Aputure AP_TR-3S Remote Shutter Timer Intervalometer Olympus RM-UC1

The Aputure AP_TR-3S is a wired intervalometer and shutter release designed as a full functional replacement for the Olympus RM-UC1. Where the OEM cable release handles only basic remote shutter triggering, the AP_TR-3S adds a programmable timer with delay settings from 1 second to 100 hours, interval control across the same range, and shot count programming up to 399 frames — or continuous infinity mode. Those numbers mean that whether you're shooting a 400-frame sunset sequence at 10-second intervals or a multi-day slow-motion cloud study firing every 30 minutes, the unit has the range to handle it without modification. Autofocus remains active throughout, which separates this from manual-focus-only cable releases and makes it viable for subjects that shift in distance between frames.

In the field, this remote is a compact, battery-powered accessory that attaches via the camera's dedicated remote port and requires no additional software or pairing. The compatibility list spans a broad range of Olympus bodies — from the OM-D E-M1 and E-M5 to the PEN series and legacy E-system DSLRs — making it a single purchase that covers multiple bodies in an Olympus-based kit. It is particularly well-suited to astrophotographers running long bulb sequences, macro photographers needing camera-shake-free triggering, and wildlife and landscape shooters building time-lapse libraries. The included AAA batteries and 24-month Fotodiox warranty round out a package that punches well above the OEM remote's capability at a comparable or lower price.
