I have a home made filter and lens shade holder that has never let me down. It consists of a thin metal plate that fits on to the camera and in turn screws into the tripod with the camera. On each side of the plate is a plastic threaded socket where I can screw in a 12" to 15" flexible tube with a clip attached. One clip holds any filter I wish to use and the other hold a piece of flat black card that acts as lens shade. The flexible tube is normally used on lathes to carry cooling fluid to the cutting head. I get some strange looks as I wander around the this attachment on my camera, for in addition to it looking like a Cheviot Tup with curved horns (a local male sheep), it is also a mix of rather vivid colours. However, I never have problems when shooting directly into the light and can quickly change filters.
