Nikon has released a substantial firmware upgrade for the Nikon D5 camera, while the Pentax K-1 Mark II receives a minor update.

Firmware Version C:1.30 for the Nikon D5 makes the following changes from the previous firmware (V. 1.21):

. Added  Recall shooting functions  to the functions that can be assigned to camera controls. Holding the selected control recalls previously-saved exposure settings (including shutter speed and aperture), a feature that can for example be used to switch rapidly between scenes that require different exposures.

Recall shooting functions  can be assigned to the following controls using Custom Setting f1 (Custom control assignment):  Preview button,  Fn1 button,  Fn2 button,  AF-ON button,  Sub-selector center,  AF-ON button for vertical shooting, and  Lens focus function buttons. It can also be assigned to the Fn button on a WR-1 or WR-T10 remote control using the  Assign remote (WR) Fn button  option in the  SETUP MENU.

For more information, see the addenda to the User’s Manual available from the Nikon Download Center (Nikon Download Center > D5 > Manuals >  Supplementary Firmware Update Manual).

. Fixed the following issues:

– If  Backup  or  RAW Slot 1 – JPEG Slot 2  was selected for  PHOTO SHOOTING MENU  >  Role played by card in Slot 2  in http server mode, the shutter would sometimes not be released during burst shooting.

–  Reactivating the standby timer would sometimes fail to re-establish the link between the camera and some makes of mobile router connected via Ethernet cable (Prioritize power saving  selected for  SETUP MENU  >  Network  >  Options  >  Power saving).

. The focal lengths displayed when teleconverters for AF-S or AF-I lenses are attached have been updated as follows:

The focal length displays for some combinations of lenses and teleconverters may differ from those given above.

. The  SETUP MENU  >  Time zone and date  >  Time zone  display now shows only the names of major cities in the currently selected zone.
