Overview

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.

Pros & Cons

👍 Pros

  • Interval range of 1 second to 100 hours covers everything from rapid architectural time-lapses to slow environmental sequences over multiple days.
  • Shot count of 1–399 frames plus infinity mode gives precise control over sequence length without babysitting the camera.
  • Autofocus support during intervalometer sequences is a genuine advantage for wildlife and event time-lapses where manual focus is impractical.
  • Replaces the OEM Olympus RM-UC1 at a lower price point while adding timer and interval functionality the original cable remote lacks.
  • 24-month warranty from Fotodiox provides meaningful post-purchase coverage for a field accessory that sees regular use.

👎 Cons

  • Physical cable connection means the remote must remain plugged in for the duration of a long sequence — cable management becomes a factor on multi-hour shoots.
  • The 3L connector is Olympus-specific; this unit does not work with Canon, Nikon, Sony, or other mount systems.
  • No backlit display — programming intervals in low-light or dark field conditions requires a headlamp or supplemental light source.
  • Cable length is not published in available specifications, which may limit placement flexibility if the unit needs to hang free from the camera.
  • AAA battery power means long multi-day sequences risk mid-sequence battery failure if not freshly loaded at the start.

Frequently Asked Questions

Yes — it is a direct functional replacement for the Olympus RM-UC1. It works with a wide range of Olympus bodies including the OM-D E-M1, E-M5, E-M10, PEN E-P1 through E-P5, E-PL2 through E-PL5, E-PM1, E-PM2, and a full range of E-series DSLRs including the E-30, E-410, E-420, E-510, E-520, E-600, and E-620, among others.
Both delay and interval settings are programmable from 1 second up to 100 hours. Shot count runs from 1 to 399 individual exposures, or you can set it to infinity mode for continuous firing until manually stopped.
Yes. Autofocus remains available when using this remote, which is an advantage over manual-focus-only alternatives — particularly useful for time-lapses where the subject distance may shift between frames.
The unit is powered by two AAA batteries, which are included in the box. Battery life will depend on usage intensity, but AAA alkalines are universally available.
It handles both. You can use it as a basic shutter release for single shots and bulb exposures, or engage the timer and interval programming for full time-lapse sequences. The two functions coexist in one unit.
