The connectivity and features landscape between these two cameras is largely harmonious — both offer Bluetooth 4.2, USB-C, HDMI output, an external memory slot, smartphone remote control, and RAW shooting. Neither provides dual card slots, GPS, or NFC, so for photographers who care about any of those, neither camera has an advantage.
Two specs break the symmetry in opposite directions. The Fujifilm X-E5 supports Wi-Fi 5 (802.11ac) in addition to Wi-Fi 4, while the OM-5 Mark II is limited to Wi-Fi 4 (802.11n) only. In practical terms, Wi-Fi 5 offers faster transfer speeds when offloading images to a phone or laptop on a compatible network — a genuine time-saver for high-resolution files, which matters especially given the X-E5's 40 MP output noted elsewhere. Conversely, the OM System OM-5 Mark II includes pixel shift — a mode where the sensor shifts by sub-pixel increments to capture multiple frames and composite them into a single ultra-high-detail image. This is a meaningful creative tool for still-life, landscape, and studio photographers willing to work from a tripod.
The two differentiators serve distinct shooting styles: faster wireless transfer favors active photographers moving files constantly in the field, while pixel shift targets precision shooters in controlled environments. Neither benefit is universally superior, but for the broadest range of users, the X-E5's Wi-Fi 5 advantage has more routine utility, giving it a narrow overall edge in this group.
