Nikon, like Canon, makes a lot of different lenses. As with the Canon lenses, I've only listed lenses here because I have either used them myself, or I know someone I trust who has used them specifically for astrophotography. The following lenses and astrophotographic performance descriptions apply to APS-sized 1.3x, 1.5x and 1.6x crop-factor sensors. In general, lens performance gets worse in the corners as the sensor size gets larger. These evaluations are subjective and not quantitative.
Prices and availability are subject to change without notice. The Nikon F Lens Mount Most older Nikon lenses made after 1971 will work on the new Nikon DSLR camera bodies, with a few exceptions. Check with Nikon before you buy an old lens to make sure it will work with your camera. Basically, any AI, or AIs lens should work with a Nikon DSLR body. However, you may not get the full functionality of the camera or lens. For example, you won't get autofocus with a manual-focus only lens. Be very careful with pre-AI lenses. They may damage the camera on some Nikon DSLR camera bodies. Nikon DX Lenses Like Canon, Nikon also has a series of lenses that are made specifically for smaller-sized sensors in consumer DSLR cameras. Nikon uses a DX designation for these type lenses. DX lenses usually have a rear element that protrudes more into the camera body and covers a smaller image circle. When these lenses are used on a larger sensor they will vignette and have poorer performance in the corners Nikon does not recommend their use on full-sized sensors like in the D3 or D700. Sigma Lenses for Nikon Sigma also makes lenses in the Nikon F mount. These lenses are less expensive, but some are quite good. Quality control seems to be a little bit more of a problem though, so individual samples of lenses can vary. Test them if you can before you buy them. Sigma makes some Nikon-mount lenses that are very good for astrophotography on a budget. In particular these specific lenses are recommended for astrophotography:
