Edgar Cuevas, who publishes the iPhoneogenic blog, recently purchased a T-20 2.0x Telephoto Lens for mobile phone. The T-20 is a low-cost, magnetic mounted telephoto lens made of metal — probably aluminum — and optical glass.
The device works on iPhones as well and Edgar took his new toy for a test drive. His complete review of the device appears on his other blog, Edgar’s iPhone Film Lab.
After successfully purchasing a .67X macro/wide lens and 6.0X telescope for my 3GS, I decided to buy the 2X telephoto because it’s a happy medium between the others just mentioned. After the initial mount to my 3GS I was disappointed. I immediately notice a hard circular vignetting around the lens.
My own thoughts on this particular device…. It’s definitely not a high-quality telephoto lens, but once you finally it the device to mount, it produces some interesting lo-fi color shifts, vignetting and lens barrel distortions. Not exactly what you want in an external telephoto lens, though, where the purpose of such a device is to get higher quality photographs than using the iPhone’s digital zoom.
