The 400mm Lens Equivalent
Explanation of the 400mm Lens Equivalent
The 400mm lens equivalent is a term used to describe the focal length of a lens in terms of its effective field of view. It is a measure of the angle of view of a lens, which is the amount of the scene that can be captured in a single image. The 400mm lens equivalent is typically used to describe the field of view of a lens when it is used on a full-frame camera.
When a lens is used on a full-frame camera, the image that is captured is the same size as the sensor in the camera. This means that the angle of view of the lens is determined by the physical length of the lens, rather than the crop factor of the camera. The crop factor is the ratio of the sensor size to the size of a full-frame sensor. For example, a camera with a crop factor of 2 would have a sensor that is half the size of a full-frame sensor.
The 400mm lens equivalent is calculated by multiplying the physical length of the lens by the crop factor of the camera. For example, a lens with a physical length of 100mm that is used on a camera with a crop factor of 2 would have a 400mm lens equivalent. This means that the lens would have the same field of view as a lens with a physical length of 400mm when used on a full-frame camera.
It is important to note that the 400mm lens equivalent is only applicable when a lens is used on a camera with a crop factor. When a lens is used on a full-frame camera, the angle of view of the lens is determined by its physical length.
How to Determine the 400mm Lens Equivalent
Determining the 400mm lens equivalent can be a bit tricky, but with a few simple steps, you can easily calculate it. Here’s a step-by-step guide to help you determine the 400mm lens equivalent:
- Crop Factor: The first step in determining the 400mm lens equivalent is to determine the crop factor of your camera sensor. The crop factor is the ratio of the diagonal length of the sensor to the diagonal length of a full-frame sensor. For example, if you have a crop factor of 2, then the diagonal length of your sensor is half that of a full-frame sensor.
- Lens Focal Length: The next step is to determine the focal length of the lens you want to convert to the 400mm equivalent. For example, if you have a 100mm lens, you would multiply the focal length by the crop factor to get the 400mm equivalent.
- Sensor Size: The third step is to determine the size of your camera sensor. This information can usually be found in the camera’s manual or online. The sensor size will be expressed in inches or millimeters.
- Calculation: Finally, you can calculate the 400mm lens equivalent by multiplying the focal length by the crop factor and then dividing by the sensor size. For example, if you have a 100mm lens with a crop factor of 2 and a sensor size of 24mm x 16mm, the calculation would be:
100mm x 2 x (24mm / 25.4mm) x (16mm / 25.4mm) = 200mm
Therefore, the 400mm lens equivalent for a 100mm lens on a camera with a crop factor of 2 and a sensor size of 24mm x 16mm would be 200mm.
It’s important to note that the 400mm lens equivalent is not always an exact measurement, as it can vary depending on the specific camera and lens combination. However, using the steps outlined above can give you a good estimate of the equivalent focal length.

3. How does a 400mm lens compare to other lenses in terms of image quality?
The image quality of a 400mm lens can vary depending on the specific lens model and the conditions in which it is used. In general, a 400mm lens can produce high-quality images with good sharpness and contrast, especially when used for distant subjects. However, it may not perform as well in low light conditions or when shooting at high ISO settings. Other lenses, such as telephoto zoom lenses or mirrorless lenses, may offer similar or better image quality in certain situations.
4. What types of photography or videography are best suited for a 400mm lens?
A 400mm lens is well-suited for a variety of photography and videography genres, including wildlife, sports, and landscape photography. Its long focal length allows the user to capture distant subjects with great detail and clarity, making it ideal for capturing wildlife in their natural habitats or sports events from a distance. It can also be used for portrait photography, but its long focal length may make it difficult to get close to the subject.
5. Are there any downsides to using a 400mm lens?
One downside to using a 400mm lens is its size and weight. It is typically a large and heavy lens, making it difficult to carry around or use for extended periods of time. It may also be difficult to use for low-light photography or videography, as its long focal length can make it challenging to stabilize the camera. Additionally, its price point may be prohibitive for some photographers and videographers.
