewfinder, which limits precise composition under bright sunlight.

Comparing their top control layouts underscores Leica’s lean into simplicity - few buttons, no illuminated keys - whereas Casio’s EX-ZR700 sports more direct-access controls, reflecting its ambition to serve serious amateurs who appreciate quick adjustments.

In sum, if you prize a more modern screen, slightly chunkier grip, and dedicated controls, Casio’s ergonomics edge ahead. Leica delivers a sleek, elegant silhouette but feels more minimalist - and less flexible - when shooting on the go.

Dissecting the Sensor and Image Quality Potential

Both cameras rely on a 1/2.3” CMOS (Casio) or CCD (Leica) sensor - standard fare for this class, but with distinct technological implications.

Casio’s 16-megapixel CMOS sensor, paired with the EXILIM Engine HS 3 processor, aims for fast response times and high-resolution results (4608×3456 pixels). In my testing, this sensor produced images with decent detail at base ISO 80 through mid-range ISO 400, but noise rapidly crept in as you pushed toward its max ISO 3200. The CMOS design enables efficient sensor-shift stabilization - critical given the long 18× zoom range (25-450 mm equivalent).

In contrast, Leica’s 12MP CCD sensor (4000×3000 pixels) trades resolution for cleaner mid-ISO performance, notably extending up to ISO 6400. CCD technology’s color rendition is often lauded for its creamy tonality and smooth gradation, and I can confirm this as especially pleasant in casual shooting scenarios. However, the optical image stabilization (OIS) system is somewhat less responsive than Casio's sensor-shift.

A key takeaway: Casio offers finer detail when light is ample, but Leica’s sensor shines better in low-light conditions and favors color fidelity over raw resolution. Neither camera supports RAW out of the box, limiting post-processing flexibility - a major consideration if you’re a workflow-focused pro.

Seeing Through Their LCD Screens: A Matter of Visual Feedback

If you’re confined to LCDs and no viewfinder, screen quality becomes paramount in day-to-day usage.

The Casio EX-ZR700’s 3” “Super Clear” TFT LCD with 922,000 dots is noticeably sharper and brighter than the Leica V-Lux 20’s 3” 461k-dot display. This higher resolution aids in judging focus, exposure, and composition - a real advantage if you regularly shoot in bright outdoor environments. The Casio screen doesn’t support touch functionality, which may frustrate some, but it delivers clean menus and generous interface feedback.

Leica’s screen, while adequate, feels somewhat subdued by comparison. Color contrast isn’t as punchy, and its lower pixel density makes zooming in on images for critical review less effective. Still, that’s partly consistent with its more minimalist user experience ethos.

In practice, I found the Casio’s LCD contributed notably to faster, more confident operation in the field - something that can't be overstated when seconds count.

Autofocus Systems Put to the Test: Speed, Precision, and Tracking

AF systems make or break a camera's usability, especially with superzoom lenses where subject movement can blur a shot.

Casio’s EX-ZR700 employs a contrast-detection AF system combined with face detection and a type of AF tracking (not continuous), supplemented by center-weighted focus area. You have manual focus options with the lens, which is a welcome inclusion for macro or precision work.

Leica's V-Lux 20 also uses contrast-detection AF, with 11 focus points (a more structured matrix), but crucially, it lacks face detection and AF tracking modes. Manual focus is electronic, due to absence of mechanical focus ring control. During wildlife or sports tests, the Leica’s focus acquisition felt slower and less reliable on fast-moving targets.

Continuous AF isn’t supported on either camera, limiting action photography reliability.

For static subjects or portraits, both cameras achieve acceptable focus accuracy. Casio’s face detection greatly simplifies portrait sessions and street shots, though lack of eye-detection AF leaves some hunting. Leica’s more limited AF suite means you frequently hunt manually or rely on center spot, less ideal under time pressure.

Zoom Lenses & Optical Performance: Flexibility vs. Reach

The optical zoom is a critical spec for travel, wildlife, and general versatility. Here the cameras diverge in focal length and aperture ranges.

• Casio EX-ZR700: 25-450 mm equivalent (18× zoom), f/3.5-5.9 max aperture
• Leica V-Lux 20: 25-300 mm equivalent (12× zoom), f/3.3-4.9 max aperture

Clearly, Casio pushes reach-way out with an 18× zoom that’s impressive on paper and in field use. That extra telephoto range is solid for wildlife and distant subjects. However, this comes with a tradeoff: smaller max aperture at the long end and more noticeable softness at full zoom - typical superzoom refractive compromises.

Leica, with its shorter 12× zoom, maintains slightly brighter aperture values throughout, improving low-light handholding and background blur potential. Also, its minimum macro focus distance (3 cm) is tighter than Casio’s 5 cm, beneficial for closer detail shots.

Both lenses are fixed and cannot be swapped, meaning you’ll live within these parameters. Optical stabilization (Leica) and sensor-shift (Casio) help mitigate shake, but at extreme zoom lengths, tripod support is recommended.

Overall, Casio appeals if reach and versatile focal coverage are priorities; Leica offers a slightly faster lens range well suited for urban and travel shooting.

Picture This: Real-World Image Samples

Numbers and specs only tell so much - you want to see sample images comparing detail, color, and dynamic range in practical conditions.

In daylight landscapes, Casio’s 16MP sensor captures crisp textures with finer detail rendition. Contrast is balanced but can feel slightly punchy after in-camera JPEG processing. Colors skew toward cooler tones, which might require tweaking for skin tones in portraits.

Leica’s images shimmer with warm, natural color rendition, and smoother tonal transitions - especially evident in skin and foliage. The lower resolution softens edge acuity, particularly when cropping.

In low light, Leica’s extended ISO capacity allows cleaner, usable images at ISO 800 and beyond, while Casio’s photos show more luminance noise past ISO 400. Street photography benefits from this latitude.

Both cameras struggle to hold highlight details in harsh contrast, but Leica’s multi-segment metering sometimes handles high dynamic range scenes more gracefully, preserving shadows.

Burst, Shutter Speeds, and Video Capabilities

When shooting sports, wildlife, or videos, speed and frame rates matter a lot.

Casio offers a maximum continuous shot speed of 3 fps with shutter speeds from 4 to 1/2000 sec. Its video mode supports Full HD 1080p at 30 fps, including 720p at up to 120 fps for slow motion - noteworthy for a compact from this era. However, it lacks external mic input or headphone jack, and video codec options are limited to MPEG-4/H.264.

Leica provides only 2 fps burst shooting and a shutter speed range maxing out at 1/2000 sec. Video maxes out at 720p 60 fps, encoded as Motion JPEG - a heavier codec with lower compression and larger file sizes. No audio input options exist either, and slow-motion video isn’t supported.

For dedicated videographers, Casio stands out modestly but neither camera aims to replace modern mirrorless models in video prowess.

Toughness, Connectivity, and Power: The Everyday Essentials

Neither camera boasts weather sealing, waterproofing, or ruggedness, so exercise caution in challenging environments.

The Casio EX-ZR700’s battery yields an estimated 470 shots per charge - a strong performance for compact cameras of this class - using the NP-130 battery pack. Leica doesn’t specify battery life, but anecdotal evidence suggests shorter endurance, partly due to the power-hungry CCD sensor.

Storage compatibility: Both use SD/SDHC/SDXC cards, but Leica supports internal storage as well. USB 2.0 and HDMI ports exist on both - not blazing fast, but adequate for image transfer and external displays.

Neither supports Wi-Fi, Bluetooth, or NFC connectivity - understandable given their early 2010–2013 eras. Leica sports built-in GPS, an uncommon feature in small compacts that gives an edge to travel photographers mapping their shots.
