Update Jan 16 8 PM: Nikon silently updated the updater. The folder on the updater disk image was named “Nikon D810”. Doesn’t inspire confidence. Presumably “D850_0101.bin” is unchanged.
Also, I successfully updated the D850 firmware and its lens correction data (separate download).
Back in October I wrote about serious damage to image quality on the Nikon D850 with Long Exposure Noise Reduction (LENR) enabled.
I am not aware that the major testing sites found this issue, or included it in their ratings (this is is a friendly poke at a few readers that have insisted on validity of “scientific” testing of sites like DxO which sometimes miss the forest for the trees).
Nikon has now published a firmware update that claims to fix the issue.
Changes from “C” Firmware Version 1.00 to 1.01
Fixed the following issues:
- Users exiting Clean image sensor after adding it to and entering via MY MENU would be returned not to MY MENU but to the SETUP MENU.
- Photos taken with On selected for Long exposure NR would sometimes have increased noise or shadows with a greenish cast.
- Slight aperture reset lag would sometimes occur after shooting at shutter speeds under 1/10 s (type E and PC-E lenses excluded).
I am hesitant to link to the Nikon firmware updater page because the Nikon firmware updater page is insecure—use at your own risk. But here it is:
