In sports photography, one often needs a long telephoto lens with a large aperture. As adesigner, you will work with engineers to design some new lens.“(i) Suppose you want to have an 500mm lens with aperture f/4. Calculate the requirediris diameter. Round your answer to the nearest integer and state its unit. “|(ii) Suppose you want to have a 700mm lens with a surface area of 12271.8463mm².Calculate the f-number. Correct your answer to 2_decimal places.

Please help me with the following question, explain and make sure it's correct, thank you sm!!
Photographs at a scale of S are required to cover an area X - mi square. The camera has a focal length and focal plane dimensions of 9 * 9in . If endlap is 60% and sidelap 30\% how many photos will be required to cover the area for the data given below? ▾ Part A S = 1/6500 ; X = 8 f = 152.4mn Express your answer as an integer.
A certain camera is able to focus on objects from 1.13 m to ∞o. Suppose you want to take an extreme close-up shot, with the camera 19 cm from the object. Find the focal length of a thin lens that could be placed directly in front of the camera lens such that the image of the close object would be in focus. (Let's denote the minimum and maximum values of the focal length by fmin and fmax, respectively.) 228 m -u I fmin = fmax = XX
