The website is a guide to astrophotography created for photo hobbyists interested in shooting astronomical bodies, as well as for those new to astrophotography. In addition to recommending specific Nikon cameras and NIKKOR lenses, the guide also introduces the peripheral equipment needed for successful astrophotography, including tripods, optical telescopes, and equatorial telescopes. Optimal shooting techniques, such as fixed-mount photography and tracked-mount photography and required accessories for each category of Nikon camera—digital SLRs, Nikon 1, and COOLPIX compact digital cameras are explained in detail.
Nikon has released firmware updates for both the D5200 and D7100 cameras. Both new versions of the firmware reduce horizontal line noise in videos recorded at 1280×720/60p and 1280×720/50p. In addition, firmware v. 1.03 fixes an issue that causes the cameras to freeze when the ‘clean image sensor’ option is selected.
Nikon has issued another service advisory for users of the Nikon D750.
“It has come to our attention that the shutter in some Nikon D750 digital SLR cameras manufactured in October and November of 2014 does not function normally, sometimes resulting in shading of a portion of images. We have decided to take the following measures regarding this issue.
We sincerely apologize for any inconvenience this issue may have caused.
