Title: In a 35 mm single lens reflex camera (SLR) the distance from the lens to the fil Post by: mikael on May 15, 2014 In a 35 mm single lens reflex camera (SLR) the distance from the lens to the film is varied in order to focus on objects at varying distances. Over what range must a lens of 40 mm focal length vary if the camera is to be able to focus on objects ranging in distance from infinity down to 1.1 m from the camera?
A) 1.51 mm B) 1.21 mm C) 4.53 mm D) 6.04 mm E) 2.11 mm Title: Re: In a 35 mm single lens reflex camera (SLR) the distance from the lens to the fil Post by: padre on Jun 11, 2014 AA
