Two manual focus zoom lenses made by Nikon are up for sale as used items. One is the Ai Zoom Nikkor 25-50mm F4, and the other is the Ai Zoom Nikkor 35-70mm F3.5. Both are compatible with the "rabbit ears" and Ai metering systems. Both lenses are designed so that the overall length does not change when zooming, as the lenses move within the lens barrel, which is said to make them less susceptible to dust entering. The lenses themselves have no operational issues other than a slightly light focusing ring. There is some dust inside, but no clouding or mold is visible. Both have been used for actual photography, and there were no issues with the image quality. Regarding the exterior, there are scratches, but no significant damage. The front part, which is easily damaged by drops, is not distorted, and filters can be attached. While not in pristine condition, I hope you will find them useful as practical items with no operational problems. The lenses will be shipped with two screw-on caps and rear caps.
