While the last iPhone telephoto lens that we featured didn’t look too portable, this one sure does. Also, it’s not that expensive. At $35 (USD), you can definitely check it out without feeling too much pain in your wallet.
If you want to get closer to the action than your iPhone will normally allow, PhotoJojo’s 8× zoom lens kit could come in handy. Check out some of this example photo that they were able to take with it:
Not bad, considering that they are using a cheap telephoto lens on an iPhone, which itself doesn’t have the best camera sensor. The lens snaps onto the camera using an included case, and is available for both the iPhone 4 and older 3G/3GS models. There’s a collapsible table tripod that comes with the kit as well, and they even throw in a lens cleaning cloth.
Honestly though, when I want to do high quality telephoto shots, I’ll stick with my DSLR and an 18-200mm lens.
