The Dedolight Slide Holder Attachment with Image Adjustment for 2-1/4 x 2-1/4 (6x6cm)M\ Slides enables projection of your square mounted transparencies onto a set or background, using the Series 400 Imager Projection Attachment.
When projecting a transparency off the axis of the camera, the image plane adjustment adjusts the focus, so that the entire image is sharp -- left to right, top to bottom. Depending on the focal length lens used in the projection attachment, this adjustment is effective to ~45° off-axis.
It includes a high-quality heat reflecting filter, fan, and power supply.
Note:Suggestion: Use duplicate transparencies, NOT originals.
