Bulb exposure can be performed until the battery is completely drained of power.
IMPORTANT: Noise may increase on the images recorded with long exposure times.
NOTE: When noise reduction is turned on, noise reduction processing is performed on images where the exposure is at least one second long. The processing is performed after the shutter closes and takes the same amount of time as the exposure. During this time, another picture cannot be taken. However, when shooting an image with a long exposure time, if there is insufficient battery power after the exposure, noise reduction will not be performed and the photograph will be saved without performing noise reduction.
