Nikon NIKKOR AF-S NIKKOR 24mm f/1.4G ED 24mm
78 out of 100 high confidence 74 reviews
The Nikon 24mm f/1.4G ED is widely praised for its exceptional sharpness, beautiful bokeh, and outstanding low-light performance, making it a favorite among professionals. However, a significant number of users report autofocus issues, particularly at distances beyond 30 feet or at wide apertures, which can be inconsistent across copies. Despite its high price, most agree it delivers superb image quality, though some note it is slightly soft wide open and heavy.
