Pro Timer 2.5: LRTimelapse Introduces the Ultimate Intervalometer Packed with Advanced Features

The creator of LRTimelapse recently announced the release of the Pro Timer 2.5, the most advanced intervalometer available on the market. Here are the main features and specifications of this next level time-lapse tool.

Serious time-lapse photographers probably know Gunther Wegner, the creator of the LRTimelapse software that allows to post-process and remove flickering in day to night and night to day sequence (also called the holy grail). This time, the German engineer addressed another long time issue in the time-lapse community: the lack of proper intervalometer specifically designed for the most demanding conditions. This statement may sound strange since internet is flooded with cheap options for intervalometer and shutter release. Unfortunately, most of these devices are not really designed for time-lapse work and suffer from numerous issues such as: 

  • Poor battery life;
  • Bad user interface;
  • Reliability issue;
  • Lack of sub-second interval setting;
  • But most importantly, unnecessary signal delay sent to the camera.

This last point is critical because basic intervalometers tend to send a two signals to the camera. First, an auto-focus signal, then the proper triggering signal. But the first AF signal is not useful for time-lapse capture. Why is this so important? Because in certain conditions, each second is critical when shooting a time-lapse and wasting precious time with an unnecessary step delays the entire operation.

This wasted AF signal time could be used instead to preview the image exposure, adjust the settings between two shots, or program a shorter interval. Therefore, by shortening the AF signal to the minimum, the photographer can focus on other aspects. This is precisely what the LRTimelapse Pro Timer 2.5 does. However, the AF signal is not entirely removed from the triggering sequence because some cameras, especially the mirrorless ones, need to receive an AF signal before taking a picture. Sending the trigger signal alone would not work on these cameras. But GuntherWegner reduced this signal to the bare minimum in order to save time.

Here are some of the key features of the LRTimelapse ProTimer 2.5: 

  • Very fast shutter release with no unnecessary delays due to autofocus signals.
  • Intervals can be defined in 0.1 second steps instead of one second minimum on most intervalometers (external an internal)
  • Easy user interface on a OLED display, can be operated with gloves. Display can be turned off and the entire device can be light free (no light contamination).
  • Settings can be stored (preset).
  • Camera can be operated in Bulb-Mode for longer exposure times than 30 seconds. That's useful for astrophotogaphy.
  • Recording of unlimited images or a predefined amount of images is both possible.
  • Dual trigger port to connect two cameras at the same time.
  • Dual hot shoe mounts, which allow you to attach it at two different angles.
  • Broad compatibility with any camera where a standardized analog release cable is available for (2.5mm TRS port). Full support for mirrorless cameras via a special wake-up feature which prevents losing shots when the camera goes to sleep mode.
  • Countdown indicator on the screen to show when the next pictures will be taken. Very useful for hyper-lapse shooters.
  • Long battery life thanks to the built in Li-Ion Battery which is recharged via Micro-USB. The LRTimelapse Pro Timer can be powered via an external USB powerbank.

The Pro Timer 2.5 is available for $239.

I have LRT and have been using it for a few years now. Gunther has also helped me troubleshoot issues I have run into in years past. While I know he has been wonderful in the timelapse community and some of the features this intervelometer offers are wonderful, $239 vs $19 for the industry norm is quite the jump. Granted, I’m not surprised based off of where Timelapse+ was priced. I just don’t know if a .9 difference in interval is really that dramatic for 95% of the people out there looking for an intervelometer. Plus, the 1 dial, while novel, sounds like you’d need to carry the instructions with you every time you plan to use it.

I've had the Pro Timer since it came out. It couldn't be simpler to operate (no instructions required), the single dial makes it quick and easy no matter what you're trying to accomplish ... it also gets amazing battery life, has tons of features, and costs substantially less than its main competitor (for which it represents a far better value).
The OLED screen is stunning, easily visible in bright sunlight, and can even be used as a flashlight at night. It also dims right down to almost nothing, but because it's OLED, the screen remains crisp and clear even at its dimmest setting.
I've got half a dozen cheap intervalometers, and other than maybe using one of them for a remote shutter release sometime down the road, I've tossed the rest of them into a storage container with no intention of ever accessing them again.
Combined with the LRT software package, this is THE time lapse package to get for fixed tripod time lapse work.

I don’t know about you, but I have never had an issue with battery life with my intervelometers.

I think this rig and the timelapse+ rig are headed in the right direction. For someone who shoots a lot of day to night timelapses for work, flicker from aperture priority sucks and the ability to bulb ramp is a big desire. This doesn’t offer that the way timelapse+ does, but all the reviews on timelapse+ sound like it was not quite where it should be.

The article doesn't make particularly clear that the ProTimer is tightly integrated with qDslr Dashboard (ControlMyCamera on the App Store). The level of direct control over bulb ramping using the software and the Pro Timer is far in excess of anything Timelapse+ offers, although it does require the use of an iPad along with the ProTimer.
Full manual control, or a feature called Auto-Holy-Grail can make the bulb ramping as detailed, or as easy as you like.
It's quite a large oversight that the author didn't mention this super tight integration between the qDslr Dashboard software and the LR ProTimer for Holy Grail work in the article, I'm quite surprised actually ... it's one of the biggest features when using the LR ProTimer.

A huge oversight. That’s amazing that it would be left out. But I guess the video doesn’t really touch on it and honestly I am surprised

It's a shame after all this time we can't get C1Timelapse as well as LRTimelapse. I abhor using LR and no matter what I do it's just so clunky and bloated (even on a fast NVME drive, 8 core CPU, and a 2080), it makes processing timelapses impractical for me. Using C1 everything is instantaneous and no to minimal lag, colours and tones are better and I can export 100's of images in minutes, instead of 20-30+ in LR (and PC becomes unusable).

Still this might be of use if the ramping is smooth enough. I have found the Nikon's new built in intervalometer with exposure smoothing to be sufficient + some video deflickering but this could be promising

Having used LR Timelapse since Gunther first made it available ... I have come to believe that the integration between LR Time-lapse and Adobe Lightroom is so complex and so interdependent ... I doubt we'll ever see anything from Gunther being made available for C1.
But I too would love to dump Lightroom for good ... the only machine left running the standalone version of .v6 is my time-lapse computer, an older Mac I let chug away in the back room rendering time-lapse projects.

I use LRT too, but the pricing of the latest one has totally put me off. This to be honest looks to have some useful features but for the price it really should be built a LOT better. It's all getting too expensive Gunther...
