(Some Nikkors won't work such as 'G' series) but this might -- I found one of these lenses at a "Car Boot sale" for 5 GBP ( about 9 USD) so it seemed to me to be worth a try.
Don't mind if I have to use it in stopped down or purely MF mode although often in "Stoped down mode" you can still get Aperture Priority to work.
Canon is a bit lacking in the wide angle primes.
The Nikon 20mm f2.8 is a good (but not great) lens. However, it is an order of magnitude sharper than any of the serveral Canon EF 20mm f2.8 lenses I've owned.
If you're looking to get one for use on a Canon body, I would recommend the manual focus version. Same optical design as the current AF version, but nicer handling and focusing.
