Olympus E-M10 II vs Ricoh GXR Mount A12: A Deep Dive into Two Unique Entry-Level Mirrorless Cameras

When browsing for an entry-level mirrorless camera, you might stumble upon some unexpected options. Today, I’m diving into a somewhat unconventional pairing: the Olympus OM-D E-M10 II, a Micro Four Thirds system camera, and the Ricoh GXR Mount A12, a modular APS-C system with a fixed lens unit. Though both claim entry-level mirrorless status, these two cameras approach photography in remarkably different manners. Having extensively tested thousands of cameras across genres over the years, I’m excited to share my practical, hands-on insights comparing these machines head-to-head.

Throughout this review, we’ll explore technical specs, real-life performance, and usability - not only on paper but in scenarios that matter to photographers like you and me. Let’s get started by looking at their physical design and ergonomics.

Handling and Design: Classic Micro Four Thirds vs. Compact Modular System

Before plunging into performance, the feel of a camera in your hands can make or break the experience. The Olympus E-M10 II sports a traditional SLR-style mirrorless body with pronounced grips and intuitive controls. Meanwhile, the Ricoh GXR Mount A12 has a rangefinder-inspired, compact design with modular elements - a rather unusual concept where the sensor and lens come combined as a unit you swap.

As you can see in the size comparison, the Olympus is slightly thicker but offers robust ergonomics with a good grip and well-placed dials, especially beneficial for prolonged handheld shooting. At 390 grams, it’s lightweight but still substantial enough to feel secure. The Ricoh, weighing in a bit lighter at 370 grams, means you’re holding a camera closer to a slim compact or a rangefinder. Its boxy shape and smaller hand grip make extended shooting sessions feel different. If discretion and compactness are your priorities - think street and travel photography - the Ricoh excels. However, if comfortable handling with physical controls is your thing, especially during fast action or longer shoots, the Olympus is a more satisfying companion.

Let’s dig deeper into the controls and interface.

Control Layouts and User Interface: Intuitive or Minimalist?

The Olympus E-M10 II boasts a well-thought-out physical interface with dedicated dials for shutter speed, exposure compensation, and easily accessible buttons for ISO, white balance, and drive modes.

Reviewing the top view above, note the Olympus’s two control dials - one at the front and one at the rear - along with a handy mode dial. This lets you seamlessly switch between aperture-priority, shutter-priority, manual, and program modes without diving into menu jungles. Plus, customizable buttons speed up workflow.

Contrast this with the Ricoh GXR, which largely relies on fewer physical controls and a more minimalist approach. It lacks a proper electronic viewfinder built-in (EVF must be added as an optional accessory), and its buttons are sparser.

For photographers who value quick access and manual control, Olympus’s interface clearly edges out. But for those comfortable with a pared-back control experience, especially beginners or street shooters who prefer to keep their setup simple, the Ricoh’s minimalist design could be charming.

Now that you know how these cameras feel in hand and at your fingertips, it’s time to consider their most important feature: the sensor and image quality.

Sensor Technology and Image Quality: Four Thirds vs APS-C

Sensor size plays a crucial role in image quality, dynamic range, noise performance, and bokeh characteristics. The Olympus uses a 16-megapixel Four Thirds sensor measuring 17.3 x 13 mm, whereas the Ricoh GXR Mount A12 sports a 12-megapixel APS-C sensor measuring 23.6 x 15.7 mm.

From the sensor size comparison, you can see the APS-C sensor on the Ricoh is substantially larger, giving it a bigger surface area for light capture. This generally translates to better image quality, especially in low light, and improved shading and depth-of-field control.

But sensor size isn't the whole story. The Olympus E-M10 II incorporates the TruePic VII image processor, providing solid color reproduction, decent dynamic range (measured at 12.5 EV by DxO Mark), and a respectable maximum native ISO of 25600. The Ricoh’s sensor, although slightly older technology (2011), retains good color depth and natural skin tones, but with a lower maximum ISO of 3200, its low-light prowess is more limited.

In my real-world shooting, Olympus’s images show pleasing exposure latitude and manageable noise even at ISO 1600–3200, while Ricoh’s files shine in daylight and controlled lighting but begin to falter when pushing ISO above 800. Note also that the Olympus uses 16MP, offering a resolution advantage for printing or cropping, albeit modest compared to current standards.

Regarding raw format, both support raw capture, essential for serious editing, but Olympus provides a more mature raw processing ecosystem within its OM-D series, compatible with popular software such as Adobe Lightroom and Olympus's own Workspace app.

Let’s see how this translates into actual photos.

Comparing Sample Photos: Color, Sharpness, and Detail

Here’s a gallery of direct samples from both cameras, shot side-by-side under similar conditions:

Right away, Olympus displays deeper tonal gradation and slightly more punch in colors without appearing oversaturated, excellent for portraits and landscape work. The Ricoh’s output is softer with a gentler color palette, which could appeal to those looking for more neutral tones straight from the camera.

Sharpness at base ISO appears comparable, but Olympus’s 16MP resolution provides finer detail retention, especially at 100% viewing size on screen. The lesser resolution the Ricoh offers may be less suited for large prints or heavy cropping.

Until this point, Olympus shows a clear image quality lead fuelled by its newer sensor technology and processor. But how do these cameras perform when it comes to autofocus - an area often decisive for many photographers?

Autofocus Systems: Precision vs Speed

The Olympus uses a contrast-detection autofocus system with 81 focus points, including face detection and tracking, along with continuous and single AF modes. The Ricoh employs a contrast detection AF as well but has fewer AF point data and lacks face and eye detection features.

In testing, Olympus’s autofocus is snappier and more consistent, especially in continuous AF and tracking modes. Animal eye AF is unavailable on both, but the Olympus face detection helps with portrait focus lock, reducing the need for manual fine-tuning.

Ricoh’s AF felt slower and more deliberate, requiring patience in low contrast or dynamic scenes. For static subjects or deliberate composition, it works fine, but for fast-moving subjects - wildlife or sports - it tends to lag.

If autofocus speed and accuracy matter - say, for event coverage or action photography - Olympus’s system is more advanced and reliable.

Build Quality and Weather Resistance: Ruggedness Matters?

Neither camera offers environmental sealing, waterproofing, or ruggedization, which is common at this price point. Olympus’s build quality, however, feels more robust with a metal chassis, lending confidence in rough conditions.

Ricoh’s modular design presents a sturdy feel but is simpler and shows more plastic in its construction. The modular lenses/sensors may appeal to those who like system flexibility, though this adds complexity and cost long-term.

Build-wise, Olympus provides a stronger, more resilient tool for demanding usage.

Display and Viewfinder Comparison: Composition Tools

Both cameras feature 3-inch screens, but the Olympus offers a tilting touch-enabled screen with 1.04 million dots resolution, while the Ricoh GXR has a fixed 920K dots screen without touch.

I appreciate Olympus’s tilting screen flexibility, especially for creative angles like low or high shots, or video framing. Touchscreen focus selection and menu navigation add speed and convenience.

Ricoh’s fixed screen limits compositional creativity somewhat and requires button navigation for settings, which feels sluggish in comparison.

Regarding the viewfinder, Olympus has a built-in electronic viewfinder with 2.36 million dots coverage at 100%, whereas Ricoh offers no built-in EVF; an external EVF is optional, adding bulk and cost.

For those relying on an EVF for stability and eye-level shooting, Olympus wins hands down.

Burst Shooting and Buffer: Which Takes Action Better?

If you shoot sports, wildlife, or action, continuous shooting speed is crucial. Olympus delivers an impressive 8 frames per second (fps) with autofocus tracking. Ricoh caps out at 3 fps, and without AF tracking, limiting action potential.

Olympus’s generous buffer allows several seconds of high-speed shooting before slowing, ideal for moments that unfold quickly. Ricoh’s more modest buffer reduces burst duration.

So, for dynamic shooting scenarios, the Olympus is the practical choice.

Video Capabilities: HD Recording and Functionality

With video becoming ever more important, here’s how these two fare:

• Olympus E-M10 II: Full HD 1080p at up to 60fps, using H.264 codec, including support for 720p and 480p. It offers built-in 5-axis sensor stabilization, a huge plus for handheld video. However, no microphone or headphone jack is provided.

• Ricoh GXR: Limited to 720p HD at 24fps with Motion JPEG (MJPEG) format, which results in larger files and less efficient compression. No in-body stabilization or audio ports.

If video is a meaningful aspect of your work or hobby, Olympus is clearly more modern and functional. The in-body stabilization specifically helps smooth handheld footage without needing expensive lenses.

Lens Ecosystem and Compatibility: System Potential

Olympus belongs to the expansive Micro Four Thirds system with over 100 native lenses from Olympus, Panasonic, Sigma, and others. This means you have an impressive array of primes, zooms, macros, and specialist optics at many price points and sizes.

The Ricoh GXR Mount A12’s unique modular design combines sensor and lens into a unit. While this offers a curious approach with interchangeable units, it significantly limits lens choices to those modules Ricoh produced - and that selection is very small today. In other words, you’re stuck with what was available during its production cycle.

If flexibility and long-term growth potential are priorities, Olympus’s MFT system wins easily here.

Battery Life and Connectivity: Staying Powered and Connected

Both cameras use rechargeable lithium-ion battery packs with similar rated lifespans: Olympus scores around 320 shots per charge; Ricoh 330 shots. Real-world results align closely.

Connectivity-wise, Olympus features built-in Wi-Fi, allowing easy image transfer, remote control, and basic sharing on mobile devices. Ricoh offers no wireless features.

In the age of social media and instant sharing, Olympus’s wireless convenience is advantageous.

Size, Weight, and Travel-Friendliness

Looking again at physical dimensions:

Olympus is a bit chunkier but remains pocketable with compact lenses. The Ricoh is slimmer but lacks the versatility and often-famous Micro Four Thirds lens/user support system.

For travel photography, Olympus’s balance of size, performance, and feature set positions it well for most users, while Ricoh’s unique design might appeal to niche shooters wanting unusual system modularity in a small package.
