Nikon has released firmware version 1.30 for its D5 professional DSLR, and the new camera software offers a new feature that's potentially very useful: recall shooting functions.

The "recall shooting functions" option is now available for Custom settings f1 (custom control assignment) and can be configured so that pressing and holding specific controls will recall previously saved exposure settings (including shutter speed and aperture). The function is designed to allow for quick changes of shooting parameters in variable light conditions.

The function can be assigned to the Preview button, Fn1 button, Fn2 button, AF-ON button, Sub-selector center, AF-ON button for vertical shooting, or Lens focus function buttons. If you are using a WR-1 or WR-T10 remote control, it can also be assigned to the Fn buttons on those controls. An addendum to the camera manual that explains the new function in more detail can be downloaded on the Nikon website.

All other changes in this update are fairly minor. The focal lengths of some AF-S and AF-I lenses that are displayed with a teleconverter attached to the camera have been updated, and the time zone display in the Setup Menu only shows the names of major cities in the currently selected time zone. There are also a couple of minor bug fixes.

To read the full change log or download the new firmware for yourself, head over to the Nikon website.
