| Accessory to use 35mm Canon cameras (except EOS models) with Questar camera adapters only. This is for those Canon cameras that use a breechlock lens mount. These have a knurled rotary collar around the base of the lens that must be tightened separately to lock the lens in place. This is not for EOS-type cameras whose lenses click into place with a quarter turn of the entire lens and which use a button on the camera body to release the lens when you want to change it. 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. Standard freight charges ($9.95 minimum) and a 14-day or longer delivery time apply if this item is purchased by itself as a special order item. Additional Questar freight and a $15 Questar drop-ship charge will apply if faster delivery is required and it must be drop-shipped to you from Questar. |
