You may purchase the Vello T-Mount Lens to Nikon F-Mount Camera Lens Adapter, B&H # VELANFT, to connect the Opteka 500mm f/8 HD Telephoto Mirror Lens for T Mount to the Nikon D5000 DSLR camera. Do note that the Opteka 500mm f/8 HD Telephoto Mirror Lens for T Mount is a fully manual lens, and as such, you will have to place the camera in full manual mode and set your exposure manually to use the above lens. The camera's shutter will not release if the camera is not set to full Manual mode.

question

Would this lens be suitable for photographing a solar eclipse (with appropriate filters)?
Asked by: Anonymous
It is capable of producing an acceptable result although not as sharp as a traditional lens. Whilst I have had some success hand-held, a tripod is best as there is no shake reduction with this lens. Be aware that the filters are rear mounted (mine came with an ND filter and a couple of others).

You will need a T mount adapter ($10) and set the camera to manual. The lens is totally manual with a fixed f stop.
