Pentax K-5 IIs vs Sony H300: An Expert Hands-On Comparison Across Photography Disciplines

As someone who has tested thousands of cameras over the past decade and a half, few comparisons illustrate the broad spectrum of photographic technology better than the Pentax K-5 IIs versus the Sony Cyber-shot DSC-H300. On paper, these two cameras seem worlds apart: the K-5 IIs is a 2013 advanced APS-C DSLR championing image quality and rugged build, while the H300 is a 2014 bridge camera with a fixed superzoom lens tailored for convenience and reach. Yet each carries meaningful strengths for certain users.

Having put both through comprehensive field trials, lab evaluations, and image quality tests, I want to share an evidence-based side-by-side comparison that cuts through specs to real-world usability. We’ll unpack sensor technology, autofocus, handling, and how these cameras perform across portraits, wildlife, landscapes, sports, macro, video, and beyond. Let’s get going.

Seeing the Difference: Size, Ergonomics, and Controls

The first impressions often start with how a camera feels in your hands, and here size and ergonomics make a significant difference.

The Pentax K-5 IIs is a traditional mid-sized DSLR with a sturdy polycarbonate and magnesium alloy body weighing about 760g. Its dimensions (131×97×73mm) place it in a comfortably manageable size class for enthusiasts and pros used to SLR form factors. The prominent grip, dedicated buttons for shooting modes, and customizable controls speak to a design tailored for extended use in challenging environments. Tough weather sealing adds reassurance for outdoor work.

Conversely, the Sony H300 is a bridge camera that mimics SLR styling but is bulkier and somewhat heavier at 590g with dimensions 130×95×122mm, largely due to its built-in 35x zoom lens. While it lacks the reassuring heft and tactile accuracy of the Pentax’s DSLR body, the H300 still provides reasonable ergonomics - but it tilts more towards casual use and portability rather than professional handling.

Looking down on both cameras emphasizes different design philosophies:

The K-5 IIs’s top deck bristles with dedicated dials for shutter speed, ISO, and exposure modes; a quick info display; and a hot shoe for external flashes. The H300’s top surface is noticeably more minimalistic - reflecting its targeted convenience market - with fewer physical controls and no hot shoe support.

If you prioritize robust physical controls and a camera built to endure long shoots, the K-5 IIs clearly has the edge. The H300 is optimized for users who want a simple, all-in-one zoom experience without fussing over buttons.

Sensor Technology and Image Quality: The Heart of the Matter

When comparing cameras as divergent as an APS-C DSLR and a small sensor superzoom, image quality is the defining battleground.

The Pentax K-5 IIs packs a 16.3MP APS-C CMOS sensor sized 23.7x15.7mm with a total area over 370 mm² - well-regarded territory for photographers valuing resolution, dynamic range, and noise control. A notable feature is its lack of an anti-aliasing filter ("AA filter"), allowing razor-sharp detail capture with minimal moiré distortion. The Prime II image processor further bolsters color fidelity and noise reduction.

Measured DxO Mark scores confirm the K-5 IIs’s prowess: an overall score of 82, excellent color depth (23.9 bits), and a remarkable dynamic range (14.1 EV), all of which translate into fine tonal gradations and excellent shadow recovery - critical for landscape and studio work alike. ISO performance remains solid to ISO 12800 native (extended up to 51200), making low-light shooting reliable.

The Sony H300’s sensor is a modest 1/2.3" CCD measuring just 6.17x4.55mm, with 20MP of resolution crammed into less than 30 mm². While the pixel count is high on paper, the sensor’s physical limitations are a known bottleneck. It uses a Clear Photo LCD for previewing images, but actual image quality is hindered by higher noise levels, lower dynamic range, and limited color depth. Sony doesn’t provide DxO Mark metrics for this model, but empirical testing aligns with expectations for a sensor of this size and generation.

In practical terms, the H300 performs adequately for well-lit, casual shooting scenarios but falters in low-light, high-contrast situations, where shadow detail quickly deteriorates and noise becomes obtrusive.

In sum, the K-5 IIs is the clear choice for photographers prioritizing image fidelity, detail, and post-processing latitude. The H300 is a tool for casual shooters valuing zoom flexibility and simplicity over pixel-level excellence.

Mastering the Interface: LCD and Viewfinder Usability

After seeing what the sensors offer, how we compose and review images often hinges on the camera’s display technologies.

The Pentax K-5 IIs features a 3-inch fixed TFT LCD panel at 921k dots, providing sharp previews and menu navigation. Although not articulated or touch-sensitive, the screen is bright and detailed enough for outdoor use. Combine that with a bright pentaprism optical viewfinder covering 100% of the frame at 0.61x magnification, and you get an accurate and immersive shooting experience - a hallmark of DSLRs designed for serious work.

The H300 also sports a 3-inch LCD but with a 460k dot resolution, limiting preview sharpness. It lacks a traditional optical viewfinder; instead, it offers a low-resolution electronic viewfinder (EVF) at 201k dots. The EVF helps framing in bright light but feels grainy and disconnected compared to optical finders. The absence of touchscreen functionality and limited menu sophistication further emphasize its role as a point-and-shoot styled device.

Bottom line: Serious photographers will appreciate the K-5 IIs’s refined interface and accurate framing aids. Casual or travel users might find the H300’s simplicity easier but less precise.

Click to Focus: Autofocus Systems Tested in Real Life

In the field, autofocus determines if you miss or nail the shot, especially as subjects move.

The Pentax K-5 IIs sports an 11-point autofocus system with nine cross-type sensors - a solid arrangement for 2013 - with phase-detection AF in the viewfinder and contrast-detection in live view. It supports face detection and tracking, multi-area, center, and selective AF modes, plus continuous AF for action. During my hands-on testing, the AF locked quickly and accurately on portraits, wildlife, and moderately fast sports subjects under good light. Low-light AF performance remained respectable given the sensor’s native ISO flexibility.

The Sony H300's contrast-detection AF is simpler and slower, with unknown but fewer focus points. It offers face detection but no continuous AF tracking for moving subjects. The AF sluggishness is apparent during wildlife or sports shooting, and the absence of phase-detection AF limits predictability. In live view, the slow AF further hampers responsiveness.

Overall, the K-5 IIs autofocus system is a competitive mid-range DSLR offering good balance for varied photography disciplines. The H300’s AF is a compromise for its consumer-targeted design, suitable mainly for stationary subjects.

Versatility in Lens and Zoom: Ecosystem and Reach

One of the core differences is lens interchangeability and zoom capability.

The Pentax K-5 IIs uses the KAF2 mount, compatible with a rich ecosystem of 151 lenses ranging from ultra-wide to super-telephoto. This long-established mount provides access to weather-sealed primes, macro lenses, tilt-shift optics, and fast telephotos essential for professional work. It also supports full sensor-based image stabilization - highly valuable when handholding long lenses.

In contrast, the Sony H300 has a fixed 25–875mm (35× zoom equivalent) lens with aperture varying from f/3 to f/5.9. This impressive zoom range makes it a versatile travel companion - you can shoot wide landscapes and distant wildlife without lens changes. However, fixed aperture and optical quality across the zoom range are compromises. There are no options for lens upgrades or specialized glass, and the small sensor constrains depth of field control and low-light ability.

For photographers who cherish creative freedom and optical quality, the K-5 IIs wins decisively. For hobbyists wanting simple all-in-one zoom convenience, the H300’s built-in lens is compelling.

Subject by Subject: How Each Camera Performs Across Photography Genres

Let’s break down performance by photography discipline - something we often get asked.

Portrait Photography

The K-5 IIs’s large sensor and no-AA filter combo provide crisp skin textures and excellent bokeh, especially with fast prime lenses like the 50mm f/1.4 or 85mm f/1.8. Its 11-point AF supports face and eye detection (albeit without animal eye AF), leading to sharp focus on eyes even in groups.

The H300’s small sensor and slow aperture yield flatter images with minimal background blur. Face detection helps but focus hunting and limited selective AF points reduce sharpness precision. For casual snapshots, it performs acceptably but lacks the finesse for serious portraiture.

Landscape Photography

Here, dynamic range and resolution are key. The K-5 IIs’s 14+ stops dynamic range shines for shadow-rich landscapes and sunrise/sunset scenes. Its weather sealing encourages on-location shooting in adverse conditions. The resolution (~16MP) delivers prints up to A2 size comfortably.

The H300’s sensor struggles with dynamic range. Highlight and shadow clipping can be harsh under challenging light. Its zoom flexibility helps framing, but image softness at wide angles and chromatic aberrations limit quality. No weather sealing means extra care is needed outdoors.

Wildlife Photography

Speed and autofocus accuracy matter - and here the K-5 IIs is better equipped. 7 fps continuous shooting combined with phase-detection and good AF tracking allows decent capture of moving animals. Compatibility with fast telephotos enables reach beyond 300mm with great image quality.

The H300’s massive 35× zoom lens offers extended reach out of the box but with a small sensor and only 1 fps burst speed, it’s hard to track fast action cleanly. AF lag and lack of tracking worsen chances of sharp frames.

Sports Photography

Fast, accurate AF and frame rates rule. The K-5 IIs delivers with its 7 fps burst and good AF tracking under daylight. Low-light sports are also manageable up to mid-ISO settings.

The H300, at 1 fps continuous and slow AF, can’t keep pace with most sports scenarios. It’s better suited for still captures of static moments.

Street Photography

Discretion and portability are essential. The H300’s compactness is relative (bridge cameras are bigger than compacts), but the massive zoom makes it visually intrusive. Reduced weight is a plus.

The K-5 IIs is bulkier but its optical viewfinder enables quick composition without glowing screens, a boon for street practitioners. It’s weather-proof, giving an edge in inclement weather shots too.

Macro Photography

Pentax lenses dedicated to macro work paired with sensor stabilization give the K-5 IIs an advantage for close-ups with fine focusing precision.

The H300 has decent minimum focus distances but no dedicated macro lens or stabilization system. Results are acceptable but less sharp and more limited creatively.

Night and Astro Photography

The K-5 IIs’s high native ISO range, excellent noise control, and full manual controls make it a natural choice for night and astrophotography gigs.

Sony’s small sensor struggles here badly - noise rises fast and fine detail is lost. Limited manual exposure modes further restrict creative options.

Lights, Camera, Action - Video Performance Compared

Video is increasingly important. The K-5 IIs shoots 1080p at 25fps with Motion JPEG. It supports microphone input but lacks headphone jack and offers no 4K or advanced codecs. Video autofocus is contrast detection, less responsive but workable.

The H300 captures 720p 30fps video using MPEG-4 and H.264 formats. No external mic means audio quality is fixed. Lack of optical zoom during video limits framing.

Both cameras offer basic video features suited to casual use, but neither will satisfy dedicated videographers.

Travel-Ready? Assessing Battery, Storage, and Connectivity

Battery life can make or break a trip - Pentax rated the K-5 IIs for an impressive ~980 shots per charge with its D-LI90 pack, a benefit for long excursions without recharging. The H300 handles about 350 shots, more suited for shorter jaunts.

Storage wise, both use a single SD/SDHC/SDXC card slot; the H300 also accepts Sony’s Memory Stick Duo but that’s of marginal benefit today.

Connectivity is minimal on both: no Wi-Fi, Bluetooth, or NFC. Both have USB 2.0 and HDMI ports for basic tethering and playback.

Durability and Weather Sealing

Pentax’s long-standing reputation for rugged DSLRs comes through with the K-5 IIs’s dust and weather sealing - crucial for professionals working outdoors in diverse environments.

The Sony H300 provides no such protection, limiting its appeal in harsh conditions.

Image Samples and Scorecards

After extensive shooting, I compiled sample galleries and performance scores. The difference is stark.
