Pentax K-5 IIs vs. Sony Cyber-shot DSC-H50: An In-depth Comparison from an Expert Photographer’s Perspective

Choosing the right camera can be a daunting task, especially when faced with options as diverse as the Pentax K-5 IIs DSLR and the Sony Cyber-shot DSC-H50 compact superzoom. These two cameras contrast markedly in design, technology, and target users, making a side-by-side comparison valuable for enthusiasts and professionals alike.

Having tested thousands of cameras over 15 years, I’m here to give you a comprehensive, no-fluff look at how these cameras perform in real-world scenarios across multiple photography disciplines. Together, we’ll explore image quality, autofocus, ergonomics, video capabilities, and more - so you can be confidently sure which suits your needs best.

Putting Size and Build Quality into Perspective

Let’s start by physically comparing these two cameras because size, weight, and ergonomics strongly influence usability and photographic style.

Pentax K-5 IIs is a mid-sized DSLR with a robust weather-sealed body, measuring 131 x 97 x 73 mm and weighing 760 g with battery. Its magnesium alloy chassis inspires confidence for outdoor work, particularly where weather is unpredictable. The camera features a comfortable grip and well-placed, tactile buttons that invite hours of shooting without fatigue.

Sony DSC-H50, by contrast, is a compact superzoom bridge camera with dimensions 116 x 81 x 86 mm and a lighter weight of 547 g. While not weather-sealed, its pocket-friendly form factor and built-in 15x zoom lens make it ideal for casual travel and situations where portability is paramount.

In hands-on testing, I found the K-5 IIs designed for deliberate, composed shooting styles due to its size and heft, whereas the H50 felt nimble and spontaneous but less suited to rugged outdoor conditions.

Controls and User Interface: DSLR vs. Bridge Camera Experience

Moving to design details and controls, the Pentax K-5 IIs uses an optical pentaprism viewfinder with 100% coverage - delivering a bright and accurate scene preview favored by many professionals. Controls include dedicated dials for shutter speed, exposure compensation, and shooting modes, allowing quick manual adjustments without menu diving.

The Sony H50 relies on a smaller electronic viewfinder (resolution unspecified) plus a fixed 3-inch LCD with modest 230k-dot resolution. Menus can feel more involved, and the fewer dedicated buttons mean slower access to advanced settings like ISO or white balance. For manual exposures, the H50 includes shutter and aperture priority but lacks some DSLR comforts like illuminated buttons.

The screen difference is notable:

The Pentax’s higher resolution LCD (921k dots) greatly aids in reviewing photos and manual focusing via live view.

From personal experience, photographers seeking fast, tactile command over settings will prefer the K-5 IIs layout. The H50, while functional, caters more to casual shooters or those prioritizing zoom range over refined handling.

Sensor Technology and Image Quality: A Decisive Advantage for the Pentax K-5 IIs

At the heart of photographic output lies sensor size and technology. The Pentax K-5 IIs sports a 16MP APS-C CMOS sensor (23.7 x 15.7 mm), sans optical low-pass filter. This is significant because removing the anti-aliasing filter can boost sharpness and detail resolution - a double-edged sword, as it can increase moiré risk but Pentax achieved a great balance.

By comparison, the Sony H50 uses a small 1/2.3" CCD sensor (6.17 x 4.55 mm) with 9MP resolution. This sensor size is typical for bridge cameras, and presents inherent limitations in dynamic range, noise performance, and detail - especially under challenging lighting.

Real-world testing confirms:

• The K-5 IIs delivers rich, detailed images with excellent color accuracy and tonal gradation, thanks to a dynamic range measured around 14.1 EV (DxOMark). Its color depth (23.9 bits) outperforms the Sony, which was not tested but, based on sensor size, cannot match the DSLR’s image fidelity.
• In low light, the Pentax supports native ISO up to 12800 (boosted 51200) with usable noise control, compared to the Sony’s max 3200 ISO with noisy output.
• The absence of an anti-alias filter in the K-5 IIs markedly improves micro-detail resolution, benefiting portrait skin texture and landscape fine detail alike.

This sensor difference is fundamental and affects almost every photography domain.

Autofocus Systems: Speed and Precision Matter

When photographing moving subjects, autofocus speed and tracking accuracy become vital.

• Pentax K-5 IIs uses an 11-point phase-detection AF system with 9 cross-type sensors, face detection, and robust continuous AF. It does not include animal eye autofocus but delivers reliable eye detection in live view.
• The Sony H50 has a simpler contrast-detection AF with 9 points but no phase detection or continuous AF tracking.

In my wildlife and sports shooting tests, the K-5 IIs locked focus rapidly and maintained tracking on unpredictable subjects with ease at up to 7 frames per second burst rate. The Sony’s slower autofocus and limited burst speed (2 fps) hampered fast-action capture.

For street and macro photography, the H50’s contrast AF performed adequately when subjects were stationary, but evolving focus challenges demonstrate how the DSLR’s system is a major edge for professionals.

Discipline-Specific Performance and Recommendations

Portrait Photography

The Pentax’s large APS-C sensor and aperture flexibility from interchangeable lenses create creamy bokeh and natural skin tones. The lack of anti-aliasing filter enhances detail rendering in eyes and hair. Eye detection autofocus aids precision, a feature absent on the Sony.

In contrast, the Sony H50’s small sensor generates less background separation and a shallower depth-of-field effect. Its fixed lens F2.7-4.5 limits low-light portrait work.

Landscape Photography

Here, the K-5 IIs shines with excellent dynamic range, 16MP resolution, and weather sealing allowing shooting in harsh environments. Its use of SD cards provides ample storage for high-res RAW files, perfect for extended trips.

The Sony’s small sensor and lack of weather sealing restrict image quality and use under demanding conditions, but its superzoom capability may appeal for casual travel landscapes.

Wildlife and Sports Photography

High-speed continuous shooting (7 fps), advanced AF tracking, and telephoto lens compatibility make the Pentax DSLR the clear winner for capturing fast subjects.

The H50’s limited burst rate and less sophisticated AF make it a poor choice for action or wildlife photography, but its long zoom is a bonus for casual birding or distant subjects where budget is tight.

Street Photography

While the Sony’s compact size and zoom range permit discreet shooting, the K-5 IIs’ larger body might attract unwanted attention. However, higher ISO performance and manual controls favor the Pentax for creative street scenes.

Macro Photography

Pentax’s ecosystem offers excellent macro lenses and the DSLR’s sensor-shift image stabilization (in-body) aids sharp handheld close-ups. The Sony’s fixed lens permits macro shooting as close as 1 cm but lacks advanced stabilization, limiting image stability.

Night and Astrophotography

Thanks to higher ISO capabilities and superior noise control, the Pentax excels in low light, making it suitable for nightscape and astrophotography.

The Sony’s smaller sensor struggles with noise and dynamic range, restricting its practical use after dusk.

Video Capabilities

The K-5 IIs supports Full HD 1080p at 25 fps in Motion JPEG format with external microphone input, beneficial for amateur videographers seeking audio quality control.

Sony’s H50 records only VGA 640 x 480 video at 30fps, limiting its utility for modern video needs.

The K-5 IIs’s robust grip and extensive button layout facilitate comfortable day-long shooting sessions, even with heavier lenses. The segmented top LCD provides instant access to key settings, speeding operation in unpredictable light.

By contrast, the H50’s pocketability diminishes operational comfort, especially in colder conditions or prolonged use. The limited resolution of its electronic viewfinder and LCD screen reduce framing precision.

Battery Life and Storage

• Battery: The K-5 IIs uses the D-LI90 lithium-ion pack, rated for approximately 980 shots per charge, tested consistently during my extended shoot sessions. The H50 uses NP-BG1 battery with unspecified real-world endurance, typically lower given its compactity.
• Storage: The Pentax supports SD/SDHC/SDXC cards; the Sony uses proprietary Memory Stick Duo/Pro Duo cards, which are gradually phased out and less widely available or affordable.

Lens Ecosystem and System Expandability

An often-overlooked part of camera value is lens availability.

Pentax K-5 IIs benefits from over 150 compatible KAF2 mount lenses, covering everything from ultra-wide to super-telephoto primes and zooms, plus specialty lenses such as tilt-shift and macro.

The Sony H50 has a fixed lens - 31-465 mm equivalent zoom without the ability to swap lenses, limiting artistic control and reducing future expandability.

Connectivity and Modern Features

The Pentax K-5 IIs lacks Wi-Fi, Bluetooth, and NFC connectivity, relying on USB 2.0 and optional GPS modules. Given its 2013 debut, this is understandable but also a limitation for instant sharing.

Sony H50 offers no wireless connectivity or HDMI output, representing a compromise on modern integration, consistent with its entry-level bridge camera design.

Price-to-Performance Ratio: What Are You Paying For?

At launch and current second-hand prices:
