What Do AF-S And AF-P Stand For In Nikon Lenses?
AF-S and AF-P are designations used by Nikon to describe the type of autofocus motor used in their lenses. AF-S stands for Auto Focus with Silent Wave Motor, while AF-P stands for Auto Focus with Pulse Motor. The main difference between the two is the type of motor used to drive the autofocus system.
The Silent Wave Motor used in AF-S lenses is a more traditional type of motor that uses a series of waves to drive the autofocus system. This motor is generally quieter and more precise than the Pulse Motor used in AF-P lenses. However, the Pulse Motor is more compact and energy-efficient, making it ideal for use in smaller and lighter lenses.
What Is The Main Difference Between AF-S And AF-P Lenses?
The main difference between AF-S and AF-P lenses is the type of autofocus motor used. AF-S lenses use a Silent Wave Motor, while AF-P lenses use a Pulse Motor. The Silent Wave Motor is generally quieter and more precise, but it is also larger and more power-hungry. The Pulse Motor, on the other hand, is more compact and energy-efficient, but it can be noisier and less precise.
In terms of performance, AF-S lenses tend to be faster and more accurate when it comes to autofocus. However, AF-P lenses are still capable of delivering fast and accurate autofocus, especially in good lighting conditions. The choice between AF-S and AF-P ultimately comes down to personal preference and the specific needs of the photographer.
Are AF-P Lenses Compatible With All Nikon Cameras?
AF-P lenses are compatible with most Nikon cameras, but there are some exceptions. Older Nikon cameras, such as those from the D3000 and D5000 series, may not be compatible with AF-P lenses.
