When it comes to choosing a camera, photographers often find themselves torn between Nikon’s FX and DX formats. Both formats have their loyal followings, and each has its unique strengths and weaknesses. But which one reigns supreme? In this article, we’ll delve into the world of FX and DX, exploring their differences, similarities, and ultimately, which one is better suited for your photography needs.
Understanding the Basics: FX and DX Explained
Before we dive into the nitty-gritty, it’s essential to understand what FX and DX are. FX, also known as full-frame, refers to a camera’s sensor that is equivalent in size to a 35mm film frame (36mm x 24mm). This means that the sensor can capture the entire image projected by the lens, resulting in a more comprehensive and detailed image.
On the other hand, DX, also known as APS-C (Advanced Photo System type-C), is a cropped sensor format that measures approximately 24mm x 16mm. This smaller sensor size results in a crop factor, which affects the camera’s field of view and depth of field.
Key Differences: FX vs DX
Now that we’ve covered the basics, let’s explore the key differences between FX and DX:
Sensor Size and Crop Factor
FX sensors are larger, which results in a few significant advantages:
- Better low-light performance: FX sensors can capture more light, leading to cleaner images with less noise in low-light conditions.
- Shallow depth of field: The larger sensor allows for a shallower depth of field, making it easier to isolate subjects and create a more cinematic look.
- Wider dynamic range: FX sensors can capture a broader range of tonal values, resulting in more detailed shadows and highlights.
DX sensors, on the other hand, have a crop factor of approximately 1.5x. This means that the camera’s field of view is reduced, making it ideal for:
- Telephoto applications: The crop factor can be advantageous for wildlife, sports, and portrait photographers who want to get closer to their subjects without sacrificing image quality.
- Increased reach: DX cameras can make the most of telephoto lenses, effectively turning a 200mm lens into a 300mm lens.
Lens Compatibility and Mounts
FX cameras can use both FX and DX lenses, but DX cameras can only use DX lenses or FX lenses with a crop factor applied. This means that DX cameras will always have a crop factor, even with FX lenses.

Whether you’re a seasoned pro or just starting out, understanding the differences between FX and DX will help you make an informed decision when choosing your next camera. So, which one is better? The answer is simple: it depends on you.
What is the difference between FX and DX sensors?
The primary difference between FX and DX sensors is the size of the sensor. FX sensors are full-frame sensors, which are equivalent in size to a 35mm film frame, measuring 36mm x 24mm. DX sensors, on the other hand, are smaller, measuring 24mm x 16mm, and are also known as crop sensors.
This size difference affects the camera’s field of view, depth of field, and low-light performance. FX sensors have a wider field of view and shallower depth of field, making them ideal for portraiture, landscape, and architecture photography. DX sensors, with their smaller size, have a narrower field of view and deeper depth of field, making them suitable for sports, wildlife, and action photography.
Can I use FX lenses on a DX camera?
Yes, you can use FX lenses on a DX camera. DX cameras are designed to work with both DX and FX lenses. When using an FX lens on a DX camera, the camera will automatically crop the image to fit the DX sensor’s smaller size. This means that you’ll only be using the center portion of the lens’s image circle, which can sometimes result in a slight loss of image quality.
However, FX lenses are designed to work with full-frame sensors, so you may not be taking full advantage of the lens’s capabilities. DX lenses, on the other hand, are specifically designed for DX sensors and are optimized for their smaller size. Using a DX lens on a DX camera will provide the best possible image quality and performance.
Can I use DX lenses on an FX camera?
While it’s technically possible to use a DX lens on an FX camera, it’s not recommended. DX lenses are designed to work with DX sensors, and when used on an FX camera, they will not cover the entire sensor area. This can result in vignetting, where the edges of the image are darkened or distorted.
FX cameras have the ability to automatically detect when a DX lens is attached and will crop the image to fit the DX sensor’s size. However, this can result in a lower megapixel count, and you may not be taking full advantage of the FX camera’s capabilities. For the best results, it’s recommended to use FX lenses on FX cameras and DX lenses on DX cameras.
Will I experience a crop factor when using an FX lens on a DX camera?
Yes, when using an FX lens on a DX camera, you will experience a crop factor. The crop factor is approximately 1.5x, which means that the camera will crop the image to fit the DX sensor’s smaller size. This means that a 50mm FX lens will have an effective focal length of 75mm on a DX camera.
The crop factor can be beneficial in certain situations, such as sports or wildlife photography, where a longer focal length can be advantageous. However, it can also limit your creative options, especially in situations where a wider angle of view is needed. It’s essential to consider the crop factor when choosing a lens and camera combination to ensure you’re getting the desired results.
Do FX cameras have better low-light performance than DX cameras?
Generally, FX cameras have better low-light performance than DX cameras. This is due to the larger sensor size, which allows for larger pixels that can capture more light. This results in better noise performance, more accurate colors, and a shallower depth of field in low-light conditions.
However, modern DX cameras have made significant advancements in low-light performance, and some high-end DX models can rival the performance of older FX cameras. Additionally, the latest FX cameras have also improved low-light performance, making them even more capable in challenging lighting conditions.
Are FX cameras more expensive than DX cameras?
