1Dx LCD playback delay

Vfrifrcfi — Fri, 01 Dec 2023 08:35:03 GMT

Have a 9-15 second delay for processing between when a photo is taken and the playback on LCD screen. Unable to take back to back single shot photos during this delay even with playback turned off.
Any fixes?

Do you perhaps have any lens corrections turned on? If so, the camera needs time to process the corrections before the embedded JPEG is created.

Are you shooting long exposures, more than 1 second? If so then it could be the long exposure noise reduction setting in the camera is set on, or auto.

Long exposure noise reduction works by taking a second exposure after the picture that is the same exposure time as the photo, but with the shutter curtains closed to create a black image. The camera then uses the black image as a map of the noise and subtracts it from the image before writing to card. This means you cannot view the image until the dark frame exposure is captured and the noise processing completed. If your shutter speeds are between 9 and 15 seconds this would account for the delay.

Another good possibility.
