Nikon Releases Firmware Updates for D800 and D4
By Joseph Tepper, July 19, 2026 @ 09:44 AM (EST)

Today, Nikon announced several new firmware updates for their full-frame DSLRs. The update, v.1.01, for the D4 fixes several performance bugs, most noticeably a glitch that caused the camera to slow or lock up while recording still images during playback mode.

Version A v.1.01 for the D800 and B v.1.01 for the D800E fixes the same bug mentioned above, as well as the appearance of a dark shadow at the bottom edge of images captured in Active D-Lighting.

Both firmware upgrades and more information on improvements can be found on Nikon’s support site. Make sure to check out Keri Wilk's "pre-review" of the D800, found exclusively here on DPG.
