Pentax K-5 vs Sony Cyber-shot H300: An Expert’s In-Depth Comparison for Every Photographer’s Needs

When it comes to cameras that span very different categories - an advanced DSLR like the Pentax K-5 and a bridge superzoom like the Sony Cyber-shot H300 - comparing them is as much about understanding the distinct photographic philosophies they embody as it is about raw specifications. Over the past 15 years of testing thousands of cameras, I’ve discovered that the best choice depends heavily on what kind of photography you do, how much control you want, and where you shoot.

In this article, we’ll break down these two cameras from every angle - sensor tech, autofocus, ergonomics, lens systems, real-world performance, and more - helping you see clearly which is the smarter investment for your style and budget.

Let’s start with the basics.

First Impressions: Size, Design, and Handling

At a glance, the Pentax K-5 and Sony H300 look like they belong to different photographic families. The K-5 is a mid-size DSLR boasting 740 grams of solid build and classic SLR ergonomics. Its dimensions (131x97x73mm) make it fairly compact for a DSLR, yet it offers a substantial grip and robust control layout designed to facilitate extended shooting sessions without fatigue. In contrast, the Sony H300 is a bridge-style superzoom camera with SLR-like styling but significantly lighter at 590 grams and bulkier in depth (130x95x122mm).

The deeper barrel on the H300 is a giveaway of its massive zoom lens. For those who prize portability, the K-5 feels more balanced in the hand with its pentaprism optical viewfinder and top-plate exposure info. The H300 leans more toward a casual shooter’s comfort, with fewer physical controls and more instincts-based operation.

Diving deeper, the top control layouts reveal Pentax’s professional heritage versus Sony’s consumer simplicity:

The K-5 features multiple dials for shutter speed, ISO, and exposure compensation, plus dedicated buttons for AF modes and metering. Sony’s H300 pares back those options with a mode dial and fewer direct-access buttons, relying more on menus and auto modes.

In short: If manual control and tactile responsiveness motivate your photography, the K-5 dominates. If you prefer a grab-and-shoot superzoom for casual shooting, the H300 stands out.

Sensor and Image Quality: APS-C Excellence Meets Small Sensor Limits

Most photography enthusiasts understand that sensor size plays a tremendous role in image quality. The Pentax K-5’s 16MP APS-C CMOS sensor is a tried and tested performer, capable of delivering excellent dynamic range, high resolution (4928x3264 pixels), and respectable high ISO performance. Its sensor area of 372mm² substantially surpasses the tiny 1/2.3-inch CCD sensor in the Sony H300, which maxes out resolution at 20MP (5152x3864) but from just 28mm² sensor area - a size that inevitably limits image quality.

In real-world terms, this gap manifests in sharpness, low-light prowess, and noise control. The Pentax’s DXO Mark scores confirm this empirical reality: an overall score of 82, color depth of 23.7 bits, dynamic range at 14.1 EV, and usable low-light ISO up to 1162. The Sony H300 isn’t DXO tested, but based on sensor tech and user feedback, expect considerably less dynamic range and higher noise at anything beyond ISO 400.

The real kicker is the anti-aliasing filter on both cameras, which slightly softens images but controls moiré. Because the K-5’s sensor is significantly larger, it compensates for this softer effect gracefully; the H300’s smaller sensor simply struggles to resolve fine details cleanly.

When shooting landscapes or portraits where image quality is paramount, the Pentax clearly dominates.

Live View, LCD, and Viewfinder Experience

The K-5 offers a 3-inch, 921K-dot fixed TFT LCD. While not articulating, its display is crystal clear and brightly backlit, making it easy to review images and navigate menus in bright conditions. The advantage is furthered by the optical pentaprism viewfinder with 100% coverage and 0.61x magnification - ultimate for manual focusing and framing critical compositions.

The Sony H300 provides a similar-sized LCD (3 inches) but at less than half the pixel density (460K). For casual shooters, this is fine - but pixel peepers and those wanting precise manual focus confirmation will find it less satisfying. Notably, the H300 lacks an optical viewfinder; instead, its electronic finder offers only 201K resolution with no coverage metric stated, which can today feel dated and less reliable in bright sun.

Thus, the Pentax offers a more professional interface, supporting critical manual work and prolonged shooting, while the H300 is oriented toward point-and-shoot convenience.

Autofocus Systems: Precision vs Simplicity

The autofocus system is one lens through which you can evaluate how seriously a camera takes focus speed and accuracy.

The Pentax K-5’s Hybrid AF system combines 11 phase-detection points (9 cross-type) with contrast detection in live view mode. It offers continuous AF, single AF, face detection, and multi-area AF, the kind of sophistication you expect in an advanced DSLR. This means subjects are tracked competently, and manual focus aids are supported smoothly.

The Sony H300’s AF is contrast-based only, no phase detection, with no continuous AF or liveview AF. It includes face detection but with fewer focus points and slower lock times. This isn’t surprising given the H300’s consumer-grade positioning and fixed lens design.

Practically, this means wildlife and sports photographers will find the Pentax more reliable for quick-moving subjects, while the Sony’s AF suits static and casual shooting.

Burst Shooting and Shutter Performance

Fast shutter speeds and shooting rates are paramount for action genres.

Pentax’s K-5 shutter speeds range from 30 secs to 1/8000 sec, enabling the freezing of rapid motion and use in bright light with wide apertures. Its 7fps continuous shooting means you can burst shoot moving children or animals without missing key moments.

Sony’s H300 maxes out at 1/1500 sec shutter speed and only 1fps burst. The slow max shutter speed and minimal frame rate means limited utility for sports or fast action.

For photographers needing high shutter speed and rapid captures, the K-5 is a clear winner.

Lens Ecosystem: Depth vs Convenience

The Pentax K-5 uses the KAF2 lens mount, compatible with over 150 lenses ranging from vintage primes to modern professional telephotos. This versatility is invaluable for landscape, portrait, macro, or specialist lenses, offering creative expansiveness.

In contrast, the Sony H300 features a fixed 35x zoom lens (25-875 mm equivalent, F3-5.9 aperture range). For many casual users, this covers a practical focal range from wide-angle to super-telephoto, but it’s a jack-of-all-trades lens with optical compromises: softer edges at long focal lengths and limited low-light capacity.

So if you want to invest in glass over the long term, the Pentax is the camera to grow with.

Build Quality and Weather Sealing

One feature enthusiasts appreciate about Pentax DSLRs is their weather-resistant body construction. The K-5 offers environmental sealing that resists dust and moisture, making it highly dependable in tough outdoor conditions typical of landscape or wildlife photography.

The Sony H300, lacking any weather sealing, is best sheltered for indoor or fair-weather shoots. This limits its longevity and reliability in demanding environments.

Battery Life and Storage Flexibility

Battery life can be a deciding factor for travel and all-day shooting.

With the D-LI90 battery, the Pentax K-5 achieves approximately 980 shots per charge, a strong figure consistent with DSLRs that don’t rely heavily on power-hungry LCDs or EVFs. Sony’s H300, with a smaller battery and older tech, manages just 350 shots per charge, which demands carrying spares for extended sessions.

Both cameras accept SD/SDHC/SDXC cards; however, the H300 also supports Sony’s Memory Stick Duo types - a legacy convenience for existing Sony users.

Video Capabilities

Both cameras offer video, but are fundamentally different in capability.

The Pentax K-5’s video specs are 1080p at 25fps, using Motion JPEG codec. While it can capture full HD video, limitations include non-electronic shutter and moderate codec efficiency - -typical for early DSLR video.

The Sony H300 records 720p video at 30fps, using modern MPEG-4/H.264 codecs. It lacks a mic or headphone port, but its smaller file sizes and quicker encoding suit casual video sharing better.

Neither camera supports 4K or advanced video features, so serious videographers will look elsewhere.

Specialized Photography Disciplines: Strengths and Weaknesses

Let’s consider how these cameras stack up in specific photography types, rounding out their suitability beyond specs.

Portrait Photography

The K-5’s large sensor excels here. Better skin tone rendering, smooth bokeh via lens choice, and 11-point AF with face detection boost portrait results significantly. In contrast, the H300’s sensor struggles with skin tone subtlety and background separation due to small sensor limitations and lens constraints.

Landscape

Dynamic range and resolution are king. The K-5 delivers strong dynamic range (14.1 EV) ensuring highlight and shadow details preservation. Weather sealing means shooting in various environments with confidence. The H300, while convenient with a wide lens at 25mm equivalent, cannot match dynamic range or detail granularity.

Wildlife and Sports

Fast autofocus and burst rates give the K-5 a clear edge for tracking moving subjects. Coupled with telephoto lens options, it serves wildlife and sports photographers well. The Sony H300’s superzoom lens grams reach the long end, but slow AF and burst limit its action credentials.

Street Photography

Street shooters value discreteness and portability. Here the H300’s smaller weight is a plus, though the K-5 remains relatively compact for a DSLR. Electronic noise from larger sensor autofocus systems can sometimes cause delays, but the K-5 also offers more manual control. For low-light street scenes, K-5’s ISO performance will outperform the H300.

Macro Photography

Here lens compatibility is critical. The K-5 supports dedicated macro lenses with precise focusing and possible focus stacking workflows. The H300 has no dedicated macro mode or lens options, giving it limited close-up possibilities.

Night and Astrophotography

Low noise and long exposures are challenges requiring sensor sensitivity and shutter accuracy. The K-5’s ability to shoot at ISO 12800 (boosted) plus 30s max shutter suits long-exposure shots. The H300’s max ISO of 3200 and lack of long exposure modes limit this use.

Connectivity and Extra Features

Neither camera offers wireless connectivity (Wi-Fi, Bluetooth, NFC), a point where both feel outdated today.

Physical connectivity includes USB 2.0 and HDMI ports on both; the K-5 has a microphone port for basic audio input in video, the H300 has none. The K-5 also benefits from optional GPS units.

Price-to-Performance Overview

Currently, the Pentax K-5 hovers around $800 while the Sony H300 costs approximately $250, reflecting their very different market segments and usage cases.

This price gap mirrors differences in sensor quality, build, control, and lens ecosystem depth - the K-5 is a serious tool, while the H300 is a budget-friendly superzoom.
