Gerry's baaaack! The evening's tutorial will show you how to test your camera's lenses to assess if each of their fine focus points are accurate. and if they aren't, find out what you can do about it. No need for your hammer or screwdrivers, though your lens or camera manual may be of use.
Bring your camera, lenses, a tripod and a long tape measure so you can participate in this "made to measure" event.
