When shopping for a Pentax camera, you’re often choosing between rugged reliability and affordability or advanced features and versatility. In this detailed comparison, I pit the Pentax K-01 - a bold, retro-styled entry-level mirrorless camera from 2012 - against the more recent Pentax KP, a 2017 mid-size DSLR packed with pro-grade capabilities. Having personally tested both models extensively over varied shooting scenarios spanning portraiture to wildlife, I’ll walk you through their real-world performance, image quality, handling, and value, helping you decide which Pentax fits your photography ambitions in 2024.

How These Cameras Stack Up at a Glance

Before diving into details, here’s a quick look at their fundamental differences:

This image shows the distinctive body designs and sizes of the K-01 versus the KP, setting the tone for their differing target audiences.

Design, Build, and Handling: What It Feels Like in Your Hands

Pentax K-01

The K-01’s unconventional, boxy design - thanks to famed designer Marc Newson - instantly sets it apart. Its compact mirrorless architecture means a smaller, lighter body, which is appealing for portability. The K-01 offers excellent button layout for an entry-level mirrorless and has a fixed 3-inch TFT LCD screen with good resolution (921k dots). However, the lack of a viewfinder - optical or electronic - is a clear drawback, especially in bright conditions.

Ergonomically, the camera’s grip is somewhat shallow but workable for casual shooting and travel. I found it suitable for street photographers favoring discreteness but less comfortable for prolonged handholding with big lenses.

Pentax KP

Conversely, the KP’s robust DSLR-style build really shines in ergonomics. It has a substantial grip and a traditionally intuitive control scheme, highlighted by a tilting 3-inch LCD (also 921k dots) ideal for shooting at awkward angles. Importantly, the KP includes a high-quality optical pentaprism viewfinder, which I personally prefer for fast, clear framing and zero lag.

The KP is weather-sealed against dust and moisture - a feature the K-01 lacks - giving it a rugged edge for outdoor and professional environments. Weighing about 140g more, it's noticeably heftier but feels well balanced with long lenses attached.

This top-down shot highlights how the KP’s dedicated dials and buttons provide faster access to key settings, a boon in dynamic shooting, compared to the minimalist style of the K-01.

Summary

• K-01: Lightweight, bold design, compact but limited ergonomics without a viewfinder.
• KP: Larger, solid, weather-sealed, with classic DSLR handling and full pentaprism OVF.

If you value rugged build and tactile controls for serious use, the KP wins. For casual travel or street shooting prioritizing portability, the K-01’s size is attractive.

Sensor Technology and Image Quality: The Heart of the Matter

Despite both cameras using APS-C CMOS sensors with the same 1.5x crop factor, there are significant differences:

A modest difference in sensor size (K-01 slightly larger) but the KP’s 24MP sensor delivers higher resolution, translating to more detail and greater cropping flexibility - critical for landscape, wildlife, and portrait work.

In controlled lab testing, the KP’s sensor achieves better dynamic range and noise control at high ISO, giving cleaner images in low light. The K-01’s DXOMark scores (overall 79, color depth 23.7 bits, dynamic range 12.9 EV) are respectable for its era but lag behind contemporary APS-C standards.

This graphic illustrates the closeness of sensor areas but highlights how the KP’s more modern sensor design yields superior image quality.

Real-World Impact

• Portraits: The KP offers superior skin tone rendition and more detailed headshots thanks to its higher megapixel count.
• Landscape: Higher resolution and better dynamic range afford the KP more latitude in post-processing shadow recovery.
• Low Light: KP’s extended ISO range excels for night and astro photography, reducing noise significantly vs. K-01.

Autofocus Performance: Speed, Accuracy, and Reliability

Autofocus systems are crucial for many genres, from wildlife to sports:

The K-01’s contrast-detection AF with 81 focus points is quite decent but lacks sophisticated tracking. During my hands-on tracking of moving subjects like kids or sports, the K-01 occasionally lagged or hunted noticeably.

The KP stepping up to a hybrid 27-point system with 25 cross-type sensors and AF tracking offers a much-improved autofocus experience for erratic subjects. In wildlife and sports shooting tests, the KP displayed more reliable continuous autofocus and better subject acquisition. For portrait or street work, both cameras perform adequately, but the KP’s face detection is more dependable.

Continuous Shooting and Buffer Capacity

Faster shooting is essential for capturing decisive moments, especially in action photography:

• K-01: 6 frames per second (fps)
• KP: 7 fps

Though a slight improvement, the KP’s deeper buffer and faster processing allow for longer burst sequences without slowdown, an advantage during sports or wildlife sessions where you might need a sustained rapid-fire shoot.

Viewfinders and LCD Screens: Framing Your Shot

The K-01 lacks any viewfinder, relying solely on a 3-inch fixed TFT LCD screen (921k dots). While the screen performs well in most lighting, shooting under direct sunlight or action scenarios can be challenging.

The KP offers a traditional optical pentaprism viewfinder with 100% field coverage and 0.63x magnification, offering bright, clear, lag-free viewing - invaluable for capturing quick moments or composing carefully.

Both cameras feature a 3-inch, 921k-dot LCD, but the KP offers a tilting design making it more versatile for shooting from low or high angles.

Here you can see the fixed screen on the K-01 versus the articulated tilting screen of the KP.

Build Quality, Weather Sealing, and Durability

The Pentax KP embraces the brand’s reputation for ruggedness with weather sealing for dust and moisture resistance - a huge benefit for outdoor photographers. The K-01, designed as an entry-level mirrorless, lacks any sealing or ruggedization.

If you regularly shoot in challenging environments - outdoors in rain, dust, or cold - the KP is the better companion.

Lens Ecosystem and Compatibility

Both cameras use the Pentax KAF2 mount offering compatibility with a wide range of 151 lenses, including legacy lenses with manual focus.

• K-01: No in-body phase detection autofocus, so autofocus depends on lens motor.
• KP: Supports full autofocus on modern autofocus lenses and retains excellent manual focus controls.

Due to the K-01’s mirrorless body, certain lenses designed for DSLRs may be less optimal ergonomically or with respect to focusing speed.

Video Performance and Usability

Both cameras record Full HD 1080p video but differ in frame rates and codecs.

• K-01: 1080p at 30/25/24 fps; also 720p up to 60 fps; formats include MPEG-4 and H.264.
• KP: 1080p at 60i and 30p; same codecs.

I found the KP’s video module a bit more refined, with better image stabilization (5-axis sensor-shift vs. unspecified sensor-based on K-01). Both models include microphone inputs but lack headphone jacks - limiting on-set audio monitoring.

For casual video shooters or vloggers, both cameras suffice, but those prioritizing video should consider newer models.

Battery Life and Storage Considerations

• K-01: Rated for approximately 540 shots per charge (CIPA standard).
• KP: Rated for around 390 shots per charge.

The K-01 excels in battery efficiency, likely due to fewer power-hungry features like the absence of an optical viewfinder and simpler processor.

Storage for both cameras revolves around SD/SDHC/SDXC cards, but the KP supports faster UHS-I cards beneficial for burst shooting and video.

Connectivity and Wireless Features

The K-01 offers no built-in wireless features - no Wi-Fi, Bluetooth, NFC, or GPS.

The KP, while also lacking Bluetooth or NFC, does have built-in wireless connectivity for remote control - a useful feature absent on the K-01. GPS is optional on the KP via an accessory, suiting outdoor shooters wanting location tagging.
