On the surface, the OM-5 and E-M1X could not be more physically different - yet both embrace Olympus’s signature SLR-style mirrorless aesthetic. The OM System OM-5 is remarkably compact and lightweight at just 414 grams and dimensions of 125x85x50 mm. This camera’s manageable footprint and hand-friendly grip make it an ideal travel companion and everyday shooter. The fully articulated 3-inch touchscreen also facilitates flexible shooting angles, teamed with solid single-handed usability.

Contrast that sharply with the E-M1X, which tips the scale at a hefty 997 grams and measures a substantial 144x147x75 mm. Its body is chunkier, featuring a dual grip design optimized for vertical shooting - catered towards professionals who demand ruggedness and long sessions in challenging conditions. Although bulky, the E-M1X remains well balanced, especially with longer telephoto lenses.

Both bodies offer weather sealing, enduring rain and dust - though neither is freezeproof or shockproof by specification. Personally, I found the OM-5’s lighter build favored street and travel photography, whereas the E-M1X’s robust construction made me more confident in wildlife and sports scenarios.

Let's take a look at their top controls and interface real-estate next.

Control Layout and User Interface: Streamlining Professional Precision

Olympus cameras strike a fine balance between tactile controls and menu navigation. The OM-5 adopts a simplified yet effective layout, including a mode dial smartly integrating custom modes along with standard PASM options. The absence of a top LCD screen does sacrifice some instant feedback but keeps the camera sleek.

The E-M1X, conversely, indulges users with a more complex control scheme, featuring two top LCD screens, dual memory card slots, two control dials (front and rear) both horizontally and vertically, and customizable buttons galore. It’s the kind of rig that rewards photographers who master its layered access - improving workflow during action-packed shoots.

Both cameras employ high-resolution 2360-dot electronic viewfinders (EVFs) with 100% coverage; however, the E-M1X edges out slightly in magnification at 0.74x compared to the OM-5’s 0.68x, providing a marginally larger viewfinder image that I appreciated during critical focus work.

Sensor & Image Quality: Same Footprint, Different Processing Potential

At heart, both cameras share the 20-megapixel Four Thirds sensor (17.4x13 mm) with an effective resolution of 5184x3888 pixels, and both maintain the familiar 4:3 aspect ratio (though OM-5 offers 1:1, 3:2, and 16:9 options as well).

The sensor technology employs a conventional CMOS design including an anti-aliasing filter, which balances moiré suppression with sharpness. Maximum native ISO tops at 25,600, starting from a base of ISO 200, extending down to a boosted ISO 64 in the OM-5. Both models support raw capture.

However, the OM-D E-M1X’s dual TruePic VIII processors grant it superior computational prowess. I saw this translate into slightly smoother image rendering, better noise control at higher ISOs, and improved dynamic range in real-world scenarios, especially noticeable in shadow recovery during landscape shoots.

The OM-5 uses a single processor unit (model unspecified), which is fast and capable but a notch down in throughput. That said, image quality differences in base ISO shots are quite subtle, and the OM-5 still delivers stunning, clean results suitable for large prints and professional work with less aggressive post-processing.

Autofocus Systems: The Race for the Fastest and Most Reliable Lock

Both cameras boast 121 focus points with hybrid phase-detection and contrast-detection autofocus - an Olympus hallmark. Their autofocus systems include face detection, eye detection (for humans), continuous AF, single AF, and tracking modes.

Despite their shared AF architecture, the E-M1X has a definite advantage in speed and tracking accuracy, attributable to its dual processors and refined AF algorithms tailored for high-intensity shooting. In the field, while the OM-5 comfortably locked focus on portraits and landscapes, it sometimes shuffled focus points in low contrast or rapidly moving subjects.

For wildlife and sports, the E-M1X is a beast, delivering up to 60 fps continuous shooting (mechanical shutter) with full AF/AE tracking versus the OM-5’s more moderate 10 fps. This disparity is a clincher for photographers who can justify the bulk for capturing fast action.
