Ricoh issued a press release about a temporary suspension of firmware update version 2.40 for the PENTAX K-1 and PENTAX K-1 Mark II cameras:

Temporary suspension of firmware update version 2.40 for the PENTAX K-1 and PENTAX K-1 Mark II

RICOH IMAGING COMPANY, LTD. appreciates your continued patronage of PENTAX products.

Please note that the update service of PENTAX K-1 and the PENTAX K-1 Mark II firmware version 2.40 (both released on December 7, 2023) have been temporarily suspended, after some problems have been discovered in the software.

These anomalies include:

• Images cannot be recorded when the ASTROTRACER Type 3 mode is combined with the interval shooting function;
• The SD card slot number indicators on the upper LCD panel flash to indicate that the memory capacity is empty,
  even when some capacity is still available;
• The number of remaining shots available is incorrectly displayed in the viewfinder;
• In the ASTROTRACER Type 3 mode, the exposure countdown on the upper LCD panel advances at unintended moments.

We apologize for any inconvenience which may have been occurred because of these anomalies, and we intend to release revised versions very shortly. Details on the revised versions will be announced as soon as they are finalized. Thank you for your understanding.
