Apart from the barrel distortion we mentioned earlier, we were exceptionally pleased with the photos we took with the Olloclip. Sure, the compact, dual-sided, three-in-one lens won’t match the image quality of a pro rig, but considering its size and versatility, it may just become the next must-have accessory for Apple’s iPhone 4.
Olloclip is a clip-on 3-in-1 one lens for the iPhone 4 that has fisheye, wide-angle, and macro lenses. Priced at US$69.95.
Update 2012.02.24: Abdel Ibrahim:
The Olloclip, you see, goes for $69, while the iPro Len System will set you back almost three times that, at $199. With that significant price difference in mind, it all comes down to priorities. If youâ€™re looking to get the most out of your iPhoneâ€™s camera and donâ€™t mind a bulkier package or steeper price, the iProâ€™s the way to go. But for casual users whoâ€™d like to spice up their phoneâ€™s camera without breaking the bank or toting around extra hardware, the Olloclipâ€™s just fine. In fact, itâ€™s the newest addition to my arsenal.
The best thing about the Olloclip is the built-in macro lens, something I’ve been looking for for some time. I like taking a closer look at things.
