What To Know
- This comprehensive guide will delve into the various focus modes, settings, and techniques available on the D750, empowering you to achieve precise focus in any shooting situation.
- Half-press the shutter button to lock focus on a subject, recompose the frame, and then press the shutter button fully to capture the image.
- A wider aperture (lower f-number) will create a shallower depth of field, isolating the subject from the background, while a narrower aperture (higher f-number) will result in a greater depth of field, keeping more of the scene in focus.
The Nikon D750 is a versatile full-frame DSLR camera known for its exceptional image quality and focusing capabilities. Understanding how to focus your D750 accurately is crucial for capturing sharp and stunning photographs. This comprehensive guide will delve into the various focus modes, settings, and techniques available on the D750, empowering you to achieve precise focus in any shooting situation.
Focus Modes
The D750 offers three primary focus modes:
- Single-Servo AF (AF-S): Suitable for stationary subjects or when you want to lock focus on a specific point.
- Continuous-Servo AF (AF-C): Ideal for tracking moving subjects, such as sports or wildlife.
- Manual Focus (MF): Provides full control over focus, allowing you to manually adjust the lens’s focus ring.
Autofocus Settings
Once you have selected the appropriate focus mode, you can further refine your focus settings:
- Focus Area Mode: Choose from various focus area patterns, including single-point, dynamic-area, and group-area AF.
- AF-C Custom Settings: Adjust the tracking sensitivity, acceleration/deceleration, and focus point switch threshold for AF-C mode.
- AF Fine-Tune: Calibrate the focus accuracy of specific lenses to compensate for any potential front- or back-focusing issues.
Focus Techniques
- Focus Point Selection: Use the multi-selector or touchscreen to precisely position the focus point on the subject.
- Focus Lock: Half-press the shutter button to lock focus on a subject, recompose the frame, and then press the shutter button fully to capture the image.
- Focus Peaking: Enable focus peaking in the camera’s settings to highlight in-focus areas with a colored outline.
Aperture and Focus
The aperture setting affects the depth of field, which influences the amount of subject matter that will be in focus. A wider aperture (lower f-number) will create a shallower depth of field, isolating the subject from the background, while a narrower aperture (higher f-number) will result in a greater depth of field, keeping more of the scene in focus.
Lens Choice and Focus
The lens you choose will also impact your focusing capabilities. Lenses with wider maximum apertures (e.g., f/2.8 or wider) allow for more precise focus and shallower depth of field control. Prime lenses, which have a fixed focal length, typically offer better focusing performance compared to zoom lenses.
Troubleshooting Focus Issues
- Front- or Back-Focusing: If your images are consistently out of focus, use the AF fine-tune setting to calibrate the focus accuracy of the lens.
- Slow Focus: Ensure that the focus mode is set to AF-S for stationary subjects and AF-C for moving subjects. Check the lens’s autofocus motor for any potential issues.
- Erratic Focus: Disable focus peaking or other focus aids that may interfere with the camera’s autofocus system. Clean the lens contacts and ensure that the lens is securely mounted to the camera body.
Final Note: Mastering Nikon D750 Focus
By understanding and applying the focus modes, settings, and techniques outlined in this guide, you can master the art of focusing your Nikon D750. Whether you’re capturing portraits, landscapes, or action shots, the ability to achieve precise focus will elevate your photography to new heights.

Common Questions and Answers
Q: How do I choose the best focus area mode for my subject?
A: For stationary subjects, use single-point AF. For moving subjects, use dynamic-area or group-area AF.
Q: What is the difference between AF-S and AF-C modes?
A: AF-S locks focus on a single point, while AF-C continuously tracks moving subjects.
Q: How do I calibrate the focus of my lens?
A: Use the AF fine-tune setting in the camera’s menu to adjust the focus accuracy for specific lenses.
Q: What is focus peaking and how do I use it?
A: Focus peaking highlights in-focus areas with a colored outline. Enable it in the camera’s settings and adjust the sensitivity to suit your needs.
Q: Why is my camera focusing slowly?
A: Ensure that the focus mode is set to AF-S for stationary subjects. Check the lens’s autofocus motor for any issues or consider using a lens with a faster maximum aperture.
