| Accessory for use with Canon EOS 35mm auto-focus cameras and Questar camera adapters only. Not for older breechlock lens mount Canons, such as the AE-1, that have a knurled rotary collar around the base of the lens that has to be tightened to lock the lens in place. Needed for prime focus photography (full lunar discs & terrestrial photography), eyepiece projection photography (planetary & close up shots of the moon), and 35mm deep space photography. Shipping is free on this Questar item if it is purchased with a Questar scope that is being drop-shipped to you from the Questar factory.
