If you haven’t done so already, read this article first: Don’t get ripped off! Part Seven. Comparison Test One: Telephoto Phone Lens vs DLSR and Zoom Lens. It will explain the background and methodology behind this comparison test.
I purchased the 8-18X telephoto lens to check it out. Like the lens in Comparison Test One, it is another Chinese lens for smart phones. The ads for this lens say this lens is amazingly sharp. It is being sold for $59.99. That is an outrageous price of course. I found one on Amazon for less than $12. I knew when I bought it that it would not be worth $12. I had read other online reviews for this lens which point out how bad it is, but I wanted to see for myself.
