Casio EX-ZR100 vs Pentax MX-1: Small Sensor Compacts Put to the Test

Choosing the right compact camera can feel like joining a secret club of cheapskates - you want the best bang for your buck without hauling around clubs for thumbs (aka a giant DSLR). Today, we’re putting two small sensor compacts head-to-head: the 2011 Casio EX-ZR100 superzoom and the 2013 Pentax MX-1 premium compact. Both are classic examples of their breed but offer vastly different capabilities, handling, and image quality.

Having spent countless hours shooting, tinkering, and pushing cameras to the brink for over 15 years, I’m here to break down what really matters in real-world use - not just pixel peeping or spec sheet one-upmanship. Whether you’re an enthusiast on a budget or a pro looking for a pocket carry-around, this detailed comparison will highlight who should buy which and why.

Let’s dive in.

Size, Ergonomics & Handling: Feel the Difference

When you grab your camera as the decisive photo moment approaches, fit and feel matter as much as sensor tech.

At a glance, the Casio EX-ZR100 is a slim, lightweight superzoom compact, measuring just 105x59x29 mm and weighing a featherlight 204g. Compact doesn’t even begin to capture how portable it is - pockets will love it.

On the flipside, the Pentax MX-1 is chunkier at 122x61x51 mm, nearly double the weight at 391g, and feels solidly built - bordering on mini-DLSR territory. The MX-1’s heft is due to its premium lens and metal construction, which lends confidence but detracts from absolute portability.

Controls tell the story: Casio’s EX-ZR100 opts for a straightforward, button-light approach, great for casual use but offering limited direct manual control. The MX-1, meanwhile, dials into enthusiast territory with dedicated dials for shutter speed, aperture, and exposure compensation. This bodes well for those who want full creative control without diving into menus.

My take: If you prioritize pocket-friendly convenience and long zoom reach, the EX-ZR100 wins. But if tactile controls and a robust grip feel are high on your list, the MX-1 justifies its bulk.

Sensor Size and Image Quality: More Than Pixels

A compact camera’s sensor is its heartbeat. Size and technology here profoundly affect sharpness, noise, dynamic range, and color fidelity.

At the core, the EX-ZR100 sports a modest 1/2.3" BSI-CMOS sensor measuring 6.17x4.55 mm with 12 MP resolution. It is a small sensor by today’s standards, which limits dynamic range and low-light performance due to smaller individual pixels catching less light.

The Pentax MX-1 ups the ante with a larger 1/1.7" CMOS sensor at 7.44x5.58 mm, also 12 MP, offering a significantly larger sensor area of 41.52 mm² compared to Casio’s 28.07 mm². Larger sensor means bigger photosites, translating to improved color depth, better noise control at higher ISO, and wider dynamic range. DXOMark scores back this up - the MX-1 scores a respectable 49 overall, thanks to a color depth of 20.4 bits, dynamic range of 11.3 EV, and low-light ISO performance rated at ISO 208. Casio’s EX-ZR100, unfortunately, remains untested by DXO, but given the sensor size and technology, we expect more noise and less latitude for tough lighting conditions.

Technical insight: Sensor size increases are the most effective way to improve image quality in compacts. Despite sharing 12MP resolutions, the MX-1’s sensor design yields crisper detail and cleaner images in practical shooting.

Screen, Viewfinder & User Interface: Eye Candy and Usability

A sharp, responsive screen is the photographer’s window to the world.

Both cameras have 3-inch rear LCDs, but the MX-1’s 920k-dot TFT screen is brighter, crisper, and sports a tilting mechanism for creative angles. The Casio relies on a fixed 461k-dot “Super Clear” TFT display - fine for framing and reviewing but a bit dim in sunlight and no flexibility for waist-level or overhead shooting.

Neither camera has a viewfinder, not even electronic. This might put off pro shooters, though it’s common for small sensor compacts.

The MX-1 interface benefits from physical dials complemented by menu navigation that’s logical and responsive. Casio’s menus are more basic, prioritizing simplicity over depth. Both lack touchscreen functionality, which feels dated in 2013/2011 releases but was typical then.

Autofocus and Shooting Speed: Fast Enough for What?

Now, how do these two handle subject hunting - fast-moving birds or kids on the go?

Autofocus is contrast-detection and somewhat pedestrian on both, given the compact sensor segment and age. But nuances matter.

The EX-ZR100 offers multi-area contrast AF, single AF mode only (no continuous tracking), and face detection is absent. It does boast a notably rapid burst mode of 40 fps, but only at a reduced resolution and for a short buffer. This makes it fun for capturing a quick series of frames when timing is critical but limits long continuous shooting sessions.

Pentax MX-1 improves the AF game with 25 focus points, face detection, and continuous AF tracking, which make it friendlier for moving subjects in portraits, sports, or wildlife at close range. Burst speed is limited to a disappointing 1 fps, making it unsuitable for extended action shooting but dependable for deliberate exposures.

My advice: For casual shooting where speed is a bonus, Casio’s EX-ZR100 burst offers a quirky perk. For more precise focusing and subject tracking, MX-1 is more trustworthy.

Lens and Zoom Capabilities: Reach vs. Crispness

Lens design dramatically influences actual image impact and use cases.

Casio EX-ZR100: Covers a massive 24-300 mm equivalent focal range with a 12.5x zoom, from moderate wide to super telephoto. Maximum aperture spans f/3.0-5.9. While impressive for travel and wildlife remotely, optical quality dips at extremes with softness and chromatic aberrations creeping in. Macro focusing distances are unspecified but minimal for true close-ups.

Pentax MX-1: Houses a brighter 28-112 mm lens with f/1.8-2.5 aperture, offering superb low-light capability and beautiful background blur (bokeh). The 4x zoom is notably shorter but sharper across ranges with better contrast and color rendition. Macro focusing is impressive, down to 1 cm, allowing crisp close-up shots ideal for nature or product photography.

Real-world impact: If your priority is ultimate zoom flexibility on the cheap, Casio delivers. But for quality optics, especially portraits or low-light scenes, Pentax reigns.

Image Stabilization and Low Light Performance

Neither camera will replace a tripod for serious stability, but sensor-shift stabilization helps handholding in dim environments.

Both use sensor-shift mechanisms, effectively reducing blur by compensating for slight hand shake. The EX-ZR100 combines this with digital tricks but suffers from noise at ISO beyond 800. The MX-1’s larger sensor and bright lens deliver cleaner images up to ISO 3200, allowing more handheld low-light shots.

Video Features: Modest But Usable

Video capabilities remain modest on both.

EX-ZR100 shoots Full HD 1080p at 30 fps, with multiple other resolutions and even slow motion options up to 1000 fps at reduced res. It encodes in H.264 and has HDMI output. No microphone or headphone jacks limit audio flexibility.

MX-1 also shoots 1080p 30 fps but adds 720p at 60 fps, providing smoother slow-motion playback. Files are MPEG-4 or H.264. Again, no audio ports and no 4K video era limitations.

Neither body features in-body stabilization for video, so consider a gimbal or steady hands.

Diverse Photography Genres: Who’s Best Where?

Let’s translate these specs into real-world genre use:

• Portraits: MX-1’s bright, fast lens (f/1.8-2.5), larger sensor, and face AF make it ideal for flattering skin tones and creamy bokeh. Casio’s narrower apertures and weaker AF limit separation from background.

• Landscape: Both cameras perform well given the sensor size - EX-ZR100’s long zoom helps distant details, but MX-1’s superior DR and resolution better capture subtle tonal shifts and textures.

• Wildlife: EX-ZR100’s 300 mm reach gives it an edge for wildlife from a distance, though autofocus lags. MX-1’s limited zoom restricts wildlife framing but offers better overall image quality.

• Sports: Neither is truly optimized. Casio’s burst shooting edges marginally for fast action but with lower resolution. Pentax’s continuous AF tracking benefits that decisive shot but slower FPS is a drawback.

• Street Photography: MX-1’s size and lens speed favor street shooters wanting low light discretion and shallow DOF. Casio is easier to pocket, but slower aperture restricts low-light options.

• Macro: Pentax MX-1 excels with 1-cm macro focus, suitable for intricate close-ups. Casio falls short here with no true macro mode.

• Night / Astro: MX-1’s higher ISO handling and longer shutter range (up to 30s) make it marginally better for night shooting. Casio maxes out at 15s.

• Video: Both are entry-level, suitable for casual social clips only.

• Travel: Casio’s weight and zoom dominate ease of travel carry, but MX-1 offers overall higher image quality for souvenirs and portraits.

• Professional Work: Neither replaces professional gear, but MX-1’s support for RAW files and manual dials aids workflow integration compared to JPEG-only Casio.

Build Quality and Durability

Neither model offers weather sealing or shockproofing, so treat them delicately in adverse conditions.

MX-1’s metal chassis feels more rugged; Casio is mostly plastic but surprisingly solid given its weight.

Battery Life and Storage

Pentax MX-1's D-Li-106 battery delivers about 290 shots per charge - decent for a compact but not super-enduring.

Casio EX-ZR100 specs do not list exact battery life, but typical compact rates suggest roughly 300-350 shots per charge. Both use SD/SDHC/SDXC cards.

Connectivity & Extras

Pentax edges out with Eye-Fi wireless support for card-based image transfer - a nifty feature for on-the-go sharing.

Casio lacks Wi-Fi, Bluetooth, or NFC entirely.

Both have USB 2.0 and HDMI ports for wired connectivity but neither supports mic or headphones.

Performance Ratings & Value Assessment

Looking at overall ratings (bearing in mind Casio lacks official DXOmark scoring), the MX-1 consistently outperforms the EX-ZR100 across important metrics: image quality, color fidelity, dynamic range, and low-light shooting.

Price-wise, Casio’s typically lands around $300, and the MX-1 closer to $400. For the extra $100, Pentax delivers clear gains in image quality and creative flexibility.
