Dark-time with different cameras - Bobu - 2019-12-22 The idea of this thread is, that everybody can post the measured dark-time of their cameras. That way we can get an overview, which cameras are suited for which timelapse-applications. To have a common understanding, I use the following definition for dark-time: The dark-time is the difference between the interval time and the exposure time. During the dark-time the camera must save the picture on the SD card and, depending on the camera settings, show the image on the display and/or accept manual changes of exposure parameters (and/or transfer the image to an external device). If the time necessary to do these operations is longer than the available dark-time you will either loose frames or block these operations. Therefore in the context of this thread, the definition of dark-time is the shortest available dark-time for your camera where you don’t lose frames and are still able to do all the necessary operations for a certain setting. Slight variations of the interval time during a sequence are considered o.k. while lost frames or continuously blocked operations are classified as fails. I will start with the Sony A7SII: Intervalometer Pro Timer, Auto Review Off, no operations, Electronic Shutter => Dark-time: 0.3-0.5 sec. Intervalometer Pro Timer, Auto Review Off, no operations, Mechanical Shutter => Dark-time: 0.4-0.7 sec. Intervalometer Pro Timer, Auto Review 2 Sec., manual adjustment of exposure time and/or ISO, Electronic Shutter => Dark-time: 2.5 sec. Intervalometer Pro Timer, Auto Review 2 Sec., manual adjustment of exposure time and/or ISO, Mechanical Shutter => Dark-time: 3.7 sec. Intervalometer Pro Timer, Auto Review Off, manual adjustment with ControlMyCamera App of exposure time and/or ISO => Dark-time: 2.5 sec. Intervalometer internal PlayMemories TL App, M-Mode or A-Mode => Dark-time: ~ 0 sec. You can find more details about the testing-procedure on my blog: https://wild-places.com/2019/12/22/time-lapse-photography-with-sony-a7sii-interval-exposure-time-and-dark-time/ Please add the results of your cameras in this thread. RE: Dark-time with different cameras - Gunther - 2019-12-23 I find it interesting that Sony seems to prioritize the image preview in a way that it delays dark time. With Nikon as soon as the next trigger comes, the image preview will be dismissed which I find better. But good to know: in any case, I recommend to turn off image review. RE: Dark-time with different cameras - Bobu - 2019-12-23 With Sony the image preview is also dismissed with the next trigger but it nevertheless leads to longer dark-times. What are the dark-times of the current Nikon cameras? |
