Nikon has announced a new firmware update for its high-end D4s DSLR that gives it a number of new abilities and fixes, among which are unlimited continuous shooting and unlimited exposure time.
There’s no longer a limit to how many shots you can take in one burst when you’re shooting in Shutter priority or Manual modes. There’s also no limit now on how long you can keep your shutter open when you’re using Time for shutter speed — photographers were previously capped at 30 minutes for a single exposure.
Other improvements — besides a number of bug fixes — include: new support for the Nikon SB-500 flash, more consistent auto white balance, and a change in how focus points are shown in your viewfinder if you rotate your camera between portrait and landscape modes.
You can find all the changes, read about them in more detail, and download the new firmware over in the Nikon Download center.
