zmxtech 0 Posted November 25, 2009 From tamron : Your object distance 30 m. To cover a horizontal area of 5 m and a vertical area of 3.75 m, you will need * For 1/3" cameras: a focal length of 28.8 mm. * For 1/2" cameras: a focal length of 38.4 mm. so a 5-50mm lens will be fine z Share this post Link to post Share on other sites
