Olympus E-PL6 vs Pentax Optio E85: An Honest Comparison from a Seasoned Camera Tester

As someone who’s put thousands of cameras through their paces over the past 15 years, I often get asked to compare cameras that, on paper, seem like they belong in very different leagues - cameras that couldn’t be more unlike each other yet share similar price points or target entry-level users. That’s exactly the case with the Olympus E-PL6, a 2014 entry-level Micro Four Thirds mirrorless camera, and the Pentax Optio E85, a compact point-and-shoot from way back in 2009.

At first glance, the Olympus E-PL6 looks like a serious step up from the Pentax E85 in almost every spec category (bigger sensor, interchangeable lenses, more manual control). But hold on! This isn’t just a specs face-off. If you’re deciding between these two (or just sorting if upgrading from an E85 is worthwhile), you need the full story based on practical use, image quality, and how each fares across photography styles and modern demands.

Stick with me for a thorough 2500-word deep dive where I’ll unravel the real differences, strengths, and failings of each camera - plus honest recommendations backed by hands-on testing experience.

Physical Size, Handling & Ergonomics: Which Camera Feels Right?

Size and handling often dictate how much fun you have with a camera, and this can be critical if you’re looking for a travel buddy or a discreet street shooter.

The Olympus E-PL6 has a rangefinder-style mirrorless body which feels more substantial and camera-like compared to the miniature Pentax E85 compact. Its dimensions (111x64x38mm) and 325g weight give it decent ergonomics, especially with a grip and clubs-for-thumbs control layout. This size allows more buttons, dials, and a tilting touchscreen that significantly improves usability.

In contrast, the Pentax E85 is ultra-tiny (93x58x24mm) and feather-light at 145g. It's a proper pocket camera designed for absolute convenience but offers very limited physical controls - more akin to a point-and-shoot than anything a serious enthusiast would want for manual creativity.

Atop usability, the Olympus’s tilting 3-inch touchscreen (460k dots) dramatically outshines the Pentax’s fixed 2.7-inch, low-res (230k dots) LCD - making navigation of menus and live-view focusing a real pleasure on the E-PL6.

The Olympus sports a sleek top plate with mode dial, shutter speed, aperture controls, and dedicated buttons, which means quicker access without diving into menus. The Pentax is far more limited: it lacks manual exposure modes and dedicated controls, restricting you to mostly automatic shooting.

Takeaway: If ergonomics and control are a priority (and you can spare the pocket space), the Olympus E-PL6 is the clear winner. The Pentax E85 caters to those who want to “point and shoot” with minimal fuss.

Sensor Size & Image Quality: The Heart of the Matter

You can't talk about digital cameras without the sensor being center stage.

Here’s where we see the real divide:

• Olympus E-PL6 features a 16MP Four Thirds CMOS sensor (17.3x13mm) with a sensor area of 224.9 mm².
• Pentax E85 uses a 12MP 1/2.3" CCD sensor (6.17x4.55mm) with only 28.07 mm² sensor area.

Translated, the Olympus sensor is roughly 8 times larger in area, which drastically impacts image quality - especially in low light, dynamic range, and detail retention. Larger sensors gather more light, resulting in better sharpness, more natural colors, and less noise at higher ISOs.

In real-world testing, shots from the E-PL6 show far richer detail, smoother gradations in skin tones, and significantly better performance in shadows and highlights - ideal for portraits and landscapes.

The Pentax, not surprisingly, struggles in low light and produces softer images with less dynamic range owing to the small sensor and older CCD technology. At base ISO, colors can feel less vibrant, and noise creeps in quickly beyond ISO 400.

Olympus’s advantage is especially evident in RAW capture support, which the Pentax lacks, giving you far more latitude in post-processing for professional or enthusiast workflows.

Lens Ecosystem and Flexibility: How Far Can You Go?

The Olympus’s Micro Four Thirds mount opens a world of possibilities with over 100 native lenses (both Olympus and Panasonic brands), covering everything from fast primes and wide-angle landscapes to serious telephoto reach - plus third-party glass from Sigma and Tamron.

The Pentax E85, on the other hand, comes with a fixed 32-96mm equivalent zoom (3x optical) and a variable aperture of f/2.9 to f/5.2. This is fine for everyday snapshots but strictly limits creative expression.

For those keen on:

• Portraits: Olympus’s fast prime lenses provide gorgeous bokeh and sharpness unattainable on the Pentax.
• Wildlife/Sports: Olympus’s availability of long telephoto zooms paired with sensor stabilization (yes, on the E-PL6) makes it far more capable.
• Macro: Micro Four Thirds has dedicated macro lenses that give you the focusing freedom the Pentax fixed lens simply doesn’t.

Autofocus System Performance: Precision Matters

Autofocus can make or break your shooting experience, especially for action, wildlife, or spontaneous street photography.

The E-PL6’s contrast-detection autofocus with 35 focus points and face detection is surprisingly nimble, managing to track subjects steadily in continuous AF mode at 8 fps burst shooting (impressive for the era). It lacks phase detection but holds up well in daylight and decent light.

Pentax E85’s autofocus is basic contrast detection with a single AF point and no continuous tracking or face detection. Limited to single AF mode with a slow acquisition time, it’s best for static subjects and daylight conditions.

For fast-moving subjects (sports, wildlife), Olympus clearly outperforms the Pentax with faster, more accurate AF and burst capabilities.

Shooting Modes, Exposure Controls, and User Interface

The Olympus E-PL6 offers comprehensive exposure modes:

• Full manual (M)
• Aperture priority (A)
• Shutter priority (S)
• Program auto (P)
• Scene modes
• Exposure bracketing and white balance bracketing

The Pentax E85 offers very basic automation only; it lacks manual exposure modes, exposure compensation, or bracketing features.

Live view on the Olympus is enhanced by the touchscreen interface to select focus points intuitively, while the Pentax’s fixed non-touch screen makes this cumbersome.

Though lacking an electronic viewfinder, Olympus offers an optional EVF, something the Pentax can’t match. The lack of any viewfinder on the Pentax hurts composition flexibility outdoors, especially in bright light.

Build Quality and Weather Sealing: Is Toughness a Factor?

Neither camera is weather-sealed or ruggedized. The Olympus E-PL6 is solidly built with metal and high-quality plastics, while the Pentax is a typical plastic compact.

If you need weather durability, you’d be looking elsewhere, but in terms of daily handling and reliability, the Olympus gives a more reassuring feel built for extended use.

Video Capabilities: Modern Demands Met?

Both cameras are behind the times video-wise, reflecting their release eras.

• Olympus E-PL6 records Full HD 1080p at 30fps, using MPEG-4 and Motion JPEG formats. No 4K, no mic input, no headphones.
• Pentax E85 maxes out at VGA (640x480) resolution - basically barely usable by today’s standards.

Neither camera offers in-body or lens stabilization for video (though E-PL6 uses sensor stabilization for stills), and no advanced video features.

If video is part of your plan, Olympus offers a basic yet watchable option while Pentax is outclassed here.

Battery Life and Storage

Olympus promises around 360 shots per battery charge - respectable for mirrorless but still less than tradition DSLRs. The E-PL6 uses a proprietary BLS-5 battery.

Pentax E85’s battery life is less clearly specified, but compact cameras often last fewer shots, compounded by its small battery.

Both cameras use SD/SDHC/SDXC memory cards, but Pentax also stores images internally (limited capacity).

Photography Genres Breakdown: Who Wins Where?

Let’s get practical: how do these cameras hold up across photography types?

Portrait Photography

Olympus E-PL6 is head and shoulders above thanks to larger sensor, manual aperture control, RAW support, and choice of fast primes for creamy bokeh. Skin tones are natural with better dynamic range. Face detection AF helps nail eye focus.
Pentax E85 struggles with soft images, no manual aperture, and no face detection, resulting in flat, amateurish portraits.

Landscape Photography

E-PL6’s larger sensor and 16MP resolution capture more detail and dynamic range for sweeping vistas. The ability to shoot RAW and exposure bracket enhances post-processing potential. The tilting screen aids composition in awkward angles. Weather sealing would have helped but isn’t available.
Pentax’s resolution (12MP) and tiny sensor deliver noisy shadows and limited dynamic range, making landscapes less impactful.

Wildlife Photography

E-PL6 with interchangeable tele lenses, fast burst at 8fps, and decent AF tracking is usable for casual wildlife. Small size helps with portability in the field.
Pentax E85’s slow autofocus, fixed short zoom, and no continuous shooting make this a non-starter.

Sports Photography

Fast autofocus and continuous shooting are essential here. E-PL6 delivers moderate performance but no phase detection AF or high burst. Still, better than Pentax’s single shot and sluggish focusing.

Street Photography

This is interesting - Pentax E85’s small size and light weight make it extremely discreet and pocketable, great for sneaky shots and low-pressure shooting. However, limited manual control and low-light performance hold it back.
Olympus E-PL6 is light mirrorless with modest size, offering better low light and manual tweaks - but less pocket-friendly.

Macro Photography

Olympus’s ability to switch lenses allows dedicated macros with sharpness and focusing precision. No focus stacking or post-focus but decent sensor stabilization helps handheld shooting.
Pentax fixed lens has a 10cm macro range but weak optical performance and no stabilization hinder close-up work.

Night/Astro Photography

The Olympus excels with higher ISO range (up to 25600), sensor stabilization, and manual exposure. Pentax max ISO 3200 and small sensor limit low-light usability severely.

Video

Moderate advantage to Olympus for 1080p recording - Pentax’s VGA video is practically unusable today.

Travel Photography

Olympus balances versatility with portability - it’s smaller than bulky DSLRs and offers image quality and lens choices. Battery life is fair. Pentax is ultra-compact, ideal as a backup for casual travel but lacks the image flexibility or quality for meaningful travel documentation.

Professional Use

Olympus supports RAW, manual controls, and a flexible lens system, making it usable in semi-pro settings but limited by older AF and lack of weather sealing or high-end codecs. Pentax E85 is entry-level compact only.

Connectivity and Extras: Modern Conveniences?

Olympus E-PL6 supports Eye-Fi wireless cards (Wi-Fi via memory card) and HDMI output, enabling easy external display connections - still handy. No Bluetooth or NFC, reflecting 2014’s tech level.

Pentax E85 offers no wireless features and no HDMI, limiting file transfer options.

USB 2.0 standard on both.

Price-to-Performance: Getting Bang for Your Buck

At launch and even now, Olympus E-PL6 priced around $300 offers serious value for beginner-intermediate shooters who want to explore manual controls, improve image quality, and eventually expand lenses.

Pentax E85 is superseded and mostly phased out, often found for free or under $100 secondhand, making it a basic snapshot tool - but no match for anyone wanting real control or image quality.

Overall Performance Ratings

Let’s look at the overall scorecard summarizing strengths:

• Olympus E-PL6 scores higher in overall image quality, autofocus, controls, and versatility.
• Pentax E85 scores are modest, excelling only in portability and simplicity.

Genre-Specific Camera Scores

Breaking down further by genre:

Clearly, Olympus dominates in portraits, landscapes, wildlife, sports, macro, night shooting, and professional potential. Pentax holds a slight edge only in street photography for discreetness and travel for tiny size.

But be prepared for compromises in quality.

Personal Notes from the Field

Having used both cameras extensively, the Olympus feels like a craftsman’s tool: it invites experimentation, rewarding you with crisp, vibrant images. I often paired it with a 25mm f/1.8 prime for portraits and street shots; the autofocus was speedy enough and the stabilization helpful in dim light.

The Pentax, while fun for pockets and instant snaps, often left me frustrated with noise and lack of control. It’s the kind of camera your grandparents might enjoy for holidays but hardly one for those seeking photographic expression.

That’s the lowdown from my lab, field, and post-production studio. Choosing between these two really comes down to your photographic ambitions - and whether you want to wind up a better shooter or stay a casual photo hoarder.

Happy shooting!
