WebFocal Length A typical circular fisheye lens might possess a focal length of 8mm to 10mm for cameras with a 35mm sensor or film. On the other hand, full-frame lenses have slightly longer focal lengths, i.e., usually 15mm to 16mm. Crop Factor Like all other lenses, the focal length is effectively increased for cameras with a sensor below 35mm.
