## Description

Product Description time lapse vid The best interval shutter release for time-lapse and astro The LRTimelapse PRO Timer 3 is one of the most advanced and flexible camera interval triggers for time-lapse and astro photographers . Small and lightweight with a built-in Li-ion battery , the timer can be charged via micro-USB and lasts up to 20 hours per battery charge! It has a crisp OLED display that is readable in all conditions and a single button for extra easy and ergonomic operation - even in the dark and with gloves on. Small, light and enormously flexible The LRT PRO Timer's small and lightweight housing can be attached directly to the camera's hot shoe (or via corresponding eyelets on the tripod ) at two different angles! The timer can trigger two cameras at the same time , supports mirrorless cameras and offers a torch function for foreground lighting - it also enables timed and periodic shooting, and above all: the shortest possible black times . So the camera can be operated without any problems while shooting! Flexible settings and different modes Intervals can be set in 0.1-second increments. Interval ramping enables stepless interval adjustment over an adjustable time period during shooting - even in combination with motion control hardware! Optionally, a Bulb mode (astrophotography) is available for time-lapse and single exposures . The timer illumination can be switched off ! Default values for interval, number of exposures, etc. can be saved in the LRT PRO timer settings.

This ensures an improved feel and durability that can withstand even rough handling in a camera bag Modern charging via USB-C to USB-C: The charging circuitry has been completely redesigned and now supports USB-C charging.

Review: Impressive Tool - This is a great little product. Crammed full of features and very well designed. It’s very easy and intuitive to use. It doesn’t come with a cable so you’ll have to source this yourself, but it in theory will be compatible with any camera provided you can get a cable for it. It works perfectly with my Sony A7RV. It’s very small and lightweight but is well constructed so seems pretty durable. It’s not cheap, but worth the money vs competitive products given how well it’s made. If I had one complaint it’s that the internal clock isn’t very accurate and drifts a little fast after only a few days.
Review: A phenomenal external interval trigger oozing quality - This is a tiny, extremely light, but mighty intervalometer with some well thought out options and great ergonomics especially for those very cold days where gloves are a necessity. The housing is light but durable unique plastic and the display is excellent. What sets this apart from the usual cheap generic models is the the short black mode releasing control of your camera allowing you to adjust critical settings between shots.

## Features

- The LRT PRO Timer 3.5 is one of the most advanced and flexible camera interval meters ever developed. It was developed by Gunther Wegner, a pioneer of time-lapse photography, and "Made in Germany" specially designed for the discerning time-lapse and astrophotographer.
- The intervalometer can operate two cameras simultaneously, allows timed and periodic time-lapse recording, has a special setting for mirrorless cameras, a flash function to illuminate the foreground, and most importantly: it works super fast by eliminating unwanted delays caused by the autofocus signal.
- The intervals can be adjusted in increments of 0.1 seconds. The interval ramp allows a smooth transition of the interval over an adjustable period of time - this also works with motion control hardware. Interval values, number of recordings to be recorded, etc. can be stored in the settings of the LRTimelapse PRO 3.5.
- Operation is easy (even with gloves) thanks to the rotary knob and the high-contrast OLED display, which is easy to read in all conditions. The Li-ion battery is USB rechargeable and the device can be mounted on the hot shoe in two different ways.
- The trigger cable required for operation is not included and must be purchased separately.

### ⭐⭐⭐⭐⭐ 出荷検品が不十分です。→交換していただきました。
*by 一***者 on 20 May 2022*

製品自体はすばらしいものです。 シャッター制御用の2.5mmジャックが2系統ありますが、届いた製品で確認すると2番めのジャックにプラグを挿入しようとしても奥まで入りませんでした。動作テストを全品していれば気付ける不良ですね。 購入後１番目しか使っていなくて同様の不良に気づけず、いざ２番めも使おうとするときこれに気づくという悲劇を防ぐためにも、購入者には受け取り後の確認をおすすめします。 →連絡したところ先出しで良品を発送してくださり、今後改善するとのことでしたので評価は２から５に変更しておきます。
