Panasonic Lumix G85 vs. Pentax K-5 IIs: A Thorough Comparison for the Serious Photographer

Choosing the right camera is a pivotal decision for any photography enthusiast or professional. Over my 15+ years testing numerous digital cameras across genres, I’ve come to appreciate the subtle strengths and compromises inherent in every model. Today, I’m putting two noteworthy advanced-level cameras head-to-head: the Panasonic Lumix G85, a Micro Four Thirds mirrorless body announced in 2016, and the Pentax K-5 IIs, a 2013 mid-size DSLR with an APS-C sensor. Though they hail from different eras and design philosophies, both carved out loyal followings due to their solid feature sets and image quality.

In this deep dive, I’ll assess these cameras through a comprehensive lens - covering sensor technology, autofocus, handling, shooting performance, and suitability across multiple photography disciplines. Whether you’re shooting portraits, wildlife, sports, or cinematic video, by the end you should have a clear sense of which camera fits your style and budget. Let’s begin by sizing up their physical design and ergonomics.

Size, Ergonomics, and Physical Handling: Practical Considerations Matter

The Panasonic G85 embraces the modern mirrorless form factor, designed as a compact “SLR-style” body, while the Pentax K-5 IIs is a traditional DSLR with a bulkier, more substantial frame.

Panasonic G85 vs Pentax K-5 IIs size comparison

At 128 x 89 x 74 mm and roughly 505 grams, the G85 is noticeably smaller and lighter than the K-5 IIs, with dimensions of 131 x 97 x 73 mm and a heftier 760 grams. This isn’t surprising given the Pentax’s DSLR mirror and pentaprism design, compared to the G85’s electronic viewfinder and mirrorless construction.

Ergonomically, the K-5 IIs offers a more substantial grip and dedicated top-dial controls - a boon for photographers with larger hands or those who prize direct, tactile interaction. In contrast, the G85’s grip is comfortable for extended handheld shoots but feels more streamlined.

From my experience shooting for extended periods, the K-5 IIs’s bulk pays off with fatigue reduction and button placement. However, the G85’s lighter form delivers distinct advantages for travel and street photography, where discreetness and carry comfort count.

Next, we’ll examine the control layout and viewfinder experience - critical factors for on-the-fly adjustments.

Control Layout and Viewfinder: The Photographer’s Command Center

The physical design must marry with effective control ergonomics to streamline shooting. I tested both cameras extensively to see which offers faster, more intuitive handling.

The Pentax K-5 IIs impresses with a dedicated top LCD panel and dual command dials, allowing instant exposure and ISO changes without diving into menus. These traditional DSLR controls are reassuring for experienced photographers who prefer manual fiddling. The optical pentaprism viewfinder provides a clear, lag-free image, critical when tracking fast-moving subjects.

On the flip side, the Panasonic G85 adopts a fully digitized and customizable interface, featuring a fully articulated 3-inch touchscreen that rivals some dedicated monitors. Touch-to-focus and menu navigation feel responsive, and the electronic viewfinder (EVF) offers 100% coverage with a sharp 2.36M-dot resolution.

While some purists dislike EVF latency or electronic noise, the G85’s EVF delivers vivid color and useful overlays like histograms, focus peaking, and zebras - things optical finders can’t match. However, the G85’s control dials are fewer and smaller, balancing accessibility versus minimalism.

If you prize direct, tactile controls and a clear optical viewfinder, the K-5 IIs stands out. If, however, you want the flexibility of a high-resolution EVF combined with touchscreen versatility for creative shooting, the G85 is compelling.

Now, how do their imaging engines compare? Sensor size and quality directly influence your image fidelity.

Sensor Technologies and Image Quality: Size and Detail Matter

Both cameras utilize 16-megapixel CMOS sensors but differ significantly in size and processing tech, which shapes dynamic range, noise, and resolution.

Panasonic G85 vs Pentax K-5 IIs sensor size comparison

The Pentax K-5 IIs’s APS-C sensor (23.7 x 15.7 mm) is substantially larger than the Lumix G85’s Four Thirds sensor (17.3 x 13 mm) - about a 65% larger sensor area. APS-C sensors have an edge in gathering light and controlling depth of field, generally yielding better image quality in challenging conditions.

Pentax’s K-5 IIs also drops the anti-aliasing filter (“AA filter”), trading potential moiré for slightly crisper detail - a strategy that rewards careful technique and high-quality lenses. The DxO Mark scores echo this: an overall 82 vs. the G85’s 71, with the Pentax delivering wider dynamic range (14.1 vs 12.5 EV) and superior low-light sensitivity (ISO 1208 vs 656). This translates to cleaner high ISO shots and richer shadows in varied lighting, which I confirmed in side-by-side test shoots.

Meanwhile, the G85 shines with modern sensor optimizations, including 5-axis in-body stabilization, enabling sharper handheld photos even in dim light. It supports RAW and multiple aspect ratios including square formats, while the K-5 IIs sticks to the traditional 3:2 ratio.

For landscape and portrait photographers who prize exquisite detail and tonal latitude, the K-5 IIs remains a potent tool despite its age. Conversely, the G85’s sensor, while smaller, benefits from newer processing to hold its own in versatility and color rendition, especially when stabilized shooting and video are prioritized.

With sensor and handling assessed, the autofocus system defines responsiveness across genres.

Autofocus Systems: Precision, Speed, and Tracking

Autofocus (AF) technology is the heartbeat of any camera. It drives your success in fast-paced genres like wildlife, sports, or street. I conducted repeated autofocus challenges, ranging from static portraits to moving subjects.

The Panasonic G85 employs a contrast-detection AF system with 49 focus points distributed across the frame and supports face-detection autofocus with touch-to-AF. It lacks phase-detection AF, which limits continuous- and low-light performance somewhat. However, Panasonic integrates 4K photo modes and post-focus bracketing that harness the sensor and processor cleverly for focus stacking and selection after capture.

In contrast, the Pentax K-5 IIs features a hybrid AF system with 11 phase-detection points (9 cross-type). Phase detection generally delivers faster acquiring and tracking speed - something I noticed immediately when photographing moving wildlife and sports. The K-5 IIs’s AF is more reliable for predictive tracking, especially under tricky lighting.

While the G85’s burst rate of 9 fps beats the K-5 IIs’s modest 7 fps, the latter’s AF is often more consistently locked on during prolonged bursts. This nuanced difference plays out in the field - I’d trust the K-5 IIs for high-speed natural history or action work; the G85 might occasionally hunt focus in dim environments but compensates via more sophisticated video AF and 4K modes.

Neither camera offers animal eye-detection or the latest AI-driven AF found in recent models, but each remains competitive for enthusiasts.

Build Quality and Environmental Durability: Weather Sealing in the Real World

Build quality is critical for photographers working outdoors or in adverse conditions. Both cameras boast weather-resistant designs but with some caveats.

The Panasonic G85 features a sealed magnesium alloy body designed to fend off dust and moisture, though it’s not marketed as fully waterproof or freezeproof. The DSLR-style body offers a comfortable, secure grip during rapid deployment.

Similarly, the Pentax K-5 IIs offers robust seals and a rugged chassis, tested extensively by pros in harsh climates. Being older, it lacks humidity or drop certifications but behaves solidly in wet or dusty environments. Pentax has long championed weather resistance, which qualified it for fieldwork with careful handling.

Personally, I found that the K-5 IIs’s more substantial body instills confidence during challenging hikes, while the G85’s lighter body encourages packing extras but demands cautious weather consideration.

LCD Screens and User Interface: Flexibility vs Tradition

Screen quality influences your framing, manual focus confirmation, and menu navigation. The G85’s fully articulated touchscreen versus the K-5 IIs’s fixed TFT LCD represents a generational leap.

The G85’s 3-inch, 1040k-dot articulated screen lets you flip out and rotate the display for high-angle or selfie shots - perfect for vlogging or macro work. Touch input speeds up AF point selection and camera setup, which I found valuable in fast-paced settings.

Meanwhile, the Pentax K-5 IIs has a fixed 3-inch screen at 921k dots, which is sharp but less versatile. It lacks touchscreen capabilities and relies on physical buttons for navigation.

For photographers regularly composing off-center or shooting video, the G85’s LCD gives substantial creative freedom, whereas the K-5 IIs’s straightforward display suits those who prefer optical viewfinder dominance.

Lens Ecosystem and Compatibility: The Mount Matters

A camera’s potential is closely tied to lens availability and variety, an area of fundamental importance to serious photographers.

The Panasonic G85 uses the Micro Four Thirds mount, benefiting from an extensive system shared with Olympus. With over 100 native lenses, including primes, zooms, macros, and specialty lenses, it boasts impressive versatility. Third-party manufacturers also support the format, making it excellent for diverse genres like street, video, or macro.

Conversely, the Pentax K-5 IIs relies on the Pentax KAF2 mount, supporting a wide selection of both modern autofocus and legacy manual focus lenses. Pentax offers around 150 lenses, including renowned weather-sealed primes, excellent macros, super-telephoto zooms, and tilt-shift lenses for critical work. The larger APS-C format pairs well with these glass options, delivering excellent sharpness and bokeh.

In practice, users who want a compact, adaptable kit for travel or video might prefer the Micro Four Thirds lens ecosystem. If your priority is rugged, high-quality optics for demanding outdoor or studio applications, the Pentax mount remains a very strong contender.

Battery Life and Storage: Endurance for Extended Shoots

For many photographers, battery life can make or break a long shoot or travel photography trip.

The Pentax K-5 IIs excels here with an impressive CIPA rating of 980 shots per charge, thanks to its DSLR design optimized for power conservation. This endurance is highly valued for events, wildlife shoots, or extended field sessions where charging options may be limited.

In contrast, the Lumix G85 offers a modest 330 shots per charge, typical for mirrorless cameras with electronic viewfinders and LCD use. However, the G85 compensates with a USB charging option and smaller batteries, making it easier to carry spares.

Regarding storage, both cameras use single SD cards supporting SDHC and SDXC standards. Neither offers dual card slots, a downside for professionals needing immediate backups.

Video Capabilities: The Panasonic G85’s Edge

Video has emerged as a key consideration even for stills shooters. The Lumix G85 clearly outshines the K-5 IIs in this area.

The G85 supports 4K UHD (3840 x 2160) at up to 30 fps, along with Full HD 1080p at 60 fps. It offers advanced features like 4K Photo mode (extracting 8MP stills from video) and 5-axis in-body stabilization, which significantly smooths handheld footage. Audio input via microphone jack enables higher-quality sound capture for serious video work.
