The Canon EF 85mm f/1.8 USM Medium Telephoto Lens is perfect for Canon SLR Cameras. This lens has a ring-type ultra-sonic monitor (USM) which brings subjects quickly into focus. It has a maximum aperture of f 1.8 and a fixed focal length of 85 millimetres. The closest focusing distance ...

Suppose your 41 mm focal length camera lens is 59 mm away from the image sensor in the camera. What is its focal length (in cm) ? Unit Conversion Different countries use the units for measurement according to their convenience however conformable to the S.I unit sys...
necessary the diagonal will do. Solving the equation above for focal length will be (12.7X1016)/609.6 = 21.2mm. This is not a common lens focal length so either the working distance would need to be adjusted or a non-standard lens that allows the user to vary the focal length is ...
