The Chinese Lens Rip Off! Part Nine. Comparison Test Two: 8-18X Telephoto Phone Lens vs 12X Telephoto Phone Lens

8-18X telephoto lens on an iPhone SE.

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 and 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. Other online reviews for this lens point out how bad it is but I wanted to see for myself.

You click on the link and you read an article that says their telephoto smart phone lens has “been tested, and found to equal or exceed the photos produced by such top makers as Zeiss, Leica, Nikon, Canon and Sony.” It is all utter nonsense of course, meant to fool clueless people into spending $56 or more on a poor quality lens that they could buy for as little as $4.00. So I decided to buy one of these lenses on the cheap and do my own comparison test.

The Chinese Lens Rip Off Series – Overpriced Camera Phone Lenses

The ads show up on FaceBook all the time. They talk about wonderful lenses that will turn your smart phone into a camera that is better than a DSLR costing thousands of dollars. They brag about German engineering, a NASA optical formula, or the testing that proves their lenses are better than expensive lenses from Nikon, Zeiss, Leica, or Canon. The names of the companies change on a regular basis, but the scam is the same. Sad to say, a lot of people actually fall for this nonsense.

Depth of Field and Hyperfocal Distance App for iPhones and iPads

Simple DoF app for iPhone and iPad

My favorite depth of field app for the iPhone and iPad is the “Simple DoF Calculator” by Dennis van den Berg. It is fast, accurate, and simple to use. Best of all – you can set the Circle of Confusion (CoC) to the value of your choosing. In this screen capture of my iPhone the app is marked with a red square.
