Panasonic Lumix G85 vs Pentax Efina: A Deep Dive for the Discerning Photographer

When it comes to choosing a camera that fits your style, needs, and workflow, the landscape of options can be... overwhelming, to say the least. Today, I’m rolling up my sleeves to pit two very distinct contenders head-to-head: the Panasonic Lumix G85, an advanced mirrorless camera released in late 2016, and the Pentax Efina, a rather petite ultracompact travel buddy from mid-2013.

On paper, these cameras might not seem comparable - they serve quite different purposes and were made for drastically different users. But therein lies the fun and usefulness of a frank, experience-rich comparison: it forces us to analyze practical tradeoffs, real-world performance, and which camera genuinely deserves your hard-earned money.

So buckle up. I’ve personally handled thousands of cameras over 15+ years, putting them through their paces under various shooting conditions and genres - and I’m ready to share everything you need to know about these two.

Getting Hands-On: Size, Build, and Handling

Let’s start with a tactile experience: picking up the cameras and feeling how they mesh with your hand.

First impression - the G85 is an SLR-style mirrorless camera with a reassuring weight of 505 grams and dimensions roughly 128×89×74 mm. That means it has a solid hand grip, plenty of dials, and enough heft to feel balanced, even with heavier lenses. Its body is weather-sealed, a bonus for landscape and wildlife photographers who brave the elements. As someone who has lugged cameras through rainforests and dusty deserts, having that reliability gives peace of mind.

In contrast, the Pentax Efina is a true ultracompact marvel, weighing just 91 grams and barely larger than a large deck of cards at 87×54×21 mm. Its sprint-light size screams portability, slipping effortlessly into jacket pockets or tiny bags. However, the tradeoff is clear - this camera is no speed demon on handling. Without a dedicated grip or complex buttons, you lose some tactile precision and manual control. For a casual stroll or quick snapshots while traveling light, though, it shines.

Design Philosophy: Controls and User Interface

After feeling the bodies, the logical next step is how these cameras interact with their users - the ergonomics of buttons, dials, and screens.

The Panasonic G85 boasts a classic top plate loaded with physical controls: dual command dials, dedicated exposure compensation, and mode dials all within thumb and forefinger reach. The layout is thoughtfully spaced and intuitive, letting you adjust settings on the fly - crucial for dynamic shooting situations like sports or wildlife. The illuminated buttons, while sparse, keep things functional without unnecessary clutter. Trust me, having manual exposure modes (shutter/aperture priority, full manual) at your fingertips without diving into menus is a workflow game-changer.

Contrast this with the Pentax Efina, whose fixed, minimalistic control scheme is tailored towards point-and-shoot simplicity. There’s no manual exposure - no shutter or aperture priority - just auto modes with some exposure tweaking here and there. The tiny buttons and lack of touchscreen can feel limiting, especially if you crave granular control. Its 2.5-inch fixed QVGA LCD doesn’t help much with navigation either, being quite low resolution and non-articulating.

Sensor Size & Image Quality: The Heart of the Matter

No comparison between cameras is complete without discussing sensor architecture and resulting image quality - because, at the end of the day, that’s why we invest in these tools.

The Lumix G85 employs a Four Thirds CMOS sensor measuring 17.3×13 mm - a modest mid-sized sensor by today’s mirrorless standards but significantly bigger than compact cameras. It churns out 16 megapixels without an anti-aliasing filter, leading to crisp images that strike a commendable balance between resolution and noise control.

On the other hand, the Pentax Efina uses a tiny 1/2.3" CCD sensor (6.17×4.55 mm) with 14 megapixels. This sensor’s physical area is less than an eighth of the G85’s - a telling limit on raw image quality. Smaller sensors generally struggle with noise at higher ISO, limited dynamic range, and decreased depth-of-field control.

When I tested both cameras side-by-side shooting landscapes at base ISO, the difference was apparent. The G85 delivered images with far richer tonal gradations - vibrant but natural colors, excellent shadow detail, and superb dynamic range (~12.5 EV according to DXOMark). Meanwhile, the Efina’s photos lacked that punch, exhibiting noticeable noise creeping in above ISO 400 and colors that felt muted. The Pentax also struggled to hold highlight detail in bright scenes - no surprise considering the modest sensor tech.

For portraits, G85’s sensor size and lack of AA filter help generate smoother skin tones and better bokeh, while the Efina’s small sensor coupled with a slow max aperture (f/3.5 to 6.3) results in generally flat backgrounds and less subject separation.

In a nutshell: if image quality is a priority beyond point-and-shoot snapshots, the G85 is the clear winner.

Viewing and Composing Your Shots

Screen and viewfinder quality affect how easily you frame and check exposures - something often overlooked until you’re out in tricky light.

The Panasonic G85 sports a bright 3-inch, 1040k-dot fully articulated touchscreen, enabling flexible angles for low or high framing - perfect for macro or street photography. Touch functionality extends to focusing and menu navigation, offering speed and convenience. Additionally, the 2360k-dot electronic viewfinder covers 100% of the frame with 0.74x magnification. As someone accustomed to shooting with optical viewfinders, I still find this EVF reliable; its refresh rate and clarity make manual focus and precise composition straightforward.

The Pentax Efina, by contrast, has no viewfinder at all. Its fixed 2.5-inch QVGA screen, while acceptable for casual framing, struggles in bright outdoor conditions and lacks articulation, hampering flexibility for creative angles. This limits compositional control and can be frustrating during extended shooting sessions.

Autofocus and Performance: Speed, Accuracy & Tracking

Here’s where the G85 flexes its muscles, built with enthusiast and semi-pro users in mind.

Panasonic designed the G85 with a contrast-detection-only autofocus system featuring 49 focus points. While some rivals flaunt hybrid phase-detection systems for faster tracking, Panasonic managed to optimize the G85’s AF to achieve 9 fps continuous shooting with AF tracking - impressive for the time and sensor class.

In practice, the AF was snappy and accurate under good lighting. Face detection worked reliably, making portraits more efficient. However, animal eye AF was not present, a feature increasingly sought for wildlife shooters.

The Pentax Efina’s autofocus is contrast-based but much simpler and less robust. It offers a center-weighted AF area, no continuous or tracking AF, and slower response times. In bright conditions, focusing was mostly fine for casual snaps, but under dim light or moving subjects, the system struggled noticeably.

For sports or wildlife photography, G85 is clearly in another league; the Efina is better seen as an ultra-compact casual shooter.

Lens Ecosystem & Flexibility

One of the G85’s greatest assets is the Micro Four Thirds lens mount. Panasonic’s native line-up alone boasts over 100 lenses from ultrawide primes to long telephotos with image stabilizers - plus Olympus lenses share compatibility, adding to options.

In contrast, the Pentax Efina is fixed-lens, paired with a 26-130mm equivalent f/3.5-6.3 zoom. While versatile for travel snapshots and casual zooming, it lacks the creative potential of interchangeable optics and generally yields slower apertures, making challenging light tougher.

This difference typifies the cameras’ design intentions: the G85 supports serious photographic exploration; the Efina prioritizes convenience and light packing.

Image Stabilization

The G85 features sensor-based 5-axis image stabilization, highly effective in minimizing shakes during handheld shots and video. From my experience, it extends usable shutter speeds by 3-4 stops - invaluable for low-light landscapes or stabilized video work without gimbals.

The Efina relies on digital stabilization, which typically crops or degrades image quality. Panasonic’s hardware stabilization aligns better with professional expectations.

Video Capabilities

In today’s hybrid world, video features can tip the scales.

The G85 comfortably shoots 4K UHD at 30fps with H.264 codec, 100 Mbps bitrate, and includes built-in mic input - key for quality sound capture. It supports in-camera 4K Photo modes letting you extract 8MP stills from video, plus time-lapse recording and manual exposure during video.

The Efina tops out at 720p HD video - adequate for brief clips, but hardly professional-grade. No microphone input or advanced encoding options exist.

A filmmaker or vlogger would find G85’s video flexibility far superior; the Efina’s limitations confine it to casual use.

Battery Life and Storage

The Panasonic G85 offers roughly 330 shots per charge in CIPA standards, typical for mirrorless cameras with EVFs engaged. From my repeated tests using Wi-Fi and EVF, this proved sufficient for full-day outings, but extra batteries are handy for extended trips.

The Pentax Efina, with its small sensor and minimal electronics, rated around 200 shots per battery - enough for a day’s worth of snaps but nowhere near the endurance expected of enthusiast cameras.

Both use SD card storage with single slots; no remarkable differences here.

Connectivity and Extras

The G85 includes built-in Wi-Fi for instant image transfer and remote shooting via smartphone apps - a feature I used frequently during assignments to speed up client previews. It lacks Bluetooth or NFC, which has become more standard since its release but remains functional.

By contrast, the Efina offers no wireless connectivity, amplifying reliance on USB transfer.

Durability and Weather Sealing

An often overlooked but crucial aspect - how tough is your camera in the wild?

The Panasonic G85 features weather sealing against dust and moisture, enabling shoots in less-than-ideal conditions without worry. I personally took mine hiking in the rain and dry, dusty environments with zero issues. The built-in flash and hot shoe further augment versatility.

The Efina has no sealing or ruggedness claims - designed for gentle urban or travel use - meaning you’ll want to treat it more delicately.

Pricing and Value Proposition

This is where the comparison veers off the beaten path.

When launched, the G85 hovered around $900 body-only - a competitive price point for an APS-C/micro four thirds enthusiast mirrorless model with 4K video, stabilization, and weather sealing. Used or discounted now, it offers strong value with its robustness and versatility.

Now, here’s the kicker: the Pentax Efina is still commonly available for under $10. Yes, ten bucks - literally. If you want an almost-free pocketable camera for snapshots or as a simple backup without fuss, this little guy is almost a no-brainer.

But the Efina delivers best when expectations align with simplicity and casual point-and-shoot photography. The G85 demands a higher investment but rewards with control, image quality, speed, and futureproofing.

Photography Disciplines: Who Rocks What?

To truly help you decide, let’s survey their usability across my main photography genres.

Portraits

The G85’s larger sensor, no AA filter, face detection, and fast lenses can render pleasing skin tones and separation. The Efina’s limited aperture and small sensor struggle to isolate subjects or generate creamy bokeh.

Landscapes

Thanks to weather sealing, 16MP resolution, and dynamic range >12 EV, the G85 shines in capturing nuanced wide scenes. The Efina lacks detail, struggles with highlights/shadows, and is vulnerable in rough conditions.

Wildlife

Fast AF, 9fps burst, and access to telephotos makes the G85 capable for birders and casual wildlife shooters. The Efina’s slow focusing and tiny sensor make it limited to static subjects.

Sports

Continuous AF tracking and decent frame rates place the G85 in the amateur sport shooter camp; the Efina can’t keep up.

Street

The Efina’s pocketability is a plus for street photographers desiring discretion - the G85 is bulkier but more responsive.

Macro

G85’s articulating screen and focus stacking are a boon; the Efina’s minimum focus is 20cm, limiting creative macro work.

Night/Astro

The G85’s ISO range and manual modes lend nicely to low-light and astropohtography with tripod use. The Efina’s sensor and lens limit available light capture.

Video

Panasonic’s 4K and mic input wipe the floor with the Efina’s VGA max resolution and absent audio ports.

Travel

Both have merits: Efina’s ultra-light for light packing; G85’s versatility suits diverse scenarios.

Professional Work

Only the G85 fits here - raw support, file quality, and workflow compatibility.
