Fujifilm X-T30 II vs Pentax K-01: The Ultimate Entry-Level Mirrorless Camera Showdown

Choosing the right entry-level mirrorless camera can profoundly shape your photography journey. With so many options on the market, it's crucial to investigate practical, hands-on performance to find a camera that matches your creative ambitions. Today, I’m diving deep into two compelling cameras from different eras and brands: the Fujifilm X-T30 II, announced in 2021, and the Pentax K-01, launched back in 2012. Both are classified as entry-level mirrorless cameras with APS-C sensors and SLR-style bodies, but beyond the specs lies a story of differing philosophies, capabilities, and user experiences.

Having personally tested thousands of cameras over the last 15 years, I will share unique insights rooted in rigorous lab and field evaluations - to help you decide which is truly the better buy for your needs, no matter your photography specialty.

Physical size and ergonomics comparison

First Impressions: Size, Ergonomics, and Handling

Before you get to megapixels and autofocus, the feel of a camera in your hands is paramount. The Fujifilm X-T30 II weighs just 383 grams with dimensions of 118 x 83 x 47 mm, making it a compact and lightweight option tailored for travel and long shooting sessions. In contrast, the Pentax K-01 tips the scales at a heftier 561 grams, measuring 122 x 79 x 58 mm. This difference is noticeable in hand; the K-01 feels more substantial but also bulkier.

The X-T30 II follows Fujifilm's celebrated ergonomics formula, featuring tactile dials on the top plate, intuitive button layout, and an articulated 3-inch tilting touchscreen. The design encourages manual control while maintaining quick access to settings - a must for enthusiasts who want agility on fast-moving subjects. The K-01, however, has a more unconventional, boxy design crafted by the renowned industrial designer Marc Newson. It employs a fixed 3-inch LCD without touch capability, and eschews an electronic viewfinder entirely, instead relying purely on the rear screen for composition.

I found the X-T30 II’s design more natural for handheld shooting and longer use - the grip is deeper, and the controls have a satisfying mechanical feel. Conversely, the K-01’s stark shape, while visually distinctive, feels less ergonomic during extended shoots, particularly for smaller hands.

Controls and User Interface: Navigating Your Creative Workflow

When it comes to user interface and controls, the X-T30 II clearly targets photographers who favor direct manual input. The camera boasts dedicated dials for ISO, shutter speed, and exposure compensation, plus a top LCD for glanceable info without digging into menus. Touchscreen focus point selection and intuitive menu navigation complement this well-thought-out control scheme.

The Pentax K-01, being older and less feature-rich, offers only basic control dials and no touchscreen interface. It also lacks an electronic viewfinder (EVF), so composing solely on the fixed LCD screen can be a challenge in bright conditions, limiting versatility and immediacy. The absence of eye-level framing may be a deal breaker for serious users.

Overall, Fujifilm’s approach demonstrates how design evolves to improve photographer efficiency and joy - something I noticed immediately during testing.

Sensor Technology and Image Quality: A 9-Year Gap Explored

At the heart of any camera is the image sensor, and here the two models clearly differ, reflecting technological progress over nearly a decade.

Sensor specifications and image quality discussion

• Fujifilm X-T30 II: 26.1-megapixel BSI-CMOS sensor, APS-C size (23.5 x 15.6 mm), no anti-aliasing filter for sharper details, ISO range 160–12800 (expandable to 80–51200). The back-illuminated design ensures improved light gathering and low-noise performance.
• Pentax K-01: 16.3-megapixel CMOS sensor, APS-C size (23.7 x 15.7 mm), with anti-aliasing filter. Native ISO 100–12800 (expandable to 25600).

Image Quality Assessment

From my testing, the X-T30 II produces noticeably sharper images with better dynamic range and superior high ISO noise control compared to the K-01. Fujifilm’s sensor architecture benefits from advancements in back-side illumination, resulting in cleaner shadows and smoother gradients - essential for landscape and portrait work.

While the K-01 still holds its own for basic daylight shooting, its older sensor shows signs of noise creeping in at ISO 1600 and above, and highlights clip more quickly. The anti-aliasing filter reduces moiré artifacts but sacrifices some detail resolution.

For photographers who emphasize image sharpness and quality for prints, pixel-level crops, or heavy post-production, the X-T30 II offers a significant edge.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus can make or break your shooting experience, especially for wildlife, sports, or street photography.

• Fujifilm X-T30 II features a hybrid autofocus system with 425 phase-detection points covering a wide area of the frame, complemented by contrast-detection. The camera supports advanced face detection and eye AF for humans (though no animal eye AF).
• Pentax K-01 uses an older contrast-detection system with 81 focus points, no phase detection, and no advanced face or eye tracking features. Continuous AF is available but lacks subject tracking.

In practice, I found the Fujifilm far superior for action and moving subjects. The X-T30 II’s autofocus locks on quickly and maintains focus through erratic motion, even in dimmer conditions down to -3 EV. Its eye detection works well for portraits, consistently capturing sharp, well-focused eyes, leading to dramatically improved keeper rates.

The K-01’s slower contrast AF means lag and hunting under challenging conditions, making it frustrating for fast-moving subjects or spontaneous moments. For portraiture, the lack of eye detection means you must manually ensure focus on eyes - possible, but less convenient.

If autofocus reliability matters for your primary uses, particularly wildlife, sports, or event photography, the X-T30 II offers clear practical benefits.

Burst Shooting and Buffer Depth: Never Miss the Moment

Continuous shooting speeds greatly affect ability to capture fleeting action:

• Fujifilm X-T30 II offers blistering 30 frames per second with electronic shutter (up to 1/32000s), reasonable for sports and wildlife bursts.
• Pentax K-01 caps out at just 6 fps with no electronic shutter option.

In my field tests at a fast-paced sports event, I noted the Fujifilm catches key moments fluidly without buffer bottlenecks. The Pentax’s slower rate risks missing critical expressions or action frames, limiting its utility for action-heavy photography.

Video Capabilities: A Decade of Advancement

Video has become essential alongside stills, and here the gap between these cameras is stark.

• The X-T30 II records up to 4K UHD at 30 fps, with a bit rate of 200 Mbps, plus Full HD up to 120 fps for slow-motion. It supports microphone and headphone jacks for monitoring and audio control, and uses advanced codecs like H.264.
• The K-01 maxes out at Full HD (1920x1080) 30 fps, with no 4K option, only a microphone port but no headphone jack, limiting audio monitoring.

I tested both with professional microphones; the X-T30 II yielded noticeably better video detail, color fidelity, and smoother frame rates. Its in-body autofocus during video is functional, though not flawless, while the K-01’s focus during video relies on slower contrast detection and can hunt noticeably.

For aspiring hybrid shooters, content creators, or videographers, the Fujifilm stands far ahead in features and quality.

LCD screen and interface comparison

Display and Viewfinder: Composition and Playback Tools

The rear display and viewfinder directly affect composition and image review:

• X-T30 II has a bright, high-resolution 3-inch tilting touchscreen at 1.04 million dots, which supports touch focus and menu control.
• K-01 uses a fixed 3-inch 921k dot TFT LCD, no touch, and notably no viewfinder (optical or electronic).

Shooting outdoors, I found the X-T30 II’s screen easier to angle for waist-level shots or overhead views, with superior brightness under sunlight. Touch capabilities speed up AF point selection and menu navigation. The lack of any viewfinder on the K-01 makes handheld composition awkward in bright light, forcing squinting or ducking behind shade.

For photographers who value quick, versatile framing, the Fujifilm’s screen and integrated electronic viewfinder (with 2.36-million-dot resolution) are tremendous advantages.

Build Quality and Weather Sealing: Durability in the Field

Neither camera is weather sealed or boasts professional-grade ruggedness, but there are differences:

• The K-01’s all-metal body feels sturdy but adds weight and bulk.
• The X-T30 II uses a high-quality polycarbonate shell over a magnesium alloy chassis - lighter but less rugged.

Given the lack of environmental sealing on both, neither is ideal for harsh weather without protective covers. However, the X-T30 II’s lighter build and superior ergonomics make it preferable for travel and handheld shooting in varied conditions.

Lens Ecosystem: The Power of Choice Behind the Camera

Lens availability often shapes a user’s long-term satisfaction:

• Fujifilm’s X-mount boasts over 62 native lenses ranging from super fast primes to versatile zooms, with an emphasis on optical quality and compactness. Fujifilm also benefits from strong third-party support from Zeiss, Sigma, and others.
• The Pentax K-01 uses the KAF2 mount, which supports a vast legacy of 151 lenses (though many are DSLR-oriented, larger, and heavier). Limited native mirrorless-specific designs mean compromises in size and autofocus speed.

In practical use, I appreciated Fujifilm’s streamlined system for mirrorless shooting, especially with compact primes for street and travel work. Pentax’s lens options are extensive if you’re invested in their ecosystem or DSLR legacy, but lenses tend to be bulkier, reflecting their DSLR heritage.
