[QUOTE="Don Kuykendall_RIP, post: 36039, member: 6277"] Zoom Lenses have a very narrow Depth of Field ([url=http://www.dofmaster.com/dofjs.html]Online Depth of Field Calculator[/url]) so it is difficult to preset the focus. Are you trying to shoot the moon or stars then you can figure out using the chart on the site how far away you need to focus to get the depth of field to infinity. With your lens set to 105mm and F16 you could focus on something at 112 feet and everything between 56.6 ft and infinity would be in focus. but at 112 feet you would only be in focus to 9176 ft which when focusing on the moon would be very far off. Play with the chart and it will help you understand Depth of field. In [URL="http://en.wikipedia.org/wiki/Optics"]optics[/URL], particularly as it relates to [URL="http://en.wikipedia.org/wiki/Film"]film[/URL] and [URL="http://en.wikipedia.org/wiki/Photography"]photography[/URL], [B]depth of field[/B] (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. The nice thing about Digital photography is that you can shoot and look at the results right then. Play with the settings one at the time and see the results.
