Yesterday I included the above crop in my post about a potential issue during long exposures with the Fujifilm GFX50S. There were a few plausible suggestions in the GFX Owners Group relating to a defect, but after more testing, none of them seem to be the problem. There is supposed to be one other similar image on the web from a GFX at this time so maybe it’s a fluke.
I continuously shot long exposure last night for about 4 hours before my battery died. My only complaint is that, when the camera is processing noise reduction, there is no countdown timer to tell how long is left.
The lack of a count down while the camera is processing the noise reduction profile isn’t really a problem with short exposures, but when you are waiting around for 8 or more minutes it makes you question if the camera has locked up.
It’s also important to keep an eye on the battery when shooting long exposure, because the camera could die while processing the noise reduction profile after a long exposure. The last one I took actually took longer to process than my walk home and shortly after the camera finished my battery died.
