Understanding the Nikon D100’s Autofocus System
The Nikon D100 boasts a sophisticated autofocus system with 5 focus points arranged in a cross pattern. This system offers a good balance between accuracy and coverage, making it suitable for a wide range of shooting scenarios.
Selecting the Right Focus Mode
The Nikon D100 offers three primary autofocus modes, each tailored to specific shooting situations:
- Single-servo AF (AF-S): Ideal for stationary subjects, this mode locks focus on the initial point and maintains it until you release the shutter button.
- Continuous-servo AF (AF-C): Designed for moving subjects, this mode continuously tracks the subject’s movement, adjusting focus as needed.
- Auto-area AF (AF-A): This mode automatically switches between AF-S and AF-C based on the camera’s assessment of the scene.
Choosing the Appropriate Focus Point
The Nikon D100’s 5 focus points offer flexibility and control over your composition.
- Center Focus Point: The most accurate, it’s ideal for precise focusing when the subject is directly in the center of the frame.
- Off-Center Focus Points: These points allow you to focus on subjects located off-center, expanding your compositional possibilities.
Utilizing the Focus Lock Button
The Nikon D100’s focus lock button, located on the back of the camera, is a powerful tool for fine-tuning your focus.

Navigating the Autofocus Settings
The Nikon D100’s autofocus settings provide additional control and customization:

- Utilize the Focus Assist Lamp: In low light situations, the focus assist lamp can illuminate your subject, aiding the autofocus system in finding focus.
