Nikon has today posted firmware version 1.7 for the 8 megapixel Coolpix 8800 and version 1.5 for the Coolpix 8400. The firmware addresses a number of issues; the shutter releases immediately when using the self-timer and remote control together and the self-timer can now be used with certain scene modes including fireworks, museum and sports. Both cameras can now use 6GB Microdrives. Problems caused by selecting Quick response for the Release speed option have also been rectified.
