WebA stadia measurement was undertaken with a theodolite having an internal focusing telescope and a stadia inter- val factor of 98.8. When a backsight was taken on a turning point whose elevation is 205.62m, the rod interval observed was 1.94m; and with the horizontal hairs set at 1.50m on the rod, the vertical angle reading was -13045'. WebQuestion: QUESTION 4 Problem 4 (15%) A dumpy level with an internal focusing telescope is set up on one end of a line to be measured by the stadia method. The upper and lower stadia hair readings on a rod held at the other end of the line were recorded as 1.404 and 1.202 m. respectively. The stadia interval factor of the instrument used is 98.

WebQuestion: In determining the stadia interval factor K of an internal-focusing telescope, a stadia rod was held vertically at several points along measured distances from the instrument and the corresponding stadia hair readings were observed. WebFor non-zoom lenses, internal focusing probably means that the bellows effect (in which air is sucked into the lens) is minimised since the outside of the lens probably won't move during focusing. That means the interior of your camera doesn't get humid or dusty (and so less crud adheres to the sensor).
