Consider the Rollei SL26, with 28,000 produced. I have one. It's worth less than $50. Is this a rare camera? 28,000 isn't a big production run for a camera, but rarity, like the descriptors antique and vintage, is subjective. For every one who adheres to a strict definition of the term "rare", a thousand more will throw it about carelessly. I've seen everything from Kodak box cameras to Argus C3s described as rare on eBay. Obviously those terms are meant to attract eyeballs and the money of those that don't know any better.
