Cathay Photo is selling a small static brush for $10, a medium size one for $20, and a large one for $26. According to he salesman, it can be use to clean off dust on slides/negative film and lens.
Question : How useful is such a brush? Is it really a useful tool ... something which is better than a jumbo blower and lens tissues and some exhaled breathe ?
