Focus on a distant object in daylight and then put a piece of tape on
the focusing ring so it can't move.

If you're going to estimate distances be sure that any error is on the long side. If you're under the hyperfocal distance you'll miss infinity. If you're over it you'll just slightly lengthen the minimum focus distance.Hyperfocla is, I think, only going to be useful if I shoot wide-field shots and include some trees or foreground details. Otherwise, I might have bumped the focus collar and gone a tiny bit off of infinity this time. -- _________________________________________________________________ Options: http://lists.thomasclausen.net/mailman/listinfo/olympus Archives: http://lists.thomasclausen.net/mailman/private/olympus/ Themed Olympus Photo Exhibition: http://www.tope.nl/ |
