Understanding Manual Focus
Manual focus is a technique that allows you to control the camera’s lens manually, adjusting the focus distance to ensure that your subject is sharp. Unlike autofocus, which relies on sensors to determine the focus point, manual focus gives you complete creative control.
Benefits of Manual Focus
- Precision: Manual focus provides unparalleled precision, allowing you to focus on specific areas of your subject with pinpoint accuracy.
- Creative Control: By manually focusing, you have the freedom to experiment with different compositions and create unique perspectives.
- Shallow Depth of Field: Manual focus enables you to achieve shallow depth of field effects, isolating your subject and creating a beautiful blurred background.
How to Manually Focus Your Nikon D90
1. Set the Focus Mode Switch to “M”
Locate the focus mode switch on the lens barrel and set it to “M” for manual focus.
2. Enable Live View
Press the “Live View” button on the back of the camera to activate Live View mode. This will display a live preview of the scene on the LCD screen.
3. Zoom In on Your Subject
Use the zoom controls to magnify your subject on the LCD screen. This will help you focus more precisely.
4. Adjust the Focus Ring
Gently rotate the focus ring on the lens until the subject appears sharp. You may need to switch between zooming in and out to achieve the desired focus.
5. Confirm Focus
Once you are satisfied with the focus, press the shutter button halfway to lock the focus. The focus indicator in the viewfinder or on the LCD screen will turn green to confirm.
Advanced Manual Focus Techniques
1. Focus Peaking
Enable focus peaking in the camera’s menu. This will highlight the sharpest areas of the image in color, making it easier to achieve accurate focus.
2. Focus Magnification
Press the “Magnify” button on the back of the camera to enlarge a specific area of the image. This can be useful for fine-tuning the focus on small details.
3. Hyperfocal Distance
Hyperfocal distance is the point beyond which everything in the scene will be in focus. Calculating and using hyperfocal distance can help you achieve maximum depth of field.
Tips for Manual Focus
- Use a tripod for stability, especially when shooting at slow shutter speeds.
- Practice regularly to develop your manual focus skills.
- Use a focus chart to calibrate your lens and ensure accurate focus.
- Experiment with different focus points to create dynamic compositions.
- Don’t be afraid to make mistakes. Manual focus is an art form that takes time and patience to master.

- Autofocus-Single (AF-S): Focuses on a single point and locks the focus when the shutter button is half-pressed.
- Autofocus-Continuous (AF-C): Continuously adjusts the focus as the subject moves.
- Autofocus-Area (AF-A): Automatically selects the focus point based on the scene.
