The authors seem to have overlooked a source of reviews by people who have not purchased the product. They did purchase the product elsewhere (maybe at retail, or another online site), and wrote the review on whatever page came up when they Googled the product name. This happens often on Amazon, where the same or similar products are available from several sources, and it is clear from the reviewers comments that product they are reviewing is not the specific one offered!Also, I suspect that reviewers as a group are more negative than purchasers as a whole. People seem to be more apt to criticize a product than to say nice things. This is a hypothesis, not a fact. I would love to see a study that addresses this question.

F/2.8 is a newbie's idea of a fast prime. F/1.8 is a skilled photographer's idea of a fast prime.
That, of course, should read"F/1.0 is a better fast prime. F/1.8 is a cheap fast prime :-)
