Pentax K-01 vs Pentax K100D Super: An In-Depth Comparison for Photographers Today

As someone who has tested hundreds of cameras over 15 years - ranging from entry-level bodies to pro-grade rigs - I’m always fascinated by how different generations of gear compare in real-world use. Today, I’m diving into a detailed comparison of two Pentax cameras that, despite sharing a mount and entry-level target, offer markedly different experiences: the mirrorless Pentax K-01 (2012) and the DSLR Pentax K100D Super (2007). This side-by-side will break down their technical features, performance, and practical usability across various photography styles, helping you see which one fits your needs best.

I’ve personally handled both cameras extensively in studio, outdoor, and travel conditions, and I’ll weave in those experiences alongside detailed specs. Let’s start by looking at their physical designs and handling.

Form Factor and Handling - Old School DSLR or Trendy Mirrorless?

What immediately stands out here is how different these two cameras feel in the hand. The K-01 features an unconventional, “industrial” SLR-style mirrorless body designed by Kazuo Kawasaki. It’s surprisingly chunky and dense for a mirrorless in its class, with a unique, flat-faced front.

In contrast, the K100D Super is a classic compact DSLR shape from the mid-2000s era, more rounded and conservative in styling.

Physically, the K-01 measures a compact 122x79x58 mm, weighing 561g; the K100D S is a bit larger and heavier at 129x91x71 mm and 646g. The extra weight in the K100D S comes mostly from its mirror and pentamirror assembly, as well as a more traditional DSLR build. The K-01’s weight is more distributed due to its mirrorless design and denser body shell.

Ergonomically, I found the K100D S offers a more natural grip, especially for larger hands, with a deeper handgrip and intuitive button layout. The K-01’s grip is smaller and flat, which may disadvantage prolonged use, but some users will appreciate its bold aesthetics and somewhat retro-futuristic vibe.

Top Controls and Design Layout

The control scheme on both cameras reflects their eras and target users.

The K100D Super features a conventional DSLR top plate with dedicated mode dial, shutter speed dial, and exposure compensation buttons - ideal for rapid, tactile changes without diving into menus. The K-01, being mirrorless and somewhat minimalist, drops dedicated mode dials for more button presses and a mode ring on the lens mount itself, which can frustrate some traditionalists but pleases mirrorless enthusiasts who appreciate a streamlined body.

Neither camera offers illuminated buttons, so working in dim environments requires a learned button layout rather than visual cues. My testing shows that if quick, tactile control is your priority, the K100D S wins in this category.

Sensor and Image Quality - CMOS vs CCD, 16MP vs 6MP

This is the most foundational technical contrast. The K-01 is equipped with a 16-megapixel APS-C CMOS sensor (23.7x15.7 mm), delivering up to 4928x3264 resolution, newer sensor tech, and better dynamic range. The K100D S sports a 6-megapixel APS-C CCD sensor (23.5x15.7 mm) with a maximum image size of 3008x2008.

See the size and sensor comparisons below which emphasize this difference.

What This Means in Practice

• The K-01’s CMOS sensor permits higher native ISO (100-12800) with boosted ISO to 25600, offering reliable low-light capabilities and less noise. Its DxOMark scores (overall 79, dynamic range 12.9 EV) indicate solid performance for an entry-level body.
• The K100D S’s CCD sensor maxes out at ISO 3200 native with no ISO expansion and is generally noisier at high ISOs by modern standards. CCD sensors are known for slightly richer color rendition but limited dynamic range and increased noise at higher ISOs.

From my studio and outdoor tests, I observed the K-01 produces sharper, more detailed images with better color depth (DxO reports 23.7-bit color depth vs. not tested for K100D S). The K100D S is adequate at base ISO in good light but struggles in low-light environments, particularly for night or event photography.

Rear LCD and User Interface

Since we spend most shooting time looking through viewfinders or at rear screens, this matters greatly for composition and reviewing shots.

The K-01 has a modern 3-inch, 921k-dot TFT LCD fixed screen, providing crisp, bright previews, histogram overlays, and menu navigation. The K100D S’s smaller, lower-res 2.5-inch, 210k-dot LCD feels noticeably dated, especially outdoors under bright sunlight.

Neither camera offers touchscreen capabilities or articulating displays, which is somewhat limiting for shooting from tricky angles or selfie-style vlogging. The K-01’s live-view (enabled by mirrorless design) makes manual focusing easier, whereas the K100D S lacks live-view entirely, relying on viewfinder reflex focusing.

In my experience, the K-01’s larger, clearer screen noticeably improves framing accuracy and immediate review, crucial for travel and street shooters working on the fly.

Autofocus Systems: Contrast-Detection vs Phase Detection

The Pentax K-01 employs a contrast-detection autofocus system with 81 focus points and features face detection in live view. The K100D Super uses a traditional DSLR phase-detection autofocus system with 11 AF points.

While 81 AF points sound impressive on the K-01, contrast detection generally results in slower focus acquisition and less reliable tracking in continuous or sports scenarios. The K100D’s phase-detection system is faster and more predictable for moving subjects but offers fewer points and lacks modern tracking capabilities.

In wildlife and sports shooting trials, the K100D S was able to lock focus more efficiently on moving subjects under good light, although its modest burst rate (3 fps) limited action capture. The K-01 boasts a 6 fps burst but autofocus slows down continuous tracking.

Both cameras omit animal eye AF or advanced tracking algorithms standard in contemporary mirrorless cameras, which somewhat handicaps wildlife photography enthusiasts.

Burst Shooting and Performance

The K-01 provides a respectable 6 frames per second continuous shooting speed, whereas the K100D S responds at a plodding 3 fps. This is an expected generational difference - mirrorless cameras typically leverage electronic shutter advantages and sensor readout speeds.

For sports or action photographers who require rapid framing, the K-01’s faster burst benefit outweighs the less predictable contrast-detection AF. Still, both are behind modern APS-C cameras easily hitting 10-15 fps with advanced AF tracking.

Weather Sealing and Durability

Neither the K-01 nor the K100D Super offer weather sealing, dustproofing, or shock resistance, meaning both must be treated carefully in inclement or rough shooting environments.

While the K100D’s DSLR shell feels sturdier and can better withstand knocks, its older polycarbonate body doesn’t secure against rain or dust. The K-01’s design is quite rigid, yet the lack of environmental sealing is a limitation for landscape or travel shooters requiring rugged reliability.

Lens Ecosystems - The Advantage of Pentax KAF2 Mount

One big plus: both cameras utilize Pentax’s extensive KAF2 mount, compatible with over 150 lenses spanning decades of design, including legacy primes, modern autofocus standards, and specialized optics.

This means if you already have a Pentax lens collection (or plan to buy third-party/manual focus lenses), both cameras can make excellent use of that ecosystem.

Mirrorless vs DSLR mount differences do not apply here, as the K-01 fully supports the KAF2 mount with appropriate adapters.

Battery Life and Storage

The K-01 uses a rechargeable D-LI90 Lithium-Ion battery rated for around 540 shots per charge, decent for a mirrorless camera.

Conversely, the K100D S runs on 4 AA batteries, which offers the convenience of replaceability anywhere but limits longevity and involves heavier carrying weight.

For lengthy travel shoots, I found the K-01’s ability to recharge via USB (with aftermarket chargers) preferable to carrying multiple AA packs.

Both cameras offer single card slots (SD/SDHC/SDXC for K-01, SD/SDHC for K100D S), supporting everyday storage reliably.

Connectivity and Modern Features

Modern wireless connectivity is absent on both cameras: no Wi-Fi, Bluetooth, NFC, or GPS modules. This significantly limits options for instant image transfer or tethered shooting, putting both models out of step with current expectations.

The K-01 adds useful HDMI output and a microphone port for video recording - a feature the K100D S lacks, which is unsurprising given its 2007 release.

Video Capabilities - Modest Video from the K-01, None from K100D S

Video shooters will find the K-01 surprisingly capable for its era, capturing Full HD 1080p video at 30fps, including slower frame rates for smooth motion. The K100D Super does not support video recording.

Both cameras record in MPEG-4 and H.264 on the K-01 with an external microphone port, allowing reasonable sound capture. The absence of in-body stabilization modes or 4K capabilities limits video quality compared to modern standards.

Real-World Use Across Photography Genres

Let me walk you through how these cameras hold up across popular photography disciplines:

Portrait Photography

The K-01’s higher resolution sensor and improved color depth benefit skin tone reproduction notably. Its face detection AF supports more accurate focus on eyes in live view, yielding creamy backgrounds with quality K-mount primes. The K100D S’s 6MP CCD is softer but color-enriched, producing characterful portraits in good light.

Landscape Photography

Dynamic range differences are stark here - K-01’s better highlight and shadow retention shines in landscape shots under challenging sky conditions. Combined with compatibility for weather-sealed wide-angle Pentax lenses, it’s superior for serious landscape work. K100D S is more limiting due to lower resolution and narrower tonal latitude.

Wildlife and Sports Photography

Higher burst speed and video on the K-01 favor action contexts. But phase-detection AF on K100D S captures moving subjects more reliably under bright conditions. Both lack sophisticated tracking AF, so neither is ideal for fast-paced wildlife or sports compared to newer models.

Street Photography

The K-01’s compact size and quieter operation suit discreet street shooting better than a bulkier DSLR. The larger, clearer screen aids composition on the go. However, the absence of a viewfinder (optical or electronic) detracts from quick, instinctive framing compared to the K100D S’s optical pentamirror viewfinder, which is still excellent for this use case.

Macro Photography

With sensor-based stabilization on both, and access to Pentax’s extensive macro lenses, both can handle close focus well. The K-01’s higher resolution helps capture finer macro details more effectively.

Night and Astro Photography

K-01’s low-light ISO performance and wider sensitivity range are essential for astro photography, plus longer exposure capabilities. The K100D S’s higher base ISO and older sensor limit its usefulness in near-dark conditions.

Video Production

Only K-01 supports video recording, making it a modest yet capable hybrid kit for casual videography. Limitations include lack of headphone jack and advanced video profiles.

Travel Photography

The K-01 strikes a balance of compactness, image quality, and battery life optimal for travel shooters. The K100D S’s bulk and lower ISO flexibility make it a more cumbersome option.

Professional Workflow

File format support (RAW on both) and USB connectivity provide basic tethering and post-processing compatibility. The lack of wireless features, dual card slots, or rugged construction restrict professional use.

Gallery Samples: Real-World Image Comparison

I’ve included a side-by-side gallery of unedited JPEG images captured with each camera under identical settings and lighting.
