A new addition to my manual focus Nikkor collection: The Nikkor Ai 25-50 f4 zoom lens.

Zoom 25-50mm f4.

One of Nikon’s early professional zoom lenses, which should complement my ‘F’ camera quite nicely. This lens was manufactured in 1981 and by the end of that year was changed by Nikon to an Ai-s version. For some reason the second-hand price for the Ai-s version is more expensive than the Ai, there is no real reason for buying the later version unless one owns a Nikon FA camera, even then it is questionable as the internal construction of both lenses is exactly the same. All Ai / Ai-s lenses fit on every Nikon SLR camera, be they manual or AF with one caveat; some of the cheaper AF cameras will not meter with manual focus lenses (check your instruction manual). The only warning I would add here is ‘non Ai lenses’ made for the Nikon ‘F’ will damage most other cameras, with the exception of the F3, F4 & the Df !

This lens has some very nice qualities;  although long discontinued, it is without colour aberrations and images are sharp from corner-to-corner, light fall-off being very low even wide open. It will attain peak sharpness at f/5.6 and holds well even when stopped down to f/16 which delivers very good results.
Looking forward to cooler weather  😎 so that I can get out & about with it fitted on both film and digital cameras.

  1. I don’t remember that lens David. but after looking it up, I wonder why.
    I’ll bet it’s a great lens for walking around with.

      I think it was made only for a few years, but the build quality is typical of when Nikon made lenses that last forever !!! rather than some of the stuff they foist on us today.
