Pentax K-5 IIs vs Sony S930

Pentax K-5 IIs vs Sony Cyber-shot DSC-S930: A Detailed Comparison for Photography Enthusiasts

When it comes to choosing a camera, the gulf between a mid-size advanced DSLR and a small sensor compact can hardly be wider - at least on paper. But with decades of testing experience behind me, I know that specs tell just part of the story. Practical usability, image quality nuances, and ergonomic comfort often reveal the true winners. Today, we dive deep into comparing the Pentax K-5 IIs, a 2013 mid-range DSLR powerhouse, against the compact Sony Cyber-shot DSC-S930 from 2009. While wildly different in class and intended use, understanding how they stack up across all photography disciplines will help clarify what each delivers to different users.

Whether you’re a demanding enthusiast hunting rugged versatility or a casual snapshooter on a budget, this comparison blends hands-on insights with technical analysis. Let’s start by sizing them up.

Size and Handling: Ergonomics Matter in Every Shoot

Looking first at form factor, the contrast is stark but expected. The Pentax K-5 IIs is a traditional DSLR body, measuring 131x97x73 mm and weighing 760 grams. Its grip is substantial, designed for comfortable hand-holding over extended sessions, with easy access to dials and buttons. In contrast, the Sony S930 is a lightweight, pocket-friendly compact at 90x61x26 mm and a mere 167 grams, emphasizing portability over control.

Having tested both extensively, I can tell you that the K-5 IIs’s weight and build exude confidence and reliability - it stays rock steady when you’re framing through the pentaprism viewfinder or shooting at telephoto focal lengths. The Sony, while delightfully discreet, sacrifices that ergonomic security. For street photography or simple snapshots, its compact nature is a boon, but when precision and stability matter - like in wildlife or sports - the K-5 IIs absolutely wins in handling comfort.

Ergonomics also extend to control layout, which brings us to the design on top.

Layout and Control: Intuitive Handling vs Simplified Operation

The Pentax features an advanced control scheme - dedicated dials for shutter speed and ISO, a top LCD screen for instant information, and clearly labeled buttons for modes and exposure compensation. This design reflects a professional-grade workflow, aiming to minimize menu diving. Its exposure and focus settings can be quickly toggled, enabling rapid adaptability to changing scenes.

Sony’s S930 opts for a pared-down interface befitting its compact nature, with fewer direct controls and reliance on menus. The shutter speed range caps at 1/2000 s, which limits freezing fast action, and there’s no manual exposure or aperture priority mode - a serious limitation for enthusiasts wanting creative control.

As someone who’s balanced manual dials against menu navigation in real shoots, I prefer the physical controls of the Pentax when speed and precision are key, especially in dynamic environments like sports or wildlife. The Sony’s operation is straightforward but feels restrictive after extended use.

Sensor and Image Quality: The Heartbeat of Any Camera

Here the gap widens considerably. The Pentax K-5 IIs boasts a 16-megapixel APS-C CMOS sensor measuring 23.7 x 15.7 mm, with no anti-aliasing filter - a design choice that boosts sharpness and fine detail resolution dramatically. The Sony S930, on the other hand, uses a much smaller 1/2.3-inch CCD sensor at 6.17 x 4.55 mm, with just 10 megapixels.

This translates directly into practical differences:

• Resolution & Detail: The K-5 IIs can produce images at 4928 x 3264 pixels with fine detail, well suited for large prints and cropping flexibility. The smaller Sony sensor’s 3648 x 2736 max resolution limits large enlargements.

• Dynamic Range: According to DxOmark, the K-5 IIs achieves an exceptional 14.1 EV, allowing it to capture extensive shadow and highlight information - critical for landscape and outdoor photography. The Sony’s small sensor typically delivers compressed dynamic range, causing loss of subtle tonal gradations.

• Low Light Performance & ISO: The Pentax native ISO spans 100-12800 (expandable to 51200), with impressive noise control up to ISO 1600 or 3200 - a boon for night, sports, and indoor shooting. The Sony maxes out at ISO 3200 but is far noisier at higher sensitivities, limiting usable low-light performance.

• Color Depth: The 23.9-bit color depth of the Pentax allows nuanced skin tones and vibrant landscapes, whereas the smaller Sony sensor can appear less precise in color rendition.

From personal experience, the absence of an anti-alias filter in the K-5 IIs translates into crisper images, especially noticeable in texture-rich scenes like foliage or architectural detail. However, it is not without the risk of moiré in patterned subjects, which requires careful handling.

Viewing and Interface: The User’s Window to the World

The K-5 IIs sports a solid 3-inch fixed TFT LCD screen with 921k-dot resolution, providing bright and sharp image review and menu navigation. While it lacks touch functionality, its responsive buttons and dials balance out this omission.

By comparison, the Sony’s 2.4-inch display has only 112k-dot resolution, significantly less detailed. No viewfinder is present, which forces reliance on the LCD. In bright sunlight, this can hamper composition and review.

Importantly, the Pentax offers an optical pentaprism viewfinder with 100% coverage and 0.61x magnification - a vital advantage for manual-focused portrait and landscape shooters seeking precise framing. Without a viewfinder, the Sony lacks this tool, making it less suitable for pro-oriented framing tasks.

Autofocus and Shooting Speed: Tracking the Action

The K-5 IIs integrates an 11-point phase-detection AF system with 9 cross-type points - fairly advanced for its era - plus face detection, center-weighted metering, and live view contrast detection AF for video and live framing. It supports continuous AF tracking at 7 fps burst rate, ideal for wildlife and sports.

Conversely, the Sony S930 employs a 9-point contrast-detection AF without face or eye detection, limiting accuracy, especially in low contrast or fast-moving subjects. The 2 fps continuous shooting speed is sluggish for action photography.

Through hours of field testing, I find the Pentax’s AF gives reliable locks with telephoto lenses, keeping up well with birds in flight or athletes in motion. The Sony best serves still, well-lit subjects at moderate speeds.

Build Quality and Durability: Ready for the Elements?

Pentax is renowned for weather-resistant bodies and the K-5 IIs boasts environmental sealing - magnesium alloy chassis with drought- and cold-resistant design. This makes it a preferable choice for outdoor shooters tackling landscapes or wildlife in rugged conditions.

The Sony compact shows no weather sealing, prioritizing pocketability over ruggedness. Its plasticky build and lack of dust/moisture resistance make it vulnerable to harsh environments.

If you plan serious outdoor use in demanding climates, the Pentax’s durability is a major plus that will save headaches.

Lens Ecosystem: Creative Flexibility or Fixed Convenience?

The Pentax KAF2 lens mount supports over 150 Pentax lenses, ranging from ultra-wide primes to professional telephotos, plus vintage lenses adapted with appropriate adapters. This versatility is a decisive advantage for enthusiasts and professionals wanting tailored optics.

The Sony S930 comes with a fixed 38-108mm equivalent zoom with maximum aperture F2.9-5.4. While decent for everyday snapshots and moderate zoom, it is no match for interchangeable lens systems' flexibility.

In practice, I’ve found that having lens options dramatically affects creative potential - whether for shallow portraits, macro shots, or vast landscapes - whereas fixed zoom compacts can only approximate these styles.

Battery Life and Storage: Keeping You Shooting

The Pentax K-5 IIs uses a rechargeable D-LI90 battery rated for an impressive 980 shots per charge, sufficient for a day’s solid shooting without recharging. It stores images on SD/SDHC/SDXC cards with a single slot.

The Sony relies on two AA batteries - nice for convenience but less eco-friendly and often shorter-lived per charge compared to lithium-ion packs. Storage uses Memory Stick Duo / Pro Duo formats, increasingly obsolete compared to ubiquitous SD cards.

A photographer out in the field will appreciate the Pentax’s longer battery life and standard storage media compatibility.

Connectivity and Video: Modern Demands and Limitations

Neither camera offers wireless connectivity, Bluetooth, or NFC. The K-5 IIs provides HDMI and USB 2.0 output, while the Sony has no USB port or HDMI, limiting data transfer and external display options.

For video, the Pentax records 1080p Full HD at 25 fps with stereo microphone input - a respectable feature when paired with image stabilization. The Sony’s video maxes out at 320 x 240 pixels, quite outdated and unsuitable for any professional video.

Video shooters clearly gain more from the Pentax’s capabilities, although it lacks advanced features like 4K or continuous AF during video.

Real-World Performance Across Photography Genres

To grasp where each camera shines or struggles, let's analyze their performance by photography discipline.

Portrait Photography: Skin Tones and Bokeh

The Pentax’s large sensor, no AA filter, and extensive lens options enable beautiful skin rendition and smooth background separation (bokeh), particularly with fast primes. Its face detection AF adds usability, and optical viewfinder aids precise composition.

The Sony’s small sensor creates sharper compression in backgrounds but renders images with less separation, and limited control over depth of field reduces creative portraiture options. No face detection makes focus hunting occasionally frustrating.

Landscape Photography: Resolution and Dynamic Range

Pentax’s 16 MP sensor with 14 stops dynamic range provides stunning landscape images with breathtaking detail retention in shadows and skies. Weather sealing protects in challenging outdoor conditions.

Sony’s smaller sensor and narrower dynamic range deliver more contrasty but flatter pictures with less post-processing latitude.
