Field of view

Alvandi Camera Systems produce various types of 4x5, 5x7 and 8x10 inch large format and 679 medium format tilt-shift technical cameras, as well as a 6x17 panorama. In addition to the above, we produce according to the customer's request, all the photographic equipment accessories, for all types of large format, medium format, panoramic cameras, roll film back, etc for all regions of the world.

1. The field angle is inversely proportional to the lens focal length. Generally, the larger the lens focal length is, the smaller the field angle is.

The ALVANDI new viewfinder is redesigned. It has a 120° angle of view, with spirit level, that can be seen from the viewfinder. You can change a variety of masks based on lens and format. It has the ability to adjust the diopter.

The area covered by the visible image formed by the subject through the lens on the focal plane is the field of view of the lens, which is represented by the angle between the two sides of the display and the eye line.

As the golden eye of the whole monitoring system, the camera is responsible for keeping an eye on all the details of the monitoring occasions. Its "vision" is very important. Now, Xiaojin will briefly introduce some tips about the camera's field of view angle:

The larger the field angle is, the larger the field of view is, and the smaller the optical magnification is. Generally speaking, if the target object exceeds this angle, it will not be collected in the lens. The field angle is divided into horizontal field angle, vertical field angle and diagonal field angle.

Field of view (FOV for short) refers to the range that can be covered by the lens (objects beyond this angle will not be collected in the lens). The range that a camera lens can cover is usually expressed in terms of angle, which is called the FOV of the lens. Generally speaking, the angle formed by the limit of the range you can see by rotating your eyes while keeping your head still in front of the screen is called the field angle.

● Wide angle lens: the viewing angle is more than 90 degrees, the observation range is large, and the near image is deformed.

2. The field angle is proportional to the effective imaging size of the sensor. The higher the effective imaging height of the sensor, the larger the vertical field angle, the wider the effective imaging width of the sensor, and the larger the horizontal field angle.
