The Nikon D700 is a powerful DSLR that offers a wide range of creative control, and understanding how to change the f-stop is crucial for achieving the desired depth of field in your photos. This comprehensive guide will walk you through the process of adjusting the f-stop on your Nikon D700, explaining the different modes and techniques for achieving the perfect balance between sharpness and blur.
Understanding Aperture and F-Stop
Before diving into the practical steps, let’s briefly define what aperture and f-stop represent. Aperture refers to the opening within the lens that controls the amount of light reaching the camera sensor. The f-stop, expressed as a number like f/2.8 or f/16, represents the size of this opening. A lower f-stop number (e.g., f/2.8) indicates a wider aperture, allowing more light to pass through and resulting in a shallower depth of field (more blur in the background). Conversely, a higher f-stop number (e.g., f/16) indicates a smaller aperture, allowing less light to pass through and creating a deeper depth of field (more focus throughout the image).
Choosing the Right Shooting Mode
The Nikon D700 offers various shooting modes that allow you to control the aperture, including:
- Aperture-Priority Mode (A): This mode gives you control over the aperture while the camera automatically adjusts the shutter speed to achieve proper exposure. This is ideal for photographers who want to prioritize depth of field while letting the camera handle the exposure settings.
- Manual Mode (M): In manual mode, you have complete control over both aperture and shutter speed. This is the most advanced mode, allowing for precise control over all aspects of exposure.
- Program Mode (P): This mode allows the camera to automatically select both aperture and shutter speed, but you can adjust the aperture within a limited range. This mode is a good starting point for beginners who want to explore aperture control without diving into manual settings.
Using the Aperture Ring (If Applicable)
Some Nikon D700 lenses, particularly older models, feature an aperture ring that allows you to directly adjust the f-stop. To change the f-stop using the aperture ring:
1. Locate the aperture ring: This ring is typically found on the lens barrel, usually near the front of the lens.
2. Rotate the ring: Turn the ring clockwise to increase the f-stop (smaller aperture) and counterclockwise to decrease the f-stop (wider aperture).
3. Confirm the setting: The selected f-stop value will be displayed in the viewfinder or on the camera’s LCD screen.
Adjusting Aperture in Shooting Modes
If your lens doesn‘t have an aperture ring, you can adjust the aperture using the camera’s controls:
1. Select the desired shooting mode: Choose either Aperture-Priority (A) or Manual (M) mode, depending on your desired level of control.
2. Use the command dial: Rotate the command dial on the back of the camera to change the f-stop value. The selected f-stop will be displayed in the viewfinder or on the camera’s LCD screen.
3. Check the exposure: After adjusting the aperture, monitor the exposure indicator in the viewfinder or on the LCD screen to ensure proper exposure. You may need to adjust the shutter speed accordingly.
Tips for Choosing the Right F-Stop
The choice of f-stop depends on the desired effect, the subject matter, and the lighting conditions:
- Shallow Depth of Field (Low F-Stop): Use a wide aperture (low f-stop) to isolate the subject from the background, creating a blurred background effect. This is ideal for portraits, macro photography, and low-light situations where you need to maximize light entering the lens.
- Deep Depth of Field (High F-Stop): Use a smaller aperture (high f-stop) to keep the entire scene in focus, from foreground to background. This is useful for landscapes, architecture, and group photos where you want to ensure all elements are sharp.
Understanding the Effects of Aperture
Changing the f-stop affects more than just the depth of field:
- Light: A wider aperture allows more light to pass through the lens, making it easier to shoot in low-light conditions.
- Shutter Speed: When you adjust the aperture, you may need to adjust the shutter speed to maintain proper exposure. A wider aperture allows faster shutter speeds, while a smaller aperture requires slower shutter speeds.
- Diffraction: At very small apertures (high f-stop), diffraction can occur, which can cause a slight softening of the image.
Mastering Aperture for Creative Photography
By understanding the relationship between aperture and f-stop, you can unlock a world of creative possibilities with your Nikon D700. Experiment with different f-stop values to see how they affect the depth of field, light, and overall image quality.
Beyond the Basics: Advanced Techniques
For more advanced photographers, there are additional techniques to consider when using aperture:
- Aperture Bracketing: This technique involves taking multiple shots of the same scene at different apertures, allowing you to choose the best depth of field later in post-processing.
- Focus Stacking: This technique involves taking multiple shots of the same scene at different focus points, then combining them in post-processing to achieve a greater depth of field than possible with a single shot.

Remember, the best f-stop setting is the one that achieves your desired creative vision. Experiment, explore, and find the f-stops that help you capture the world in your unique way.
Quick Answers to Your FAQs
1. What is the difference between aperture and f-stop?
Aperture refers to the opening within the lens, while f-stop is a numerical representation of the size of that opening. A lower f-stop number indicates a wider aperture, and a higher f-stop number indicates a smaller aperture.
2. Why is it important to change the f-stop?
Changing the f-stop allows you to control the depth of field, which affects how much of the scene is in focus. It also influences the amount of light entering the lens, affecting exposure and shutter speed.
3. How do I know which f-stop to use?
The best f-stop depends on your creative vision and the specific shooting situation. Consider the desired depth of field, the amount of light available, and the subject matter.
4. Can I change the f-stop on all lenses?
Not all lenses have an aperture ring. Some lenses require you to adjust the aperture through the camera’s controls.
5. What is diffraction, and how does it affect my photos?
Diffraction occurs at very small apertures (high f-stop), causing a slight softening of the image due to light waves bending around the edges of the lens opening.
