Description
The later 1978 AI version of the first wide-angle zoom by Nikon and in fact the first wide angle zoom ever that started at a focal length of 28mm. In it’s time the 28-45 was a real sensation and a technological breakthrough. It was aimed at the professional market and was produced between 1975 and 1978 with a total production of about 20.000 lenses.
This lens is sharp enough even wide open on low-res sensors. Overall image quality is good and performs well on the long or wide end. CA is a non-issue.
You may find it best to stop down to f/8; however, image quality is still good stopped down below f/5,6 compared to modern kit zooms.
