Pentax K-x vs Sony Cyber-shot DSC-H300: A Hands-On Comparison for the Discerning Photographer

In the ever-evolving world of digital imaging, the choice between a compact DSLR and a superzoom bridge camera remains a pivotal crossroads for many photography enthusiasts. Today, I’ll put two distinct cameras head-to-head: the Pentax K-x, a 2009 entry-level APS-C DSLR, and the Sony Cyber-shot DSC-H300, a 2014 bridge camera boasting a 35x optical zoom. While these two cameras come from very different design philosophies, each offers compelling features for specific user profiles. Having extensively tested both, this article provides a thorough, nuanced comparison to guide you in making an informed choice for your photographic journey.

How They Feel in Your Hands: Size, Ergonomics, and Build Quality

Before you pick up a camera and start firing away, how it sits and feels in your hands can shape your entire experience. The Pentax K-x is an entry-level DSLR with a compact form factor, while the Sony H300 plays the bridge camera role with an SLR-like design.

Pentax K-x: With dimensions of 123x92x68 mm and a weight of 580 grams (including battery), the K-x manages to strike a balance between DSLRs’ typical heft and portability. Its body is polycarbonate with solid feel, and it includes weather-resistant features to a limited extent (though not fully weathersealed). The grip is sculpted for a comfortable hold with ample thumb rest and well-placed control dials, making it suitable for extended shooting sessions without fatigue.

Sony H300: This bridge camera weighs slightly more at 590 grams and measures 130x95x122 mm, the latter figure exaggerated primarily due to the long 35x zoom lens barrel. The body styling mimics DSLRs, but with mostly plastic construction that feels lighter in the grip compared to its size. Its ergonomics are geared more towards photographers used to point-and-shoot cameras, with fixed buttons, no dedicated top screen, and a smaller grip.

In comparative handling, the K-x is superior for users who want DSLR-level tactile control; the H300 favors those prioritizing zoom reach and pocket-ability over long shooting sessions.

Control Layout and User Interface: Directness vs Simplification

The top and rear controls frame the workflow for any photographer, affecting speed and intuitiveness.

The Pentax K-x offers dedicated dials for shutter speed, exposure compensation, and various drive modes - a rarity for entry-level DSLRs of its generation. The rear features quick access buttons to ISO, white balance, and metering. While its 2.7-inch 230k-dot fixed TFT LCD is modest by today’s standards, it provides adequate framing and playback visibility. Unlike newer models, there's no touchscreen capability, so button navigation might feel slightly dated but precise once you’re accustomed.

The Sony H300's control setup is more streamlined, lacking dedicated priority dials like shutter or aperture priority modes, limiting manual exposure control. The 3-inch 460k-dot Clear Photo LCD is more detailed and slightly larger, which aids in composing especially in live view. However, no electronic viewfinder is present, and users must rely entirely on the LCD in bright conditions. The interface simplifies picture taking but restricts granular manual controls, which might disappoint traditionalists.

Sensor Technology and Image Quality

At the core of photographic output lies the sensor - its size, technology, and processing define image fidelity.

Pentax K-x uses a 12.4-megapixel APS-C CMOS sensor measuring 23.6 x 15.8 mm, an impressively large surface relative to cameras in its price range especially back in 2009. As a consequence, it yields excellent image quality with respectable dynamic range and color depth. DxOMark scores reinforce this: an overall of 72, color depth at 22.8 bits, and dynamic range of 12.5 EV stops, making it strong for mid- to low-light shooting.

The Sony H300 opts for a small 1/2.3-inch CCD sensor - the workhorse of many superzooms but limited by physical dimensions (6.17 x 4.55 mm). Despite a resolution of 20 megapixels, the smaller sensor area restricts noise performance and dynamic range, especially beyond ISO 400. No raw shooting is supported. Drastically lower DxOMark data echoes this shortfall; it’s optimized more for casual daytime snaps than professional or low-light shooting.

Real-world take: For portraits, landscapes, and low light, the K-x’s sensor size and raw support provide cleaner images with finer tonal gradations and noise control. The H300 is better suited for bright daylight scenarios where zoom reach matters more than pixel-level image purity.

Autofocus Performance, Accuracy, and Flexibility

Capture moments sharply and fast, and you’ll be a happier shooter.

The Pentax K-x features an 11-point autofocus system with phase detection AF on the DSLR's traditional AF sensor module, complemented by contrast detection focus in live view. The autofocus is quick and reliable under most lighting conditions, with continuous AF available for action sequences. Face detection is included, enhancing usability for portraiture.

Conversely, the Sony H300 uses contrast-detection autofocus only, with a slower, more hesitant response especially under low light or complex subjects. The zoomed-in lens magnifies focusing challenges, leading to occasional hunting with moving subjects. Only single AF mode is supported, and face detection is limited but present. No continuous AF means lost opportunities in sports or wildlife photography.

Image Stabilization and Low-Light Capability

Shoot steady, shoot sharp.

The Pentax K-x incorporates in-body sensor-shift image stabilization compatible with any mounted lens, an advantage for handheld shooting under slower shutter speeds. Its high native ISO range extends to 6400, expandable to 12800, enabling the capture of clean images in low-light scenarios with relatively modest noise. The APS-C sensor's larger pixels play a role here, maintaining detail while controlling noise.

The Sony H300 employs optical image stabilization in the lens, necessary due to its extreme zoom range. This helps minimize motion blur but can’t fully compensate for the sensor’s limitations at high ISO. With a maximum ISO of 3200, noise becomes quite apparent beyond ISO 400. Together with a smaller sensor, its low-light performance is subpar compared to the K-x.

Viewfinder and LCD: Composing Your Shot

Choosing between an optical viewfinder, electronic finder, or LCD screen can influence how you interact with your subject.

The Pentax K-x retains a traditional optical pentamirror viewfinder covering 96% of the frame with 0.57x magnification, delivering a clear, real-time view unaffected by battery life or bright sunlight. This is ideal for many shooters, especially street and landscape photographers who want natural visuals without lag.

The Sony H300 notably lacks a true viewfinder but compensates with a small electronic finder reported at 201k-dot resolution, though it is not bright or sharp by modern standards. Users rely on the 3-inch LCD as the primary composition tool, which can be challenging in high ambient brightness.

Burst Shooting and Continuous Autofocus – Speed Matters

For wildlife and sports, frame rate and AF tracking define success.

The K-x offers 5 frames per second continuous shooting, respectable for its class and era, although autofocus tracking during bursts may lag occasionally. Its 11-point phase detection helps maintain focus for static or moderately moving subjects.

The Sony H300 is limited to a very slow 1 fps burst rate, making it unsuitable for capturing fast sequences. Its AF system does not support continuous tracking or live view autofocus, making it a poor choice for action photography.

Lens Ecosystem and Compatibility

This is where cameras like DSLRs truly shine.

With its Pentax KAF2 mount, the K-x opens access to over 150 autofocus lenses, as well as manual focus options dating back decades. From ultra-wide landscapes to portrait-friendly fast primes or macro optics, this ecosystem provides extensive creative flexibility and often at affordable prices due to the mount’s longevity.

The Sony H300’s fixed 25–875 mm f/3–5.9 lens is versatile for travel and casual zoom-heavy shooting but lacks the ability to swap lenses or customize optical qualities. While convenient and compact, this limits photographic exploration and image quality optimization.

Video Capabilities

Video and stills are increasingly intertwined in modern use cases.

The Pentax K-x records 720p video at 24 fps with Motion JPEG compression. Audio capabilities are limited, and the lack of an external mic port further restricts professional video use. While not its primary strength, the K-x delivers basic, usable footage with manual exposure control.

The Sony H300 supports 720p video at 30 fps, encoded as MPEG-4/H.264, with optical image stabilization aiding handheld recording. It lacks an external microphone input, but includes an HDMI output that can be handy for playback or live monitoring.

For casual video alongside stills, both cameras suffice, but neither aims at serious videography.

Battery Life and Storage

How many shots can you take before hunting for spares?

The Pentax K-x runs on four AA batteries, surprisingly affording about 1900 shots per charge (or set of batteries). This high endurance suits travel and extended shoots without frequent recharging.

The Sony H300 uses a proprietary lithium-ion battery (model unspecified) delivering approximately 350 shots per charge - typical but less convenient than AA replacements in the field.

Storage-wise, both accept SD/SDHC cards, with the Sony also supporting Memory Stick PRO Duo variants, giving flexibility.

Shooting Across Genres: How Do They Stack Up?

Portrait Photography

The K-x’s APS-C sensor and raw format support provide superior skin tone rendition and dynamic range. Its in-body stabilization allows sharper grabs even at slower shutter speeds. Although not equipped with cutting-edge eye detection AF, its face detection and 11 AF points suffice for controlled portraits. The lens ecosystem enables fast primes with beautiful bokeh.

The H300’s fixed lens is not optimally fast (f/3–5.9), limiting background blur. Color rendition and dynamic range are modest, and portrait work may appear flat in lower light.

Landscape Photography

Here, the Pentax K-x stands tall. Its sensor size and dynamic range, paired with manual mode and bracketing options, help capture wide tonal palettes. Weather sealing is limited but better than the Sony. The range of Pentax lenses includes excellent wide-angle optics perfect for sweeping vistas.

Sony’s long zoom is great for distant details but dynamic range and resolution limitations hinder expansive scenes. The fixed lens restricts control over perspective and depth.

Wildlife Photography

Telephoto reach is king: the Sony’s 875 mm equivalent zoom is attractive for distant subjects. However, autofocus lag, slow continuous shooting, and sensor limitations mean many shots are missed or noisy.

The K-x paired with a telezoom lens performs better in AF accuracy and image quality but requires investment in appropriate lenses.

Sports Photography

K-x provides faster burst rate and phase detect AF essential for sports. The H300 simply lacks these, making it impractical for action photography.
