The field of view of an 18mm lens is the width of the scene that can be captured in a photograph. It is typically around 76 degrees.
An 18mm lens has a wider angle of view compared to a 55mm lens, making it better for capturing landscapes and wide scenes. On the other hand, a 55mm lens has a narrower angle of view, making it more suitable for portraits and close-up shots with a shallower depth of field.
The term "lens mm" in photography refers to the focal length of a camera lens, measured in millimeters. A higher focal length (e.g. 50mm, 100mm) means a narrower field of view and more magnification, while a lower focal length (e.g. 18mm, 24mm) means a wider field of view. The focal length impacts the perspective, depth of field, and compression of the image, which in turn affects the quality and composition of the photo.
The key differences between a 10mm and a 22mm Canon lens are the focal length and field of view. The 10mm lens has a wider field of view, capturing more in the frame, while the 22mm lens has a narrower field of view, ideal for capturing subjects from a distance. Additionally, the 10mm lens may have a shallower depth of field compared to the 22mm lens, resulting in different levels of background blur in photos.
A telephoto lens has a fixed focal length and provides a narrow field of view for capturing distant subjects, while a zoom lens has a variable focal length that allows for adjusting the magnification and field of view.
Different mm lenses have varying focal lengths, which affect the field of view and magnification of the photographs taken. A lower mm lens, such as 18mm, captures a wider scene, while a higher mm lens, like 200mm, zooms in on distant subjects. The choice of lens impacts the composition, depth of field, and overall quality of the photographs by influencing perspective, sharpness, and background blur.

The main difference between an 18mm, 20mm, and 22mm loupe is the size of the lens. The larger the lens diameter, the more light it can let in and the larger the field of view. A larger loupe may provide a clearer and broader magnified view compared to a smaller one.
This describes the focal length range of the lens. It means that the lens can be set between 18mm (a wide angle which takes in a larger field of view) and 200mm (a telephoto, which creates a narrower field of view). ******* Note: the above is certainly true for 35mm format, but focal length is relative to the format. For 4x5 cameras, the equivalent "normal" focal length is around 200mm.
There is a relationship between the power of an objective lens and its field of view. As the power of the objective lens increases, the size of its field of view decreases
The field of view of the oil immersion 100x lens would be 0.4 mm. This is because the field of view decreases as the magnification increases.
The field of view becomes narrower.

The field of view (FOV) of a microscope refers to the area visible through the lens. It is determined by the diameter of the microscope's field diaphragm and the objective lens magnification. A higher magnification will typically result in a smaller field of view, while lower magnifications will have a larger field of view.
The lowest magnification objective lens, such as the 4x lens, typically provides the largest field of view because it allows more of the specimen to be visible at once. This is useful for observing larger structures or getting an overall view of a specimen before zooming in with higher magnification lenses.
