What To Know
- Focusing on the correct point ensures that the intended subject is in sharp focus, while the rest of the image may have a pleasing degree of blur.
- You can use selective focus to create a sense of depth, draw the viewer’s eye to a specific area, or highlight a particular element in your composition.
- The D750 allows you to customize the focus point selection settings, including the number of focus points used, the priority given to the center point, and the sensitivity of the autofocus system.
The Nikon D750 is a versatile and powerful camera, renowned for its exceptional image quality and advanced features. However, to truly harness its potential, it’s crucial to understand how to manipulate its autofocus system. This guide will walk you through the process of how to change the focus point on Nikon D750, empowering you to capture sharp and precise images in various scenarios.
Understanding the Autofocus System
The Nikon D750 boasts a 51-point autofocus (AF) system, offering a wide array of focus points to choose from. These points are arranged in a diamond pattern across the sensor, covering a broad area of the frame. This system allows you to select the specific focus point that best suits your composition and subject.
The Importance of Focus Point Selection
Choosing the right focus point is essential for achieving sharp images. Here’s why:
- Subject Isolation: By focusing on a specific part of your subject, you can isolate it from the background, enhancing its prominence in the frame.
- Sharpness and Clarity: Focusing on the correct point ensures that the intended subject is in sharp focus, while the rest of the image may have a pleasing degree of blur.
- Creative Control: You can use selective focus to create a sense of depth, draw the viewer’s eye to a specific area, or highlight a particular element in your composition.
Methods to Change Focus Points
The Nikon D750 offers several methods to change focus points, catering to different shooting styles and preferences:
1. Using the Multi-Selector
The most common and intuitive method involves the multi-selector, a small joystick located on the back of the camera, just below the thumb rest.
- Press and Hold: Press and hold the multi-selector button.
- Move the Joystick: While holding the button, move the joystick in the direction you want to shift the focus point. The selected focus point will be highlighted in the viewfinder.
- Release the Button: Release the button to confirm the new focus point.
2. The AF-Area Mode Selector
The AF-area mode selector, located on the top of the camera, allows you to adjust the autofocus area mode. This setting determines how the camera selects focus points automatically.
- Single-point AF: This mode allows you to select a single focus point manually, offering precise control over the focus area.
- Dynamic-area AF: This mode automatically selects the optimal focus point within a pre-defined area.
- 3D-tracking AF: This mode tracks a moving subject across the frame, maintaining focus even as it moves.
3. The Focus Point Selection Button
The focus point selection button, located on the back of the camera, provides an alternative method for selecting focus points.
- Press the Button: Press the button to cycle through the available focus points.
- Confirm: Press the shutter release button halfway to confirm the selected focus point.
Tips for Choosing the Right Focus Point
- Composition: Consider the composition of your image and the subject’s placement within the frame. Choose a focus point that aligns with your intended focal point.
- Subject Movement: For moving subjects, utilize dynamic-area AF or 3D-tracking AF to ensure accurate focus.
- Depth of Field: Understand the relationship between aperture, focal length, and depth of field. Adjust your settings accordingly to achieve the desired level of sharpness and blur.
- Experiment: Practice changing focus points in various shooting scenarios to develop a feel for the different methods and their effectiveness.
Beyond the Basics: Advanced Focus Point Techniques
For experienced photographers, the Nikon D750 offers additional tools for fine-tuning focus point selection:
1. Group-area AF
This mode allows you to select a group of focus points, providing a larger area of focus. It’s particularly useful for subjects that are partially obscured or for situations where precise focus is less critical.
2. Custom AF Point Selection
The D750 allows you to customize the focus point selection settings, including the number of focus points used, the priority given to the center point, and the sensitivity of the autofocus system.
Troubleshooting Focus Point Issues
If you’re experiencing difficulties with focus point selection, consider these troubleshooting steps:
- Clean the Lens: Dust or smudges on the lens can interfere with autofocus.
- Check the AF-area Mode: Ensure that the AF-area mode is set to the appropriate setting for the subject and shooting conditions.
- Adjust Focus Area: Try adjusting the focus area to encompass the subject more effectively.
- Use Manual Focus: If all else fails, switch to manual focus mode to take control of the focus point.
Mastering Focus: A Photographic Advantage
By understanding how to change the focus point on Nikon D750, you unlock a key element of photographic control. Experiment with different methods and settings to find what works best for your style and subjects. With practice and a keen eye for composition, you’ll be able to capture sharp, precise images that showcase your artistic vision.
Moving Forward: Sharpening Your Skills
Now that you’ve grasped the basics of focus point selection, it’s time to explore further. Focus on refining your technique, experimenting with different shooting scenarios, and understanding the nuances of autofocus in various lighting conditions. The Nikon D750 is a powerful tool, and mastering its focus system is a crucial step towards achieving your photographic goals.
Answers to Your Questions
1. What are the benefits of using a single focus point compared to dynamic-area AF?
Using a single focus point offers greater precision and control, allowing you to focus on a specific area of your subject. Dynamic-area AF, on the other hand, is more versatile and suitable for moving subjects or situations where precise focus is less critical.
2. How can I improve my focus accuracy when shooting in low light?
Low light conditions can make autofocus challenging. Consider using a faster lens (with a lower f-number), increasing the ISO sensitivity, or using a tripod to stabilize the camera. Additionally, check the camera’s autofocus settings, such as the AF-area mode and focus point selection.
3. Is it possible to change the focus point while shooting in live view mode?
Yes, you can change the focus point in live view mode using the touch screen. Simply tap on the desired focus area on the screen to select the focus point.
4. What is the difference between AF-S and AF-C modes?
AF-S (single-servo autofocus) is designed for stationary subjects, while AF-C (continuous-servo autofocus) is suited for moving subjects. AF-S locks focus on the initial point, while AF-C continuously tracks the subject as it moves.
5. Can I customize the focus point selection settings on the Nikon D750?
Yes, the D750 allows you to customize the focus point selection settings, including the number of focus points used, the priority given to the center point, and the sensitivity of the autofocus system. These settings can be accessed through the camera’s menu system.
