WebDepth-of-Field. When observing an object with a lens, the object is most clearly viewed when it is at the focal point of the lens. If the distance between the lens and the object is slightly varied, then there is a range or tolerance in which the object can still be clearly observed. This range is known as the depth-of-field (DoF). steve forbes inflation bookWebDepth of field tells you the range of distances from sensor/film where your subject can move in scene so it would still remain in focus.

WebAt high numerical apertures of the microscope, depth of field is determined primarily by wave optics, while at lower numerical apertures, the geometrical optical circle of confusion dominates the phenomenon. pissedconsumer fordWebDepth of Focus. The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus. pissed consumer meaningWebIn this case, f-stop = 50mm/25mm = 2 (f/2). If the focal length is 400mm and the aperture opening is 50 mm, then we can easily count the f-stop number. f-stop = 400mm/50mm = 8 (f/8).
