Use your Canon EOS lens as optics for CCD photography. The lens adapter can be connected directly to the lens and adapts to the T2 external thread. You can then mount the entire unit on a photo tripod or mount it parallel to the telescope using a suitable prism rail.
Areas of application:
- Photography with CCD and video cameras with Canon EOS lenses
- Use of EOS lenses for autoguiding in astrophotography
For which lenses is the lens adapter suitable: The adaptor is suitable for all CANON EOS lenses (including EF-S) and also for third-party lenses with the Canon EOS bayonet mount.
For which cameras is the lens adaptor suitable: Due to the short optically effective length of the adaptor of only 19 mm, you can adapt almost all CCD cameras, video cameras with C-mount thread and cameras from Imaging Source. Since most cameras have a very small distance between the chip and the connection thread, you may need T2 extension rings to ensure the correct distance between the lens and the camera.
Attaching the lens to the adaptor: Before attaching the lens to the adaptor, please turn the locking ring completely in until it stops. Then turn the lens with the bayonet lock into the adaptor until it stops. Then turn the locking ring out again until the lens is fixed in place.
Practical tips: Lenses always have a standard distance of 45 mm from the bayonet to the focal plane. You therefore need to know the distance from the connection thread of your camera to the chip. A look in the operating instructions usually helps here. Then subtract this measurement from the 45 mm. Then subtract the 19 mm construction length of the lens adapter. This tells you how many millimetres you need to bridge to achieve the optimum camera/lens distance.
