Here is a simple tilt-shift adapter which will attach to any micro four thirds camera body and hold a Nikon Series E 50mm lens. This adapter will create a tilt-shift effect or miniature effect in your photos (see examples below). This is intended to be a more durable and cheaper solution than both DIY and commercial lenses ($2100). It was designed to be part of the "Make It Real Contest" on instructables, so if you dIg it - follow this link and vote for my project. Thanks!
