Olympus E-P2 vs Pentax K-70: A Hands-On Deep Dive into Two Entrylevel Cameras Across the Photography Spectrum

Choosing the right entry-level camera is never a trivial task. Having spent decades testing and reviewing hundreds of models, I know that specs are only the starting point; real-world performance, handling, and how a camera integrates with your shooting style matter just as much. Today, I’m putting two distinct but venerable cameras head-to-head: the 2010 Olympus PEN E-P2 mirrorless camera and the 2016 Pentax K-70 DSLR. Despite being separated by six years and fundamentally different designs, both provide excellent value propositions for photography enthusiasts on a budget.

Let’s scratch beyond the surface and explore how these cameras stack up across all major photography disciplines - from crisp portraits and majestic landscapes to wildlife bursts and cinematic vlogging - all while weaving in hands-on insights and technical analysis. I’ll also give you a clear verdict on which camera suits your creative ambitions best. Let’s get started.

Getting a Feel for It: Size, Build, and Ergonomics

One of the first tangible differences you’ll notice is physical size and handling. The Olympus E-P2 nests comfortably in your hand with its rangefinder-style, compact mirrorless body reflecting classic heritage. Its dimensions are a compact 121x70x36 mm, weighing just 355 g. Meanwhile, the Pentax K-70 is a more traditional DSLR form factor - larger and chunkier at 126x93x74 mm and almost twice the weight at 688 g.

In the field, that size difference means the Olympus feels nimble and discrete, excellent for street photography and travel. Its slim profile fits comfortably into smaller bags, and you won’t feel weighed down during extended handheld shooting. The downside? The smaller grip and rangefinder design don’t offer the same tactile control or rugged assurance you get from the K-70.

The Pentax, on the other hand, shines in build quality and sturdiness. It sports environmental sealing, a rare feature at its price segment, designed to fend off dust and moisture. This robustness lets you shoot confidently outdoors in variable conditions, especially landscapes and wildlife hikes. Its deep grip and larger buttons make for a positive, ergonomic feel, which I particularly appreciated during longer sessions. The tradeoff is the extra bulk and weight, which may be less appealing for travel-centric shooters.

Next, the top control layouts also highlight distinct philosophies - let's dive into how these two cameras organize their controls.

Olympus keeps things minimalist, focusing on exposure dials and fewer dedicated buttons. Pentax’s DSLR approach means more direct controls, including dedicated dials for ISO and drive modes, along with a built-in flash - something the E-P2 lacks. This layout difference translates to quicker adjustments on the K-70, which is welcome in dynamic shooting environments like sports or wildlife.

Sensor, Image Quality, and Processing: Pixels Matter

At the heart of any camera is its sensor, and here the Pentax K-70 clearly outpaces the Olympus E-P2 on paper and in practice.

The Olympus E-P2 features a Four Thirds sized CMOS sensor measuring 17.3x13 mm, delivering a 12MP resolution. Though modest by today’s standards, in its 2010 heyday this sensor offered good image quality with respectable color depth and dynamic range, scoring 21.5 bits and 10.4 EV respectively on DxOMark. It incorporates a built-in sensor-based image stabilization, enhancing hand-held sharpness in low light or at slower shutter speeds.

In stark contrast, the Pentax K-70 sports a much larger APS-C sized CMOS sensor (23.5x15.6 mm) with a 24MP resolution - effectively doubling pixel count and increasing sensor area by roughly 63%. The K-70 lacks an anti-alias filter, giving it an edge in sharpness and micro-contrast, essential for pristine landscape and portrait shots. Pentax’s sensor also offers an extraordinarily high max ISO of 102,400, backed by PRIME MII image processor improvements delivering clean images at high sensitivity.

What does this mean in real-world shooting? The K-70’s sensor produces superior detail fidelity, especially noticeable when cropping or making large prints. Highlights and shadows retain better nuance, crucial in scenes with high contrast such as sunsets or shadowy woods. The higher dynamic range plus lack of AA filter means you can extract a more organic, film-like aesthetic from RAW files.

Olympus’s smaller sensor is no slouch, though. Its stabilized sensor is a boon for handheld macro or low-light photography at night (within ISO limits), and the 12MP files still hold up nicely for web use or moderate print sizes.

On the Back: Screen and Live View Experience

A strong LCD display is vital for framing, reviewing, and adjusting camera settings, especially in the mirrorless and casual user segment.

The Olympus E-P2’s 3-inch Fixed HyperCrystal LCD offers a basic 230K-dot resolution with an anti-reflective coating. The screen displays natural colors and decent brightness but feels somewhat outdated and dim under bright sunlight. It lacks touchscreen or articulation, meaning awkward angles like low or overhead shots slow your workflow. The lack of a built-in electronic viewfinder (an optional accessory) also means relying on the LCD for composition, which is less comfortable in bright environments.

Meanwhile, the Pentax K-70 features a fully articulated 3-inch LCD with an impressive 921K-dot resolution. Its articulation and brightness allow flexible framing in macro work or when shooting video from atypical angles. The interface remains tactile and responsive despite no touch capabilities. Crucially, the K-70 includes a 0.63x optical pentaprism viewfinder with 100% coverage, offering a natural and lag-free shooting experience - valuable for action, wildlife, and street photography where eye-level composition is king.

For those who prefer shooting via optical viewfinder over live view, the Pentax wins hands down. Olympus’s reliance on LCD live view can feel limiting outdoors despite its mirrorless appeal.

Autofocus Systems: Speed, Accuracy and Subject Tracking

Autofocus can make or break your shooting session, especially for wildlife, sports, or unpredictable daylight. Both cameras utilize hybrid AF systems combining contrast detection for live view with additional functionalities.

The Olympus E-P2 features an 11-point contrast detection system, with face detection enabled. Autofocus is reasonably precise for its era but noticeably slow and prone to hunting in low light or low contrast scenes. Tracking moving subjects isn’t its strong suit; continuous AF mode runs at a pedestrian 3 fps burst speed. In real-world terms, this means decent performance for portraits or landscapes, but struggles inserting itself in fast action.

In contrast, the Pentax K-70’s 11-point autofocus system employs phase-detection sensors, nine of which are cross-type. It excels at locking focus rapidly and accurately, even in challenging lighting - an important boon for wildlife and sports photography. The camera handles face detection and tracking better, capitalizing on its 6 fps continuous shooting to capture decisive moments. The hybrid AF system switches smoothly between phase and contrast modes depending on shooting conditions, offering versatility.

When I tested both on bird-in-flight and street sports scenes, the K-70 consistently nailed sharp focus hits while the E-P2 occasionally faltered or lagged.

Sports and Wildlife: Snapping the Fast and the Wild

When chasing action or elusive animals, you want burst speed and reliable autofocus paired with telephoto lens compatibility.

The Pentax K-70’s APS-C sensor’s 1.5x crop factor pairs well with telephoto primes and zooms from the rich Pentax K mount lens ecosystem, currently boasting over 150 native lenses. Combining that with 6 fps burst and solid AF tracking gives enthusiasts a competitive edge. Its weather sealing adds confidence for outdoor adventures.

Olympus’s Micro Four Thirds mount offers a separate, dense lens line-up with 107 native options, including compact primes and stabilized zooms. The E-P2’s sensor-based image stabilization helps keep shots sharp on the move.

However, its burst rate of only 3 fps and slower AF tracking limit success with fast wildlife or sporting exploits. Image quality and resolution also fall short for significant cropping compared to the K-70.

Portraiture: Rendering Skin Tones and Beautiful Bokeh

Portraits require a sensitive sensor for smooth skin tones, reliable face and eye detection autofocus, and supportive lens optics for creamy bokeh.

The Olympus E-P2 benefits from Micro Four Thirds lenses well-known for attractive background blur despite smaller sensor size. Its contrast-detect AF system includes face detection for focus precision on subjects’ eyes. Colors are typically warm and natural, although the sensor’s lower resolution means less detail in intricate textures like hair or fabrics.

Pentax, with its larger sensor and no anti-alias filter, produces exceptional detail and exquisite tonal gradations across skin tones. The DSLR’s optical viewfinder and responsive AF points facilitate quick eye-focused snaps - a must-have feature when working with moving subjects or kids. Paired lenses offer wide apertures ideal for smooth defocus effects, although the higher effective focal lengths (due to 1.5x crop) necessitate wider primes for tighter headshots.

In practice, the K-70 often outdoes the E-P2 for studio or outdoor portraits where detail and subtle color reproduction matter most. Olympus is charmingly capable but requires more manual finesse and less cropping latitude.

Landscapes and Nature: Dynamic Range and Resolution Impact

Landscape photographers often prize high resolution, large sensors, wide dynamic range, and weather sealing for durability outdoors.

Pentax’s APS-C chip again proves advantageous, revealing textures in foliage, rock, and sky with sharpness and fidelity that the E-P2’s Four Thirds sensor struggles to deliver. The anti-alias free sensor lends an almost 3D dimension to scene details. Additionally, the K-70’s weather sealing protects against nature’s elements on adventurous shoots, and its articulated screen facilitates composition from awkward vantage points.

Although Olympus offers sensor stabilization and class-leading compactness for travel, you’ll find landscapes slightly softer with lower dynamic range and less color depth. Still, it retains a certain organic charm appropriate for casual nature photography or travelogues.

Street and Travel: Discretion vs Versatility

For street photography, size, weight, and quiet operation often trump outright speed or resolution.

The Olympus E-P2’s small, rangefinder-inspired build lets it blend easily into urban crowds - less intimidating and more stealthy than a bulky DSLR. Its silent shutter mode helps too, although shutter speed tops out at 1/4000 sec limiting ultra-fast capture. The lens ecosystem’s compact primes further enhance portability.

The Pentax K-70 is simply bigger and louder, a conspicuous companion on city streets. Nonetheless, its ruggedness and higher burst speed enable quicker snaps of fleeting action. The longer battery life (410 versus 300 shots) also supports day-long roaming without recharging.

For travel, the E-P2’s tiny footprint gives it a leg up among those prioritizing ultralight packs, while the K-70 rewards those willing to carry extra weight for superior image quality and battery stamina.

Macro Photography: Focus Precision and Magnification

Close-up shooters demand precise focusing and steady hands or stabilization to capture fine detail.

Both cameras feature sensor-based image stabilization, helpful for handheld macro work. However, the Pentax K-70’s articulated screen is a significant asset for composing tight close-ups from tricky angles. The K-70’s higher resolution also extracts finer detail from macro subjects.

Olympus lacks physical articulation but compensates somewhat with live view magnification for manual focus fine-tuning. Still, I found Pentax’s phase-detection AF and articulated display easier to exploit for complex macro scenes.

Night and Astrophotography: Tackling Darkness

Low-light prowess is critical for events, astrophotography, and moody environmental portraits.

The Pentax K-70 pushes native ISO up to 102,400 and features a stellar low-light AF system capable of acquiring focus in near darkness. Its long shutter speed range (up to 30 sec) and intervalometer support make it a natural choice for night sky and star trail shooting.

Olympus maxes out ISO at 6400, which can be limiting, and has a shorter maximum shutter speed of 60 sec, requiring workarounds for long exposures. While sensor stabilization assists handheld low-light shots, noise and dynamic range limitations become apparent beyond ISO 1600.

Video: Recording Capabilities and Accessories

If you want to dabble in video, the capability gaps widen.

The Olympus E-P2 offers basic HD recording at 720p/30 fps in Motion JPEG - useful for casual clips but dated by today’s standards. No microphone input limits audio quality control.

Pentax K-70 upgrades to full HD 1080p at up to 60i fps, supporting MPEG-4 and H.264 compression. It includes an external mic port for improved sound capture - a boon for serious videographers or vloggers. Neither camera offers 4K video, so those pushing for ultra-high resolution footage must look elsewhere.

Battery Life and Storage: Practical Considerations

Battery endurance becomes more critical the further you roam from power outlets.

Pentax K-70 provides approximately 410 shots per charge, superior to the Olympus E-P2’s 300. Although both rely on proprietary battery packs, the K-70’s longer life supports extended outdoor shoots without swapping batteries.

Both use a single SD card slot; however, the K-70 supports the faster UHS-I standard and SDXC cards, giving an edge in speed and storage capacity.

Connectivity and Extra Features

Connectivity is minimal on the Olympus E-P2, with no wireless features - a reflection of 2010 technology norms. It does feature an HDMI output and USB 2.0 port.

The Pentax K-70 adds built-in Wi-Fi, allowing easy camera control and image transfer to mobile devices - increasingly essential in today’s workflows. GPS functionality is optional via accessory, useful for geotagging landscapes and travel images.

Value and Pricing: What Does Your Dollar Buy?

At their respective launch prices, Olympus E-P2 retailed around $799, while the Pentax K-70 landed at about $649.

Despite being generally more affordable, the K-70 offers significantly more advanced features, better image quality, superior autofocus, weather sealing, and longer battery life. The Olympus’s chief selling point remains its compact, stylish mirrorless design and portability.

If you prioritize size, casual shooting, or street travel, the Olympus still holds charm. But for most photography disciplines, the Pentax K-70 delivers a powerful and versatile package that remains competitive today at reduced used prices.
