Input:
The Canon Angle Finder fits my Canon Digital Rebel and my 1970's Canon FTb for B&W film.  It works perfectly for an SLR camera for getting down to the level of subjects shorter than me, which is just about everybody in the human race.  I use it on nearly every photo shoot when I want a different angle for a photo and keeps me off my knees.  It slips on easily and stays in place.  It's a high-quality optic device at a reasonable price.  It easily fits in a trouser or shirt pocket and comes with a useful case to keep it neat.
